The invention provides a vehicle braking control method, a controller and a vehicle, and the vehicle braking control method comprises the following steps: in response to an emergency braking request of the vehicle, controlling a braking caliper of the vehicle to increase a caliper braking torque according to a first rate threshold value, and controlling a motor of the vehicle to increase a regenerative braking torque according to a second rate threshold value, and the wheels of the vehicle are braked. According to the method, during emergency braking, the braking capacity of the motor and the braking calipers is utilized, the braking torque is output to the wheel end through the motor and the braking calipers at the same time through cooperative control in the establishing stage of the braking strength, the purpose of increasing the vehicle braking loading rate is achieved, and therefore the coordination time during emergency braking of the vehicle can be shortened; the vehicle braking distance during emergency braking is shortened, and the braking performance of the vehicle is improved.

    本发明提出了一种车辆制动控制方法、控制器及车辆,其中车辆制动控制方法包括:响应于车辆的紧急制动请求,控制车辆的制动卡钳按照第一速率阈值增大卡钳制动力矩,控制车辆的电机按照第二速率阈值增大再生制动力矩,以对车辆的车轮进行制动。该方法在紧急制动时,利用了电机和制动卡钳的制动能力,在制动强度的建立阶段通过协同控制,通过电机和制动卡钳同时向车轮端输出制动力矩,达到增加车辆制动加载速率的目的,从而可以减少车辆紧急制动时的协调时间,缩短紧急制动时的车辆制动距离,提升车辆的制动性能。
