Dependability Evaluation of Automotive Embedded Electronic Systems
The Software Platforms group is part of the Department of Mechatronics & Software and focuses on development, ranging from architecting to implementation and deployment, of embedded software for distributed dependable systems and embedded electronics architectures and platforms.
Thesis Proposal: Dependability Evaluation of Automotive Embedded Electronic Systems
Dependability of SW
Embedded automotive electronic systems (which also include software) are increasingly defining functionality of new features in the automotive area. Even new safety features are implemented largely in software. This puts tremendous pressure on the electronic systems to perform as expected, even in the presence of faults during operation. Therefore, research on new approaches to increase the confidence in electronic systems is focusing on providing extensive features while at the same time not compromising quality, safety and cost.
A challenge is to develop electronic systems which provide services even in the presence of perturbations, i.e., are able to detect faults in the system and react accordingly. For this, appropriate mechanisms must be available and these must be well assessed. Fault injection is a promising approach, in the development of such mechanisms. The anticipated faults are artificially inserted into the system under development and its response is observed.
DEDICATE (Dependability and Diagnostics Concept Assessment and Test) is a 3-year research project focusing on new and innovative diagnostic mechanisms for the electrical/electronic (EE) system of a vehicle. New approaches to handle faults are being researched. Prototypes are developed and evaluated in a realistic setting. This thesis project will contribute to the overall project objectives by developing techniques for evaluating the dependability features of the electronic system.
As part of DEDICATE a fault model for faults in EE systems is developed. The thesis project will continue this work by further evaluating selected faults in a realistic context. The exact goals of the project are to be defined at the thesis project start, but a preliminary list of goals includes:
Defining a technique for quantitative dependability evaluation of automotive electronic systems using fault injection
Extending an existing research tool for fault injection to use the developed evaluation technique
Evaluation of the technique on existing test setup
Developing a methodology for using the proposed technique
The project is suitable for two full time Master students. Supervision will be provided by experienced Volvo Technology engineers and researchers. The work will take place at the Volvo Technology facilities at the Chalmers Science Park in Gothenburg. Apart from the thesis report, students are also expected to give a presentation at Volvo at the end of the project.
Candidates should be in their final year of their Master’s studies. Suitable (Swedish) programmes include E, D, IT or Z, i.e., Electrical Engineering, Computer Science/Engineering, IT, Mechatronics. Candidates with equivalent backgrounds from other programmes will also be considered.
The work requires a basic knowledge in development of embedded software and system modelling. This includes C programming, software testing, real-time systems, dependable systems, distributed systems and operating systems. Knowledge of automotive standards such as AUTOSAR (www.autosar.org), ISO26262 (functional safety), ISO14229 (diagnostics) is considered favourably but is not a requirement.
As the work environment is highly international good English skills are required, both oral and written.
After a successful thesis project students will have gained experience in the field of automotive electronic system development, dependability evaluation and testing. Students will gain experience from modern software platforms and tools used within the automotive industry.
Students will also have an opportunity to gain insights into how research is conducted in industry.
