Abstract: A self-localization estimation unit of a self-localization estimation device determines, based on mutual relationships between the in-lane position and the absolute position including the error, whether there is lane-relevant candidate information, the lane-relevant candidate information representing that one or more in-vehicle positions are each estimated to be in which of lanes identified by the lane information; and estimates, based on a result of the determination of whether there is lane-relevant candidate information, a localization of the own vehicle corresponding to the map information.

Abstract: An abnormality is detected in a sensor system mounted on a vehicle and including first and second external sensors for acquiring external information and an internal sensor for acquiring internal information. An error, occurring in an internal motion physical quantity based on the internal information, is estimated based on the external information, and the error is corrected. A first external motion physical quantity based on the external information acquired by the first external sensor, a second external motion physical quantity based on the external information acquired by the second external sensor, and the internal motion physical quantity in which the error is corrected by the correction block are compared to determine an abnormality in the sensor system.

Abstract: A self-localization estimation device includes: a map-information acquisition unit that acquires map information including lane information for specifying lanes in which vehicles are enabled to travel; a position calculation unit that calculates an own-vehicle absolute position being an absolute position of an own vehicle in response to navigation signals received from a plurality of navigation satellites, the position calculation unit including a self-location measurement unit, a vehicle-momentum measurement unit, and dead reckoning unit; and a position estimation unit that estimates, based on the map information and the own-vehicle absolute position, a corrected own-vehicle position being a corrected position of the own vehicle. The position estimation unit estimates the corrected own-vehicle position by superimposing a reliability of the map information and a reliability of the own-vehicle absolute position on each other.
