The invention discloses an engine crankshaft position adjusting method and device and a hybrid vehicle. The engine crankshaft position adjusting method comprises the steps that it is judged that a vehicle enters a stopping process; and controlling the clutch to close according to the judgment result. Position information of a crankshaft of an engine is obtained. And according to the position information of the crankshaft of the engine, the clutch is controlled to be disconnected, so that the crankshaft of the engine reaches the crankshaft target position. According to the technical scheme, the compensation torque value of the motor can be reduced, and the accuracy of engine crankshaft position adjustment is improved.
本发明公开了一种发动机曲轴位置调整方法、装置及混合动力车辆。该发动机曲轴位置调整方法包括:判断车辆进入停机进程。根据判断结果,控制离合器闭合。获取发动机的曲轴的位置信息。根据发动机的曲轴的位置信息,控制离合器断开,以将发动机的曲轴的位置达到曲轴目标位置。本发明提供的技术方案可以减小电动机的补偿转矩值,并提高发动机曲轴位置调整的精确度。
