Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle driving state information providing system,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a system and a method for providing vehicle driving condition information.

Due to the increasing number of cars and the increasingly complicated road conditions each year, the driver's driving conditions are getting worse every day. As a result, many drivers use a navigation system mounted on the vehicle.

Generally, a navigation device for a vehicle is equipped with a global position system (GPS) receiver, so that the current position of the vehicle can be accurately known. Therefore, when the user inputs a desired destination, the vehicle navigation apparatus notifies the driver of the shortest path from the current position to the destination through voice or image. Accordingly, the user can arrive at a desired destination accurately at a short time, and can safely reach a desired destination even if the destination location is not precisely known.

However, the driver can not precisely know the surrounding traffic situation only by using such a vehicle navigation device. That is, the driver can not know exactly how many vehicles are running around his or her own vehicle, and the driving information such as the traveling path, driving speed, or driving direction of the surrounding vehicle.

To this end, a technique has been conventionally provided in which a video captured in real time is provided to a user via the Internet to grasp local traffic conditions.

Accordingly, in the terminal built-in the GPS receiver, the current position of the terminal is grasped in the map of the terminal, and the direction of the traffic or the traffic situation of the surrounding road is the CCTV position displayed on the map, The moving image can be checked in real time.

However, such a conventional technique is based on an image photographed by a CCTV installed in the vicinity of a certain road, so that it can not grasp only a traffic situation in a specific area. In addition, since only the state of the vehicle marked on the CCTV can be confirmed, the traveling state and the traveling route of the specific vehicle can not be grasped.

First, with reference to FIG. 1, a description will be given of a vehicle running state information providing system according to an embodiment of the present invention.

FIG. 1 is a block diagram of a system for providing vehicle driving condition information according to an embodiment of the present invention.

1, the system for providing information on the running state of an automobile according to an embodiment of the present invention generates driving state information through a driving state information acquiring apparatus 100, a driving state information generating apparatus 200, and a communication network 80 And a user terminal 70 connected to the device 200

The driving state information obtaining apparatus 100 is installed in a vehicle, particularly a vehicle for collecting traffic information, and provides moving picture information, position information, and time information photographed by the vehicle to the driving state information generating apparatus 200. [

The traveling state information acquisition apparatus 100 includes a photographing section 10, a GPS receiving section 20, and a signal transmitting section 30. [

The photographing unit 10 is a camera or the like. The photographing unit 10 photographs a moving image while being supplied with electric power, and transmits moving image information about the photographed moving image to the signal transmitting unit 30. The photographing unit 10 may be a camera for photographing a moving image by being operated by a passenger on a traveling automobile.

The GPS receiver 20 recognizes the current position and the current time of the vehicle by using the signal received from the GPS, and outputs the position information and the time information to the signal transmitter 30.

The signal transmitting unit 30 is an interface for transmitting and receiving signals and is configured to combine moving picture information from the photographing unit 10 and position information and time information of the GPS receiving unit 20 and transmit them to the traveling state information generating apparatus 200 .

The driving state information generating apparatus 200 generates driving state display icon data including the driving information of the vehicle based on the moving picture information, the position information, and the time information from the driving state information obtaining apparatus 100, (80) to the user terminal (70).

The traveling state information generating apparatus 200 includes a map providing unit 40, a traveling state display control unit 50, and a storage unit 60.

The map data providing unit 40 is stored therein and provides a map of a specific area to the traveling state display control unit 50 via a communication network (not shown) such as the Internet based on the map information.

The traveling state display control unit 50 receives the moving picture information, the position information, and the time information transmitted from the traveling state information acquisition apparatus 100 to calculate the traveling speed of the vehicle, and displays the running speed of the vehicle on the map provided from the map providing unit 40 And transmits the data to the storage unit 60. The storage unit 60 stores the data for the driving status display icon. The data for each running status display icon includes vehicle position information, running speed information, time information, and a video signal.

