A method for the improvement of the regulating performance of an anti blocking system -

摘要

The purpose of the invention is to improve the control characteristics of an antilocking system (ABS), in particular in the event of a sharp reduction in wheel contact force following passage over a bump in the road or similar disturbance in the road surface. During an ABS control cycle following partial braking, if the brake slip exceeds a predetermined limit and lasts longer than a predetermined minimum period, a product (P1,2) is calculated from the maximum brake slip and the period ( DELTA t) from the commencement (t1) of instability until the wheel reversal point (t2). If the product (P1,2) exceeds a predetermined limit (Pgrenz), the brake pressure on the affected wheel is allowed to build up again during the subsequent stable control phase with a steeper gradient by comparison with a normal control cycle.
