The embodiment of the invention provides a hybrid power vehicle energy optimization method and system, a storage medium and electronic equipment. The method comprises the following steps: determining a wheel side required torque according to a vehicle speed and a vehicle driving working condition; when the wheel side required torque is positive, the engine rotating speed is determined according to the vehicle speed and the engine speed ratio; judging whether an engine starting condition is met or not according to the engine speed; and if the starting condition of the engine is met, the fuel consumption of the vehicle is minimized by optimizing the torque of the engine and the torque of the motor. According to the method, the problems of engine faults such as knocking and fire due to optimization of the compression ratio of the engine, improvement of an oil supply and ignition system and reduction of the fuel consumption rate of the vehicle can be avoided, limiting factors of the electric quantity of the whole vehicle battery are considered, and the service life of the battery can be prolonged.
本发明实施例提供了一种混合动力车辆能量优化方法、系统、存储介质及电子设备。其中,方法包括:根据车速和车辆行驶工况确定轮边需求扭矩;在轮边需求扭矩为正时,根据车速和发动机速比确定发动机转速;根据发动机转速判断是否达到发动机启动条件;若达到发动机启动条件,则通过优化发动机转矩和电机转矩的方式使车辆燃油消耗最低。本发明能够避免因优化发动机压缩比、改善供油和点火系统降低车辆燃油消耗率出现爆震、失火等发动机故障的问题,并且考虑了整车电池电量的限制因素,能够增加电池的使用寿命。