The storage unit 60 stores data for the running status display icon transmitted from the running status display control unit 50. [ In this embodiment, the storage unit 60 may be a memory device such as a RAM (RAM). 1, the storage unit 60 is mounted as an element separate from the running status display control unit 50, but may be provided inside the running status display control unit 50. [

The user terminal 70 displays the traveling state of the vehicle on the basis of the traveling state indication icon data transmitted from the traveling state information generating apparatus 200 via the communication network 80 at the corresponding position with the traveling state indication icon. In the present embodiment, the user terminal 70 is used in a mobile terminal capable of being moved and carried and connected to the traveling state information generating apparatus 200 through the communication network 80 or in a fixed position, And may be a fixed terminal connectable to the state information generation apparatus 200. [ Examples of the mobile terminal may be a notebook computer, a mobile communication terminal such as a mobile phone, a mobile WiMAX (also referred to as a WiBro) communication system, a WiBro terminal, a PDA, and the like. The stationary terminal may also be a desktop computer or the like.

The communication network 80 may be a wired Internet or a wireless Internet.

The operation of the system for providing vehicle driving condition information according to an embodiment of the present invention having such a structure will be described with reference to FIGS. 2 and 3. FIG.

3 is a view illustrating an example of a driving status display icon according to an embodiment of the present invention. FIG. 4 is a flowchart illustrating an operation of the embodiment of the present invention FIG. 8 is a view showing an example of a display screen for displaying a driving state of a specific area by using a traveling state display icon according to FIG.

First, when power is supplied to a photographing unit 10 attached to a vehicle or operated by an occupant of a vehicle, the photographing unit 10 photographs a subject in a corresponding range and displays a raw image signal corresponding to the photographed image as a signal The GPS receiver 20 determines the position and current time of the vehicle equipped with the photographing unit 10 and transmits the position information and the time information of the vehicle to the transmitter 30 through the signal transmitter 30 wirelessly To the driving state information generating apparatus 200. [

Therefore, the running state display control unit 50 of the running state information generating apparatus 200 calculates the running speed of the automobile based on the position information of the automobile and the current time information. For example, the running state display control section 50 can calculate the traveling speed of the vehicle that is currently traveling on the basis of the difference between the times at which two points have passed.

In general, the moving state display control unit 50 may display the moving picture information, which is the moving picture information transmitted from the photographing unit 10, as MPEG or the like, And generates a video signal corresponding to an image displayed for a predetermined time at predetermined intervals. At this time, the driving state display control unit 50 can change the degree of compression of the original video signal according to the running speed of the car.

For example, if the car runs at an average speed of 120 km / h, it travels about 333 m in about 10 seconds, and travels about 166 m in about 10 seconds if the average speed is 60 km / h. Also, if the car runs at an average speed of 10km / h, it will travel about 27m in about 10 seconds.

If an image is taken at a rate of generating 30 frames per second, about 300 frames are generated for 10 seconds. In this case, when the average speed of the automobile on the expressway is about 120 km / h, the time required for moving about 10 km is about 300 seconds. Therefore, if the compression degree is 1/30 times, Lt; / RTI > seconds. Therefore, in order to make an image displayed for about 10 seconds at intervals of about 10 km, the degree of compression of the video signal is determined differently according to the traveling speed of the car. For example, when the traveling speed of the car is about 120 km / h, the photographed image is compressed to about 1/30 times, and when the traveling speed of the car is about 60 km / h, . In addition, when driving on a city road, images can be displayed for about 10 seconds at intervals of about 500 m. In this case, when the car travels at about 10 km / h for about 500 m, the captured image is compressed to about 1/18 times, and when the car travels about 500 m at about 5 km / h, 36 times.

