Abstract
The purpose of this paper is to study the cornering resistance and dissipation power on tyre contact patch during acceleration and deceleration while turning. Our method to formulate the cornering resistance in steady state cornering was extended to quasi steady state cornering. The simulation revealed that the reduction effect of dissipation power by direct yaw moment emerges due to the load shift between front and rear wheels. The optimization method proved that the optimum direct yaw moment is achieved by equalization of slip vectors of all the wheels. Moreover, this paper discussed the effect of the direct yaw moment control on vehicle handling performance. As a consequence, this control also enhances the stability of vehicle motion.
