Experimental evaluation on effect of steering reactive torque of SBW vehicle on driving behavior

Steering reactive torque presentation is important for drivers of a steer-by-wire (SBW) vehicle to inform of the driving environment such as the road surface condition and the working state of the SBW controller. However, we have to solve the problem how to decide the steering reactive torque gain. Therefore, in the present paper, the driving simulator experiments which simulate the actual driving environment are performed to verify the effect of the steering reactive torque on the driving behavior and the subjective evaluation.
