1. A vehicle position detection device comprising:
a computer configured with a non-transitory computer-readable medium and configured to carry out processing to perform operations comprising:
receiving a satellite positioning position signal of a vehicle and calculating a satellite positioning position of the vehicle;
receiving an autonomous navigation position signal of the vehicle and calculating an autonomous navigation position of the vehicle;
calculating a positional difference between the satellite positioning position and the autonomous navigation position;
storing a plurality of parameter sets in which a plurality of thresholds for allowing the positional difference for each speed of the vehicle are set per vehicle characteristic;
selecting a parameter set corresponding to the vehicle characteristic from the plurality of stored parameter sets; and
outputting the satellite positioning position when the positional difference is within a threshold, and outputting the autonomous navigation position when the positional difference is out of the threshold.
