Abstract

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.

Claims

1. A vehicle control device comprising:

a display device configured to perform driving assistance to restrain an acceleration of a host vehicle for prompting an occupant of the host vehicle, wherein the display device is configured to provide information to the occupant of the host vehicle;

learned information storage circuitry configured to store a traveling history of the host vehicle;

traveling history learning circuitry configured to store learned information which includes information on deceleration in a to-be-learned zone based on the traveling history of the host vehicle in the learned information storage circuitry in association with a position of the to-be-learned zone and with a traveling direction of the vehicle in the to-be-learned zone, the to-be-learned zone has a predetermined distance to an objective point, with objective points being set at a plurality of points of a road;

learned information obtaining circuitry configured to obtain, from the learned information storage circuitry, learned information corresponding to a position of the host vehicle; and

a display control circuitry configured to display, on the display device, a learning status display showing a learning status determined from the learned information based on the information on deceleration in the to-be-learned zone, the learning status showing a learning progress of the to-be-learned zone, corresponding to the traveling direction of the host vehicle.

2. The vehicle control device according to claim 1, wherein the display control circuitry is configured to display, on the display device, only the learning status display showing the learning status corresponding to the traveling direction of the host vehicle.

3. The vehicle control device according to claim 1, wherein the display control circuitry is configured to display, on the display device, the learning status display corresponding to the traveling direction of the host vehicle in a display manner different from learning status displays showing learning statuses corresponding to other different traveling directions.

4. The vehicle control device according to claim 1, further comprising a learning status determination circuitry configured to determine a learning status of the to-be-learned zone based on the obtained learned information, wherein

the learning status determination circuitry is configured to calculate a frequency of a predetermined traveling state in the to-be-learned zone by use of learned information corresponding to the position and the traveling direction of the host vehicle and to determine learning progress based on the frequency, and

the display control circuitry is configured to display the learning status display corresponding to the traveling direction of the host vehicle when the determined learning progress has reached predetermined progress.

5. The vehicle control device according to claim 1, further comprising a route search circuitry configured to search for a route from a departure place to a destination, wherein

the learned information obtaining circuitry is configured to obtain learned information on a searched route and in a traveling direction from the departure place toward the destination, and

the display control circuitry is configured to display, on the display device, the learning status display of the route retrieved based on the obtained learned information.

6. The vehicle control device according to claim 1, wherein the display control circuitry is configured to display the learning status display corresponding to the traveling direction of the host vehicle under at least one of the condition that i) the host vehicle has entered the to-be-learned zone and the condition that ii) a relative distance between the position of the host vehicle and the to-be-learned zone has become equal to or less than a predetermined distance.

7. The vehicle control device according to claim 1, wherein the display control circuitry is configured to bring the learning status display into a non-display state under the condition that the host vehicle has left the to-be-learned zone.
