  A dual-motor electric power steering system suitable for commercial vehicles was designed. Based on ADAMS/Car, the multi-body dynamics model of the vehicle is established, and the basic assist characteristic curve of the commercial vehicle is given. Then the current distribution and fault-tolerant control scheme of two dual-motor EPS systems are proposed. Finally, based on MATLAB/Sim- ulink, the control model of EPS is established. The feasibility and fault tolerance of current distribution control strategy proposed in this paper are verified by co-simulation.
