SUSPENSION CONTROL APPARATUS

摘要

Provided is a suspension control apparatus which is capable of suppressing changes in damping force characteristics caused by changes in the temperature of electrorheological fluid. This suspension control apparatus is equipped with a vehicle behavior detection unit, a damping force adjustable shock absorber, and a controller. The damping force adjustable shock absorber is equipped with: a cylinder in which electrorheological fluid is sealed; a piston which is slidably inserted in the cylinder; a piston rod which is coupled to the piston and extends to the exterior of the cylinder; and an electrode which is provided to a portion where the flow of the electrorheological fluid is generated by the sliding of the piston within the cylinder, and applies an electrical field to the electrorheological fluid. The controller is equipped with: a target voltage value setting unit which obtains a target voltage value to be applied to the electrode on the basis of the detection result of the vehicle behavior detection unit; a current detection unit which detects a current value when the target voltage value obtained by the target voltage value setting unit is applied; and a voltage value correction unit which corrects the target voltage value on the basis of the detection current value detected by the current detection unit or a function of the detection current value.
