In order to solve a technical problem that the existing energy recovery method cannot adaptively adjust the output power of a motor according to actual working conditions or intention of a driver, theinvention provides a self-adaptive energy recovery method of a pure electric vehicle. The method comprises the following steps: judging whether a vehicle signal meets the condition of braking energyrecovery or sliding energy recovery or not; adjusting a corresponding energy recovery strategy; and adaptively adjusting the torque output of the current energy recovery by adding parameters such as an energy recovery grade set by a driver and the like. According to the invention, while the energy recovery is increased and the energy consumption of the whole vehicle is reduced, the energy recoveryis combined with the actual working condition; the energy level is adjusted according to the intention of a driver, the requirement of the driver on the power of the whole vehicle is met; and the economy and power performance of the whole vehicle are considered.

    为解决现有能量回收方法无法根据实际工况或司机意图自适应调整电机输出功率的技术问题,本发明提供了一种纯电动汽车的自适应能量回收方法,通过判断整车信号是否满足制动能量回收或滑行能量回收的条件,进行相应的能量回收策略调整,并通过加入司机设定能量回收等级等参数,自适应的调整当前能量回收的扭矩输出。本发明在增加能量回收,降低整车能耗的同时,将能量回收与实际工况结合,按照司机意图进行能量等级的调整,满足司机对整车动力的要求,同时兼顾整车经济性与动力性。
