The invention provides an energy recovery method and system of a hybrid electric vehicle and the vehicle. The method comprises the steps that the distance between a target vehicle and at least one activation source is collected; wherein the activation source is an object located in a preset range of the target vehicle in the sliding process of the target vehicle; according to the distance corresponding to each activation source, determining a target activation source and a target distance corresponding to the target activation source from each activation source; determining a target vehicle speed of the target vehicle and a safe distance between the target vehicle and the target activation source according to the target activation source; determining recovery target acceleration according to the target activation source, the target distance, the target vehicle speed and the safety distance; target vehicle information of the target vehicle is obtained, and the energy recovery torque of the target vehicle is calculated according to the recovery target acceleration and the target vehicle information; and controlling the target vehicle to recover energy according to the energy recovery torque.

    本发明提供一种混动汽车的能量回收方法、系统及车辆,采集目标车辆与至少一个激活源之间的距离;其中,激活源为在目标车辆滑行过程中,位于目标车辆预设范围内的物体;根据各个激活源对应的距离,从各个激活源中确定出目标激活源及其对应的目标距离;根据目标激活源确定目标车辆的目标车速和目标车辆与目标激活源的安全距离;根据目标激活源、目标距离、目标车速和安全距离,确定回收目标加速度;获取目标车辆的目标车辆信息,并根据回收目标加速度和目标车辆信息,计算目标车辆的能量回收扭矩;控制目标车辆根据能量回收扭矩进行能量回收。
