Abstract:

The export demand for Electoric Control Unit (ECU) products, which continued to increase by approximately 25% in December 2014, made the company have to review its production capacity. Based on current production capacity data, it is known that the process cycle time is 64.9 seconds while the takt time needed to meet consumer demand is 39.4 seconds for the first production line. With working time included in working hours overtime, this first-line capacity cannot meet production demands. Work measurement is done to get actual time data for capacity calculation. Man machine chart is one of the tools used to determine the production line capacity with the current number of machines and workers. To be able to fulfill the production demand, a capacity design with 2 proposed improvements is carried out, namely: adding a working time of one shift for the first production line or balancing work time between lines. By calculating the results obtained and the costs incurred, the proposal for balancing work time between lines becomes more effective to do.

Abstract:

The development of advanced thermal management materials for Electronic Control Unit (ECU) is the key to achieving high reliability and thus safety critical operations in areas of ECU applications such as automotives and power systems. Thermal management issues associated with the operation of ECU at elevated temperature have accounted for some of the recent reliability concerns which have culminated in current systems failures in some automobiles. As the functions of ECU in systems have increased in recent times, the number of components per unit area on its board has also risen. High board density boosts internal heat generated per unit time in ECU ambient. The generated heat induces stress and strain at the chip interconnects due to variation in the Coefficient of Thermal Expansion (CTE) and thermal conductivity of different bonded materials in the assembly. Thermal degradation could become critical and impacts device’s efficiency. The life expectancy of electronic components reduces exponentially as the operating temperature rises thus making thermal management pivotal in electronic system reliability. Since materials’ properties vary with operating condition, material performance has become a major consideration in the design of heat dissipation mechanism in ECU. The development of advanced thermal management materials and hence improving the performance of ECU requires an in-depth understanding of the complex relationship between materials’ properties and their behaviours at elevated temperatures. The paper presents an overview of thermal management materials, review trends in material and processing technology. In addition, the paper outlines the crucial challenges in materials, cost and composite formulations and the outstanding R & D issues.

Abstract:

ABSTRAKRacing line merupakan daerah lintasan yang berguna untuk pebalap atau pengemudi mendapatkan akselerasi maksimum. Dalam penelitian mobil listrik, racing line tidak hanya berguna untuk mendapatkan akselerasi maksimum, namun juga berguna untuk mendapatkan hasil efisiensi tertinggi terutama pada saat mobil berada di tikungan, hal ini disebabkan mobil listrik menghasilkan daya yang lebih besar pada saat berada di tikungan dibandingkan dengan lintasan lurus. Pemilihan racing line serta proses kontrol kecepatan pada mobil listrik yang baik pada tikungan bertujuan untuk mengurangi konsumsi daya pada motor serta meningkatkan hasil efisiensi mobil. Untuk dapat meningkatkan hasil efisiensi pada mobil listrik perlu ditambahkan sebuah ECU (Electronic Control Unit) dengan kontrol fuzzy logic sebagai pengendali kecepatan mobil secara otomatis pada saat mobil berada di tikungan, dengan penambahan kontrol fuzzy logic serta sensor sudut belok ini konsumsi daya yang dihasilkan oleh mobil saat berada di tikungan menjadi lebih rendah serta hasil efisiensi mobil lebih tinggi.Kata kunci: Racing Line, Sistem ECU, Logika Fuzzy ABSTRACTIn the research of electric cars, the racing line is not only useful for getting maximum acceleration, but it is also useful to get the highest efficiency results especially when the car is round the corner, this is due to electric cars producing greater power when in a curved compared to a straight track. The selection of a racing line and speed control process on a good electric car on the curved aims to reduce the power consumption of the motor and increase the efficiency of the car. To be able to increase the efficiency of the electric car, an ECU (Electronic Control Unit) is added by fuzzy logic controls as a car speed controller automatically when the car is in the corner, with the addition of fuzzy logic controls and turn-angle sensors. The car when on the curved becomes lower and the results of higher car efficiency.Keywords: Racing Line, ECU System, Fuzzy Logic

Abstract:

