Abstract
Various control systems for vehicle dynamics have been proposed. In future, it is important to use four tires efficiently with considering tire force usage in order to further enhance vehicle dynamics. Recently, research on "Smart Tire" which can measure in each direction forces between road surface and tires in real time is actively conducted. This paper focuses on the tire force distribution control, so-called DYC (Direct Yaw-moment Control) +Usage control, which optimizes tire force usage by using the information of tire forces acting between road surface and tires. The DYC +Usage control algorithm is presented and its control effect is analyzed by computer simulation.
