Abstract :
In this paper, a traction control algorithm based on fuzzy PID and modulation of pump based on PWM is proposed. The target brake pressure needed to be exerted on the driving wheel is determined by a fuzzy PID controller from the difference between the target wheel speeds and actual wheel speeds and is fulfilled by PWM control of hydraulic pump of the hydraulic control unit. The control algorithm is validated based on a hardware Hardware-in-the-loop (HIL) test bench which is based on the xPC Target™ product of MATLAB®, and the test results of show that the algorithm can control the spin of driven wheels effectively.
