開示された発明のひとつは、車両の挙動、および／または運転者の挙動と基準との比較に基づいて、運転者が道路構造または進路を理解することが困難な道路上の難解地点を判定する判定部（１３１、１５４、１５５）と、難解地点において観測された車両の挙動、および／または運転者の挙動に基づいて、基準を修正する学習部（１３５）と、難解地点において撮影された原画像（ＲＶ１、ＲＶ２）に基づいて、難解地点における運転を支援するための画像（ＣＶ、ＮＶ）を提供する提供部（１３２−１３４、１４１−１４５、１３６−１３７）とを備え、提供部は、原画像から他の車両および／または歩行者などの移動体の少なくとも一部を消去したクリーン画像（ＣＶ）を作成する作成部（１４４）を含む車両用ナビゲーションシステムにおいて、複数の車両（４）のそれぞれに設けられた複数の車両装置（５）と、複数の車両装置と通信可能に接続されたセンタ装置（３）とを備え、車両装置（５）は、車両の前方を撮影することにより原画像を供給するカメラ（５ｄ）と、判定部と、原画像を車両装置からセンタ装置へ送信する送信部（１３４）とを備え、センタ装置（３）は、送信部から送信された原画像を受信するセンタ受信部（１４１）と、作成部と、クリーン画像を車両装置に配信する配信部（１４５）とを備え、車両装置（５）は、さらに、配信部から配信されたクリーン画像を受信し記憶装置（５ｂ）に記憶する車両受信部（１３６）と、難解地点を走行するときに記憶装置に記憶されたクリーン画像を表示器（５ｅ）に表示する表示部（１３７）とを備え、作成部と配信部と車両受信部と表示部とにより提供部が提供されていることを特徴とする。 One of the disclosed inventions determines difficult points on the road where it is difficult for the driver to understand the road structure or course based on vehicle behavior and / or comparison of driver behavior with criteria. Based on the determination unit (131, 154, 155), the behavior of the vehicle observed at the difficult point and / or the behavior of the driver, the learning unit (135) for correcting the reference, and the original imaged at the difficult point based on the image (RV1, RV2), and a providing unit (132-134,141-145,136-137) to provide an image for supporting operation in difficult locations (CV, NV), the providing unit A vehicle navigation system including a creation unit (144) that creates a clean image (CV) in which at least a part of another vehicle and / or a moving body such as a pedestrian is deleted from the original image The vehicle device (5) includes a plurality of vehicle devices (5) provided in each of the plurality of vehicles (4), and a center device (3) connected to the plurality of vehicle devices in a communicable manner. The center device (3) includes a camera (5d) that supplies an original image by photographing the front of the vehicle, a determination unit, and a transmission unit (134) that transmits the original image from the vehicle device to the center device. The vehicle device (5) further includes a center reception unit (141) that receives the original image transmitted from the transmission unit, a creation unit, and a distribution unit (145) that distributes the clean image to the vehicle device. The vehicle receiving unit (136) that receives the clean image distributed from the unit and stores it in the storage device (5b), and the clean image stored in the storage device when traveling through the difficult point is displayed on the display (5e). A display unit (137) Providing unit is characterized that you have been provided by the display unit and the creating unit and the distribution unit and the vehicle receiver.