Automotive industry is migrating to electronic based control which has promoted the evaluation and enhancement of engine control performance using electronic components in the research field. Modern engines are controlled by Engine Control Unit (ECU) where not only functions and control systems are in placed, but also the fail-safe mechanisms must be integrated in the ECU to ensure user safety when an error occurred. This work focuses on developing a reliable crankshaft function in an ECU using field-programmable gate array (FPGA). ABa test is carried out and the number of occurrences at unintended location are being monitored in the system to detect the random missing tooth. The reliability of the function is tested by evaluating response of the crankshaft function in an ECU when an unexpected missing tooth occurs during its operation. The developed system is able to detect the random missing tooth on a crank trigger wheel at an accuracy of 100% when the wheel is on a run at a constant wheel rotational speed. It also flags error message for further processing in other functional units of the ECU as a safe-fail mechanism for the system. Implementation of the random missing tooth detection in the crankshaft function is shown to work in the system which is developed using Verilog code

Abstract:

The advancement in embedded systems, which includes the mass deployment of internet-connected electronics, allows the concept of Internet of Things (IoT), to become a reality. This paper discusses one example of how an internet-connected embedded system is utilized in an automotive system. An Electronic Control Unit (ECU), which functions as a control unit in a fuel injection system, are equipped with Wi-Fi capability and installed on 110cc motorcycle. The ECU is connected to multiple sensors that is used by the ECU as part of control system, as well as giving raw data in real time to the server by using Wi-Fi as the communication medium. The server will accumulate data transmitted from ECU by using MQTT protocol, chosen due to its minimal data profile. The data can be visualized through web portal, or opened by any other web-enabled devices. The data collected may also be used later for any other purposes, such as On-Board Diagnostics (OBD) system, etc.

Abstract:

