Objective
The project BRAKE develops a new open system architecture to allow interoperability and portability of safety critical automotive real-time systems build by multiple suppliers and by multiple technologies. The modules are distributed over a cluster of networked embedded control units to build up a vehicle-level system control strategy. No longer a system is controlling just a part of the car, but approaching chassis control the global vehicle behaviour is the control target. Now communication links within a control unit (extended OSEK) and between control units (reliable bus) will have to encapsulate faults within the modules. A global vehicle modelling and simulation approach is used to co-design and co-verify the deliverables of this project in a virtual environment. The architecture is proven in the realm of a brake-by-wire system with strong safety demands. A demonstrator vehicle will prove the correctness of the architecture and the tools.
Objectives:
Failure tolerant features in automotive systems have to become part of global automotive control system. The innovative approach of a distributed architecture, addressed under this project, yet is quite challenging, but offers a promising possibility. The advantage is an improvement of safety and an increase of functionality, but also a reduction of cost.
In this view the objective of this project is to deploy micro-electronics technologies to enable an advanced distributed Brake-by-Wire system comprising:
- An innovative distributed fail-safe system at vehicle level
- Electronic devices enabling this application
- Expanding an existing OSEK based OS for a distributed time triggered architecture
- Defining an open interface in-between car system control, brake control modules, and brakes.
Work description:
The project will cover four major areas of work:
The project will achieve its objective by means of the following major results:
Distribute a control over multiple subsystems at vehicle level;
Enable vehicle control by defining an open interface in-between subsystems;
Provide a safety architecture based on system distribution;
Validate a distributed system through vehicle level simulation;
Expand an OSEK operating system to provide a distributed operating system;
Consolidate a communication scheme to link distributed systems;
Develop software tools and hardware devices to support system distribution.
