Study on Yaw-moment Control Method Based on Vehicle Lateral Jerk Information (Second Report)

- Deep Understanding of Mechanism through the Analysis Using Bicycle Model -

Abstract

A new yaw-moment control method which generates enhancing/stabilizing moment in accordance with vehicle lateral jerk divided by vehicle speed was analyzed. The analysis using the linear plane bicycle model showed the natural frequency of the controlled vehicle was increased, however, damping ratio was decreased. The improvements of yaw response for especially over-steer vehicle were confirmed. Moreover, the control improved the stability by detecting derivative of disturbance force from vehicle lateral jerk.