The development of embedded software in the automotive industry has reached a level of complexity, which is unmaintainable by traditional approaches. The AUTomotive Open System Architecture (AUTOSAR) was created to standardize the automotive software. In this architecture, the development of software is spread, in general, between three different entities: Original Equipment Manufacturers (OEMs), e.g. Volvo; Tier-1 Suppliers, such as Vector; and Tier-2 Suppliers, for example, Renesas Microelectronics. Another methodology that has emerged is to develop Electronic Control Units (ECUs) domain wise: infotainment, chassis & safety, powertrain, and body and security. To allow inter-domain communication, the state of art for fast and reliable communication is to use a gateway ECU. The gateway ECU is a crucial component in the electrical/electronic (E/E) architecture of a vehicle. In AUTOSAR, a third party, different from the car manufacturer, typically implements the gateway ECU. A major feature for a gateway ECU is to provide highly flexible configuration. This flexibility allows the car manufacturer (OEM) to fit the gateway ECU to different requirements and product derivations. This thesis investigates the implementation of post-build configuration for a gateway ECU. First, the thesis provides the reader with some background on AUTOSAR and the current E/E architecture of the gateway ECU. The protocols used by the gateway are explained. The design of a potential solution and its implementation are discussed. The implementation is evaluated through regression tests of the routing functionality. Processing time, memory use, and scaling of the solution are also taken into account. The results of the design and the implementation if judged adequate could be used as a springboard to allow post-build in an existing gateway ECU architecture. The results could consolidate the path towards full conformance to AUTOSAR.
Inbyggda system har okat i fordonsindustrin. Utvecklingen av dessa inbyggda programvara har varit komplex och ar inte genomforbar per ett enhet. Idag ar utvecklingen gjort av tre foretag: en OEM (Original Equipement Manufacturer), Tier-1 leverantorer som tillhandahaller mjukvara till OEMs, Tier-2 leverantorer som tillhandahaller elektroniska styrenheter (ECU) hardvaror. Förmedlingsnod ECU är en viktig komponent i ett fordons elektriska/elektroniska (E/E) arkitektur. En tredje part implementerar, som skiljer sig från OEM, de flesta funktionerna av den förmedlingsnod ECU. En viktig egenskap för en förmedlingsnod är att tillhandahålla en mycket flexibel konfiguration. Denna flexibilitet tillåter (OEM) att anpassa förmedlingsnod till olika kraven och fordonarkitekturer. Denna avhandling undersöker genomförandet av Post-build konfigurationen, ocksa kallad dynamisk konfigurationen för en förmedlingsnod ECU. För det första gers bakgrund på AUTOSAR och den nuvarande E/E arkitekturen för den ECU. De kommunikation protokoll som används förklaras. Utformningen av en potentiell lösning och dess genomförande diskuteras. Implementeringen utvärderas genom regressionstest av routingsfunktionaliteten. Behandlingstid, minneseffektivitet och skalning av lösningen beaktas också. Resultaten av konstruktionen och genomförandet om det bedömdes som lämpligt skulle kunna användas som ett springbräda för att möjliggöra postbyggnad i en befintlig förmedlingsnod arkitektur. Resultaten kan konsolidera vägen mot full överensstämmelse med AUTOSAR.
Le développement de systèmes embarqués dans l’industrie automobile a atteint un niveau de complexité très élevé. D’où la nécessité de créer de nouvelles méthodologies. AUTomotive Open Architecture (AUTOSAR) a été créé pour la mise place de standards pour le développement dans l’industrie automobile. Dans l’architecture AUTOSAR, le développement de logiciels embarqués est reparti, en général, entre trois partis : Original Equipement Manufacturer (OEM), Renault par exemple. Le deuxième niveau regroupe les fournisseurs de logiciels et outils, par exemple, Elektrobit. On retrouve en troisième position les Tier-2 suppliers, fournisseurs de cartes électroniques pour l’automobile, comme Renesas ST. Le développement de calculateurs est séparé par domaine : Multimédia, châssis, motorisation et intérieur. La communication inter-domaine passe par un calculateur passerelle. Le calculateur passerelle est essentielle dans l’architecture électronique du véhicule. Dans AUTOSAR, le calculateur est fourni par un tiers parti, différent du constructeur automobile. Il est donc nécessaire pour le constructeur d’être capable de configurer le calculateur passerelle, sans repasser par le vendeur. Par exemple, le constructeur peut décider, réception du software de rajouter une nouvelle route dans la passerelle. Cet aspect est connu sur le nom de Post-build Configuration dans AUTOSAR. Le but de ce stage est le design et l’implémentation de Post-build configuration d’un calculateur passerelle. D’abord, AUTOSAR et l’architecture électronique d’un calculateur passerelle sont détaillées. Les protocoles de communication sont aussi décrits. Ensuite, le design et les choix d’implémentation sont discutés. L’implémentation est évaluée avec des tests de régression sur les fonctionnalités de routage. Aussi, la solution finale est évaluée sur les critères de performance de routage, l’efficacité en consommation mémoire et la capacité d’être intégrée dans un produit final.

Abstract:

