The invention belongs to the technical field of vehicle control, and discloses a vehicle automatic parking method, device and equipment and a storage medium. The method comprises the following steps: when a vehicle arrives at a traffic light intersection and receives an automatic parking instruction, obtaining a current vehicle distance; when the current vehicle distance is in the parking braking interval, target deceleration is determined according to the current vehicle distance and the current vehicle speed; the target deceleration is converted into target negative torque, and the vehicle is controlled to decelerate through the target negative torque; and when the vehicle slows down to the target vehicle speed, the brake calipers are controlled to be pulled up to complete automatic parking. Through the mode, after a user triggers an automatic parking instruction, the required deceleration is automatically calculated according to the current vehicle speed and the vehicle distance, and then the motor is automatically controlled to brake, so that automatic braking and automatic parking at a traffic light intersection are automatically realized under the condition that a driver does not need to operate; the accident occurrence probability of the traffic light intersection is reduced, and the driving safety is improved.

    本发明属于车辆控制技术领域,公开了一种车辆自动驻车方法、装置、设备及存储介质。该方法包括:当车辆到达红绿灯路口并接收到自动停车指令时,获取当前车距;当所述当前车距处于停车制动区间时,根据所述当前车距和当前车速确定目标减速度;将所述目标减速度转化为目标负扭矩,并通过所述目标负扭矩控制车辆减速;当车辆减速到目标车速时,控制制动卡钳拉起,以完成自动驻车。通过上述方式,实现了在用户触发自动停车的指令后,自动根据当前车速和车距计算需要的减速度,然后自动控制电机制动,使得不需要驾驶员操作的情况下自动实现在红绿灯路口的自动刹车和自动驻车,减少了红绿灯路口的事故发生概率,提高了行车安全性。
