Abstract

PURPOSE: A communication system between vehicles is provided to exchange information between vehicles easily and exactly by using A/V device without the large scale investment or an equipment period, thereby reducing the danger of accident. CONSTITUTION: A distance sensor(1) measures the distance to an another vehicle. An infrared data transmitter(2) transmits and receives between vehicles. Information display units(3-6) displays the transmitted information. A control unit(7) controls the elements wholly. The elements mounted to each car are the same. The distance sensor(1) can measures the distance to the car next ahead and operates the communication system between cars when the distance between cars becomes a constant distance. A passenger can use every A/V devices such as a keyboard(6), a microphone(5), an information providing screen(4) and a speaker(3) etc. if possible.

Description

Inter-vehicle communication system {COMMUNICATION SYSTEM FOR VEHICLES}

The present invention relates to an inter-vehicle communication system, and more particularly, an inter-vehicle communication system in which a user communicates with another vehicle through a key operation or a microphone and receives information of another vehicle through an information providing screen or a speaker. It is about.

As a general method of communication between vehicles, a basic method using a hand signal or an indicator is mainly used, and in recent years, researches for obtaining the position and driving information of another vehicle with the help of navigation devices, etc. have been conducted.

However, the use of hand signals or indicator lights only depends on the sensational judgment by the driver's confirmation, so sufficient communication is insufficient, and especially when the driver's vision is unclear due to rain or fog, it may cause misjudgment. There is a problem that can cause traffic accidents.

In addition, in the case of using the navigation system, a large amount of equipment and time are invested in the system construction because of managing the global area, and there is a problem that it is difficult to obtain detailed information in real time.

Accordingly, the present invention is to solve the above problems, by enabling easy and accurate information exchange between vehicles using A / V equipment without a large investment or facility period, such as automatic navigation system, communication between vehicles more The purpose is to provide an inter-vehicle communication system that can clarify and eliminate the risk of accidents.

In order to achieve the above object, the present invention comprises a distance sensor for measuring the degree of distance with other vehicles, an infrared data transmitter for transmitting and receiving information between vehicles, information display means for displaying the transmitted information, and a control unit for controlling them integrally An inter-vehicle communication system is provided.

In addition, the communication system starts to operate when the distance from the other vehicle measured by the distance sensor falls within a predetermined range.

The infrared data transmitter is also mounted at the front of the vehicle.

In addition, the information display means includes a keyboard, a microphone, an information providing screen, a speaker, and the like.

1 is an overall schematic diagram of an inter-vehicle communication system according to an embodiment of the present invention.

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

1 is an overall schematic diagram of an inter-vehicle communication system according to the present invention, which includes a distance sensor 1 for measuring a degree of distance from another vehicle, an infrared data transmitter 2 for transmitting and receiving information between vehicles, and displaying the transmitted information. It consists of the information display means 3-6, and the control part 7 which integrally controls these.

In Fig. 1, the A-CAR and the B-CAR have the same structure (basically, all related vehicle systems are identically modularized and mounted).

If the A-CAR is stationary, the rear B-CAR can pass information to the A-CAR and obtain it.

The distance sensor 1 can measure the distance between the vehicle in front of the vehicle, and when this information determines that the vehicle distance is within a certain distance, the communication system between A-CAR and B-CAR, which has been waiting, starts to operate. .

The interface between the passenger and the system may use all possible A / V devices, such as a keyboard 6, a microphone 5, an information display screen 4, a speaker 3, and the like. The information input by the passenger through the keyboard 6 or the microphone 5 is transmitted to another vehicle through the infrared data transmitter 2 mounted at the front of the vehicle, and the transmitted information is inputted to the control unit 7. After the information processing process, the control unit 7 generates a display signal. This display signal is transmitted to the passenger via the information providing screen 4 or the speaker 3.

The mutual interface may be blocked according to the needs of the passengers, i.e., when information exchange is not desired or when information exchange is completed, or when the vehicle is driven, i.e., high-speed driving or starting of an A-CAR.

Information that can be exchanged through these systems may indicate a dangerous situation for the A-CAR, such as a door open, a tail light on, a tire condition or a drowsiness warning of the driver. Inform A-CAR about A-CAR's intentions, such as requesting information, and about A-CAR, such as the shortest route to the destination or how to get there, and information on destinations (size, entry method, precautions, etc.) This may be the case.

As described above, through the communication with other vehicles using the communication system according to the present invention, it is possible to obtain the same effect as that obtained in an automatic navigation system without a large investment or facility period.

In addition, it is effective in safe driving by the necessary information through communication with other vehicles and additional information from the outside.

In addition, by using the A / V device, the passenger can easily benefit from the automated system, and can increase the satisfaction of the passenger by having a rapport with a real person rather than a connection with a machine.
