Passenger Motion Control with Steer and Acceleration/Deceleration Combined Operation for Ride Quality Improvement

Abstract

The acceleration caused by vehicle motion is applied to passenger body as an inertia, then it affects to ride quality. Therefore, we had explored the possibility to control passenger body motion with both lateral inertia generated by steer control and longitudinal inertia by driving force control (acceleration and deceleration). We have taken the resultant inertia effect into consideration, then verified its effect for passenger body motion with experiment. Derived physical passenger body motion model are used to derive optimal vehicle movement to minimize passenger motion. Experiments based on optimal simulation verified the possibility to control passenger body motion more effectively.
