Abstract
To improve both the sensing of grip critical cornering and drift control, it is desirable to increase the body slip angle at critical cornering. To discover why this facilitates driver control, the gaze of the driver was monitored, and the relationship between the gaze movement of the driver and the vehicle behavior was investigated. It was found that the driver steered by gazing at the target course in the direction of the inside forward of the vehicle in the grip driving area. On the other hand, the gaze movement of the driver corresponded to the change in the body slip angle in the grip critical cornering area-drift cornering area. That is, in the drift driving area, it was found that the drift was controlled by gazing at the direction of the drift angle of the outside forward of the vehicle, feeding back the body slip angle, and sensing the change from the grip critical cornering to the drift area. That is, the relationship between the vehicle behavior in critical cornering and gaze movement at the time of sensing of critical cornering was clarified. Therefore, by increasing the body slip angle during grip critical cornering, the driver easily adjusts the body slip angle to feedback in the gaze, which results in improved sensing of grip critical cornering. In addition, because the driver adjusts the gaze feedback of the change from the grip area to the drift area easily, drift control is improved.
