Study on the Control Algorithm of Driving Assistance System to Inhibit the Over-Dependence on the System

Abstract

There are various factors that are concerned with the over-dependence on driving assistance system. In this study, we focused on the interference level of driver behavior and system operation, and also focused on the unpleasantness level during system operation, for designing Forward Collision Avoidance Assistance System. It was proven that all subjects initiated the braking operation in advance of system actuation (i.e., no interference was observed) to minimize the risk of collision and dependence level on the system was extremely small, when the target stopping point was set at the backward of the obstacle and the deceleration level was set at 6.0 m/s² and more. It was also proven that all subjects canceled the system operation to minimize the unpleasantness and the dependence level on the system was extremely small, when the deceleration level is 6.0 m/s² and more.
