The invention discloses a new energy automobile sliding energy recovery intensity calculation method which comprises the following steps: S1, in a whole automobile energy recovery control state, a whole automobile enters energy recovery control, and a motor starts to convert the kinetic energy and potential energy of the whole automobile into electric energy through energy recovery control and stores the electric energy into a battery pack; s2, whether the whole vehicle enters sliding energy recovery control or not is judged, whether the whole vehicle enters sliding energy recovery control or not is judged, and a whole vehicle control unit determines whether sliding energy recovery enters or not by monitoring the key switch state, the handle position, the accelerator pedal opening degree, the brake pedal state, the sliding energy recovery forbidding request and the like; s3, in a sliding energy recovery intensity fuzzy control state, the sliding energy recovery intensity is subjected to optimization control through a fuzzy control method for adjusting the energy recovery intensity based on the vehicle speed, the accelerator pedal opening degree change rate and the battery charging power; by means of the method, sliding energy recovery is controlled, and the sliding smoothness and fuel economy of the whole vehicle are improved.
本发明公开了一种新能源汽车滑行能量回收强度计算方法,S1,整车能量回收控制状态,整车进入能量回收控制,电机开始将整车动能及势能通过能量回收控制转化为电能,并存储至电池包中;S2,判断整车是否进入滑行能量回收控制,整车判断是否进入滑行能量回收控制,整车控制单元通过监控钥匙开关状态、手柄位置、油门踏板开度、刹车踏板状态,禁止滑行能量回收请求等确定是否进入滑行能量回收;S3,滑行能量回收强度模糊控制状态,基于整车车速、油门踏板开度变化率、电池充电功率调节能量回收强度的模糊控制方法,对滑行能量回收强度进行优化控制;通过本方法对滑行能量回收控制,提高整车的滑行平顺性和燃油经济性。
