Abstract

A system and method for preventing traffic signal violation using infrared communication is provided. The system includes a traffic light controlling system for, when a traffic light changes, transmitting traffic information; a brake system for decelerating or stopping a vehicle under a predetermined control; and a traffic signal violation prevention device installed at the vehicle, and receiving the traffic information and, if the traffic information is stop signal information, transmitting a stop signal to the brake system.

Claims

1. A system for preventing traffic signal violation using infrared communication, the system comprising:

a traffic light controlling system for, when a traffic light changes, transmitting traffic information;

a brake system for decelerating or stopping a vehicle under a predetermined control; and

a traffic signal violation prevention device installed at the vehicle, and receiving the traffic information and, if the traffic information is stop signal information, transmitting a stop signal to the brake system,

wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system.

2. The system according to claim 1, wherein the traffic light controlling system comprises:

a timer for counting a time;

a traffic light having a plurality of lights representing whether or not to run the vehicle, and turning on/off under a predetermined control;

a controller for controlling sequential lighting of the traffic lights depending on the counted time and, when the lighted light changes, generating the traffic information; and

an infrared transmitter for loading and transmitting the traffic information on an infrared frequency.

3. The system according to claim 1, wherein the traffic signal violation prevention device detects a speed of the vehicle and, when the detected speed is less than a previously set speed, transmits the stop signal to the brake system.

4. The system according to claim 3, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system.

5. A method for preventing traffic signal violation using infrared communication, the method comprising the steps of:

when a traffic light changes, transmitting traffic information in a traffic light controlling system;

in a traffic signal violation prevention device, receiving the traffic information and, when the traffic information is stop signal information, generating and transmitting a stop signal; and

in a brake system, receiving the stop signal to decelerate or stop a vehicle,

wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system.

6. The method according to claim 5, wherein the traffic signal violation prevention device detects a speed of the vehicle and, when the detected speed is less than a previously set speed, transmits the stop signal to the brake system.

7. The method according to claim 6, wherein the traffic signal violation prevention device has a distance measurement unit for measuring a distance from another vehicle positioned in rear of the vehicle and, when the measured distance from another vehicle is greater than a predetermined distance, transmits the stop signal to the brake system.
