The Role of Rear Cornering Stiffness in Vehicle Directional Dynamics


The transfer functions between the variables in linear bicycle models of four wheel automobiles, the input to which is steering angle, were examined. The modal response transfer functions between all of the motion outputs, with the exception of front tire slip angle, were found to be independent of front tire cornering stiffness. It is a role unique to rear cornering stiffness to define the above mentioned transfer functions. This concept was also deductively demonstrated, providing additional insight into the physical basis of the proposition.前輪舵角を入力とする線形2輪モデルの各出力変数間の伝達関数を吟味し,前輪タイヤ滑り角を除く出力変数間の相互の伝達関数は前軸コーナリングスティフネスに依存せず,これら伝達特性の決定は,前軸横力特性には果たし得ない後軸横力特性固有の役割であることを示した.また,こうなる力学的メカニズムも示した.
