An existing mathematical model of passenger vehicle handling was programmed for use in a hybrid computer simulation. The handling characteristics of a 1967 Ford Station Wagon and a 1971 Volkswagen Super Beetle were determined by exercising the simulation and by physical testing. The hybrid computer results were compared with subsequent test results to validate the simulation. Established Vehicle Handling Test Procedures were utilized to derive limits of vehicle performance. The simulation of Volkswagen handling accurately predicted the test results for straight line braking, braking in a turn, sinusoidal steering, and trapezoidal steering. Road holding and rollover tests imposed conditions which exceeded the available tire data and violated the assumptions of the suspension model so that quantitative prediction was compromised. Simulation versatility has been enhanced to accurately model several vehicle characteristics. In particular, both solid rear axle and independently sprung rear axle vehicles can be evaluated.
