This paper focuses on the fault tolerant control strategy for four-wheel-indenpendently-driving electric vehicle. For there are four or even more drive motors in the distributed driving vehicle, the probability of motor failure is greater compared with that of the single motor drive. Without proper control, the motor failure can lead to dangerous situations such as off tracking and violent spin of the vehicle. In this paper, the motor failure is firstly categorized into several modes. For each failure mode, relevant control strategy is then put forward to redistribute the driving torque to maintain driving stability and power performance. The torque distribution is further optimized to achieve good efficiency. A simulation is then carried out with an eight-degree of freedom vehicle model in Matlab/Simulink to verify the proposed control strategy.
