The invention discloses a vehicle anti-lock braking system, a control method of the vehicle anti-lock braking system and a vehicle. The control method comprises the steps that road adhesion coefficients of the left side and the right side of the vehicle are obtained, and the current wheel speed of wheels of a first rear axle connected with a first rear axle and the current wheel speed of wheels of a second rear axle connected with a second rear axle are obtained; according to the current wheel speed of the first rear axle wheel, the slip rate of the first rear axle wheel is obtained, and according to the current wheel speed of the second rear axle wheel, the slip rate of the second rear axle wheel is obtained; and according to the road adhesion coefficient, the slip rate of the first rear axle wheel and the slip rate of the second rear axle wheel, anti-lock actuators of the rear axle left side brake channel and the rear axle right side brake channel are controlled respectively. By the adoption of the method, the rear axle wheels can be prevented from being locked when the vehicle is braked emergently, braking drifting caused by the influence of adhesive force is avoided, the maneuverability and transverse stability of the vehicle are improved, and the risk that the vehicle is out of control is reduced.
本发明公开了一种车辆防抱死制动系统及其控制方法和车辆,所述控制方法包括:控制方法包括:获取车辆左右两侧的路面附着系数以及获取所述后一桥所连接的后一桥车轮的当前轮速和所述后二桥所连接的后二桥车轮的当前轮速;根据所述后一桥车轮的当前轮速获得所述后一桥车轮的滑移率以及根据所述后二桥车轮的当前轮速获得所述后二桥车轮的滑移率;根据所述路面附着系数、所述后一桥车轮的滑移率和所述后二桥车轮的滑移率分别控制所述后桥左侧制动通道和所述后桥右侧制动通道的防抱死执行器。采用该方法可以在车辆进行紧急制动时防止后桥车轮发生抱死,且不会受附着力影响而发生制动甩尾,提高了车辆的可操纵性和横向稳定性,降低了车辆失控的风险。
