Damper control device
First Claim
1. A damper control device comprising:
- a pitching angular velocity detection unit configured to detect a pitching angular velocity of a vehicle body of a two-wheeled vehicle;
a roll angle detection unit configured to detect a roll angle of the vehicle body;
a yaw angular velocity detection unit configured to detect a yaw angular velocity of the vehicle body;
a front-wheel side pressure detection unit configured to detect a pressure of a contraction-side chamber in a front-wheel side damper, the front-wheel side damper being interposed between the vehicle body and a front-wheel of the two-wheeled vehicle;
a rear-wheel side pressure detection unit configured to detect a pressure of a contraction-side chamber in a rear-wheel side damper, the rear-wheel side damper being interposed between the vehicle body and a rear-wheel of the two-wheeled vehicle; and
a correction unit configured to correct the pitching angular velocity on the basis of the roll angle and the yaw angular velocity, the correction unit being configured to remove a component based on the roll angle and the yaw angular velocity from the detected pitching angular velocity during turning of the two-wheeled vehicle, whereinthe pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber in the rear-wheel side damper are controlled on the basis of the corrected pitching angular velocity, the pressure of the contraction-side chamber in the front-wheel side damper, and the pressure of the contraction-side chamber in the rear-wheel side damper.

Abstract
The damper control device includes a three axis rate sensor that detects a pitching angular velocity of a vehicle body of a two-wheeled vehicle, a pressure sensor that detects a pressure of a contraction-side chamber in a front-wheel side damper, a pressure sensor that detects a pressure of a contraction-side chamber of a rear-wheel side damper, and a correction unit that corrects the pitching angular velocity. The damper control device controls the pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber of the rear-wheel side damper on the basis of the corrected pitching angular velocity, the pressure of the contraction-side chamber in the front-wheel side damper and the pressure of the contraction-side chamber of the rear-wheel side damper.
