Vehicle position estimation system

Abstract

There is provided a technique for increasing the possibility of being able to prevent deterioration in the accuracy of estimation of a vehicle position. A vehicle position estimation system includes a first error obtaining part that obtains a first error indicating an error in Global Navigation Satellite System (GNSS) information obtained by a vehicle; a second error obtaining part that obtains a second error indicating an autonomous navigation error; a third error obtaining part that obtains a third error indicating an error occurring upon detecting a marking included in an image obtained by photographing a road around the vehicle; and a position estimating part that selects a position estimation method with a smallest error among the first error, the second error, and the third error, and estimates a position of the vehicle in a width direction of the road, using a selected position estimation method.
