According to the steering system of a commercial vehicle, the overall layout of the dual motor electric power steering system (EPS) is designed, based on the PID control method, the design of power distribution scheme and fault tolerant control algorithm is presented. According to the vehicle parameters, the vehicle dynamics model is built by ADAMS, and the simulation model of dual motor EPS commercial vehicle was established in Matlab/Simulink. The assistant current distribution scheme and power assisted control strategy are studied by the joint simulation. Through the double wire test, it is verified that the designed control strategy has better steering portability. |
