TIME MARGIN OF DRIVER STEERING AVOIDANCE UNDER LATERAL DISTURBANCE

In previous research, experimental data of driver performance concerning the time margin to avoid a collision with an obstacle ahead of the vehicle was obtained. However, there are very few reports concerning the lateral time margin to avoid the lane departure when the vehicle is laterally disturbed. The purpose of this study is to clarify the temporal limitation of the driver's ability of steering avoidance, when the lateral disturbance is heavily acting on the vehicle with the timings being directly controlled in a driving simulator. The results of this experiments are as follows. In a situation of the expected obstacle appearance, all 13 drivers could avoid the lane departure when the lateral time margin was longer than 1.0 seconds. However, no subject could avoid the lane departure when the time margin was shorter than 0.7 seconds at 100km/h driving speed. On the other hand, in a situation of the unexpected obstacle appearance, the time margin of successful avoidance was increased by about 0.2 seconds. It is considered that a time margin longer than 1.0 seconds is effective to avoid the lane departure when the vehicle is laterally disturbed. For the covering abstract see IRRD E102946.
