Evaluation of Microcontroller Simulation for Transmission Control Units of Passenger CarsManiruzzaman, Md 14 November 2019 (has links)
Transmission Control Unit (TCU) is an essential part of automatic transmission operation in modern vehicles. TCUs control the switching behavior of an automatic transmission system with a control Software, which takes direct input from the sensors as well as from the engine control unit and makes driving a vehicle much optimum and dynamic as well as provides fuel efficiency. Thus, developing intelligent and sophisticated control software for the TCUs is crucial.
To ensure an optimal performance from the TCUs, proper testing of the control software has shown significant results. Software in the Loop (SIL) testing is the one that comes into the consideration when it comes to testing and verification of control software. With the increasing level of complexities in the software modules, the testing of the codes in a real hardware is very complex, risky and expensive. Whereas a SIL simulation promises to provide a much faster and effective testing system without using a real hardware and to improve the development process.
This thesis evaluates the possibility of using a microcontroller simulation for the SIL simulation of control software. The simulations of Transmission Control Unit of vehicles are primarily done by building an executable for PCs. This executable differs from the actual software (hex) that’s flashed into the controller. Thus, there are two separate development processes for the simulation and the controller. To solve this, a single simulation of the controller is considered as a solution. But, simulating a whole controller is a very complex and expensive procedure which is not available explicitly. Hence, simulation of the microcontroller is a viable and affordable option at this point of time.
For the purpose of simulation during this thesis work, AURIX TriCore from Infineon Technologies has been chosen as the target controller; which is a high-end microcontroller with 32-bit architecture and preferred in a lot of automotive applications. As for a simulation tool, the Universal Debug Engine from PLS GmbH has been selected for its ability to provide the required criteria. A prototype environment has been imagined and implemented which includes a Program to be flashed on the target controller, simulation of the same code into the simulator and finally, running this simulation results along with the SIL environment. The necessary criterion to run the simulation has been documented herewith.

Development of a Control System and Microcontroller Implementation for an Advanced Rotor Technology DemonstratorSaroleeya, Jeemeet 30 October 2023 (has links)
The original idea of the thesis was realized to control the electric drive of the rotor with a special feature. Without using a complex mechanism, the angle of each blade of the rotor can be controlled individually. The blades are fixed independently to a permanent magnet and the housing encompassing the rotor contains coils. By powering the coils, the whole rotor turns into a permanent magnet motor and by using a control algorithm, each blade can be separately driven.
In the first chapter, the introduction to the main idea of the research project is described along with working principle of rotor blade. The basic concept of blade angle is introduced.
The second chapter is the state of Technique. In this chapter, the working principle and basics of permanent magnet synchronous machine and brushless motor with
mathematical model is described. Also, space vector pulse width modulation and double acting piezoelectric actuator model for helicopter rotor are explained.
The third chapter is the overall description of the initial status of the research project.
This part includes the basic principle of the control system, sensorless field-oriented control of Permanent Magnet Synchronous Machine (PMSM). Also, the motor
parameters calculated from the python script of motor design are listed in tabular form.
The fourth chapter focuses on control strategy implementation. First of all, the criteria for selecting the microcontroller are described. After that, the structure of the program with a flow chart was explained. Also, a short description is mentioned of how space vector pulse width modulation is applied. The main function of the position and speed controller with block diagram is explained. Moreover, back-EMF based observer and EKF-based observer are described.
In the fourth chapter, the initial problem of the research project is discussed. To overcome this problem, a set of experiments is carried out.
In the last chapter, the result of the experiment with proper explanation is summarized. Further on the future work to solve the problem is listed.

AVR-Ethernet - Mikrocontroller im NetzHeik, Andreas 17 May 2010 (has links)
Der Vortrag zeigt Grundlagen und Möglichkeiten der Programmierung
von ATMEL-Mikrocontrollern am Beispiel des ATMega32 (ATMega 644).
Der integrierte USART-Baustein wird beispielhaft für Debugging
und als Interface für einen Bootloader vorgestellt.
Für die Kommunikation im Netz wird ein Ethernetcontroller (ENC28J60)
am SPI-Interface angebunden. Am Beispiel der TCP/IP-Implementierung
von Ulrich Radig wird die Funktionsweise erläutert.
Die Anbindung von Sensoren (z.B. OneWire Temperatursensor) runden den Vortrag ab.

Secure Communication in a Multi-OS-EnvironmentBathe, Shivraj Gajanan 02 February 2016 (has links) (PDF)
Current trend in automotive industry is moving towards adopting the multicore microcontrollers in Electronic Control Units (ECUs). Multicore microcontrollers give an opportunity to run a number of separated and dedicated operating systems on a single ECU. When two heterogeneous operating systems run in parallel on a multicore environment, the inter OS communication between these operating systems become the key factor in the overall performance. The inter OS communication based on shared memory is studied in this thesis work. In a setup where two operating systems namely EB Autocore OS which is based on AUTomotive Open System Architecture standard and Android are considered. Android being the gateway to the internet and due to its open nature and the increased connectivity features of a connected car, many attack surfaces are introduced to the system. As safety and security go hand in hand, the security aspects of the communication channel are taken into account. A portable prototype for multi OS communication based on shared memory communication with security considerations is developed as a plugin for EB tresos Studio.
