The invention discloses a ramp parking control method, device and equipment and a storage medium, and the method comprises the steps that a vehicle drives into a ramp, and a parking control instruction is received; when it is determined that the vehicle meets the parking condition, the parking control instruction is sent to the control module; and the locking signal returned by the control module is received, and the first torque output by the driving motor is cancelled. Therefore, when the vehicle is driven into the ramp and the vehicle locking signal is determined to be received, the vehicle is locked, that is, the vehicle stably stays on the ramp, the torque output by the driving motor is cancelled, and the vehicle is prevented from sliding on the ramp. For example, the parking control instruction is a P-gear engaging instruction, torque is cancelled only when a vehicle locking signal is received, the NVH problem caused by knocking of a pawl and a ratchet wheel during P-gear engaging is avoided, or the situation that the vehicle slides on a slope when the pawl cannot be clamped into the ratchet wheel is avoided; the parking control instruction is an instruction generated when the electronic parking is started, the torque is cancelled only when the vehicle locking signal is received, and slope sliding and pause when locking of the electronic parking is not completed are avoided.

    本申请公开一种坡道驻车控制方法、装置、设备及存储介质,该方法包括:车辆驶入坡道,接收到驻车控制指令;确定车辆满足驻车条件,将驻车控制指令发送至控制模块;接收到控制模块返回的锁止信号,撤销驱动电机输出的第一扭矩。如此,车辆驶入坡道,确定接收到车辆锁止信号,表明车辆锁止,即车辆稳定停留在坡道,此时撤销驱动电机输出的扭矩,避免车辆溜坡。例如,驻车控制指令为P挡挂入指令,接收到车辆锁止信号才撤销扭矩,避免P挡挂入时棘爪与棘轮发生敲击产生NVH问题,或者避免棘爪无法卡入棘轮时发生车辆溜坡;驻车控制指令为电子驻车启动时产生的指令,接收到车辆锁止信号才撤销扭矩,避免电子驻车未完成锁止时发生溜坡以及顿挫。
