TW202227297A - Safe driving distance indicator - Google Patents

Abstract

The invention is applied to the vehicle when it is in motion. Can illuminate the road with lights according to different driving speeds. Shows the safe distance that should be maintained at the current rate. The invention is installed in front of the vehicle. It can remind the driver of the safe distance to keep at different speeds. If the present invention is installed behind the vehicle. Then remind the driver behind to keep a safe distance from the vehicle. Failure to maintain a safe driving distance is an important factor in car accidents. Especially in serial chase accidents

Description

safe distance indicator

The present invention is a safety device, when installed in front of the mobile device, it will prompt the safe distance that should be kept when driving according to different driving speeds. It can also be installed at the back of the mobile device to remind the rear driver to keep a safe distance. Force the light system to stop working when the driving speed is too low or the vehicle rolls over.

The present invention can be installed on any mobile device, such as automobiles, motorcycles, bicycles, rail vehicles, etc., and uses lights to illuminate the road surface to show the safe distance that should be maintained at the current speed. When the speed is changed, the light exposure distance will also change to meet the most appropriate safety distance to maintain at any driving speed.

The device of the present invention is in front of or behind the mobile device, and when installed in the front, it can remind the driver to keep a safe distance in front; when installed in the rear, it can remind the driver behind the driver to keep a safe distance.

The lighting system of the device of the present invention can use spotlight or laser light or other light sources. For example, the use of green lasers makes it possible to indicate clearly during the day. The laser light is only irradiated on the road, so as to avoid light pollution on other drivers.

The device of the present invention can install an LED sign at the rear of the mobile device, and at the same time as the system Action, let the rear driver understand the purpose of illuminating the light.

The device of the present invention is set to stop operating at a rate below 20 miles/hour to save power and reduce light interference.

The device of the present invention is provided with a sensing device for forcing the light system to stop working after the vehicle rolls over, so as to avoid the strong light irradiating people after the accident and causing other injuries.

The device of the present invention uses the traveling speed sensor to send a signal to the controller, and the controller activates the lighting system and the stepping motor for changing the lighting angle respectively according to the current situation, so that the lights illuminate different safe distances according to different traveling speeds. An LED sign is installed at the rear and the system operates at the same time, so that the drivers behind can understand the purpose of illuminating the light. And set up a perception device that directly forces the lighting system to stop working after the car rolls over.

Claims (5)

A safety device utilizes a lighting system with the following functions: The road surface can be illuminated according to the driving speed of various mobile devices, and the safe driving distance that should be maintained at the current speed can be illuminated. The light source of the lighting system as claimed in claim 1 can be any visible light. For example, spotlights, red lasers, blue lasers, green lasers, , , etc. As claimed in item 2, the lighting system can be installed on any mobile device, such as automobiles, motorcycles, bicycles, rail vehicles, , , etc. devices. If the lighting system of claim 3 is installed in front of the mobile device, it will remind the driver of the safety distance that should be maintained in front of the current speed. For example, request item 3, the lighting system can also be installed behind the mobile device to remind the drivers behind the safe distance that should be kept at the speed at that time, and LED signs are added to let the drivers behind them understand the purpose of illuminating the light.
