A vehicle position detection device includes: a satellite positioning position calculation unit that receives a satellite positioning position signal of a vehicle and calculates a satellite positioning position of the vehicle; an autonomous navigation position calculation unit that receives an autonomous navigation position signal of the vehicle and calculates an autonomous navigation position of the vehicle; a distance calculation unit that 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 unit that selects a parameter set according to the vehicle characteristic from a plurality of parameter sets to stored in the recording unit; and a determination unit that 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.",
