Steering torque feedback provides drivers with road feel and hap tic feedback on vehicle motion, which are necessary for drivers to properly operate vehicles. Therefore, simulating steering torque feedback with sufficient fidelity is of great significance to systems without actual steering systems, such as driving simulators and steer-by-wire systems. In this paper, a steering torque feedback model is developed and a global sensitivity analysis method is used to identify the influence degree of each model parameter on steering feel properties for on-center performance. The analysis results provide useful guidelines on how to configure steering characteristics to obtain accurate and tunable steering feel.
