The invention provides a hybrid power vehicle engine starting method and a hybrid power vehicle, is applied to a hybrid power vehicle with a double-clutch transmission, and relates to the technical field of hybrid electric vehicles. The vehicle control unit sends the target gear and the current gear to a gearbox controller; the target gear is higher than the current gear, and the transmission ratio of the target gear is smaller than that of the current gear; after the gearbox controller receives the target gear and the current gear, a gearbox synchronizer is controlled to conduct adjustment according to the target gear and the current gear; and the engine controller starts the engine after the gearbox synchronizer completes adjustment. Therefore, the problem of power loss of the wheel end generated in the engine starting process of the hybrid power vehicle is solved in a mode of reducing the transmission ratio.
本申请提供了一种混合动力车辆发动机启动方法及混合动力车辆,应用于双离合器变速器混合动力汽车,涉及混合电动车辆技术领域,当混合动力车辆由电机驱动模式转换为发动机驱动模式时,整车控制器向变速箱控制器发送目标档位和当前档位;所述目标档位高于所述当前档位,且所述目标档位的传动比小于所述当前档位的传动比;所述变速箱控制器在接收所述目标档位和所述当前档位后,控制变速箱同步器根据所述目标档位和所述当前档位进行调整;发动机控制器在变速箱同步器完成调整后,启动发动机。从而利用降低传动比的方式,解决了混合动力车辆启动发动机过程中产生的车轮端的动力损失问题。
