Abstract
If the vehicle dynamics can be identified when the vehicle actually runs, it enables to control the vehicle motion and to assist the driving manuever adaptively. In this paper we try to identify the vehicle dynamics in single lane change that is ordinary driving behavior in an actual traffic. As the identification method, the ARX model with the least square method for the parameter fitting is used. It is applied to the simulation data of the lane change. It is clarified that this method is useful for the identification of the vehicle dynamics from lane change situations.
