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

車両横加加速度に基づくヨーモーメント制御手法の検討(第2報)

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.「横加加速度を速度で除した値に比例したヨーモーメント」を加える制御則(M+/V)を新たに提案し,2輪モデルを用いて解析を行った結果,制御の主成分は,「横すべり角によるヨーモーメント成分」の位相進み/遅れで表現でき,外乱の影響を小さくするメカニズムが形成され,安定性が改善できることを確認した.
