Academic literature on the topic 'AUTOSAR; Ethernet'

The transportation industry is facing major challenges that come along with innovative trends like autonomous driving. Due to the growing amount of network participants, smart sensors, and mixed-critical data, scalability and interoperability have become key factors of cost-efficient vehicle engineering. One solution to overcome these challenges is the AUTOSAR Adaptive software platform. Its service-oriented communication methodology allows a standardized data exchange that is not bound to a specific middleware protocol. OPC UA is a communication standard that is well-established in modern industrial automation. In addition to its Client–Server communication pattern, the newly released Publish–Subscribe (PubSub) architecture promotes scalability. PubSub is designed to work in conjunction with Time-Sensitive Networking (TSN), a collection of standards that add real-time aspects to standard Ethernet networks. TSN allows services with different requirements to share a single physical network. In this paper, we specify an integration approach of AUTOSAR Adaptive, OPC UA, and TSN. It combines the benefits of these three technologies to provide deterministic high-speed communication. Our main contribution is the architecture for the binding between Adaptive Platform and OPC UA. With a prototypical implementation, we prove that a combination of OPC UA Client–Server and PubSub qualifies as a middleware solution for service-oriented communication in AUTOSAR.

Automotive Ethernet is a newly introduced in-vehicle bus that allows unicast communication between ECUs. It is based on the OSI model of Ethernet, with a few modifications on the physical layer and newly introduced application protocols. AUTOSAR, a consortium of automotive OEMs, Tier-1 suppliers and tool vendors has defined a standard software architecture that simplifies the ECU software development with its well defined software specifications and APIs. The Automotive Ethernet stack is now an integral part of the latest AUTOSAR specification release 4.2. Infineon Aurix TriCore TC27x microcontroller is a popular board used in ADAS applications. The board has support for Fast Ethernet. This thesis investigates the setting up of an Ethernet communication on the TriCore board running under AUTOSAR software architecture. The various modules of the AUTOSAR Ethernet stack are familiarized and configured. This is followed up by validating the implementation on the Ethernet physical layer. The validation is based on a real Ethernet communication between the TriCore board and the Vector VN5610 network interface card. TCP and UDP based connections between the AUTOSAR compliant board and the VN5610 are tested and validated. A test suite for evaluating the protocol conformance of the AUTOSAR Ethernet stack exists at Bertrandt. The final step of this thesis involved the execution strategies for this test suite.

This diploma project summarizes a theoretical introduction regarding the issue of traffic light control. Further there is industrial communication discussed, where they are the Ethernet / IP protocol and the Modbus TCP protocol described more in detail. The following is the description of the Logix series programmable controllers. Then the diploma follows up with market research in order to find the most suitable development kit which is used as a trial prototype. Then it is concerned with a development kit with a communication module from AND-TECH company. Software was developed on them, more specifically a library for processor ports, memory and the Modbus TCP protocol. After verifying the functionality of the software, the hardware design was started. From the first site it is development kit and module and from the second site there are input and output circuits. There must be the assessment of the results found during the test operation. The end of the document describes incorrect steps that were repaired in hardware.

The evolving of the networking application and electronic components are pushing the bandwidth limits in the automotive domain [19]. Consequently, the car manufacturers have begun to produce more complex Electronic Control Units (ECUs) to fulfil the automotive technology evolution. Car manufacturers have used ECUs from different vendors to get the most creative features in cars [19]. These ECUs requires a standard network interface such as Ethernet which can bring significant features such as high bandwidth, low weight and full duplex communication. Nowadays, Ethernet has adapted to apply in the automotive application. Therefore, it has called for a high degree of testing to ensure the safety and interoperability between these ECUs. However, the testing of the Automotive Ethernet is facing many challenges such as finding and solving the issues as early as possible in the development process. Besides that, testing an Automotive Ethernet TCP/IP stack is a complex task, as it required an upper tester to cause the implementation of the device under the test to move to specific states. AUTOSAR has defined a standardised control protocol (Test Stub) to use it as an upper tester for executing the AUTOSAR Acceptance Test (for TCP/IP stack) [6]. This protocol has used for conducting the test cases of the TCP, UDP and IP protocols in AUTOSAR [21] [22] [23]. OPEN Alliance has specified an Automotive Ethernet ECU test specification which covers more protocols than AUTOSAR such as ARP and DHCP [7]. Consequently, potential gaps and issues may arise when using the Test Stub to conduct the test cases of the OPEN Alliance, as it initially defined for conducting the AUTOSAR Acceptance Test. This work presents the evaluation of the Test Stub in context of using it to conduct the OPEN Alliance Automotive Ethernet ECU Test. Furthermore, it will introduce a solution to overcome the potential issues and gaps which may arise after using the Test Stub (defined by AUTOSAR) to conduct the test cases of the OPEN Alliance.

Topic: Driver Assistance Technology is emerging as new driving technology popularly known as ADAS. It is supported with Adaptive Cruise Control, Automatic Emergency Brake, blind spot monitoring, lane change assistance, and forward collision warnings etc. It is an important platform to integrate these multiple applications by using data from multifunction sensors, cameras, radars, lidars etc. and send command to plural actuators, engine, brake, steering etc. ADAS technology can detect some objects, do basic classification, alert the driver of hazardous road conditions, and in some cases, slow or stop the vehicle. The architecture of the electronic control units (ECUs) is responsible for executing advanced driver assistance systems (ADAS) in vehicle which is changing as per its response during the process of driving. Automotive system architecture integrates multiple applications into ADAS ECUs that serve multiple sensors for their functions. Hardware architecture of ADAS and autonomous driving, includes automotive Ethernet, TSN, Ethernet switch and gateway, and domain controller while Software architecture of ADAS and autonomous driving, including AUTOSAR Classic and Adaptive, ROS 2.0 and QNX. This chapter explains the functioning of Assistance Driving Technology with the help of its architecture and various types of sensors.
