The invention provides a vehicle power system control method and system, a power system and a vehicle, and relates to the technical field of vehicles, based on the vehicle power system, the vehicle power system comprises a first motor, a second motor and a multi-mode clutch; the multi-mode clutch comprises an outer ring and an inner ring, the outer ring and the inner ring are coupled or separated, the outer ring is used for being in transmission connection with wheels, the first motor is in driving connection with the outer ring, and the second motor is in driving connection with the inner ring; the vehicle power system control method comprises the steps that in response to an abnormal signal of a first motor, whether a vehicle meets a driving condition or not is judged, and the driving condition includes that the vehicle is in a downhill road section; and when the vehicle meets the driving condition, the multimode clutch is controlled to be coupled, so that the second motor drives the vehicle to run through the multimode clutch. Continuous driving of the vehicle is achieved, it is ensured that the vehicle can be driven through the power generation motor even if the driving motor fails, and the anchoring risk is effectively avoided.

    本发明提供了一种车辆动力系统控制方法、控制系统、动力系统及车辆,涉及车辆技术领域,基于车辆动力系统,车辆动力系统包括第一电机、第二电机和多模离合器;多模离合器包括外圈和内圈,外圈与内圈耦合或分离,外圈用于与车轮传动连接,第一电机与外圈驱动连接,第二电机与内圈驱动连接;车辆动力系统控制方法包括:响应于第一电机的异常信号,判断车辆是否满足驱动条件,其中,驱动条件包括车辆处于下坡路段;当车辆满足驱动条件时,通过控制多模离合器耦合,以使第二电机通过多模离合器驱动车辆行驶。实现对车辆的持续驱动,确保车辆即使在驱动电机失效的状态下,可通过发电电机驱动,有效避免抛锚风险。
