A comparison study of road condition cognition by visual and torque feedback

The traffic accident becomes social trouble along with the driver's increase and diversification. To solve this problem, the driving support system that everyone can drive a vehicle always safely is required. Then, the electric vehicle(EV) come under the spotlight in recent years. In this paper, the comparison between torque feedback and visual feedback is conducted to show the validity of force feedback communication. First, driving force and slip ratio is estimated and road condition is culcuated. Second, the slipping restrain by the feedback of road condition in torque to driver with haptic pedal. Then visual indicator to show the road condition is also constructed. Finally, each strategy is evaluated by several numerical results.
