The invention provides an electric vehicle control method and device, a storage medium and a vehicle control unit. The method comprises the steps that whether an electric vehicle enters a crawling mode or not is judged according to the current speed of the electric vehicle; if it is judged that the electric vehicle enters the crawling mode, the current brake pedal opening degree of the electric vehicle is obtained; determining a first crawling torque of the electric vehicle according to the vehicle speed and the opening degree of the brake pedal; and sending the first creep torque to a motor controller of the electric vehicle. According to the scheme provided by the invention, the motor output shaft gear and the transmission shaft gear can be kept in an engaged state all the time, so that the tooth breaking and shaking phenomena of the gears are weakened or eliminated.
本发明提供一种电动车辆控制方法、装置、存储介质和整车控制器,所述方法包括:根据所述电动车辆当前的车速判断是否进入蠕行模式;若判断进入蠕行模式,则获取所述电动车辆当前的制动踏板开度;根据所述车速和所述制动踏板开度确定所述电动车辆的第一蠕行扭矩;向所述电动车辆的电机控制器发送所述第一蠕行扭矩。本发明提供的方案能够使得电机输出轴齿轮与传动轴齿轮时刻保持啮合状态,从而减弱或消除齿轮打齿和抖动现象。
