Title:
サスペンション制御装置
Document Type and Number:
Japanese Patent JP7058340
Kind Code:
B2
Abstract:
Provided a suspension control apparatus including a vehicle behavior detection unit (acceleration sensors), an electrorheological damper provided between a vehicle body (1) and each wheel (2), and a controller configured to execute control so that a damping force of each electrorheological damper is adjusted based on a detection result obtained by the vehicle behavior detection unit. The controller includes a target voltage value setting unit (damping force command calculation unit) configured to obtain a target voltage value to be applied to an electrode tube based on the detection result obtained by the vehicle behavior detection unit, a temperature estimation unit configured to detect or estimate temperature of ERF, and a target voltage value correction unit (output limiting unit) configured to change the target voltage value so that a piston speed (V) is adjusted based on a value obtained by the temperature estimation unit.
