The BRAKE Project - Centralized Versus Distributed Redundancy for Brake-by-Wire Systems

This paper presents the objectives and preliminary results of the BRAKE project - a joint effort of Delphi Automotive Systems, Infineon Technologies, Volvo Car Corporation and WindRiver. The objective of this project is to use microelectronics technologies to design a distributed Brake-by-Wire system including:

• A distributed fault tolerant system for enhanced safety
• An extension of the OSEK based operating system for a distributed time triggered architecture
• An open interface between vehicle control, and brake system control

The results comprise the requirements, interface specification (see [1]), a full simulation model, a hardware-in-the-loop bench, and a demonstration vehicle. The application has been developed using advanced automatic code generation for Infineon's TriCore based automotive microcontrollers.
