Travel information providing device
First Claim
1. A traveling information providing apparatus comprising:
- a peripheral information collector that acquires peripheral information indicating a peripheral situation of a vehicle equipped with said traveling information providing apparatus;
an object extractor that extracts a safety confirmation object, which is an object of safety confirmation performed by a driver of the vehicle, from the peripheral information acquired by said peripheral information collector;
a line-of-sight detector that detects a line-of-sight direction in which the driver is looking;
a visibility calculator that, using the extracted safety confirmation object and the detected driver'"'"'s line-of-sight direction, calculates a numerical value of visibility, taking into consideration peripheral vision of the driver, with respect to the safety confirmation object according to a distance or angle from the driver'"'"'s line-of-sight direction to the safety confirmation object; and
a controller that performs evocation of safety confirmation or control of a vehicle'"'"'s driving state based on the calculated numerical value of visibility,wherein when the safety confirmation object is in a peripheral visual field of the driver, said visibility calculator calculates the numerical value of the visibility as a value between zero and a value calculated when the safety confirmation object is located in a central visual field, the numerical value of the visibility calculated for the safety confirmation object in the peripheral visual field being different from either zero or the value calculated when the safety confirmation object is located in the central visual field.

Abstract
A traveling information providing device is provided in which a surrounding information corrector acquires surrounding information on the condition surrounding a vehicle equipped with the device. An object extractor extracts a safety confirmation object the safety of which must be confirmed by a driver from the surrounding information acquired by the surrounding information collector. A line-of-sight detector detects a line-of-sight direction of the driver. A visibility calculator receives the extracted safety confirmation object and the line-of-sight direction of the driver and calculates visibility in consideration of the driver'"'"'s peripheral vision with respect to the safety confirmation object according to the distance or the angle from the driver'"'"'s line-of-sight direction to the object. An information presenter presents safety confirmation to the driver depending on the calculated visibility.
