The invention relates to an automobile single-pedal sliding control method, device and equipment and a storage medium, the method comprises the steps that the vehicle state is obtained, the vehicle state at least comprises an accelerator pedal opening value, and the accelerator pedal opening change rate is obtained according to the accelerator pedal opening value; according to the accelerator pedal opening degree change rate, whether a torque compensation condition is met or not is determined, and when the torque compensation condition is met, a compensation torque initial value is determined and kept; and according to the compensation torque initial value, initial demand negative torque during single-pedal sliding is subjected to forward compensation, so that the whole vehicle demand torque at the beginning of sliding is reduced, and when the difference between the whole vehicle actual torque and the whole vehicle demand torque is smaller than a torque threshold value, the compensation torque initial value is reduced in a gradient mode, so that the whole vehicle demand torque is reduced. By the adoption of the method, the problem that in the prior art, the initial energy recovery strength is too high in a single-pedal mode can be solved.

    本申请涉及一种汽车单踏板滑行控制方法、装置、设备和存储介质,所述方法包括获取车辆状态,所述车辆状态至少包括加速踏板开度值,并根据所述加速踏板开度值获得加速踏板开度变化率;根据所述加速踏板开度变化率确定扭矩补偿条件是否满足,当所述扭矩补偿条件满足时,确定补偿扭矩初始值并保持;根据所述补偿扭矩初始值对单踏板滑行时的初始需求负扭矩进行前向补偿,以使得滑行起始的整车需求扭矩减小,当所述整车实际扭矩与所述整车需求扭矩的之差小于扭矩阈值时,梯度降低所述补偿扭矩初始值,以使得所述整车需求扭矩等于初始需求负扭矩,采用本申请方法,可以改善现有技术中单踏板模式下能量回收强度起始过大的问题。
