The invention relates to the technical field of new energy automobiles, in particular to an uphill auxiliary function exit method and device, a vehicle and a storage medium, and the method comprises the steps that the on-off state of an uphill auxiliary function of the vehicle is recognized; when it is recognized that the switch state is a closed state, it is judged that the uphill auxiliary function exits, and the hand brake state, the current gear and the actual gradient value of the vehicle are obtained; and according to the hand brake state, the current gear and/or the actual slope value, matching the hill-holding exit gradient of the vehicle, and controlling a driving motor of the vehicle to output torque according to the hill-holding exit gradient so as to maintain the vehicle in a preset stable state when the uphill auxiliary function exits. Therefore, the problems that when the uphill auxiliary function achieved in a motor stalling mode exits in the related technology, the torque of motor stalling suddenly disappears, the whole vehicle shakes and impacts, and the user experience is poor are solved.
本申请涉及新能源汽车技术领域,特别涉及一种上坡辅助功能退出方法、装置、车辆及存储介质,其中,方法包括:识别车辆的上坡辅助功能的开关状态;在识别到开关状态为关闭状态时,判定上坡辅助功能退出,并获取车辆的手刹状态、当前挡位和实际坡度值;根据手刹状态、当前挡位和/或实际坡度值匹配车辆的驻坡退出梯度,控制车辆的驱动电机按照驻坡退出梯度输出扭矩,以在上坡辅助功能退出时维持车辆处于预设平稳状态。由此,解决了相关技术中采用电机堵转方式实现的上坡辅助功能退出时,电机堵转的转矩突然消失,使得整车出现抖动和冲击现象,用户体验不佳等问题。
