Abstract: The ant colony algorithm was used to design PID controller of traction control system, whose parameters could be adjusted automatically. A software-in-the-loop simulator and a hardware-in-the-loop test bench were erected, the controller parameters were debugged and calibrated, and the algorithm based on lookup table was obtained to meet realtime requirement. The hardware-in-the-loop tests on typical roads were made and the test results show that the control algorithm can improve the vehicle accelerating performance on the low adhesion road effectively.
