Description

Brake light inoperative detection system

The present invention relates to a system for detecting a non-operation of a brake light, and more specifically, analyzing a captured image of a rear of a preceding vehicle to determine whether a brake light of the preceding vehicle has failed, and notifying the preceding vehicle when the brake light is not operating. It relates to a brake malfunction detection system that transmits a message.

In general, a brake light of a vehicle is a signal equalizing device for informing a driver of another vehicle of a driving state of a driving vehicle such as a turn signal or an emergency light. When the driver presses the brake pedal or pulls the hand brake when braking, the state of the brake switch or hand brake switch is switched to the on state.

When the state of the brake switch or the hand brake switch is switched to the on state, the brake lights mounted on the left and right rear portions of the vehicle are turned on to inform the driver of the following vehicle that the vehicle is braking.

However, if the brake light is disconnected and the vehicle is braking, but the brake light is not lit, there is a problem that a collision accident occurs when a driver of another vehicle that follows is unable to recognize that the vehicle in front is braking.
