Abstract: The effects of a road vehicle|s front and rear wheel slips on its stability and stopping ability under different conditions are studied. A simple in-plane model of a road vehicle is employed. The vehicle parameters used for simulation are those of a commercial vehicle. Two road conditions have been considered. During a given braking manoeuvre front and rear wheel slips are kept constant. From the results of digital simulation it is observed that even when both front and rear wheels are locked the vehicle will become unstable when there is a yaw angle disturbance at the beginning of a braking manoeuvre. Optimum slip ranges are determined for various road and speed conditions.

Keywords: vehicle design; wheel slip; braking control; vehicle dynamics; dynamic behaviour; mathematical modelling; road vehicles; digital simulation.
