In recent years, the conversion of vehicles to electric power has beenaccelerating, and if a full conversion to electric power is achieved, furtheradvancements in vehicle kinematic control technology are expected. Therefore,it is thought that kinematic performance in the critical cornering range couldbe further improved by significantly controlling not only the steering anglebut also the camber angle of the tires through the use of electromagneticactuators. This research focused on a method of ground negative camber anglecontrol that is proportional to the steering angle as a technique to improvemaneuverability and stability to support the new era of electric vehicles, andthe effectiveness thereof was clarified. As a result, it was found that in thecritical cornering range as well, camber angle control can control both the yawmoment and lateral acceleration at the turning limit. It was also confirmedthat both stability and the steering effect in the critical cornering range areimproved by implementing ground negative camber angle control that isproportional to the steering angle using actuators. Dramatic improvements incornering limit performance can be achieved by implementing ground negativecamber angle control that is proportional to the steering angle.
