The invention relates to the technical field of hybrid power or electric automobiles, in particular to a control method and device for sliding energy recovery, a vehicle and a storage medium. The method comprises the steps that the driving shaft speed and the driven shaft speed are detected, the driving shaft slip rate is calculated, and the current working condition is recognized; searching a torque control threshold corresponding to the driven shaft speed, and comparing the slip rate of the driving shaft with the torque control threshold; if the slip rate of the driving shaft is larger than or equal to the torque control threshold and the current working condition is the pre-calibrated working condition, the torque control function is adjusted to be in a forbidden state; and obtaining a pre-calibrated delay duration, and adjusting the torque control function to an available state when the duration of the forbidden state reaches the delay duration. According to the embodiment of the invention, when the slip rate of the driving shaft is greater than or equal to the torque control threshold and is in the pre-calibrated working condition, the torque control function is adjusted to be in the forbidden state, the problem of forward rushing of the vehicle is avoided, and the stability of the vehicle during sliding energy recovery is improved.

    本申请涉及混合动力或电动汽车技术领域,特别涉及一种滑行能量回收的控制方法、装置、车辆及存储介质,方法包括检测驱动轴速和从动轴速,计算驱动轴滑移率并识别当前工况;查找与从动轴速相对应的扭矩控制门限,并将驱动轴滑移率与扭矩控制门限进行比对;若驱动轴滑移率大于或等于扭矩控制门限,且当前工况为预标定工况,则将扭矩控制功能调整为禁用状态;获取预先标定的延时时长,当禁用状态持续时间达到延时时长时,将扭矩控制功能调整为可用状态。本申请实施例在驱动轴滑移率大于或等于扭矩控制门限且为预标定工况时,将扭矩控制功能调整为禁用状态,避免车辆前冲问题,提高了车辆在滑行能量回收时的稳定性。
