Abstract

This study deals with estimation method for lateral tire force characteristics of an actual road using longitudinal force to measure. Based on the braking force characteristic measurement on the actual road conducted in the previous research, a brush model is used to estimate the lateral force characteristic based on the obtained μ-s characteristic. Each brush on the brush model has an adhesion region and a sliding region, so from the relationship of static friction characteristics, and dynamic friction characteristics, this model is extended from the longitudinal force to lateral force. For this transform, the adhesion region and the sliding region are estimated based on the braking force characteristics identified by the magic formula, using a tangential equation for simple magic formula, these two regions are estimated, and an algorithm for lateral force characteristic estimation is constructed.
