Title:
CONTROL DEVICE FOR SUSPENSION DEVICE, DIFFERENTIAL CALCULATION DEVICE, RECORDING MEDIUM, AND SUSPENSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/003455
Kind Code:
A1
Abstract:
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.
