| Abstract: | A CAN Bus communication network of high dependability and high real-time in automobile electronic system is designed. Proposing two CAN Buses, the high speed one connects the electronic control devices with high real-time demand and low-speed one with low ones, Two CAN Buses communicate by Gateway. Central control module and central control system based on PC are designed. Data chain layer and physics layer follow CAN2.0B technical specification. Experimental results prove proposed system is effective and feasible. |
