JP3244465U - Automatic lighting device for automobile and motorcycle headlights - Google Patents

Abstract

[Problem] The headlights of cars and motorcycles are automatically turned on by sensors that detect brightness and darkness, but there is a time lag, and when entering a dark tunnel from a bright daytime road, you cannot see anything in front of you for a moment. Provide a device to ensure visibility. [Solution] Headlights 3 are turned on from before the car 1 enters the tunnel by using a signal that conveys information to the driver in front of the tunnel 2 or railroad crossing by installing a car navigation system using GPS or automatic driving. This is a device that automatically lights up to ensure the driver's visibility when entering a tunnel, and when entering a tunnel etc., the headlights are temporarily turned on brighter than normal at night.

Description

Automatic lighting and output control of headlights of automobiles and motorcycles

Sensors installed on cars and motorcycles automatically turn on the headlights (3) at normal brightness when the car (1) in Figure 1 enters the tunnel (2).

Cars and motorcycles have become more convenient because their headlights are automatically turned on at normal brightness using sensors that detect brightness and darkness. However, the headlights that turn on at the timing shown in Figure 1 do not turn on by the time you enter a pitch-black tunnel during bright daylight, so it cannot be said that it is safer. Additionally, as people get older, their eyesight deteriorates and when entering a dark tunnel, they are unable to see anything in front of them and end up slamming on the brakes without thinking, which can lead to rear-end collisions and traffic jams.

Most modern cars and motorcycles are equipped with car navigation systems that use GPS to provide information to drivers before tunnels and railroad crossings. Using that signal, as shown in Figure 2, headlights 3 are automatically turned on before car 1 enters tunnel 2 to ensure the driver's visibility when entering the tunnel. Also, since it is daytime, the output of the headlights (3) are made brighter than normal at night to ensure visibility immediately after entering the tunnel.

If the headlights (3) are automatically turned on before the car (1) enters the tunnel (2) in Figure 2, it will give the driver peace of mind and prevent rear-end collisions and unnecessary traffic jams. In addition, as people get older, their eyesight deteriorates, so it is better to turn on the headlights (headlights) as bright as possible before the car enters the dark tunnel (2) during the bright daytime to improve visibility and make it safer. be.

4. Direction of travel of the car

Claims (2)

A car navigation system using GPS is installed and uses a signal to convey information to the driver before a tunnel or railroad crossing. A headlight control system that automatically turns on the headlights to ensure the driver's visibility when entering a tunnel. An automatic lighting control system that temporarily turns on the headlights (3) in Figure 3 brighter than usual at night when entering a dark tunnel or the like during bright daytime hours.
