Abstract
An active fault tolerance and fault mitigation system based on steer-by-wire dual motors and a mode switching control method thereof are provided. The system includes an acquisition unit, a steering wheel assembly, an ECU control module, a front wheel steering assembly, and a fault tolerance controller () which are sequentially connected. The acquisition unit transmits an acquired vehicle signal to the ECU control module, and then a corresponding compensation strategy is selected by means of a fault tolerance control strategy unit, a yaw rate calculation unit, a stability control unit, and a dual-motor compensation unit to act on a rack and pinion mechanism (). The system and method can perform switching in an active fault tolerance and fault mitigation mode to achieve optimal control of the real-time performance of a vehicle, thereby ensuring the driving performance and higher performance of the vehicle in a field fault condition.
