JPH02231245A - Advance path forecasting device utilizing light beam for automobile - Google Patents

Abstract

PURPOSE:To permit the easy and safe drive of an automobile by installing a light irradiating device onto a car body and irradiating light beam towards a road surface from a car body and forming a light mark which represents the advance path which is expected as the course of the car body. CONSTITUTION:A light irradiating device 2 for laser, etc., is installed onto the car body 1 of an automobile, etc. The light beam 3 is irradiated towards a road surface in front of the car body 1 from the light irradiating device 2. Then, a light mark is formed on an advance path 4 which is expected as the course of the car body 1. For instance, when the automobile travels on a curve, the advance path 4 of the car body 1 is easily expected on the basis of the steering angle of a wheel. Therefore, when the automobile travels on a curve, the irradiation angle of the light 3 is interlocked with the steering angle of the wheel, and the light mark is formed along the expected advance path 4 of the car body 1. Therefore, even an unexperienced driver who has the insufficient car width feeling can be easily drive the automobile, and the approach of the own vehicle is informed to the environment more speedily.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a technology that aids safe driving of an automobile.

(Purpose of the Invention) In conventional automobiles, it takes F
required lII. This makes it difficult and dangerous for beginners and those with limited skill to drive on narrow roads, avoid telephone poles, pedestrians, vehicles in ponds, etc., or park on the side of the road.

In addition, the risk of a collision increases when a low-noise vehicle drives on a road with poor visibility without its lights on. This invention aims to reduce these difficulties and risks. (Yokohama of the invention) As shown in FIG.
This device is characterized by the fact that an irradiation device is attached and a beam of light directed from the vehicle body toward the road surface creates a light mark indicating the course the vehicle body is expected to take. Once the angle of the wheels is determined based on the curve of the car, it is easy to predict the course the car will take using a computer. Therefore, when making a curve, by linking the emission angle of the light beam to the angle of the wheels, as shown in Figure 2, it is possible to make the light mark on the road surface follow the outer edge of the path the vehicle will pass. Become.

The light beam #lI#tvIrI1 may be equivalent to what is widely realized today in lasers for concert effects, laser art, etc., and these also commonly realize techniques to freely change the angle of the light beam. ing. Il for the rays! ! ! It is desirable to have a color that makes it easy to use, and an output that allows the light marks created when the light beam hits the road surface to be visible to the naked eye even during the day. (Effects of the Invention) With a car that implements this invention, even a driver who does not have sufficient sense of the vehicle can drive on narrow roads and avoid collisions with electric IJI poles, pedestrians, etc.
It can reduce the difficulty and danger of driving while avoiding other vehicles or parking close to the side of the road. A car that implements this invention can notify its surroundings a little earlier of its approach through light marks on the road surface, which can reduce the risk of an accident caused by an encounter with a rabbit. Note that the effect of the light markings on the road will be even greater if the markings are placed farther away from the vehicle body when driving at high speeds.
