Relative position determining device, relative position determining method, and relative position determining program

Abstract

The objective of the present invention is to provide a relative position determining device, a relative position determining method, and a relative position determining program capable of accurately determining the relative position of a moving body, even if it is unclear whether position information or map information relating to the moving body is accurate. A relative position determining device according to the present invention is provided with: a first trajectory information acquiring unit for acquiring first trajectory information, which is a set of first trajectory points indicating a location through which a first moving body has passed; a second trajectory information acquiring unit for acquiring second trajectory information, which is a set of second trajectory points indicating a location through which a second moving body has passed; a map information acquiring unit for acquiring map information including lane shape information indicating the shapes of lane units; a consistency determining unit for determining whether each of the first trajectory information and the second trajectory information are consistent with the lane shape information; and a relative lane determining unit for determining a relative lane between the first moving body and the second moving body on the basis of the determination result from the consistency determining unit.

Description

technical field [0001] The present invention relates to a relative position judging device, a relative position judging method, and a relative position judging program for judging the relative position of a mobile body in a driving support system using communication. Background technique [0002] In the driving support system using communication, the relative position of the moving body is determined by exchanging position information between the moving bodies, and driving support for improving safety and comfort is provided. Here, the relative position refers to information indicating a relative positional relationship between two mobile bodies. As a determination method of the relative position, there is a method of determining the relative position by associating the mobile object with map information based on the position information of the mobile object. However, such a determination method erroneously determines relative position information when there is an error in ...
