The invention discloses a hybrid degraded starting control method, relates to the field of engine starting, and solves the technical problem that a diesel engine cannot be independently started due to hardware problems, incapability of receiving a working request by a VCU (vehicle control unit) and abnormal communication between the VCU and a generator or an ECU (electronic control unit) of a hybrid system of an existing diesel engine. The method comprises the steps that the real-time electric quantity of a battery, the communication state between a VCU and a generator and the communication state between the VCU and an ECU are obtained, and whether an engine can be started independently or not is judged according to the real-time electric quantity of the battery, the communication state between the VCU and the generator and the communication state between the VCU and the ECU. Multi-mode starting is achieved, effective use of the vehicle under different conditions is guaranteed, safe use of the vehicle is effectively guaranteed, safety of a vehicle owner is guaranteed, and excessive hardware transformation and cost increase are not needed.

    本发明公开了一种混动降级起动控制方法,涉及发动机起动领域,解决了目前柴油发动机的混动系统由于硬件问题、VCU无法接收工作请求、VCU与发电机或者ECU通讯异常的原因使柴油机无法单独起动的技术问题。该方法为,获取电池的实时电量、VCU和发电机之间的通讯状态和VCU和ECU之间的通讯状态,根据所述电池的实时电量、VCU和发电机之间的通讯状态以及VCU和ECU之间的通讯状态来判断发动机是否能单独起动。本发明实现多种模式起动,保证不同情况下的车辆有效使用,有效保证车辆的安全使用,保证车主的安全,无需增加过多的硬件改造和成本增加。
