Abstract

Using conventional technology, it used to be difficult to calculate vehicle behavior in a limit handling situation by mechanical system analysis and predict that behavior with a high degree of accuracy. Tire modeling based on Magic Formula was optimized for limit behavior, and represented tire deflection.. Further, suspension rate and traction torque control were improved based on the conventional vehicle model. These measures have made it possible to perform mechanical system analysis calculation of vehicle handling behavior up to the limit. As a result, it has become possible to attain a high degree of accuracy in predicting vehicle limit behavior in turn, which is one of the dynamic characteristics for limit drivability.
