Abstract:

An integrated control scheme of vehicle ABS and active suspension was proposed. Smooth sliding-mode control method for ABS and backstepping control method for active suspension were combined. The active suspension increases the vertical normal force on the wheel when the sliding rate of the wheel is at its best. Its objective is to minimize the stopping distance when the vehicle is braking. A vehicle model was built under the Matlab/Simulink software environment. The simulation results show that there exists an optimal application of the suspension force. Compared with an ABS system without combining active suspension, the integrated control scheme can improve braking performance significantly.

Key words: active suspension, anti-lock braking system(ABS), smooth sliding-mode control, backstepping control
