ABSTRACT
Studies were made on the effects of braking force distribution, on a vehicle’s lateral and longitudinal directions. The studies were made on distribution on non-linear regions, under combined high lateral acceleration and deceleration conditions, using the value of the yaw moment versus the side slipangle. Consequently, a method for obtaining optimum braking force distribution was found.
Controlling the lateral distribution of the braking force on the front wheels was found to be effective for the improvement of vehicle stability, while that on the rear wheels was found to be effective for extending the limit of vehicle motion. Therefore, controlling the lateral distribution of the braking force on both the front and rear wheels achieves the two effects mentioned above. Simulation tests were carried out to confirm these effects in terms of turning performance and controllability to avoiding obstacles in emergency situations.
