Abstract
It is possible to reduce inadvertent vehicle behavior during autonomous driving. A vehicle position detection device includes: a satellite positioning position calculation unitthat receives a satellite positioning position signal of a vehicle and calculates a satellite positioning position of the vehicle; an autonomous navigation position calculation unitthat receives an autonomous navigation position signal of the vehicle and calculates an autonomous navigation position of the vehicle; a distance calculation unitthat calculates a positional difference between the satellite positioning position and the autonomous navigation position; a recording unit that stores a plurality of parameter sets in which a plurality of thresholds for allowing a positional difference for each speed of the vehicle are set per vehicle characteristic; a selection unitthat selects a parameter set according to the vehicle characteristic from a plurality of parameter setstostored in the recording unit; and a determination unitthat outputs the satellite positioning position when the positional difference is within the threshold, and outputs the autonomous navigation position when the positional difference is out of the threshold.
