Description

<p>Steering reactive torque presentation is one of driving support systems for a steer-by-wire(SBW) vehicle, and it would inform the road surface condition and the working state of the system. However, driver's sensory characteristics for the steering reactive torque are not known very well, and therefore, the steering reactive torque gain is decided by trial and error. The present paper performs experiments using a haptic interface which can provide arbitrary steering reactive torque to subjects, and it would elucidate the haptic characteristics for the change of the steering reactive torque in the case of a periodic steering and a constant steering. Moreover, the driving simulator experiments which simulate the actual driving environment are performed to verify the effect of the steering reactive torque amplitude on the driving behavior and the subjective evaluation.</p>
