Abstract
In order to overview the dynamic characteristics of vehicle, it is necessary to know the interrelationship of motion in each direction. For steering input, the three main movements are lateral, yaw, and roll. Among them, there are many studies on the relationship between lateral motion and yaw motion, as represented by rear wheel steering technology. In this paper, the relationship between roll motion and yaw motion are focused on, which has been rarely studied so far, and considered the characteristics of the relationship between the two motions. The structure of the transfer function of a linear 3-degrees-of-freedom model are theoretically analyzed, and verified by simulation calculations and experiments. As these results, the contribution of the design parameters that determine the response balance between roll and yaw are clarified.