When the vehicle travels on the expressway at an average speed (v) of 10 km, the traveling state display icon is displayed at an interval of 10 km. When the vehicle is traveling at an interval of 10 km, When the number of frames is 10 / a times, the photographed image is compressed into an image of 10 seconds long. Also, when the vehicle travels on a major road in the city and the average speed (v) is 500 m, the travel time icon is displayed at intervals of about 500 m. When an image is reduced by 10 / b times, a compressed image of about 10 seconds in length is obtained.

For this compression operation, the running status display control unit 50 displays video signals of some frames among the I frame (infra frame), P frame (previous frame) and B frame (bidirectional frame) Only the video signal of the P frame can be extracted and used.

When the video signal displayed for a predetermined period of time is extracted at each desired running interval, the running state display control unit 50 displays the extracted video signal, time information, running speed information, vehicle position information, And stores them as a bundle in the storage unit 60 as data for the running status display icons. At this time, the video signal for the running status display icon is a video signal for displaying the running status display icon displayed on the map. Accordingly, the storage unit 60 stores data for a plurality of running status display icons displayed in a time sequence at a predetermined distance, for example, at intervals of about 10 km, for example, for about 10 seconds.

Next, the operation of the traveling state display control section 50 for displaying the traveling state display icon at the corresponding position of the map provided from the map providing section 40 using the plurality of running state display icon data will be described.

The running status display control unit 50 has already stored vehicle information such as a vehicle on which the photographing unit 10 is mounted or a vehicle number on which the photographing unit 10 is mounted in a storage device (not shown) such as a memory .

First, when the operation of the running state display control unit 50 is started (S10), the running state display control unit 50 connects the user to the communication network 80 via the user terminal 70 and controls the running state display control unit 50 It is determined whether a service to be provided is selected (S11).

When the user does not want to use the service provided by the running status display control unit 50, the running status display control unit 50 does not provide a service for displaying the running information of the vehicle on the map as the running status display icon. Therefore, the traveling state display control unit 50 proceeds to the first step S11 to determine the selection state of the user.

However, if a display request of the driving status display icon is generated for the user to use the service provided by the driving status display control unit 50 through the user terminal 70 in step S11, the driving status display control unit 50 Transmits data related to the initial screen to the user terminal 70 through the communication network 80 so that an initial screen can be displayed on the display device of the user terminal 70 in step S12.

Then, the running state display control section 50 judges the display condition selected by the user (S13). That is, the user can select a desired display condition by using a function key, an instruction key, or the like displayed on the initial screen displayed on the display device of the user terminal 70.

Therefore, the running status display control unit 50 reads the data for the running status display icon corresponding to the condition selected by the user from the storage unit 60 ((S14) From the map providing unit 40 (S15).

Then, the traveling state display control section 50 transmits the read map information and the traveling status display icon data to the user terminal 70 (S16). Therefore, the display device of the user terminal 70 displays a map in which the driving status display icon is displayed at the position of the vehicle. At this time, the running status display control unit 50 can transmit the vehicle information such as the vehicle number to the user terminal 70, so that the vehicle information can be displayed on or near the running status display icon.

An example of a selection condition that can be selected by the user is as follows.

The user can specify the specific time and confirm the running information of the vehicle that has run for the specified time with the running status display icon. At this time, the user may select a specific area to display with time.

In this case, the traveling state display control unit 50 reads data for the traveling state display icon of the vehicle that has traveled for a specified time from the storage unit 60, and supplies the map information to the map data providing unit 40, And transmits the read data to the user terminal 70 via the communication network 80. Thus, the vehicle information that has traveled for the designated time is displayed on the map of the area with the running status display icon on the display device of the user terminal 70. [

Further, the user can select a specific vehicle and confirm the traveling route of the selected vehicle. In this case, the user can normally select the display period until desired period. Therefore, the running state display control unit 50 reads the image data for the running state display icon related to the vehicle designated by the user from the storage unit 60, and based on the position information of the vehicle included in the running state display icon image data Reads the map information of the area from the map providing unit 40 and transmits the map information to the user terminal 70 through the communication network 80. As a result, the display device of the user terminal 70 displays a running status display icon that moves along the traveling path of the designated vehicle. In this case, instead of moving the position of the traveling state display icon along the traveling path of the vehicle, the traveling path of the vehicle may be indicated by a line.

