Abstract
Official abstract text for this publication.
This measurement device for measuring the angular velocity or acceleration of a two-wheel vehicle, is provided with a main detection unit which detects the three-axis angular velocity or three-axis acceleration, a support unit which can support the main detection unit on the body of the two-wheel vehicle, and a correction unit which cancels the lean of the body to the left and right in the main detection unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A measurement device that measures an angular velocity or an acceleration of a two-wheel vehicle, the measurement device comprising: a main sensor configured to detect a three-axis angular velocity or a three-axis acceleration; a unit that cancels a tilt of a body of the two-wheel vehicle in a leftward-rightward direction of the body with respect to the main sensor, and does not cancel a tilt of the body in a forward-backward direction of the body with respect to the main sensor, and a beam that is configured to support the main sensor on the body and suspends the main sensor via the unit, wherein the unit comprises a base, a shaft and an arm, the shaft extends from the base in the forward-backward direction, and the arm is configured to oscillate around the shaft as an oscillation axis and suspends the main sensor. 2. The measurement device according to claim 1 , wherein the unit includes a pendulum that makes the main sensor oscillatable in the leftward-rightward direction with respect to the body. 3. The measurement device according to claim 1 , wherein the measurement device includes a damper that damps a vibration from the body, and the beam suspends the main sensor via the damper.
