Vehicle operation supporting device and vehicle operation supporting system
First Claim
1. A vehicle operation supporting device comprising:
- a beam radiating portion that intermittently radiates light beams having a predetermined optical characteristic onto a road surface around a vehicle, the light beams being laser beams; and
a dimming portion that intermittently becomes less permeable to light having the predetermined optical characteristic than to light having optical characteristics other than the predetermined optical characteristic in synchronization with radiation of the light beams from the beam radiating portion.

Abstract
A beam radiator that radiates visible light beams having a predetermined wavelength onto a road surface to inform drivers of other vehicles of the existence of a self-owned vehicle or to let a driver of the self-owned vehicle confirm a traveling path thereof is disposed in a front portion of a body of the self-owned vehicle. An optical filter is disposed substantially all over a windshield in front of a driver seat. The filter is designed to have a characteristic of being more permeable to light having wavelengths close to a wavelength of visible light beams radiated from the beam radiator 24 than to light having a wavelength different from those wavelengths. In this construction, the driver is prevented from finding it difficult to visually recognize a visible light pattern resulting from visible light beams radiated from the self-owned vehicle or another vehicle owing to sunlight or the like, and visual recognizability of the visible light pattern is enhanced.