Nowadays almost all motorized vehicles use electronic control units (ECUs) to control parts of a vehicle’s function. A good way to understand a vehicle’s behaviour is to analyse logging data containing ECU internal variables. Data must then be transferred from the ECU to a computer in order to study such data. Today, Keyword Protocol (KWP) requests are used to read data from the ECUs at Scania. The method is not suitable if many signals should be logged with a higher transfer rate than the one used today. In this thesis, communication protocols, that allow an ECU to communicate with a computer, are studied. The purpose of this master’s thesis is to examine how the transfer rate of variables from Scania’s ECUs to a computer can become faster compared to the method used today in order to get a more frequent logging of the variables. The method that was chosen was implemented, evaluated and also compared to the method used today. The busload, total CPU load and CPU load for the frequency used during the experiments, 100 Hz, was also examined and evaluated. The experiments performed show that the method chosen, data acquisition (DAQ) with CAN Calibration Protocol (CCP), increased the transfer rate of the internal ECU variables significantly compared to the method using KWP requests. The results also show that the number of signals have a major impact on the busload for DAQ. The busload is the parameter that limits the number of signals that can be logged. The total CPU load and the CPU load for 100 Hz are not affected significantly compared to when no transmissions are performed. Even though the busload can become high if many variables are used in DAQ, DAQ with CCP is preferable over KWP requests. This is due to the great increase in transfer rate of the ECU internal variables and thus a great increase in the logging frequency.
Nuförtiden används styrenheter (ECUer) för att styra delar av ett fordons funktion i så gott som alla motoriserade fordon. Ett bra sätt att förstå ett fordons beteende är att analysera loggningsdata som innehåller interna styrenhetsvariabler. Data måste då överföras från styrenheten till en dator för att data ska kunna studeras. Idag används Keyword Protocol-förfrågningar (KWP-förfrågningar) för att läsa data från Scanias styrenheter. Metoden är inte lämplig om man vill logga många variabler med en högre överföringshastighet än den som används idag. I detta examensarbete studeras kommunikationsprotokoll som tillåter en styrenhet att kommunicera med en dator. Examensarbetets syfte är undersöka hur överföringshastigheten av variablerna, från Scanias styrenheter till en dator, kan ökas jämfört med den metod som används idag för att få en mer frekvent loggning av variablerna. Metoden som valdes implementerades, utvärderades och jämfördes med metoden som används idag. Busslasten, totala CPU-lasten och CPU-lasten för den frekvens som användes under experimenten 100 Hz har också undersökts och evaluerats. De utförda experimenten visar att den valda metoden, data acquisition (DAQ) med CAN Calibration Protocol (CCP), ökade överföringshastigheten av de interna styrenhetsvariablerna betydligt jämfört med metoden KWP-förfrågningar. Experimenten visar också att antalet signaler har stor inverkan på busslasten för DAQ. Busslasten är den parameter som begränsar antalet signaler som kan loggas. Den totala CPU-lasten och CPU-lasten för 100 Hz påverkas inte betydligt jämfört med när inga överföringar görs. DAQ med CCP är att föredra framför KWP-förfrågningar även om busslasten blir hög för DAQ då den stora ökningen i överföringshastighet av de interna styrenhetsvariablerna medför en mer frekvent loggning av variablerna.

Abstract:

In an automotive context today’s need of testing functions while in factory, correcting faults in the workshop or adding extra value in the aftermarket makes it very important to easily be able to download new software to the electronic control units in vehicles. In the platform for standard automotive software development called AUTOSAR, two known protocols are presented to specify the procedure on how to implement this download operation: Unified Diagnostic Services (UDS) and the Universal Measurement and Calibration Protocol (XCP). However the part of the UDS and XCP standards that is about reprogramming is not completely a part of the AUTOSAR standard yet. In this thesis, UDS and XCP have been compared to evaluate which of the two that has most support in AUTOSAR today and are most likely to be fully integrated into AUTOSAR in the future. Since UDS already has support in AUTOSAR for some of the functions needed for reprogramming and because of the fact that UDS is a part of the extensively used On-board Diagnostic standard (OBD-II), UDS is chosen to be the most suitable protocol for implementing reprogramming functionality according to AUTOSAR. A bootloader with the ability to download data has been developed using only relevant functions from UDS and following the AUTOSAR specifications where it is applicable.
För att kunna testa fordonsfunktioner i fabriken, åtgärda mjukvarufel under service eller för att uppgradera fordonet med nya funktioner är det viktigt att kunna ladda ner ny mjukvara till fordonets styrsystem. Den standardiserade mjukvaruplattformen för fordonsindustrin, AUTOSAR, innehåller två protokoll som båda specificerar hur mjukvara kan laddas ner: Unified Diagnostic Services (UDS) och Universal Measurement and Calibration Protocol (XCP). Tyvärr är de delarna av UDS och XCP som beskriver mjukvarunerladdning inte en del av AUTOSAR än. I det här examensarbetet har UDS och XCP jämförts för att utvärdera vilken av de båda som i dagsläget har störst stöd för nerladdning av mjukvara i AUTOSAR och vilken som troligast kommer att bli en del av AUTOSAR i framtiden. Eftersom AUTOSAR redan stödjer några av de funktioner i UDS som behövs för nerladdning av mjukvara samt på grund av att UDS är en del av branschstandarden för fordonsdiagnostik OBD-II, har UDS valts som den mest lämpade att i dagsläget användas för att implementera nerladdning av mjukvara enligt AUTOSAR. En bootloader som stödjer nerladdning av mjukvara via UDS har sedan implementerats enligt AUTOSAR-specifikationen så långt som möjligt.