The user can also select a specific route. For example, when the user selects a route from the intersection of Gangnam Station to the Yeoksam Station intersection in Seoul, the running status display control unit 50 stores the image data for the running status display icon of the vehicle located in the selected route and the corresponding map information in the storage unit 60 and the map providing unit 40 and transmits them to the user terminal 70 through the communication network 80. At this time, the user can select a desired time zone. In this case, the running status display control unit 50 reads out only the video data from the storage unit 60 at the designated time out of the video data for the running status display icon of the vehicle located on the selected path, .

In addition, the user can select one of the traveling state display icons on the map displayed on the display device of the user terminal 70 using a mouse or the like. Then, at the time of selection, the images for the predetermined time are displayed sequentially on the basis of the image displayed on the desktop of the traveling status display icon. To this end, the running status display control unit 50 transmits the corresponding video signal to the user terminal 70 from the data for the running status display icon corresponding to the currently displayed running status display icon, or displays the currently displayed running status display The display unit 60 and the map providing unit 40 store the corresponding image signal and the map information among the data for the running status display icon and the corresponding map information that exist before and after the data for the running status display icon corresponding to the icon, And transmits them to the user terminal 70. At this time, the traveling state display control unit 50 transmits a video signal of a quantity that can be displayed for a predetermined time, for example, about 5 seconds, based on the time information of the selected traveling state display icon to the user terminal 70 Lt; / RTI >

The user terminal 70 activates a separate window to sequentially display an image corresponding to the video signal for the selected vehicle during the set time. For example, instead of the traveling state display icon for about 5 seconds before or after the user's selection time, the corresponding image can be displayed through a separate window. At this time, the information displayed through the running status display icon, that is, the vehicle running speed, the time information, the running direction, and the like, can be displayed as characters. As a result, the user can check the images taken by the vehicle, so that the user can grasp the surrounding environment and the surrounding situation. In an alternative embodiment, instead of sequentially displaying the images through a separate window, the images may be sequentially displayed on the desktop of the driving status display icon. In this case, only the video is displayed inside the traveling status display icon, so the traveling speed and current time of the car are not displayed.

In the present embodiment, the position at which the running status display icon is displayed is determined based on the position information of the vehicle.

As described above, since the data for one running status display icon is for displaying an image photographed while traveling for a predetermined mileage (for example, about 10 km) for a predetermined time (for example, about 10 seconds) The display icon must update the display information by calling data for a new running status display icon for each predetermined mileage.

Therefore, when the travel distance of the vehicle is moved by a predetermined travel distance, or when a predetermined time has elapsed, the travel state display controller 50 stores the data for the new travel state display icon and the corresponding map information in the storage unit 60 It is necessary to read from the map providing unit 40 and change the image of the desktop of the traveling state display icon and the traveling information.

Referring to FIG. 3, the running status display icon 300 displayed on the display device of the user terminal 70 will be described in more detail.

3, the running status display icon 300 has a circular orientation display section 301, a speed and time display scale 302, a time display section 303, a travel direction display section 304, a speed display section 305, And a desktop screen 306. FIG.

The azimuth display unit 301 indicates the azimuths of north, south, east, and west, and is denoted by alphabetic characters (E, W, S, N).

The speed and time display scale 302 is a scale displayed so that the traveling speed and time of the vehicle can be known. One scale interval in terms of running speed is about 20 km / h, and in a time scale, The interval (on the hour hand) or about 5 minutes (on the minute hand). Therefore, the speed range indicated by the speed and time display scale 302 in the running status display icon 300 shown in Fig. 3 is about 0 to 240 km / h, and is displayed by the speed and time display scale 302 The time range is about 1 to 12 hours.

