Latest Patents

Takeyama's latest patents include a velocity estimation device and a travel distance estimation device. The velocity estimation device incorporates an acceleration sensor and a yaw rate sensor to determine the initial velocity of a mobile object. It utilizes a velocity estimation expression that combines the integrated value of acceleration and the relative azimuth derived from detected yaw rates. This device effectively estimates the velocity of the mobile object by constraining the magnitude of the velocity vector and the time variation of its direction.

The travel distance estimation device, on the other hand, is designed to successively estimate the velocity of a movable object based on an integrated acceleration value and an initial velocity. It includes a travel distance calculation unit that continuously calculates the estimated travel distance based on the estimated velocity. Additionally, it features a past velocity correction unit that ensures the continuity of corrected past velocities with the current initial velocity.
