AUTOMOBILE STABILITY AND CONTROL ANALYSIS BY THE MOMENT METHOD

This report contains the results of an investigation of the stability and control characteristics of six generic automobile designs as determined by the Calspan Moment Method Computer Simulation Program. These results are presented in the form of performance diagrams that relate the principal operating conditions, control input variables, and motion responses in an integrated plot. Information on the physical and functional properties of the vehicle-tire combinations that were evaluated in the study are given. The array of operating conditions--emphasizing the effects of tire performance characteristics on response--is described. This array includes tire construction, inflation pressure, and match-mixture factors; it encompasses vehicle weight, wheelbase, driving axle, and speed variables; operational modes of road load, throttle closure, and two levels of braking deceleration are covered; and a number of special considerations (loading, low surface skid number, braking capability proportioning, and temporary tire usage) are addressed. In-depth analyses of the results are not offered in this report, but many of the observations relating variations in these factors and performance changes are discussed in SAE Paper No. 830561.
