Method of enhancing the reliablity in operation of a brake system with electronic control of the brake force distribution

摘要

To enhance the reliability of a brake system with electronic control of the brake force distribution, a short pressure reduction pulse, which is negligible for the braking process, is applied to the front wheels (VR, VL) during a braking operation, and the reaction of the front wheels to the pressure reduction pulse is sensed. If imbalance of the front-wheel brakes or a defect is concluded from the reaction, the limitation of the pressure rise in the wheel brakes of the rear wheels (HR, HL), which is an effect of the brake force distribution control, is minimized or eliminated. Thus, the rear wheels provide an increased contribution to the braking process in this situation.
