Simulation of Acceleration Slip Regulation for vehicle based on CAN bus

A CAN bus integrating the engine ECU and the vehicle anti-slip regulation ECU was developed for Vehicle Acceleration Slip Regulation (ASR) based on the SAE protocol J1939. Then the ASR system simulation model with CAN bus was built in CANoe-Matlab, and the ASR CAN network was simulated with fuzzy-PID control algorithm in Co-simulation method. The results show that it is feasible and real-time to control engine throttle with communication between ASR ECU and engine ECU through CAN bus, the fuzzy-PID controller can effectively prevent the excessive spin of driving wheels on slip roads and improve the driving ability of the vehicle, and this system also provides a more convenient way for the vehicle integrated control and development of ASR controller with CAN bus.
