The invention discloses a hybrid electric vehicle sliding energy recovery torque control method. The whole vehicle control unit judges the activation condition of the sliding energy recovery torque calculation when the vehicle is in the sliding state; the whole vehicle control unit determines whether to activate the sliding energy recovery torque calculation or not according to the key switch state, the handle position, the accelerator pedal opening degree, the brake pedal opening degree and the sliding energy feedback forbidding function request input signal; s2, a sliding energy recovery torque factor is calculated, specifically, the vehicle control unit determines the sliding energy recovery torque factor in the sliding state according to a fuzzy control system; and S3, the sliding energy recovery torque is obtained, specifically, the whole vehicle control unit obtains the sliding energy recovery torque by looking up a sliding energy recovery torque two-dimensional table according to the sliding energy recovery torque factor and the set sliding energy feedback intensity grade.
一种混合动力汽车滑行能量回收扭矩控制方法,包括如下步骤:S1,整车控制单元判断车辆处于滑行状态下的滑行能量回收扭矩计算的激活条件:整车控制单元根据钥匙开关状态、手柄位置、油门踏板开度、制动踏板开度、禁止滑行能量回馈功能请求输入信号确定是否激活滑行能量回收扭矩计算;S2,滑行能量回收扭矩因子计算:整车控制单元根据模糊控制系统确定滑行状态下的滑行能量回收扭矩因子;S3,得到滑行能量回收扭矩:整车控制单元根据滑行能量回收扭矩因子和设置的滑行能量回馈强度等级通过查滑行能量回收扭矩二维表得到滑行能量回收扭矩。
