The invention relates to the field of automobile control, and provides a WLTC working condition economical efficiency optimization method and system for a plug-in hybrid vehicle, and aims to realize targeted adjustment of different scenes by performing real-time driving analysis on a current vehicle and performing driving mode setting more in line with an actual driving scene of a user. The problems that pure electric working conditions generated in an ultra-low-speed scene and a high-speed scene are too many, the motor assisting torque in the high-speed scene is limited, and an engine works outside an economic zone are solved, and when a user switches between different driving modes, targeted engine state adjustment is carried out, so that the user experience is improved. By means of the method, the WLTC working condition economical efficiency of the plug-in hybrid power vehicle is improved.

    本发明涉及汽车控制领域,提出了一种插电混动车型的WLTC工况经济性优化方法及系统,通过对当前车辆进行实时的驾驶分析,进行更符合用户实际驾驶场景的驾驶模式设置,实现了对不同场景的针对性调节,避免了在超低速场景和高速场景下产生的纯电工况过多,高速场景电机助力扭矩受限,发动机工作在经济区外的问题,又通过对用户在不同驾驶模式之间切换时,进行针对性的发动机状态调节,使得发动机持续工作在较高经济性的工作区间内,本发明提高了插电混动车型的WLTC工况经济性。
