ABSTRACT: In recent years, the conversion of vehicles to electric power has been
accelerating, and if a full conversion to electric power is achieved, further
advancements in vehicle kinematic control technology are expected. Therefore,
it is thought that kinematic performance in the critical cornering range could
be further improved by significantly controlling not only the steering angle
but also the camber angle of the tires through the use of electromagnetic
actuators. This research focused on a method of ground negative camber angle
control that is proportional to the steering angle as a technique to improve
maneuverability and stability to support the new era of electric vehicles, and
the effectiveness thereof was clarified. As a result, it was found that in the
critical cornering range as well, camber angle control can control both the yaw
moment and lateral acceleration at the turning limit. It was also confirmed
that both stability and the steering effect in the critical cornering range are
improved by implementing ground negative camber angle control that is
proportional to the steering angle using actuators. Dramatic improvements in
cornering limit performance can be achieved by implementing ground negative
camber angle control that is proportional to the steering angle.
