The invention discloses an uphill auxiliary control method and system for an electric automobile, a storage medium and the electric automobile, and the method comprises the steps: when the speed of the automobile is lower than a preset calibration value and lasts for at least preset time, monitoring the boundary condition of the whole automobile; judging whether the whole vehicle boundary condition meets the whole vehicle boundary condition requirement or not; if yes, judging an upslope auxiliary boundary condition, and judging whether the upslope auxiliary boundary condition meets the upslope auxiliary boundary condition requirement or not; if yes, the torque value of the uphill auxiliary torque needed by the vehicle at the current gradient is calculated, and the uphill auxiliary torque is output to control a power motor of the whole vehicle to move; judging whether the uphill auxiliary boundary condition meets an uphill auxiliary function exit condition or not; if yes, the power motor is controlled to stop outputting the uphill assisting torque, and uphill assisting of the vehicle is completed. The problem that in the prior art, the uphill assisting function of electric automobile movement can only be used in a short time, and the requirement for multiple times of uphill assisting cannot be met is solved.

    本发明公开了一种电动汽车上坡辅助控制方法、系统、存储介质及电动汽车,该方法包括:当车辆的车速低于预设的标定值,且持续至少预设时间,对车辆的整车边界条件进行监控;判断整车边界条件是否满足整车边界条件要求;若是,对上坡辅助边界条件进行判断,判断上坡辅助边界条件是否满足上坡辅助边界条件要求;若是,计算车辆在当前坡度所需的上坡辅助扭矩的扭矩值,输出上坡辅助扭矩以控制整车的动力电机进行运动;判断上坡辅助边界条件是否满足上坡辅助功能退出条件;若是,控制动力电机停止输出上坡辅助扭矩,则车辆的上坡辅助完成。旨在解决现有技术中电动汽车运动的上坡辅助功能只能在短时间内使用,无法满足多次上坡辅助的需求的问题。
