Abstract
In the automatic collision avoidance system that is one of the Intelligent Transport Systems (ITS), automatic braking and automatic steering can be considered as the collision avoidance method. In order to establish the automatic collision avoidance system, it is necessary to clarify the method and timing that contribute the minimum avoidance distance. For this issue, we reported the difference of minimum avoidance distance between automatic braking and automatic steering when these operate independently. It can be also, however, considered operation of automatic braking and automatic steering simultaneously as the avoidance method. The objective of this paper is to clarify the effect of the simultaneous operation by simulation of emergency obstacle avoidance. Consequently, the avoidance distance by the simultaneous operation is shorter than the one by the operation of automatic braking or automatic steering independently.