Nas últimas décadas, a indústria automobilística mundial vem investindo no desenvolvimento tecnológico dos motores, com o objetivo de alcançar melhor eficiência energética e atender às legislações que limitam a quantidade de resíduos tóxicos nos gases de exaustão e menor consumo de combustível. Isso resultou na implantação dos sistemas de gerenciamento eletrônico do motor, que possibilitam funcionalidades para se controlar diversas variáveis do motor, aumentando consideravelmente o rendimento do motor. Este trabalho tem como objetivos explorar a dinâmica de um motor de combustão interna ciclo Otto, os sinais elétricos associados, e os componentes de seu gerenciamento eletrônico. A partir dessas informações, o trabalho apresenta o processo de analise dos sinais elétricos e as estratégias de controle utilizadas em um sistema de gerenciamento real. Assim, são desenvolvidos o hardware e o firmware de uma unidade microcontroladora para gerenciamento eletrônico do motor. O hardware foi elaborado com uma concepção centralizada, ou seja, foi usado apenas um microcontrolador de 32-bit para gerenciar todas as funções. O firmware de controle foi desenvolvido de forma modular baseado em modelos de malha fechada. O modelo matemático do motor foi identificado utilizando técnicas de controle em um veículo real, e a avalidação do modelo foi obtida através de testes em um dinamômetro inercial.
In the last few decades, the world automotive industry has invested in the technological development of the engines, aiming to get better energetic efficiency and comply with legislations that limit the amount of toxic exhaustion gases. This resulted in electronic management systems for engines, which allowed flexibility to control several engine-related variables, considerably increasing the engine efficiency. This work aims to explore the Otto cycle combustion engine dynamics, its electronic signals, and the elements of its electronic management. Based on that information, this work presents the analysis process of the electronic signals, and the control strategies used in a real management system. Then, the hardware and firmware of a microcontroller unity are developed for the electronic management of the engine. The hardware was elaborated with a centralized concept, i.e., only one 32-bit microcontroller was used to control all functions. The control firmware was developed in a modular scheme, based on the closed loop models. The engine mathematical model was identified using control techniques in a real engine. The results were obtained by tests in an inertial dynamometer.

Abstract:

Controller Area Networks (CAN&rsquo
s) in vehicles need highly sophisticated software tools to be designed and tested in development and production phases. These tools consume a lot of computer resources and usually have complex user interfaces. Therefore, they are not feasible for vehicle service stations where low-performance computers are used and the workers not very familiar with software are employed. In this thesis, we develop a measurement, calibration, test and diagnosis program -diaCAN- that is suitable for service stations. diaCAN can transmit and receive messages over 3 CAN bus channels. It can display and plot the data received from the bus, import network message and Electronic Control Unit (ECU) configurations, and record bus traffic with standard file formats. Moreover, diaCAN can calibrate ECU values, acquire fault records and test vehicle components with CAN Calibration Protocol functions. All of these capabilities are verified and evaluated on a test bed with real CAN bus and ECUs.

Abstract:

This paper presents an approach for an automated calibration process for electronic control units (ECU) of power split transmissions in agricultural tractors. Today the calibration process is done manually on a prototype tractor by experts. In order to reduce development costs the calibration process is shifted from prototype testing to software modelling. Simultaneous optimization methods are used within the software modelling to calculate new parameters. The simultaneous optimization includes objective evaluation methods to evaluate the tractor behaviour. With the combination of both methods inside the software modelling, the calibration process can be automated. The success of this approach depends on the quality of the software modelling. Therefore the identification of the initial prototype behaviour and the fitting of the tractor software model is done at the beginning. At the end of the automated calibration the validation and fine-tuning of the calculated parameters are done on the real tractor. These steps are condensed to a five step automated calibration process which includes simultaneous optimization and objective evaluation methods in several applications. After the detailed discussion of this automated calibration process one function of the ECU (one transmission component) will be calibrated through this process as example.

