Abstract:
(EN) This control device for a suspension device is provided with an acquisition unit 111 that acquires the stroke quantity of the suspension device, a calculation unit 112 that calculates the stroke speed, and a damping force control unit that controls the damping force of the suspension device. The calculation unit 112 is provided with: a first calculation unit 112a that uses a first time constant as a time constant to differentiate the stroke quantity and that calculates a first stroke speed; and a second calculation unit 112b that uses a second time constant that is greater than the first time constant as a time constant to differentiate the stroke quantity and that calculates a second stroke speed. The calculation unit 112 calculates the stroke speed on the basis of the first stroke speed and the second stroke speed.
(FR) L'invention concerne un dispositif de commande pour un dispositif de suspension comprenant une unité d'acquisition (111) qui acquiert la quantité de course du dispositif de suspension, une unité de calcul (112) qui calcule la vitesse de course et une unité de commande de force d'amortissement qui commande la force d'amortissement du dispositif de suspension. L'unité de calcul (112) comporte : une première unité de calcul (112a) qui utilise une première constante de temps comme constante de temps pour différencier la quantité de course et qui calcule une première vitesse de course; et une seconde unité de calcul (112b) qui utilise une seconde constante de temps qui est supérieure à la première constante de temps comme constante de temps pour différencier la quantité de course et qui calcule une seconde vitesse de course. L'unité de calcul (112) calcule la vitesse de course sur la base de la première vitesse de course et de la seconde vitesse de course.
(JA) 懸架装置用の制御装置は、懸架装置のストローク量を取得する取得部111と、ストローク速度を算出する算出部112と、懸架装置の減衰力を制御する減衰力制御部と、を備え、算出部112は、時定数として第1の時定数を用いてストローク量の微分を行ない第1のストローク速度を算出する第1算出部112aと、時定数として第1の時定数より大きい第2の時定数を用いてストローク量の微分を行ない第2のストローク速度を算出する第2算出部112bとを備え、第1のストローク速度および第2のストローク速度を基にストローク速度を算出する。
