Abstract
Official abstract text for this publication.
A suspension device includes: a suspension including a damping device which damps a force generated between a vehicle body and a wheel; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when an acceleration of change in a stroke amount is less than a predetermined value determined in advance, when the acceleration of the change in the stroke amount is equal to or greater than the predetermined value, in which the stroke amount is an amount of displacement from a reference position of the wheel with respect to the vehicle body in an extension direction of the suspension.
First claim
Opening claim text (preview).
1 . A suspension device comprising: a suspension including a damping device which damps a force generated between a vehicle body and a wheel of a motorcycle; a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when an acceleration of change in a stroke amount is less than a predetermined value determined in advance, when the acceleration of the change in the stroke amount is equal to or greater than the predetermined value, the stroke amount being an amount of displacement from a reference position of the wheel with respect to the vehicle body in an extension direction of the suspension; and a predetermined value setting unit that sets the predetermined value such that the predetermined value is decreased as the stroke amount is decreased. 2 . The suspension device according to claim 1 , wherein the damping force control unit increases the damping force as the acceleration is increased. 3 . A suspension device comprising: a suspension including a damping device which damps force generated between a vehicle body and a wheel of a motorcycle; a first control unit that controls a damping force of the damping device using a speed of change in a stroke amount, the stroke amount being an amount of displacement from a reference position of the wheel with respect to the vehicle body in an extension direction of the suspension; a determination unit that determines whether the suspension goes into the most extended state under a first damping force controlled by the first control unit; and a second control unit that controls the damping force so as to be greater than the first damping force when the determination unit determines that the suspension goes into the most extended state. 4 . The suspension device according to claim 3 , wherein when the acceleration of the change in the stroke amount is equal to or greater than a predetermined value determined in advance, the determination unit determines that the suspension goes into the most extended state. 5 . The suspension device according to claim 4 , further comprising: a predetermined value setting unit that sets the predetermined value such that the predetermined value is decreased as the stroke amount is decreased. 6 . The suspension device according to claim 3 , wherein the second control unit increases the damping force as the acceleration of the change in the stroke amount is increased. 7 . The suspension device according to claim 4 , wherein the second control unit increases the damping force as the acceleration of the change in the stroke amount is increased. 8 . The suspension device according to claim 5 , wherein the second control unit increases the damping force as the acceleration of the change in the stroke amount is increased.
