Abstract:0.1965增為0.1981,。A coordination control method of vehicle active front wheel steering and ABS on steering and braking conditions was presented. At first, steering system controller and ABS controller were designed separately, and then an upper coordination controller was set up based on an idea of delaminating control in order to coordinate the two subsystems. The simulation results showed that: the vehicle had better steering stabilization and braking performance by applying this method to control the active front wheel steering and ABS, the root mean square value of vehicle raw rate decreased from 0.0461 rad/s to 0.0382 rad/s, the root mean square value of lateral acceleration decreased from 0.9352m/s2 to 0.7886m/s2, the brake distance decreased from 23.9845 m to 23.1092 m, the root mean square value of slip rate of front wheel increased from 0.1968 to 0.1975, and slip rate of rear wheel increased from 0.1965 to 0.1981.
