自動車のペダル踏み間違い事故防止方法の検討

抄録

It is difficult for drivers to prevent pedal misapplications by themselves. In this paper, we propose a system that immediately informs the driver that he/she is pressing the accelerator pedal by means of a tactile vibration of the pedal. An eccentric motor mounted on the back of the pedal generates a constant vibration with a fixed period only when the accelerator pedal is depressed. An experiment has been conducted with a driving simulator to investigate whether the pedal vibration system is effective in preventing pedal misapplication accidents and whether it is accepted by drivers. We induced pedal misapplications on a driving simulator and observed reactions of experiment participants. As a result, it was found that the pedal vibration system allowed drivers to notice pedal misapplication more quickly and to correct their foot position more rapidly. Therefore, the pedal vibration system is effective in preventing accidents caused by pedal misapplications. However, many experimental participants felt discomfort while driving.
