The invention provides an energy recovery method and system for a hybrid vehicle. The energy recovery method comprises the following steps: obtaining vehicle state information in the vehicle running process, wherein the vehicle state information comprises pedal approaching information and pedal opening degree information of an accelerator pedal and a brake pedal; judging driving intention of a driver according to the vehicle state information; and recovering energy of the vehicle in a sliding state and a braking state according to the driving intention of the driver and a multi-gear energy recovery strategy. According to the scheme, different working conditions can be distinguished; under the condition that deceleration is possibly needed, large reverse towing torque is implemented; underthe condition that sliding is possibly needed, small reverse towing torque is implemented; and under the condition that driving experience is not affected as much as possible, the energy recovery efficiency is improved.

    本发明提供了一种用于混合动力车辆的能量回收方法及系统。所述能量回收方法包括如下步骤:获取车辆行驶过程中的车辆状态信息,所述车辆状态信息包括加速踏板以及制动踏板的踏板接近信息以及踏板开度信息;根据所述辆状态信息判断驾驶员的驾驶意图;根据所述驾驶员的所述驾驶意图按照多挡位能量回收策略回收车辆在滑行状态和制动状态时的能量。本发明方案实现了可以区分不同的工况,在可能需要减速的情况下,实施较大的反拖扭矩,在可能需要滑行的情况下,实施较小的反拖扭矩,在尽量不影响驾驶体验的情况下,提高能量回收效率。
