The invention discloses a slope parking start-stop control method and device of a vehicle, the vehicle and a storage medium. The hill-holding start-stop control method comprises the steps that when it is detected that a vehicle meets a half-slope parking condition, zero-rotation-speed control is conducted on a motor of the vehicle, and when the running speed of the vehicle is reduced to the zero speed, the current hill-holding torque value of the vehicle is obtained; when it is detected that the vehicle meets the hill starting condition, the stepping depth of an accelerator pedal of the vehicle is obtained in real time, and an expected motor torque value matched with the stepping depth of the accelerator pedal is obtained; and when the expected motor torque value is larger than the hill-holding torque value, the expected motor torque value is used for conducting torque control on a motor of the vehicle, so that one-time hill-holding start-stop control over the vehicle is completed. According to the technical scheme, the user operation experience can be improved, and the problem of small-amplitude reverse sliding at the moment of hill starting is solved. Half-slope hill-holding operation is easier, and half-slope hill-holding operation can advance and retreat and is safer and more reliable.

    本发明公开了一种车辆的驻坡启停控制方法、装置、车辆及存储介质。所述驻坡启停控制方法在检测到车辆满足半坡停车条件时,对所述车辆的电机进行零转速控制,并在所述车辆的运行速度降至零车速时,获取所述车辆当前的驻坡转矩值;在检测到所述车辆满足半坡起步条件时,实时获取所述车辆的油门踏板踩踏深度,并获取与所述油门踏板踩踏深度匹配的期望电机转矩值;在所述期望电机转矩值大于所述驻坡转矩值时,使用所述期望电机转矩值对所述车辆的电机进行转矩控制,以完成对所述车辆的一次驻坡启停控制。本发明实施例的技术方案能够提高用户操作体验,解决半坡起步瞬间小幅度倒溜的问题。使半坡驻坡操作更加简易,半坡可进可退,更加安全可靠。
