The invention discloses a cross-country electric vehicle in-situ starting crawling torque control method, which comprises the following specific steps of: sequentially judging whether a vehicle meets the requirements of engaging a D gear and not engaging an R gear or not and whether the change rate of the electric control opening corresponding to a brake pedal and the change rate of the electric control opening corresponding to a loose brake pedal meet a set threshold range or not; if yes, the torque control device is closed, and otherwise, S20 is executed; s30, whether the downward gradient of the vehicle in the forward direction meets a set gradient threshold range or not and whether the vehicle speed is smaller than a speed threshold value or not are sequentially judged, if at least one of the two conditions is not met, the torque control device is turned off, and if not, the step S30 is executed; the torque control device is started, the crawling torque is adjusted according to the vehicle speed, the acceleration and the gradient, and the step S10 is executed again; the invention further discloses a corresponding device, a storage medium and a vehicle. Smooth transition and accurate adjustment of the torque are achieved, and the driving requirements of a driver on different road conditions are met.

    本发明公开了越野电动车原地起步爬行扭矩控制方法,具体步骤为:依次判断车辆是否满足挂D档、没有挂R档及刹车踏板对应电控开度及松制动踏板对应电控开度变化速率是否满足设定阈值范围,如果三个条件中至少有一个不满足,则关闭扭矩控制装置,否则进入S20;依次判断车辆前进方向向下坡度是否满足设定的坡度阈值范围及车辆速度是否小于速度阈值,如果两个条件中至少有一个不满足,则关闭扭矩控制装置,否则进入S30;开启扭矩控制装置,根据车辆速度、加速度及坡度调整爬行扭矩,并再次进入S10;还公开了对应装置、存储介质及车辆;实现扭矩的平滑过渡和精确调节,满足驾驶员不同路况的驾驶需求。
