A first measuring device measures a location of its own vehicle relative to each feature point on a surrounding structure around a road surface on which the vehicle. A first feature-point is provided which, based on output from the first measuring device, acquires coordinates of the each feature point expressed in a coordinate system of the first measuring device, and uses a self-location to convert the coordinates into an external coordinate. A feature-point trajectory generation section is provided to generate, based on the first coordinates, a trajectory of the feature point group. A second measuring device measures a location of its own vehicle relative to a feature point located rearward of the feature point measured by the first measuring device. An anomaly determination section is provided to determine that anomaly occurs in a self-location estimation device if the second coordinates are on the trajectory.

The invention is intended to be able to generate map data even if a location not suited for identification of a matching position exists. A map data creation device creates map data, the map data being used for autonomous movement by a vehicle (), a vehicle () and/or other vehicles (), based on a relative position of the vehicle () which exists around the vehicle (), relative to the vehicle (), the relative position being measured by the vehicle (), and object shape data of an object which exists around the vehicle (), the object shape being measured by the vehicle (). Moreover, the relative position of the vehicle () relative to the vehicle () is calculated based on the object shape data measured by the vehicle ().
