Vehicle position recognition system
Abstract:
A vehicle position recognition system calculates an estimated position of a vehicle based on satellite positioning and dead reckoning navigation, and calculates a basic error range in which there is a possibility that the vehicle exists. The system calculates an estimated error amount regarding a directional error factor. The directional error factor is an error factor that tends to cause an error in a specific direction with respect to a vehicle traveling direction. The estimated error amount is an estimated amount of the error that is caused by the directional error factor. The system adjusts the basic error range based on (1) a direction in which the error tends to be caused by the directional error factor and (2) the estimated error amount.
