Vehicular navigation system

摘要

A vehicle unit in a vehicle determines whether the driver has encountered a difficult spot, which is difficult to understand, based on the deviation from a route, the behavior of the vehicle, and the behavior of the driver. A standard for determining the difficult spot can be corrected by learning. The vehicle unit acquires a raw image picked up at the difficult spot. The raw image is used to verify the determination of the difficult spot. The vehicle unit transmits the raw image to a center unit in a distribution center. The center unit creates a clean image based on a plurality of raw images transmitted from a plurality of vehicles. The clean image that does not show moving objects such as pedestrians and other vehicles is distributed to a succeeding vehicle arriving at the difficult spot. The vehicle unit displays the distributed clean image as a guidance image.

主权项

1. A vehicular navigation system comprising:
a determination section that determines a difficult road fork from among a plurality of road forks on a road based on at least one behavior of (i) a behavior of a vehicle and (ii) a behavior of a driver of the vehicle, the difficult road fork being a road fork that hinders the driver from properly understanding a structure of a course of the road fork; and a supply section that, based on a raw image picked up at the difficult road fork, supplies an image for providing assistance in driving at the difficult road fork, the supply section including a creation section that creates a clean image by erasing at least partially a moving object that includes a pedestrian or another vehicle, from the raw image, the vehicular navigation system further comprising:
a plurality of vehicle units disposed respectively in a plurality of vehicles; anda center unit communicably connected to the plurality of vehicle units, wherein: the vehicle unit includes
a camera that supplies the raw image by picking up an image of an area in front of the vehicle where the vehicle unit is mounted,the determination section, anda transmission section that transmits the raw image to the center unit; the center unit includes
a center reception section that receives the raw image transmitted from the transmission section,the creation section, anda distribution section that distributes the clean image to the vehicle units; the vehicle unit further includes
a vehicle reception section that receives the clean image distributed from the distribution section and stores the clean image in a storage unit, anda display section that causes a display to display the clean image stored in the storage unit when the difficult road fork is encountered; and the supply section is implemented by the creation section, the distribution section, the vehicle reception section, and the display section.
