Design and control of the steering torque feedback in a vehicle driving simulator

Vehicle driving simulators allow engineers to evaluate subjectively the virtual prototype in early concept phase. Steering torque feedback as one of the basic haptic cues is usually provided by a servo motor through a force feedback system. The artificial feedback torque calculated from the vehicle model and sent to the servo motor is distorted by this interface. In this paper, it is investigated how the force feedback system dynamics influences the artificial steering feedback. To mask the dynamics of the force feedback system a feedforward compensation method based on the steering states has been proposed when driver is in the loop.
