Based on the mechanism of a differential steering system for electric vehicle with motorized wheels, the concepts and quantitative expressions of the road feel, sensitivity, and operation stability of the steering were proposed. Then, based on the traditional simulated annealing algorithm, an ASA algorithm was designed. With the road feel of the steering be optimization objectives, and operation stability and sensitivity of the steering be constraint, the system parameters were optimized. The simulation results show that the system optimized with ASA algorithm can improve the steering road feel, and guarantee the operation stability, steering sensibility; thus providing a theoretical basis for the design and optimization of the electric vehicle with motorized wheels system.
