The invention relates to the technical field of vehicle power system control, in particular to an REV type power assembly vibration reduction control system and method. Vibration information of an engine, a generator, a driving motor and a reduction gearbox in a power assembly in a hybrid mode of a vehicle is collected through a vibration sensor, collision pressure information of a clutch and the generator is collected through a pressure sensor, and then the vibration information and the collision pressure information are sent to a vibration reduction processor to be processed and calculated. The vibration reduction processor sends a signal to the engine controller and the reduction gearbox controller, so that the output torque and the rotating speed of the engine and the transmission ratio of the reduction gearbox are controlled, the vibration amplitude and the collision probability of all parts of the power assembly can be reduced, the noise of a cabin is reduced, and the service life of the power assembly is prolonged; and the driving experience of the vehicle is improved.

    本发明涉及车辆动力系统控制技术领域,具体涉及一种REV车型动力总成减振控制系统及控制方法。通过振动传感器采集车辆混动模式下动力总成中发动机、发电机、驱动电机和减速箱的振动信息,并通过压力传感器采集离合器和发电机的碰撞压力信息,然后将振动信息和碰撞压力信息发送给减振处理器进行处理和计算,再由减振处理器发送信号给发动机控制器和减速箱控制器,进而对发动机的输出扭矩和转速以及减速箱的传动比进行控制,能够减小动力总成各部件的振动幅度和碰撞概率,降低机舱噪音,提高动力总成的使用寿命,并提升车辆的驾驶体验。
