Development of an active motion system of tire contact point control

Abstract

This paper presents the possibilities of a direct wheel control system, which can optimize both cornering performance and turning radius. Tire contact patch position and toe angle can be controlled independently for the front wheels at both left and right hand sides using a robotic suspension system. Quasi-trivial modes such as different configurations of track width or wheelbase lead to a reduction on roll angle and weight transfer. A fully independent wheel control enables further a much more powerful cornering performance control. This paper describes the initial investigations on performance prediction.
