Difference of Steering Maneuver on Right and Left Turn Depends on Driver

Abstract

In this paper, we discuss the difference of driver's characteristics. Nowadays, driver assist systems are developed. It is very important to develop an effective driver assist system. We focus our attention on steering maneuver. We performed the experiment using the actual car. In the experiment, we measured not only a vehicle state but also the force acting on steering wheel and the motion of driver's arm. The six-degree-force transducer on steering wheel is newly developed. The motion capture system using supersonic wave is adapted. We found three kinds of characteristic maneuvers. First, it is the difference of steer angle. A beginner driver steers with high frequency. On the other hand, an expert driver steers without high frequency. Next, we investigated the location of grabs on steering wheel of each subjects. The beginner grabs particular place of steering wheel. They don't cross their arms during cornering. Finally, we found the difference of characteristic about pushing and pulling force on steering wheel.
