Mission confiée

Vehicle automation is nowadays emerging in many forms and automation comes with many social implications. In order to take full advantage of automation, electric, connected and automated (ECA) vehicles need to be trustworthy. Consequently, there is a strong need for an independent and reproducible validation of automated vehicles even in presence of nondeterministic elements. Independent validation is fundamental to emphasise the capability and safety of any solution in the ECA vehicles space. It is vital that appropriate and audited testing takes place in a controlled environment before any deployment takes place. As the software and hardware components come from multiple vendors and integrate in numerous ways, the various levels of validation required must be fully understood and integration with primary and secondary parts must be considered.

The EU ArchitectECA2030 project aims at implementing a unique in-vehicle monitoring device able to measure the health status and degradation of the functional electronics empowering model-based safety prediction, fault diagnosis, and anomaly detection. A validation framework comprised of harmonized methods and tools able to handle quantification of residual risks using data different sources (e.g. monitoring devices, sensor/actuators, fleet observations) is provided to ultimately design safe, secure, and reliable ECA vehicles with a well-defined, quantified, and acceptable residual risk across all levels of electronic components and systems (ECS). The proposed methods include automatic built-in safety measures in the electronic circuit design, accelerated testing, residual risk quantification, virtual validation, and multi-physical and stochastic simulations.

The goal of this PhD thesis is to apply formal methods for studying the failure modes, fault detection capabilities, and residual risks in the actuators, propulsion systems, and connectivity systems of ECAs. This comprises a formalization of the requirements for fault detection using qualitative and quantitative properties interpretable on behavioural models of tasks and applications. The behavioural models will be exploited to generate automatically high-coverage test suites by means of advanced conformance testing techniques. Quantitative extensions of these models will be exploited to quantify and analyse risk propagation. Finally, formal modelling and validation techniques (model checking, test generation, co-simulation) will be employed to assess the fault detection tool developed in the project.

The PhD will be carried out in the CONVECS project-team of the Inria Grenoble – Rhône-Alpes Centre. The activities of CONVECS focus on the formal modelling and verification of asynchronous concurrent systems, which are instantiated in various domains (communication protocols, distributed algorithms, embedded systems, etc.). To this aim, CONVECS proposes new formal languages for specifying the behaviour and the properties of concurrent systems, and devises efficient verification algorithms and tools running on sequential and massively parallel machines. The research results of CONVECS are instantiated in the CADP verification toolbox (http://cadp.inria.fr), which is widely used in academia and industry.
