<p>To acquire a direction error of a vehicle so that a more appropriate result is acquired in subsequent processing, a vehicle position detection device includes: a start/end point calculation part for acquiring a turning start point on a pre-turning link, and acquiring a turning end point on a post-turning link; a virtual link generation part for acquiring a virtual link connecting between the turning start point and the turning end point; a link direction calculation part for calculating a virtual link direction that is a direction at a predetermined position on the virtual link; and an error calculation part for using the virtual link direction to calculate a direction error of a vehicle direction.</p> |
