Description

Vehicle driving information providing method and its device {driving infomation system}

According to the present invention, the traffic information of the preceding vehicle is informed to the trailing vehicle in a traffic driving situation such as a highway, and the trailing vehicle reduces accidents and prevents rapid braking to reduce fuel consumption and maintain smooth traffic flow. The present invention relates to a method for providing vehicle operation information and a device thereof. The conventional method for providing vehicle operation information includes a sensor or a camera that is sparsely installed on a road, and uses a sensor or a camera to track the driving state and driving speed of a preceding vehicle. Provided to the driver.

However, because the sensor or camera installed on the road and collecting the driving information of the vehicle or the road is expensive to install, it cannot be densely installed in many sections, so it provides the driver with traffic information on the preceding vehicle or the preceding section in real time. I can't.

In particular, in a congested state where the driving condition is irregular, rapid acceleration and braking are repeated so that the smooth flow of the vehicle cannot be maintained, causing congestion and causing fuel waste, driver fatigue and safety accidents. Providing real-time driving information for a short distance up to several hundred meters in real time can predict the driving speed of the section to be driven forward, thus preventing accidents, reducing unnecessary acceleration or unnecessary braking, and saving fuel and reducing driver fatigue. Can be.

Therefore, in order to provide driving information of a short-range preceding vehicle to the driver in real time, the driving information of the preceding vehicle is directly transmitted to the trailing vehicle at a short distance so that the driving situation of the preceding vehicle can be judged without a sensor or a camera installed on the road. To be present;

Alternatively, the traffic information communication method and apparatus for transmitting the driving information collected individually by the preceding vehicle to the virtual manager (server) and receiving the traffic information currently required from the virtual manager (server) to assist in driving. It is about.

Conventional road traffic information transmission device is measured by a sensor or a camera installed on the road and the measured information is displayed on the road facility to deliver the road traffic status information to the following driver.

However, sensors or cameras to measure the driving conditions of vehicles and on-road facilities that display these information have large installation costs and thus cannot be densely installed in many places, and thus do not provide sufficient information in real time to the following drivers.

In particular, the information on the short-distance traffic between 100 and 300 meters is an important cognitive distance in determining the acceleration or deceleration of the vehicle. If there is not enough traffic information at these cognitive distances, traffic flow is delayed due to unnecessary acceleration or unnecessary deceleration, or It may cause traffic accidents.

For example, instead of accelerating suddenly without knowing that the vehicle was stopped at 300 meters ahead and braking again, grasping traffic information ahead of 300 meters and slowly slowing down without sudden brakes can keep the traffic flowing smoothly. This reduces the energy consumption of the vehicle.

In other words, in the top-down traffic information delivery method that collects and provides information at a fixed place in the past, the idea of the information providing method is changed to collect traffic information at a fixed measuring point and traffic information at a fixed location. Instead of providing information, it collects the appropriate information selectively from the traffic information measured by a large number of individual vehicles in motion, that is, it is provided with traffic information transmitted from a preceding vehicle that runs ahead of a certain distance, such as a stiletto, so that it does not require facility investment. It is intended to solve the problem by a bottom-up traffic information delivery method that allows traffic information to be provided in real time.

In order to solve the above problems

1. A plurality of preceding vehicles traveling on the road transmits GPS coordinate information, driving speed, bearing information, etc., and the following vehicle receives these information and extracts only valid information from the received information to utilize the vehicle driving information;

2. Alternatively, in a plurality of preceding vehicles traveling on the road, GPS coordinate information, driving speed, and bearing information are transmitted to a virtual manager (server), and the virtual manager (server) collects the received information as valid information. In order to solve the problem, the trailing vehicle uses the information received from the virtual manager (server) as vehicle driving information by requesting the virtual manager (server) for the traffic information of the place corresponding to the expected route of its movement. do.

It is not necessary to install the driving information measuring device and display device of the vehicle installed on the conventional road, and the cost is reduced, and the preceding vehicle in a place where sufficient viewing distance such as sunset, bad weather, fog road, hill road, and curved road is not secured. It is possible to check the driving status of the road, and sufficient road traffic information provided in real time is not required for rapid acceleration or rapid braking, which can reduce traffic congestion and reduce energy consumption of the vehicle with a smooth traffic flow.

The present invention

1. The driving information transmitted from the plurality of preceding vehicles 101 so that driving information of the plurality of preceding vehicles 101 may be transmitted to the plurality of short distance trailing vehicles 102 in real time to help safe driving. A receiving unit 301 for receiving information; And a central processing unit 303 for extracting valid information from the information received by the receiving unit 301 and converting the information into usable data; And a display unit 304 for transmitting the available data generated by the central processing unit 303 to the driver; a sensor unit 302 for measuring driving information of the own vehicle; and driving information of the own vehicle to the trailing vehicle 102. 'Vehicle driving information providing method and apparatus thereof, characterized in that to obtain the driving information of the preceding vehicle 101 by the one-way communication between the vehicle and the device consisting of a transmitter 305 to enable

2. a sensor unit 402 for measuring its own driving information; The transmitter 405 transmits the data measured by the sensor unit 402 to the virtual manager (server 408) and the receiver 401 for receiving valid driving information requested by the virtual manager (server 408). ); The apparatus includes a display unit 404 for displaying driving information received by the receiving unit 401 and a central processing unit 403 for managing these information flow steps, and bidirectional communication between the vehicle and the virtual manager (server 408). The vehicle driving information providing method and apparatus thereof, which are obtained by using the driving information of the vehicle 101, will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an example of measuring and displaying conventional road driving information. The road information transmission of a conventional vehicle is performed by a road traffic of a preceding vehicle 101 through a speed meter 202 or a camera 201 which is sparsely installed on a road. The driving information is collected and the collected information is transferred to the trailing vehicle 102 to the trailing vehicle 102 by the information transmission device (light signboard 203) installed on the road.

