Abstract
Progress of electronic control technology has contributed to the improvement of vehicle maneuverability. Vehicle maneuverability is related closely to drivability, and important for the activities toward zero-traffic-accident. Vehicle stability is also important characteristic in the vehicle dynamics area. To achieve the stability requirement, passive toe angle variation like bump-steer, or roll-steer characteristics were installed to the vehicle. Usually, it is difficult to achieve maneuverability and stability requirement at the same time. Electronic controled devices are helpful to achieve this. In this research, stability and maneuverability were investigated with a vehicle installed devices for both front and rear wheel control. And new control algorithm considering the yaw rotation center position control was installed and investigated. Through the vehicle evaluation, it was proved that this control system could contribute to improvement of maneuverability and stability.
