The invention discloses a vehicle anti-lock braking system, a control method of the vehicle anti-lock braking system and a vehicle. The vehicle comprises a front axle and a rear axle, the front axle comprises a first front axle body and a second front axle body, the vehicle anti-lock braking system comprises a front axle left side braking channel and a front axle right side braking channel, and the vehicle anti-lock braking system is used for conducting anti-lock braking adjustment on wheels. Road adhesion coefficients of the left side and the right side of the vehicle are obtained, and the current wheel speed of wheels of the first axle connected with the previous axle and the current wheel speed of wheels of the second axle connected with the previous second axle are obtained; the slip rate of the first-axle wheels is obtained according to the current wheel speed of the first-axle wheels, and the slip rate of the second-axle wheels is obtained according to the current wheel speed of the second-axle wheels; according to the road adhesion coefficient, the slip rate of the first-axle wheels and the slip rate of the second-axle wheels, anti-lock actuators of the front-axle left-side braking channel and the front-axle right-side braking channel are controlled correspondingly, and the situation that the wheels are locked and deviated during emergency braking of the vehicle is avoided.
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。其中,车辆包括前桥和后桥,前桥包括前一桥和前二桥,车辆防抱死制动系统包括前桥左侧制动通道和前桥右侧制动通道,用于对车轮进行防抱死制动调节,其控制方法包括:响应于制动信号并且车速大于零,获取车辆左右两侧的路面附着系数以及获取前一桥所连接的一桥车轮的当前轮速和前二桥所连接的二桥车轮的当前轮速;根据一桥车轮的当前轮速获得一桥车轮的滑移率以及根据二桥车轮的当前轮速获得二桥车轮的滑移率;根据路面附着系数、一桥车轮的滑移率和二桥车轮的滑移率分别控制前桥左侧制动通道和前桥右侧制动通道的防抱死执行器,避免车辆在紧急制动时,车轮出现抱死和制动跑偏的情况。
