Dependable distributed embedded systems (DDES) are being deployed widely in automobile industry over the world. These systems always post rigorous requirement for timing accuracy and reliability. Both hardware and software architecture have important effect on the system dependability. Adding or substitute for more reliable hardware could increase the system reliability moreover achieves faster system response. Apparently this would increase the manufacturing cost, while software could be a more cost-effective ways for providing support for dependable distributed embedded system development. The dependable distributed embedded system assessment platform (DDESAP) which based on vehicle control system provides testing and assessment support for various automobile dependable software. DDESAP evaluates the vehicle control hardware and operational environments. Software architectures such as time- triggered, event-triggered, hybrid-triggered and other fault tolerant mechanisms for dependable distributed embedded systems were tested on DDESAP. A vehicle dynamic model, a motorway traffic model, and a driver model were developed for DDESAP. Simulation show these models comply with manufacturer and empirical data. DDESAP enables the evaluation of novel software architectures for safety-critical automobile control systems, like the fault tolerant adaptive cruise control systems (ACCS) presented.
