Title:
SUSPENSION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/195295
Kind Code:
A1
Abstract:
A controller as a control device is provided with a vertical acceleration correction operating unit and a damping force command operating unit. The vertical acceleration correction operating unit has a straight-direction slope calculation means (longitudinal slope calculation unit) for calculating the degree of inclination of a road surface in the straight direction of a vehicle (longitudinal slope θ), and an orthogonal slope calculation means (bank slope calculation unit) for calculating the degree of inclination of the road surface in a direction orthogonal to the straight direction of the vehicle (cross slope φ), and is configured to calculate corrected sprung vertical acceleration (corrected vertical acceleration αzco) with respect to a vertical acceleration sensor value αzsens of a sprung acceleration sensor by correcting the vertical acceleration sensor value αzsens by the longitudinal slope θ and the cross slope φ.
