The invention discloses a hybrid electric vehicle gear shifting control method and device. The method comprises the following steps: entering a gear shifting process according to a gear shifting request sent by a hybrid controller; in the process that the gear shifting executing mechanism executes gear shifting operation, the motor is controlled to output a certain torque so as to reduce resistance needing to be overcome in the sliding friction process of the conical surface of the synchronizer. According to the novel gear shifting method, by controlling the motor and supplementing proper torque in the friction stage of the conical surface of the synchronizer, the resistance needing to be overcome by the conical surface of the synchronizer can be reduced, the duration time of the speed synchronization stage is shortened, and the reliability and drivability of the hybrid electric vehicle are improved.

    本发明公开了一种混合动力汽车换挡控制方法和装置。其中,所述方法包括:根据混动控制器发出的换挡请求进入换挡过程;在换挡执行机构执行换挡操作的过程中,控制电机输出一定大小的扭矩,以减小同步器锥面滑摩的过程中所需克服的阻力。本发明所提出的新型换挡方法,通过控制电机,在同步器锥面摩擦阶段补充适当的扭矩,可减少同步器锥面所需克服的阻力并降低速度同步阶段的持续时间,提升了混动汽车的可靠性与驾驶性。
