Abstract
Throughout the development of a small sized passenger car, a simulation method using digital computer has been proved to be useful in achieving the desired dynamics. Among the types of independent rear suspension systems available, the semi-trailing type has been shown preferable because of its negligible effect on jack-up. Ride motion is discussed within the concept of ''dynamical pitching centers''. In some cases, shock absorbers proved very effective in controlling the pitching mode. A system having four degrees of freedom was used for the analysis of steering response. A practical method for evaluating driver reaction is proposed.
