The embodiment of the invention relates to a control method and device for a hybrid vehicle and a vehicle control unit, and the method comprises the steps that when it is determined that a power battery meets a preset power-off condition, an engine is controlled to drive the vehicle according to the current motor torque of a first motor, and the torque of the first motor and the torque of a second motor are controlled to be reduced to zero, the first motor is located between the engine and the transmission. The second motor is located at the front end of the engine and connected with a crankshaft of the engine. And when the first motor and the second motor both meet the preset zero torque entering condition, the first motor and the second motor are controlled to enter a preset standby mode. According to the technical scheme, the problems of overtemperature of the power battery, serious fluctuation of voltage and the like caused by the fact that the motor is directly controlled to enter the preset standby mode from the torque working mode when the power battery of the vehicle has a fault needing to be powered off are solved.

    本公开实施例涉及一种混动车辆的控制方法、装置及整车控制器,其中该方法包括:在确定动力电池满足预设断电条件时,控制发动机根据第一电机的当前电机扭矩驱动车辆,并控制第一电机和第二电机降低至零扭矩,其中,第一电机位于发动机和变速器之间,第二电机位于发动机的前端且与发动机的曲轴连接;在第一电机和第二电机均满足预设零扭矩进入条件时,控制第一电机和第二电机进入预设待机模式。在本技术方案中,避免了车辆的动力电池发生需要断电的故障时,直接控制电机由扭矩工作模式进入到预设待机模式,导致动力电池超温、电压上下波动严重等问题。
