Title:
移動距離推定装置
Document Type and Number:
Japanese Patent JP6409346
Kind Code:
B2
Abstract:
A travel distance estimation device is provided. The travel distance estimation device includes an estimated velocity determination unit that successively estimates an estimated velocity of a movable object based on an acceleration integrated value and a velocity initial value a travel distance calculation unit that successively calculates an estimated travel distance of the movable object based on the estimated velocity, and a past velocity correction unit that determines corrected past velocities by correcting pre-correction past estimated velocities so that the corrected past velocities are continuous with the velocity initial value determined this time. The pre-corrected past estimated velocities are the estimated velocities that were successively determined. The travel distance estimation device further includes a travel distance correction unit that recalculates based on the corrected past velocities an estimated travel distance.
