Abstract:
The vehicle position estimation device includes a processor configured to estimate a vertical position of a vehicle based on an output of a vehicle state detection device, detect actual dividing lines at both left and right sides of the vehicle, compare a dividing line on a map at the vertical position of the vehicle and an actual dividing line and estimate a horizontal position of the vehicle, and determine a driving route of the vehicle. The processor is configured to calculate an amount of change of a horizontal position with respect to the driving route based on a map information for each of dividing lines of both left and right sides of the driving route in a predetermined range, and determine a dividing line on the map for comparison based on the amounts of change.