The time display unit 303 is an arrow indicating the current time, and the position of the arrow is determined based on the time information of the data for the running status display icon. Among the two arrows, the short arrow indicates "hour" and the long arrow indicates "minute".

The traveling direction display section 304 is an arrow indicating the traveling direction of the vehicle, and the position of the arrow is determined based on the vehicle position information of the data for the traveling state display icon.

The speed display unit 305 is an arrow indicating the running speed of the vehicle, and the position of the arrow is determined based on the running speed information of the data for the running status display icon.

 The moving picture corresponding to the video signal of the data for each running status display icon is displayed on the desktop screen 306 for a predetermined time, for example, for about 10 seconds.

The color, length, and shape of the arrows 303, 304, and 305 may be differentiated from each other on the running status display icon 300. [

The traveling state display icon 300 shown in Fig. 3 indicates a state of traveling in the southeast direction at about 12:15 at about 100 km / h.

FIG. 4 shows an example of a map including a driving status display icon displayed on the display device of the user terminal 70. FIG.

In FIG. 4, a running status display icon corresponding to all five vehicles is displayed.

Thus, the running information of the automobile is converted into the running status display icon and displayed on the map, so that the running information of the vehicle can be easily and quickly grasped.

Also, the driving state of each vehicle and the degree of traffic congestion can be grasped by using the traveling state display icon displayed on the map. Therefore, the driver of the vehicle can drive the vehicle by finding the travel route which is less congested, so that the travel time to the destination can be shortened and the traffic volume can be dispersed.

Furthermore, it is possible to track the traveling route to a specific vehicle.

Next, a description will be given of a system for providing information on the running state of the vehicle according to another embodiment of the present invention with reference to FIG. The same reference numerals are assigned to the components that perform the same operations as those of FIG. 1, and a detailed description thereof will be omitted.

5 is a block diagram of a system for providing information on the running state of a vehicle according to another embodiment of the present invention.

As shown in FIG. 5, the vehicle running state information providing system according to the present embodiment is similar to that shown in FIG. 1, except that the running state information obtaining apparatus 101 further includes a signal processing unit 90 .

In this driving state information acquisition apparatus 101, the photographing section 10 outputs the moving picture information about the photographed moving picture to the signal processing section 90, and the GPS receiving section 20 uses the signal received from the GPS, And outputs the position information and the time information to the signal processing unit 90.

The signal processing unit 90 calculates the traveling speed of the vehicle based on the position information of the vehicle and the current time information output from the GPS receiving unit 20 and displays the moving image information output from the photographing unit 10 based on the traveling speed of the vehicle And extracts a moving picture to be displayed for a predetermined time at predetermined intervals. Then, the signal processing unit 90 transmits the calculated traveling speed, time information, vehicle location information, and moving picture information about the extracted moving picture to the traveling state information generating apparatus 201 through the wireless communication network through the signal transmitting unit 30 Output. At this time, the traveling speed calculating operation and the moving picture compressing operation can be performed in the same manner as described above with reference to FIG.

Therefore, the running state display control unit 51 of the running state information generating apparatus 201 generates a running state display icon image signal (hereinafter referred to as " running state information ") for the video signal, time information, running speed information, and vehicle position information transmitted from the running state information obtaining apparatus 101 And stores them as a bundle in the storage unit 60 as data for the running status display icons. As described above, the video signal for the running status display icon is a video signal for displaying the running status display icon displayed on the map.

The operation of the traveling state display control section 51 for displaying the traveling state display icon at the corresponding position of the map provided from the map providing section 40 using the data for the plurality of traveling state display icons is shown in Figs. The description of the operation will be omitted.

As described above with reference to Figs. 1 to 4, in this embodiment, since the travel information of the vehicle is converted into the travel state display icon and displayed on the map, the travel information of the vehicle and the degree of traffic congestion can be easily It can be grasped quickly.
