Comparison of the improvement of directional stability for Anti-lock Brake control algorithm

Abstract

A nine freedoms nonlinear three-axle vehicle dynamic model was constructed by Matlab/Simulink to analyze the control effect of directional stability for different Anti-lock Brake control algorithm. Algorithms analyzed here contain PID, logic threshold and sliding mode variable structure control algorithm. Then comparing and analyzing the control effect from the aspects of tire/whole vehicle parameters and the phase-plane of slid slip rate and its rate.
