Abstract
The objective of the investigation is to provide a basis for judging whether or not the dynamic steering adjustments of the tire forces affect vehicle performance in a significant manner.
The differential equation of cornering force adjustment is developed from experimental data. This equation is applied, for a typical radial ply tire, to a crude but sufficient mathematical model of a vehicle. The responses of the vehicle in certain maneuvers differ to some degree when the model is programmed with instantaneously reacting tires or with simulations of actual tires.
The authors judge that there are slight and unimportant effects on the path and heading curves of the vehicle due to the delays in build-up cornering force. On the other hand, there appear to be detectable effects that may be important in the sensory information provided to the driver.
