The invention provides a sliding energy recovery control method and system and a vehicle, and belongs to the technical field of energy recovery. The method comprises the following steps that the current slip rate of a vehicle in a sliding state is obtained; when the current slip rate is larger than a preset value, the ABS function of the vehicle is activated, and recovery torque is adjusted to preset recovery torque; the current slip rate continues to be obtained, and when the current slip rate is larger than a preset value, the recovery torque is adjusted to second recovery torque from the preset recovery torque; after the current slip rate is smaller than a preset value, the recovery torque is adjusted from the second recovery torque to the first recovery torque, and whether a torque recovery request is smaller than an energy recovery request or not is judged; and when the torque recovery request is smaller than the energy recovery request, the steps are repeated. The problems that in the prior art, pause is generated when the sliding energy of the vehicle is recycled, so that the vehicle slides unsmoothly, and uncomfortable feeling is brought to a driver are solved.

    本发明提供了一种滑行能量回收的控制方法、系统及车辆,属于能量回收技术领域。该方法包括以下步骤:获取滑行状态中的车辆的当前滑移率;在所述当前滑移率大于预设值时,激活所述车辆的ABS功能并将回收扭矩调节至预设回收扭矩;继续获取所述当前滑移率,在所述当前滑移率大于预设值时,将所述回收扭矩从所述预设回收扭矩调节至第二回收扭矩;在所述当前滑移率小于预设值后,将所述回收扭矩由所述第二回收扭矩调节至第一回收扭矩并判断扭矩回收请求是否小于能量回收请求;在所述扭矩回收请求小于能量回收请求时,则重复上述步骤。本发明解决了现有技术中车辆在滑行能量回收时产生顿挫,使得车辆滑行不平顺,给驾驶者带来不舒适感受的问题。
