Description

本発明は、車体を懸架する車両用サスペンション装置およびそのジオメトリ調整方法に関する。 The present invention relates to a vehicle suspension system and its geometry adjustment how suspending a vehicle body.

（１１）直進性担保部は、セルフアライニングトルクを算出して直進性を担保している。
したがって、直進性担保部で、サスペンション装置の高応答性を確保することにより低下した直進性をセルフアライニングトルクで担保することができ、操縦・安定性を向上させることができる。
（１２）直進性担保部は、少なくともコンプライアンスステアを推定して転舵輪の変位補正を行うようにした。
したがって、サスペンション装置を構成するロアアームの車体側支持部に介挿したブッシュの剛性を低下させることが可能となり、車両の乗心地を向上させることができる。 (11) The straightness guaranteeing part secures straightness by calculating self-aligning torque.
Therefore, the straight travel performance guaranteeing section can secure the straight travel performance reduced by securing the high responsiveness of the suspension device with the self-aligning torque, and the steering and stability can be improved.
(12) The straight travel guarantee part estimates at least the compliance steer and corrects the displacement of the steered wheels.
Therefore, the rigidity of the bush inserted in the vehicle body side support portion of the lower arm constituting the suspension device can be reduced, and the riding comfort of the vehicle can be improved.

この結果、低車速領域では、直進担保制御の開始が遅くなるので、サスペンション装置１Ｂで設定される高応答性の転舵応答性で機敏な操舵状態を得ることができる。また、中速領域では、直進担保制御の開始が中庸の範囲となって、適度な操舵応答性の操舵状態を得ることができる。さらに、高速領域では、直進担保制御の開始が速くなるので、サスペンション装置１Ｂで設定される高応答性の転舵応答性が早めに抑制されて安定性の良い操舵状態を得ることができる。 As a result, in the low vehicle speed region, the start of the straight traveling collateral control is delayed, so that it is possible to obtain an agile steering state with a highly responsive turning response set by the suspension device 1B. Further, in the medium speed range, the start of the straight collateral control is in the middle range, and a steering state with an appropriate steering response can be obtained. Furthermore, in the high-speed region, since the start of the straight travel guarantee control becomes fast, the highly responsive turning responsiveness set by the suspension device 1B is suppressed early and a stable steering state can be obtained.
