The invention discloses a hybrid vehicle driving mode switching control method and device, and relates to the technical field of vehicle driving mode switching control. According to the technical scheme, when the hybrid vehicle executes driving mode switching, whether the lock control action is executed on the engine of the hybrid vehicle or not is determined, and when it is determined that the lock control action needs to be executed, the generator of the hybrid vehicle is driven to output the preset torque to the engine, and the preset lock control executing mechanism is controlled to execute the lock control action; according to the method and the strategy, the locking action for controlling the engine to stop rotating and the unlocking action for controlling the engine to start running can be executed more smoothly, and the collision loss of mechanical parts in the lock control action execution process is reduced; and therefore, the reliability of the hybrid vehicle in the driving mode switching process is improved.

    本发明公开了一种混动车辆驱动模式的切换控制方法和装置,涉及车辆驱动模式切换控制的技术领域。本发明的技术方案通过在混动车辆执行驱动模式切换时,确定是否对混动车辆的发动机执行锁控动作,在确定需要执行锁控动作时,驱动混动车辆的发电机对发动机输出预设扭矩,并控制预设的锁控执行机构执行锁控动作;使发电机配合锁控执行机构完成锁控动作,该方法策略能够控制发动机停止转动的锁止动作和控制发动机启用运转的解锁动作执行更平顺,减小锁控动作执行过程中机械部件的碰撞损耗,进而提高了混动车辆在驱动模式切换过程中的可靠性。
