The invention relates to a vehicle driving technology, in particular to a method for torque distribution of a power system of a hybrid vehicle, a vehicle controller implementing the method and a computer readable storage medium. The method for torque distribution of a powertrain of a hybrid vehicle according to one aspect of the present invention comprises the steps of: A) offline analyzing enginefuel efficiency characteristic data to obtain an engine efficiency optimal interval; and B) determining a driving mode of the vehicle by monitoring the battery power state on line in real time in therunning process of the vehicle, wherein the driving mode comprises a pure electric driving mode and a hybrid power driving mode. And when it is determined that the driving mode of the vehicle entersthe hybrid power driving mode, an engine working point is adjusted in real time according to the position, corresponding to the engine efficiency optimal interval, of the torque required by the user so that the actual working torque of the engine can fall into the engine efficiency optimal interval as much as possible.

    本发明涉及车辆驱动技术,具体涉及用于混合动力车辆的动力系统的扭矩分配的方法、实现该方法的车辆控制器和计算机可读存储介质。按照本发明一个方面的用于混合动力车辆的动力系统的扭矩分配的方法包含下列步骤:A)离线分析发动机燃油效率特性数据以获得发动机效率最优区间;B)在车辆行驶过程中通过在线实时监控电池电量状态来确定车辆的驱动模式,其中所述驱动模式包括纯电动驱动模式和混合动力驱动模式。当确定所述车辆的驱动模式进入混合动力驱动模式时,根据用户需求扭矩对应于所述发动机效率最优区间的位置,实时调节发动机工作点以使得所述发动机的实际工作扭矩尽可能地落在所述发动机效率最优区间。
