A traveling history learning section circuitry stores learning information based on the traveling history of the vehicle in association with the position of a to-be-learned zone and with the traveling direction of the vehicle in the to-be-learned zone. A learning information obtaining section circuitry obtains learning information corresponding to the position of a host vehicle from the learning information storage section. A display control section circuitry displays a learning status display showing a learning status corresponding to a traveling direction of a host vehicle.
