completely distributed automotive electrical system and its design

Abstract:

The development trend of automotive electrical system is analyzed through the distribution index. A complete distributed automotive electronic system is introduced. The new architecture concept features a set of hierarchy backbone and local digital signal network, power supply network together with a central coordination controller. The electrical/electronic devices are connected through backbone/local networks, and are supplied through the distributed power supply network. The harness in this so called Pan-electronic automotive system is standardized and invariant. The system achieves good configurability, extendibility and reliability. A bus as a demonstration is developed and the system is improved feasible and economy.
