Abstract

A force feedback model of steering wheel was established based on mechanical analysis of the vehicle steering system. Taking driver’s preference for steering torque into consideration, a correction coefficient was introduced to this model, and a method for determining the coefficient was also put forward. To study on the steering wheel return control strategy, the relationship between torque and speed as well as voltage of the torque motor was analyzed by interpolation fitting. In addition, the simulated control model in Matlab/Simulink was set up. As for the oscillation problem, in order to improve the steering wheel returnability, Improvement of control strategy of torque motor was proposed. The model was further optimized through the research of the influence of different elastic coefficient and damping coefficient on steering wheel returnability. Finally, the real experiment proved the feasibility of the model and control strategy.
