Abstract:

Drivers must communicate with other road users to make their intentions clear, thereby enhancing the quality of the driving experience, improving safety on the roads and avoiding accidents. This interaction can be made either formally using legal signals approved by legislative bodies (e.g. use of indicators), or informally (e.g. hand gestures). However, this informal interaction may not be clearly understood by all drivers, and may lead to stress, strong emotional responses or aggressive driving behaviour. Moreover, a single informal interaction, e.g. flashing the headlights, can have several

L’inverterizzazione dei sistemi a motore sta diventando sempre più diffusa sulle più varie applicazioni grazie al risparmio energetico ed economico che questa ha introdotto. Nonostante gli switch di nuova generazione stiano cominciando a entrare in questo mercato, la maggior parte dei sistemi sfrutta ancora gli IGBT. Per poter ulteriormente ottimizare le prestazioni energetiche dei sistemi inverter, i tempi di transitorio devono essere ridotti e l’energia del singolo evento di switch diminuita. In questo modo sarebbe possibile a parità di frequenza di switch usare meno energia o, a parità di

Abstract:

There is tendency for using lot of electromechanical drives instead of mechanical to create more automatic and convenient systems. This means increase of number of DC motors in different devices such as cars, air conditions, computers, household appliances, manufacture machines etc. All this motors have to be driven in different operation modes. Such parameters as rotation speed, current angle, torque, noise should be controlled. Fully integrated DC Motor driver is the cheapest and the most smart solution.

A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis. The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC

Abstract:

Motor vehicles passing cyclists too closely is both unsafe and feels unsafe. The aim of this research was to increase understanding of the factors that influence passing distances and perceived risk, using the Comfort Zone Model. The Comfort Zone Model predicted the factors influencing the passing distances chosen by drivers which include traffic, road, and cyclist attributes. Passing distances and other factors such as motor vehicle speed, vehicle size and car parking then predict the perceived risk of passes for both cyclists and drivers.

Abstract:

Older adults are at an increased risk for motor-vehicle collisions (MVCs) once distance driven is considered, a finding that is partly attributed to a decline in attention related processes associated with age. MVCs typically occur in highly specific areas, suggesting a role of the complexity of the driving environment contributing to the occurrence of MVCs. The goal of this thesis was to explore the attentional demands of simulated driving events of varying complexity among young, mature and older drivers.

Step motors are motion control mechanisms that convert digital pulses into mechanical shaft rotation. They provide high precision positioning and repeatability of movement without a closed loop control, which is preferable for industrial applications in which accurate positioning control is needed. In this thesis, design and realization of a step motor driver will be performed using micro-stepping, which is based on controlling the current of each winding of the motor continuously and solves noise and resonance problems as well as providing an increase in accuracy and resolution.

Due to its high degree of generality, the UFO controller is compatible with all the existing field oriented controller: rotor, stator and airgap flux field oriented controller. In this thesis, the stability regions of these three types of controllers are compared. However, correct estimation of the machine parameter is

The direction of motor’s rotation is irrelevant with motor’s current. Compared with other motor driver systems, the SR motor driver structure is simple, the upper and lower arms of power inverter have not led the conduct danger at the same time and stator and rotor component do not all have permanent magnet. It is suitable for the variable speed control system. The paper utilizes the analysis software of the electri

First, the mechanism and operation of BLDCM is presented. Second, the driver for threephase BLDCM is developed. Finally, the approach to measure speed motor based on its hall sensor is introduced. BLDCM operation can be achieved by controlling its commutation sequence from hall sensors output. Furthermore, when the motor is rotating, the speed of motor can be estimated by using one of hall sensor output. Th

However, using hall position sensors to detect the rotor position, the control system of the BLDCM becomes very unreliable, in harsh environments. Therefore, in order to improve the BLDCM’s capabilities, the purpose of thesis focuses on developing BLDCM drivers utilizing the ST72141 microcontroller without the dedicated hall position sensors.

With an improved driver circuit, the PMOS problem is fixed, the three-phase brushless DC motor speed is increased, and the heat dissipation performance is improved. In addition, this study also improves both the relative position of the Hall sensors and the control of the sine wave driver so that the circuit can get better input signals.
