Description

Emergency recognition between vehicles {Emergency cognitive method between vehicles}

The present invention relates to a method for recognizing an emergency situation between vehicles, and more particularly, to a method for recognizing an emergency situation between vehicles, which can notify an adjacent vehicle of an emergency situation of another vehicle or an emergency situation of another vehicle using air waves. It is about.

In general, in the case of a vehicle driving on a highway or a general road, it is very passive to recognize the state of another vehicle adjacent to the distance recognized by the driver's view, that is, through turning or stopping, and to take appropriate measures accordingly. Of course, you have no choice but to use the method.

Improving such a passive method is a method of informing the unspecified number of drivers through the radio of the vehicle by using the air broadcasting to inform the driver of the traffic flow or traffic accident on the road. Of course, there is a limit for not letting other neighboring vehicles know the emergency situation of the vehicle or another vehicle ahead.

Therefore, in a situation where a large number of vehicles are traveling at high speeds, there is an urgent need to develop a method for preventing accidents caused by the unrecognition of an emergency situation occurring in another vehicle ahead of one's own vehicle. Of course.

Therefore, the present invention has been invented in view of the above-mentioned matters, and it is necessary to receive a signal sent from another vehicle in front of an emergency situation based on its own vehicle and take necessary measures as well as an emergency situation recognized by the vehicle. It aims to prevent accidents in advance by transmitting the over-the-air waves to recognize the situation in front of the vehicle behind.

The present invention for achieving the above object, by comparing the vehicle speed difference according to the brake operation of the vehicle to transmit and receive the emergency signal and the measurement signal for the distance difference between the vehicle and the unique number assigned to each vehicle when the conditions are satisfied It is characterized by operating the alarm sound mounted to the driver's seat or the emergency light mounted to the rear of the vehicle to recognize the emergency situation in the vehicle adjacent to the vehicle via the transceiver between the vehicle or the radio base station via the medium.

1 is a flowchart showing a method of recognizing an emergency situation between vehicles according to the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a method for recognizing an emergency situation between vehicles according to the present invention. The present invention compares a vehicle speed difference according to a brake operation of a vehicle and compares an emergency signal with an emergency signal (EBS) when the condition is satisfied. Alarm signal installed in driver's seat to recognize emergency situation in vehicle adjacent to own vehicle through inter-vehicle or radio base station through transmitter / receiver transmitting and receiving measuring signal about distance difference and unique number assigned to each vehicle It will also activate the emergency lights on the rear of the vehicle.

In other words, this will be described in detail based on the vehicle. When the transceiver is started and the vehicle starts, the unique ID ((A1: Identification) of the vehicle is generated by the built-in program and transmitted to the nearest base station. The current vehicle speed V1 is detected.

At this time, the base station receiving the unique ID (A1) continuously transmits the unique ID (A1) transmitted from the vehicle back to the neighboring base station to recognize the unique ID (A1) for each base station, of course.

Subsequently, when the vehicle brakes, the vehicle speed V2 is detected one second after the braking, and when the difference between the current vehicle speed V1 and the vehicle speed V2 after braking has a difference of about 30 km / h, together with the vehicle unique ID A1. Sending an emergency signal (EBS) to the base station, checks the unique ID (A1) that is a signal transmitted from the vehicle to determine the emergency situation according to the emergency signal (EBS) transmission unique ID (A2, transmitted from the vehicle in the relevant area. Check ..

Then, an emergency signal is transmitted along with the unique ID to the area where the other vehicle selected based on the unique ID A1 of the vehicle that has sent the emergency signal EBS is transmitted, and the vehicle in the area of the transmission wave of the base station receives the signal. If it does not match the unique ID (A2) so that the base station signal is ignored, if it matches with the unique ID (A2), if the match with the flashing of the emergency light of the vehicle and generates an alarm sound to recognize the driver.

At this time, in the case of the vehicle that can receive the emergency signal (EBS) transmitted from the stopped vehicle, the emergency light of the vehicle according to the emergency signal flashes and generates an alarm sound to recognize the driver, of course.

On the other hand, the vehicle with a unique ID (A2) receiving a signal from the base station measures the current vehicle speed (V3) to determine whether the distance (L) with the front car at the time of braking can sufficiently secure the safety distance (S) and then enough safety distance. If (S) can be secured, the base station signal is ignored and the driver's judgment is made. If the safety distance S is not sufficient, the brake is urgently activated.

At this time, the braked vehicle detects the vehicle speed V4 after 1 second of braking and does not transmit a signal unless the difference between the current vehicle speed V3 and the vehicle speed V4 after braking does not have a difference of about 30 km / h. If the difference is h, the emergency signal EBS is sent to the base station together with the vehicle unique ID A12.

Then, by checking the unique ID (A2), which is a signal transmitted from the vehicle, it is determined that it is an emergency situation by sending the emergency signal (EBS), and then checks the unique IDs (A3, ... An) sent from the vehicle in the relevant area. In addition, the emergency signal is transmitted along with the unique ID to the area where the other selected vehicle is located around the unique ID A2 of the vehicle that has sent the emergency signal (EBS). If it does not match the unique ID (A3), the base station signal is ignored, if it matches with the unique ID (A3), the emergency light of the vehicle flashes and generates an alarm sound to recognize the driver.

Subsequently, the emergency situation of the front vehicle is notified to adjacent vehicles in this manner.

As described above, according to the present invention, it is necessary to receive a signal sent from another vehicle in front of an emergency situation based on its own vehicle and take necessary measures as well as to transmit the emergency situation recognized by the vehicle by airborne rear. It is effective in preventing unexpected accidents by recognizing the situation ahead of the vehicle.
