The embodiment of the invention provides a vehicle emergency braking control method and device, a vehicle and a storage medium, and the method comprises the steps that when an emergency braking instruction is received, a service braking system is controlled to execute vehicle deceleration operation, and a motor in a parking braking system is controlled to forwards push a braking piston to move from an initial releasing position to a pre-tightening position; obtaining the current braking deceleration of the vehicle after the service braking system executes the vehicle deceleration operation; and according to the current braking deceleration, the pushing direction of the motor is controlled, so that emergency braking of the vehicle is achieved. By means of the method, when the service braking system is adopted for braking, the braking piston of the parking braking system is controlled to be located at the pre-clamping position, and under the condition that the deceleration of the vehicle is not expected, the parking braking system is combined to generate more braking force to conduct braking control; therefore, braking force can be generated more quickly, collision accidents are prevented, and the driving safety of a driver can be improved.

    本发明实施例提供了一种车辆紧急制动控制方法、装置、车辆及存储介质,该方法包括:当接收到紧急制动指令时,控制行车制动系统执行车辆减速操作且控制驻车制动系统中的电机正向推动制动活塞从初始释放位置移动至预加紧位置;获取行车制动系统执行车辆减速操作后车辆的当前制动减速度;根据当前制动减速度,控制电机的推动方向,以实现对车辆的紧急制动。利用该方法,在采用行车制动系统进行制动的同时,控制驻车制动系统的制动活塞处于预夹紧位置,在车辆的减速度不及预期的情况下,联合驻车制动系统产生更多制动力进行制动控制,由于制动活塞处于预夹紧位置,可以更快地产生制动力,防止碰撞事故发生,从而能够提高驾驶员的行驶安全性。
