Suspension control apparatus

摘要

A suspension control apparatus includes a damping force adjustable shock absorber disposed between a vehicle body and a wheel of a vehicle and capable of adjusting a damping force to be generated, a vertical movement detection device configured to detect a state regarding a vertical movement of a vehicle, and a controller including: a target damping force calculation section configured to calculate a target damping force based on a detection result of the vertical movement detection device, a correction section configured to calculate a corrected damping force, which is acquired by reducing the target damping force when a relative speed is a low speed between a sprung side and an unsprung side of the damping force adjustable shock absorber, and a control signal output section configured to output the control signal corresponding to the corrected damping force to the damping force adjustable shock absorber.

1. A suspension control apparatus comprising:
a damping force adjustable shock absorber disposed between a sprung side and an unsprung side of a vehicle and capable of adjusting a damping force to be generated; a vertical movement detection device configured to detect a state regarding a vertical movement of the vehicle; and a controller configured to output a control signal for controlling the damping force to be generated by the damping force adjustable shock absorber based on a detection result of the vertical movement detection device, wherein the controller is configured to:
calculate a target damping force based on a detection result of the vertical movement detection device,calculate a corrected damping force, which is smaller than an absolute value of the target damping force, when a relative speed between the sprung side and the unsprung side of the vehicle is a low speed, an absolute value of the corrected damping force increasing as the relative speed increases, an inclination of the corrected damping force to the relative speed being smaller when the relative speed is in a first speed region, the inclination of the corrected damping force to the relative speed being larger than in the first speed region when the relative speed is in a second speed region higher than the first speed region, andoutput the control signal corresponding to the corrected damping force to the damping force adjustable shock absorber, when the absolute value of the calculated corrected damping force is smaller than the absolute value of the calculated target damping force.
