A Laboratory Evaluation of Tires for Directional Control 640399
Control of conventional vehicles in steering is based on development of lateral forces by the tires when operating at slip angles. However, the relationship between lateral force and slip angle is not always an adequate measure of the effectiveness of a tire in the process of control. Effects of load transfer must also be considered.
The paper outlines an approach for incorporating phenomenon of load transfer and certain aspects of the vehicle configuration into the scheme of evaluation. The technique is substantiated in comparative tests with vehicles on the road. Examples are given of its use in studying the effectiveness of light truck tires in directional control.
