A theoretical study of the influence of tire-mechanics characteristics on the behavior of an automobile undergoing maneuvers requiring the tires to produce combined longitudinal and lateral forces was performed. A simulation model specifically designed to study vehicle response under skidding and near-skidding conditions was developed and mechanized on an analog computer. The model included a representation of wheel rotational degrees of freedom, and relationships expressing the longitudinal and lateral tire shear force components as analytical functions of tire normal load, sideslip and inclination angles, and longitudinal slip. The simulation was applied to examine the influence on vehicle responses to various open-loop steering and brake-control inputs of variations in the values of three parameters: lateral tire stiffness, longitudinal tire stiffness, and the coefficient of friction at the tire-road interface.
