The invention belongs to the field of automobile control, and particularly relates to a vehicle braking deviation control method. In order to solve the problem of deviation generated in the braking process, the braking deviation compensation function is achieved through a software strategy and an algorithm mode of an EPS (electric power steering) system. The method does not need to increase the cost of the whole vehicle, and carries out strategy development according to the basic standard configuration of the existing vehicle; aiming at a wheel speed difference value caused by a braking force difference of four wheels of a front axle and a rear axle when the four wheels of an actual vehicle are braked, steering compensation is performed through electric power-assisted steering, so that braking deviation steering power-assisted compensation is realized.

    本发明属于汽车控制领域,具体涉及一种车辆制动跑偏的控制方法。本发明针对制动过程中产生的跑偏问题,通过电动助力转向系统EPS(electrical power steering system)软件策略、算法方式实现制动跑偏补偿功能。本发明无需增加整车成本,根据现有车辆基本标配的配置进行策略开发;针对实际车辆四轮制动时,前后轴四轮制动力差异导致的轮速差值,通过电动转向助力进行转向补偿,以起到制动跑偏转向助力补偿。
