The invention discloses a hybrid electric vehicle energy management system based on driving intention recognition. A driving intention recognition system judges whether a driving style belongs to a power mode or an economic mode according to a vehicle average acceleration and an acceleration mean variance; judging whether the acceleration state of the driver is general acceleration, gentle acceleration or emergency acceleration according to the accelerator pedal opening degree and the pedal opening degree change rate; judging whether the starting intention or the cruising speed is a low speed, a medium speed or a high speed by combining the vehicle speed with the vehicle acceleration; the working mode selection system determines a main power source according to driving intention judgment made by the driving intention recognition system and in combination with an SOC value; meanwhile, the torque optimization distribution system carries out power distribution; the method is combined with a control strategy proposed for the multimode coupling driving system, a corresponding energy management strategy is formulated, and the fuel consumption of the multimode coupling driving system is reduced.
本发明公开了一种基于驾驶意图识别的混合动力汽车能量管理系统,所述驱动意图识别系统以车辆平均加速度、加速度均值方差来判断驾驶风格属于动力模式还是经济模式;以加速踏板开度、踏板开度变化率判断驾驶员加速状态为一般加速、平缓加速还是紧急加速;以车辆速度结合车辆加速度来判断起步意图或巡航速度为低速、中速还是高速;所述工作模式选择系统根据驱动意图识别系统做出的驾驶意图判断,再结合SOC值确定主要动力源;同时,所述转矩优化分配系统进行动力分配;本发明将其与针对多模耦合驱动系统提出的控制策略相结合,制定出相应的能量管理策略,降低多模耦合驱动系统的燃油消耗。
