Study on the Fault Tolerance Control Strategy of the Distributed Driving Electric Vehicle Running in Straight Line with Failure Motor(s)
The problem of motor fault tolerance of the distributed driving electric vehicle running in straight line is discussed and solved in the paper.The researched vehicle is designed with four in-wheel motors.The motor fault types are divided more detailed.To achieve a good riding stability and dynamic property with motors in failure state,some motor fault tolerance control strategies are proposed based on the performance of the distributed driving electric vehicles.And their mathematic models are established and simulated by MATLAB/Simulink software.The results indicate that the control strategies for torque re-allocation with motor(s) in failure state can achieve the designed demands well,and the dynamic performance of the distributed driving electric vehicle has been enhanced.