Abstract:

This paper presents model-based design and hardware-in-the-loop (HIL) simulation of engine lean operation. The functionalities of the homogeneous combustion subsystem in engine Electronic Control Unit (ECU) in dSPACE Automotive Simulation Models (ASM) are first analyzed. To control the gasoline engine in lean operation without the drop of output torque, the combustion subsystem in engine ECU is modified by introducing two control loops, torque modifier and fuel multiplier. The performance of these two controllers is evaluated by HIL simulation using a dSPACE HIL simulator. The HIL simulation models, including vehicle plant model and softECUs in HIL simulator and engine lean control model in hardware engine ECU are modeled using model-based design. With HIL simulation, the designed engine control strategies can be immediately tested to evaluate the overall vehicle performance. The HIL simulation results show that the designed lean combustion control strategy can reduce fuel consumption and is able to meet the torque requirement at lean engine operating conditions.

Abstract:

For design of automotive airbag electronic control units (AB ECU), it is essential to have a validated and reliable finite element (FE) simulation model in place in order to allow already in an early design stage for the accurate prediction of the ECU’s structural vibration behavior. A “bottom-up” approach which described in the ASME guide for verification and validation (ASME V&V 10-2006) is applied for the validation of the AB ECU simulation model. The AB ECU is decomposed into different assembly level. Single printed circuit board (PCB) is the lowest elementary component level. In the PCB level simulation and validation, the influence of in-plane pre-stress on PCB’s transverse vibration characteristic has been encountered, but it has been found out that the source of the in-plane pre-stress can not be explained by classical beam/plate theory. Analysis and simulation for PCB fixation reveals that the fundamental source of the in-plane pre-stress is structure’s geometric nonlinearity.

Abstract:

This paper presents some of the work done to model the dynamics of TRW’s semi-active roll control (SARC) actuator. The SARC system is designed to reduce vehicle body roll in a turn and to allow for improved ride and handling while driving straight ahead. The SARC system consists of a hydraulic actuator, vehicle state sensors and an electronic control unit (ECU). The vehicle state sensors and ECU are optional in that existing ESC/VSC elements could be used to control the actuator with the proper control algorithms. The actuator is a compact hydraulic unit consisting of a linear actuator, pressurized reservoir, and associated valves. It mounts between one end of the sway bar and the vehicle suspension, and essentially works to engage or disengage the sway bar. The model was developed to understand and predict the dynamic behavior of the actuator for simulated vehicle inputs. The model was developed in Matlab/Simulink and was validated against experimental test rig data. Model parameters were determined from experimental data and basic engineering principles. This included modeling the dynamics of the seal frictions and the multi-stage control valve. Different vehicle inputs were simulated and the behavior of the actuator under various load regimes was matched to experimental test-rig data. The results show that this model is a reasonably accurate representation of the dynamics of the physical system allowing for usage in controller development and synthesis, and integrating in to vehicle models for integrated software-in-loop (SIL) and hardware-in-loop (HIL) development.

Abstract:

The performance of a conventional model-based controller significantly depends on the accuracy of the modeled dynamics. The model of a plant’s dynamics is subjected to errors in estimating the numerical values of the physical parameters, and variations over operating environment conditions and time. These errors and variations in the parameters of a model are the major sources of uncertainty within the controller structure. Digital implementation of controller software on an actual electronic control unit (ECU) introduces another layer of uncertainty at the controller inputs/outputs. The implementation uncertainties are mostly due to data sampling and quantization via the analog-to-digital conversion (ADC) unit. The failure to address the model and ADC uncertainties during the early stages of a controller design cycle results in a costly and time consuming verification and validation (V&V) process. In this paper, new formulations of the first and second order discrete sliding mode controllers (DSMC) are presented for a general class of uncertain linear systems. The knowledge of the ADC imprecisions is incorporated into the proposed DSMCs via an online ADC uncertainty prediction mechanism to improve the controller robustness characteristics. Moreover, the DSMCs are equipped with adaptation laws to remove two different types of modeling uncertainties (multiplicative and additive) from the parameters of the linear system model. The proposed adaptive DSMCs are evaluated on a DC motor speed control problem in real-time using a processor-in-the-loop (PIL) setup with an actual ECU. The results show that the proposed SISO and MIMO second order DSMCs improve the conventional SISO first order DSMC tracking performance by 69% and 84%, respectively. Moreover, the proposed adaptation mechanism is able to remove the uncertainties in the model by up to 90%.
