Fuzzy PID Control Algorithm for Vehicle Accelerating on Spit μ Road

摘要

This paper relates to a traction control algorithm of automobiles on u split road that the target wheel slip ratio is varying according to road friction coefficient and vehicle reference speed. Slip ratio of driving wheels on each side of vehicle are controlled separately or symmetrically through combined control of throttle and brake at different vehicle reference speed, and the fuzzy PID algorithm is built accordingly. The algorithm is validated by software in the loop simulation.
