The invention discloses a gear shifting control method and device of a hybrid power vehicle, and relates to the technical field of vehicle gear shifting control. According to the gear shifting control method, the wheel end demand torque and the running speed of the hybrid power vehicle are obtained, and whether the target state of switching the direct drive gear is achieved or not is determined according to the wheel end demand torque and the running speed; the gear for locking the generator in transmission connection with the engine can meet the control indexes of the basic dynamic property and the economic fuel property, and the hybrid power vehicle is directly switched to the direct-drive gear when meeting the switching condition of the direct-drive gear; and when the switching condition is not met, the hybrid power vehicle is controlled to run at other driving gears, and the hybrid power vehicle is shifted to the direct-drive gear in time when the target state is reached. By means of the control mode, the response level of the direct-drive gear can be higher, and then the dynamic property and the energy consumption economical efficiency are both considered in the driving process of the hybrid power vehicle.
本发明公开了一种混合动力车辆的换挡控制方法和装置,涉及车辆换挡控制的技术领域。换挡控制方法通过获取混合动力车辆的轮端需求扭矩和行驶车速,根据轮端需求扭矩和行驶车速,确定是否达到切换直驱挡位的目标状态,由于直驱挡位为混合动力车辆的驱动电机和发动机均对轮端输出扭矩,且对传动连接发动机的发电机进行锁止的挡位,能够满足基础动力性和经济燃油性的控制指标,在混合动力车辆满足直驱挡位的切换条件时直接切换至直驱挡位;不满足切换条件时,控制混合动力车辆以其他驱动挡位行驶,并在达到目标状态时及时换挡至直驱挡位。该种控制方式可以使直驱挡位的响应等级更高,进而使混合动力车辆的行驶过程中兼顾动力性和能耗经济性。
