Title:
SUSPENSION CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/066624
Kind Code:
A1
Abstract:
The present invention comprises: a vehicle behavior detection unit (acceleration sensor); an electrorheological damper that is disposed between a vehicle body 1 and wheels 2; and a controller that controls the damping force of the electrorheological damper so as to be adjusted on the basis of the detection result of the vehicle behavior detection unit. The controller is provided with: a target voltage value setting unit (damping force command calculation unit) that determines a target voltage value to be applied to an electrode tube on the basis of the detection result of the vehicle behavior detection unit; and a target voltage value correction unit (output limiting unit) that has a temperature estimation unit for detecting or estimating the temperature of an ERF and changes the target voltage value on the basis of the value of the temperature estimation unit to adjust piston speed V.
