Abstract
There is currently a demand for vehicles with high stability and fuel efficiency. The authors have conducted research into camber control that aims to achieve both vehicle stability and fuel efficiency enhancement. In previous studies, using a model vehicle, camber was confirmed to be effective for improving cornering ability and energy conservation. For the purpose of further improving fuel efficiency, the proper combination of camber control and tires with partitioned low-loss/high-grip treads was implemented, and shown to result in both reduced fuel consumption and improved braking performance. The aim of the current paper is to show a quantitative improvement in driving stability due to camber. Because it was difficult to show the effect quantitatively using real vehicles, a computational model was constructed. The camber effect was demonstrated quantitatively by analyzing the vehicle model tire lateral force.
