To improve accuracy of grounding load control of an outer ring and an inner ring at the time of turning a vehicle.SOLUTION: A damping force control method comprises the steps of: detecting or estimating lateral acceleration of a vehicle (S3); and configuring, when the lateral acceleration is a prescribed value or more, a right and left distribution ratio that is a distribution ratio of damping force of a damping force variable damper between an outer ring and an inner ring based on a damping force ratio of damping force at expansion to damping force at compression when the damping force variable damper is compressed or expanded at the same stroke speed so that the damping force of the damping force variable damper of the outer ring that is a wheel at an outer side during turning is to be larger than the damping force of the damping force variable damper of the inner ring that is a wheel at an inner side during turning (S6).SELECTED DRAWING: Figure 12
【課題】車両の旋回時における外輪及び内輪の接地荷重の制御の精度を向上する。【解決手段】減衰力制御方法では、車両の横加速度を検出又は推定し(S3)、横加速度が所定値以上である場合に、旋回外側の車輪である外輪の減衰力可変ダンパーの減衰力が旋回内側の車輪である内輪の減衰力可変ダンパーの減衰力よりも大きくなるように、外輪と内輪との間の減衰力可変ダンパーの減衰力の配分比である左右配分比を、減衰力可変ダンパーが同じストローク速度で圧縮及び伸長する際にそれぞれ生じる圧縮時の減衰力に対する伸長時の減衰力の比である減衰力比に基づいて設定する(S6)。【選択図】図12
