The invention belongs to the hybrid electric vehicle energy management technology, and particularly relates to a hybrid electric vehicle energy control method which is simple in control and easy to implement, and mode division and rule making are performed on the working state of a motor or an engine according to different torques, vehicle speeds and SOC conditions (such as accelerator pedal and brake pedal instructions) or efficiency Map maps and the like. By adjusting the output power of a test cycle engine, the working point (torque rotating speed) of the engine is determined, so that the state of charge (SOC) of the battery before and after the cycle working condition is balanced. Not only can the requirements of fuel consumption regulations be met, but also a good final fuel consumption result can be achieved.
本发明属于混合动力汽车能量管理技术,具体涉及一种混动汽车能量控制方法,其控制简单,易于实现,根据不同的扭矩、车速与SOC条件(如油门踏板、制动踏板指令)或其效率Map图等,对电机或发动机工作状态进行模式划分,制定规则进行控制。通过调整试验循环发动机输出功率,确定发动机工作点(扭矩转速),使得循环工况前后电池荷电状态(State of Charge,SOC)平衡。既能满足油耗法规规范要求,也能做到良好的油耗最终结果。
