Abstract：The central coordinators in automotive electric and electronic networks control all the electrical devices in the vehicle, so they need to be very reliable. This paper describes a congruent duplex redundant central coordinating system for automobiles. The two central coordinators are congruent in both their hardware and software. They communicate through the controller area network (CAN) bus, vote by sending and receiving arbitration frames, and monitor each other by sending and receiving status frames. They work as the master and assistant coordinators. When one of them fails, the other takes over the task and sends a warning message to the driver. Tests validate that the congruent duplex redundant central coordinating system can work well in vehicles. The congruent duplex redundant method improves the system reliability and mean life without design and manufacturing cost increases.
