| Abstract(J) | ステアリングギア比を小さくすると，低速において特定の周波数の操舵入力に対する車両応答が敏感になり，乗り心地が悪化する．本研究では，上記挙動の原因がタイヤ緩和長の影響であることを明らかにし，これまでできなかった低速での低ギア比化の可能性を開拓した．本報では現象のメカニズムと対策について述べる． Translation |
| Abstract(E) | Vehicles with a low steering gear ratio become sensitive to steering inputs of a specific frequency when driving at low speeds, which leads to poor riding comfort. It was clarified that this phenomenon occurs depending on the tire relaxation length and its mechanism. In a steer-by-wire vehicle, it was clarified in an actual vehicle experiment that it is possible to take measures against the above phenomenon by installing an appropriate filter between the steering wheel angle and the front wheel steering angle. |
