The embodiment of the invention provides a vehicle hill starting control method and device, a readable storage medium and a vehicle. The method comprises the steps that when the gradient of a road is larger than a preset gradient, the state of a brake valve of the vehicle is detected; when it is detected that the brake valve is in the brake state, the voltage value corresponding to the brake air pressure of the brake valve is obtained in real time; when it is detected that the voltage value is reduced to the first preset voltage value, pre-output torque is determined for a motor of the vehicle, and the motor of the vehicle is controlled to establish the pre-output torque; and under the condition that it is detected that the voltage value is reduced to the second preset voltage value, a motor of the vehicle is controlled to output pre-output torque so as to provide driving force for the vehicle. According to the method provided by the embodiment of the invention, the possible starting behavior of the vehicle on the ramp is detected, and the torque establishment of the vehicle motor is completed in time before the brake valve cannot provide enough braking force, so that the vehicle is effectively prevented from sliding on the ramp, and the safety performance of the vehicle is improved.

    本申请实施例提供了一种车辆坡道起步控制方法、装置、可读存储介质和车辆,所述方法包括:在道路的坡度大于预设坡度时,对车辆的制动阀的状态进行检测;在检测到制动阀处于刹车状态时,实时获取制动阀的制动气压对应的电压值;在检测到电压值降低到第一预设电压值的情况下,为车辆的电机确定预输出扭矩,控制车辆的电机建立预输出扭矩;在检测到电压值降低到第二预设电压值的情况下,控制车辆的电机输出预输出扭矩,以为所述车辆提供驱动力。本申请实施例提供的方法,针对车辆在坡道上的可能存在的启动行为进行检测,在制动阀不能提供足够制动力之前,及时完成车辆电机的扭矩建立,有效防止车辆溜坡,提高车辆安全性能。