However, the conventional road driving information transmission method is satisfied to provide the traffic information in the middle distance and long distance because it is measured and displayed using the facilities on the road, which are expensive to install and manage, and is effective in providing the traffic information in the short distance section. It was not.

In particular, when the driver's field of view is insufficient, such as at night or in bad weather, on hills, or on curved roads, short-distance traffic information of 100 to 500 meters is required, but facilities for measuring and displaying road driving information for cost reasons. Since 201, 202, and 203 could not be densely installed, there was a limit in providing traffic information.

In particular, when congestion begins immediately beyond the hill as shown in FIG. 2, if the trailing vehicle 102 does not provide enough road traffic conditions across the hill, the accelerated trailing vehicle 102 has to brake rapidly beyond the hill so There is a risk of a safety accident.

The reason why the road traffic information was not delivered to the following driver is because of the top-down information transmission method in which information is collected and transmitted at a fixed measuring point on the sparse road.

In order to solve this problem, if the concept of road driving information measurement and information transmission is changed, individual vehicles measure road driving information in real time and transmit the collected information to another vehicle or a virtual manager (server). Think of a bottom-up information delivery method for transmitting the information to another vehicle to receive and use the information.

That is, the bottom-up information transfer method is a principle that the sum of road driving information in small units produces the entire traffic information.

As such, when the driving information of the preceding vehicle is provided from the preceding vehicle 101 in real time, the trailing vehicle 102 may receive the driving information of the vehicle to be forwarded in a few seconds or minutes in real time, so unnecessary rapid acceleration or braking is unnecessary. It can maintain smooth driving speed, prevent accidents, and reduce automobile fuel.

More specifically, as shown in FIGS. 3, 4 and 6, the driving information collected from one's own vehicle is transmitted from a plurality of individual vehicles, and the driving information received from a plurality of other vehicles is received and the vehicle information is transmitted to one's own vehicle operation. Extract valid information and use it as driving information;

Alternatively, as shown in FIGS. 5 and 7, the driving information collected from the own vehicle is transmitted to the virtual manager (server), and the driving information necessary for the self is provided by a plurality of preceding vehicles 101 by the virtual manager (server 408). There is a method of providing vehicle driving information that receives the information collected from the driving information transmitted to the vehicle and utilizes the driving information of the trailing vehicle 102.

At this time, the communication between the vehicle and the virtual manager (server 408) utilizes a well-known two-way wired and wireless communication technology, and a repeater 407 for wireless communication between the vehicle and the virtual manager (server 408) is provided for smooth communication. Make it possible.

6 is a block diagram of an inter-vehicle communication terminal 300 for implementing a driving information transmission method using the vehicle and the one-way communication method between the vehicle and the receiver 301 for receiving driving information transmitted from other vehicles in the vicinity. The central processing unit 303 for determining whether the received information is suitable for the vehicle and converting the received information into data suitable for the vehicle, and the display unit 304 for displaying the processed information to the driver, and It is composed of a sensor unit 302 for measuring the driving information so as to provide the driving information to another vehicle and a transmitter 305 for transmitting the measured information.

The information transmitting method of the receiving unit 301 and the transmitting unit 305 receives and receives information using a well-known one-way wireless communication technology capable of short-range wireless communication of about 500 meters.

In addition, the contents of the received and sent information include the unique name of the device, the current GPS coordinates, the current direction of movement, and the current speed of the device. May contain information.

The current own direction of movement value may be transmitted to a sensor for measuring azimuth, it is possible to extract its own direction of movement by the change of the current GPS coordinate value and the previous GPS coordinate value, and their speed is also unit time Since the speed can be extracted by changing the GPS coordinate value, the incoming and outgoing information can be minimized to the previous GPS coordinate value and the current GPS coordinate value.

The azimuth value is a sensor for measuring a direction, and is a sensor for selecting a vehicle having a different traveling direction among a plurality of preceding vehicles 101.

In addition, the inclination value is for measuring the inclination of the driving lane and may use a gyro sensor for measuring the direction of gravity.

The emergency signal value is a signal value for informing an accident situation or a dangerous situation such as an emergency signal of a vehicle.

The sensor unit 302 is where a GPS sensor or the like for collecting the measured values is located.

The central processing unit 303 selects only signals of a vehicle having the same moving direction as its own vehicle from among a plurality of pieces of information received, and selects only vehicles within a predetermined distance in consideration of the traveling speed of its own vehicle, The traveling speed is analyzed to display the average speed of the corresponding point on the display unit 304 corresponding to the display device.

The analyzed information includes providing the most suitable traveling speed.
