Abstract
This paper describes the modeling of a man-automobile system based on the a psychological man-machine model. The driver who must adapt to the frequently changing external environment in driving is receiving the psychological stress. Among variety of stimulations in driving, he selects some of them which may give him the injury and threat and/or to which he must pay effort to resolve, and percepts them as the noxious stressors. And, he begins to take action called coping to reduce the noxious factors in the stressor. This is an influential hypothesis of the psychology. If the driver drives the automobile based on this hypothesis, he keeps injury and threat away, releases himself from the vigilant mental situation and drives the automobile in the safe manner.
Under the hypothesis above, we built a driver-automobile model and formulated the minimum-stress driving problem. The driving mode derived from the solution of the problem, is similar to that of human actual driving as well as the driving control structure is same as that of the conventional pre-view control well-known in the automobile engineering field. The simulation results and an unmanned vehicle controlled by the proposed formulation, shows the safe driving as man drive.
