Description

  The present invention is characterized by avoiding danger in advance by communicating as an emergency radio signal in the same frequency radio wave band between a plurality of vehicles equipped with the same radio equipment capable of transmitting and receiving. The present invention relates to a radio wave hazard lamp that is effective in a vehicle, etc.

Almost all alarm devices for vehicles used in the past are of complicated technology using high technology. However, when these vehicle alarms are actually installed, the product becomes quite expensive. Accidents can be reduced by installing equipment that combines high-tech technology with low price and high functionality in many vehicles and communicating with emergency radio signals. This function is speedy advance notification by radio waves. It is an emergency signal reception from the unrecognized field and an emergency signal transmission to the unrecognized field. If the vehicle is out of order or has a single accident, it is unreasonable since the opening of the expressway. In this way, dangerous countermeasures will be improved.
Conventionally, only a vehicle located near the tail of a traffic jam can easily create a warning light situation, and for the driver of a subsequent vehicle approaching the tail of the traffic jam, the position of the tail of the traffic jam is easy. Patent Document 1 discloses a warning light control device and method capable of providing an environment for making a judgment

JP 2006-44447 A

The specific configuration of the warning light control device described in the above-mentioned Patent Document 1 is the warning light control device that controls the start and stop of blinking of the warning light of the host vehicle that presents a warning to other surrounding vehicles. The narrow area communication means for performing narrow area communication with other existing vehicles, and the narrow area communication means to transmit a radio wave including blinking state information indicating whether or not the warning light of the own vehicle blinks. The blinking state information received from the vehicle by the narrow area communication means is used to start blinking the warning light of the host vehicle, and then count the number of the other vehicles that have started blinking the warning light. And control means for stopping blinking of the warning light of the host vehicle based on the number of vehicles.
However, in the above-described configuration, after the warning light of the own vehicle starts blinking, the number of other vehicles that have started blinking the warning light is counted, and the control for stopping the blinking of the warning light of the own vehicle based on the number is performed. Means must be provided, the structure becomes complicated, malfunctions easily occur, and the apparatus itself is expensive.

  Therefore, in the present invention, a plurality of devices having functions of transmitting and receiving in the same radio frequency band are intended for the purpose of simplifying the device configuration, causing no malfunction, and being able to be manufactured at low cost. Provided is a radio wave hazard lamp inter-vehicle communication radio wave device characterized in that it is installed in a vehicle, communicates an emergency signal, and avoids danger in advance.

  Radio wave hazard lamp inter-vehicle communication radio equipment characterized by installing emergency radio signals in the same frequency band by installing equipment with radio transmission / reception functions in multiple vehicles. In order to prevent traffic accidents due to rear-end collisions, multiple accidents, and accidents, the system is installed in more vehicles and alerts ahead of the danger ahead.

The present invention is configured as described above and has the following effects.
(1) By installing the above equipment in multiple vehicles and communicating emergency radio signals at the same frequency, emergency notifications using radio waves, such as emergency stops due to accidents or breakdowns, the end of traffic jams, lane restrictions due to construction, etc. By this, a forward crisis can be recognized in advance. In recent years, as a dangerous work that is one of the causes of people hitting on the highway, there is a possibility that the countermeasures from the time of opening the highway, such as triangle display board, flame tube, evacuation outside the guard rail, etc. can be changed Rise. The reason why it is dangerous is that there is a law that people should not walk on the highway when installing the above-mentioned display board, and it is questionable how to install it. If it is bounced, for example, according to the calculation standard of Japan Highway Safety Institute, it is the responsibility of the person walking at a ratio of 9: 1. In addition, mountainous highways have many tunnels and viaducts, and the outside of the guardrail is a cliff, even if passengers are disabled, elderly, infants, bad weather like typhoons, You must follow the rules. In addition, it is unlikely that JAF will be able to arrive in the meantime for the flame tube, which is limited to 5 minutes, and in the case of a serious accident, passengers must evacuate and have to arrange another means of transportation. It will take a long time. As described above, it is a means for safely performing the rules revision, the necessity of prior notification for preventing a rear-end collision multiple accident, and the accident handling and lane regulation work.
(2) A single accident or a broken vehicle leads to multiple accidents until the road is closed. This is because there was no equipment that could handle the mechanism of multiple accidents on a straight road. The mechanism is that when there is an emergency stop failure vehicle 1 ahead of the large vehicle 2, the large vehicle 2 suddenly changes lanes, and the failure vehicle 1 suddenly appears in front of the follower vehicle 3 in time to stop. This is a phenomenon that causes a rear-end collision. Further, when the following vehicle 3 is a right steering wheel, the discovery is further delayed. In this case, the problem does not occur if the stopped vehicle 1 performs advance notification by radio waves. In addition to this mechanism, the rear-end collision of the following vehicle 5 to the stop vehicle 4 at the curve destination is the same. Unless there is a countermeasure for the above mechanism, multiple accidents will occur.
(3) The above mechanism occurs on a road capable of high speed travel, and it is difficult to cope with a vehicle equipped with a millimeter wave radar, a monocular camera, or a binocular camera.
(4) In the event of an accident or failure in the vehicle of (3), conventional countermeasures such as a triangular display plate and a flame tube must be taken.
The embodiments of the present invention have been described with reference to the drawings.

It is a mechanism diagram in which a rear-end collision occurs on a straight road or curve. It is a radio wave arrival visual field distance and a hazard lamp switch interlocking figure.

The radio wave hazard lamp inter-vehicle communication radio wave device (hereinafter sometimes simply referred to as “device”) 8 according to the present invention is a device capable of transmitting and receiving by radio wave communication.
By connecting the normal standard hazard lamp switch 7 and the device 8 with a signal cable and pressing the hazard lamp switch 7, radio waves are transmitted. While the hazard lamp is lit, radio waves continue to be transmitted. In addition, the hazard lamp can be turned on and radio waves can be transmitted simultaneously.
The radio wave arrival visual field distance 6 is estimated to have a radius of about 500 m centering on the transmitting vehicle. The experiment can be set to increase or decrease the distance. It does not have directivity, and 360 degrees are notified to the installation vehicle of the device 8 as a danger area within the radio wave reachable range.
In the case of one lane on one side of a general road, if there is a failure, accident vehicle, or parked vehicle, the center line must be crossed, so an emergency signal is sent to all vehicles that are facing the calling vehicle. Don't dare have sex. In addition, since mischief and other measures are linked to the hazard lamp, it is impossible to run while it is lit, even if the hazard lamp is lit when stopped, the original purpose of the radio wave hazard lamp itself, It is a reminder, paying attention to the speed when the speed is exceeded, and keeping a sufficient distance when the distance between the vehicles is short.
The display of the device 8 is an alarm sound and an alarm lamp. When a radio wave is received, a warning sound is heard once with a beeping sound. During reception of a radio wave, the warning lamp keeps lit to notify the other vehicle of the emergency area in an emergency.
By installing the device 8 in a plurality of vehicles, it becomes possible to communicate each other's emergencies with radio signals, and in the event of a failure or accident, a preliminary notification that is several steps earlier than visual inspection or sensors. Is possible. It is also ideal for lane restrictions due to construction, field verification, falling object handling, the end of traffic jams, and bad weather such as fog.
