Hereinafter, the working principle and embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a control block diagram of a vehicle communicating externally in accordance with one embodiment.

1, a communication system 1 according to an embodiment may include a vehicle 100, a peripheral vehicle 50, a communication network 70, a mobile terminal 30, and a server 20. [

In a typical communication system, data of a vehicle can be stored in a server through communication with the vehicle and the server. In addition, the data stored in the server can be transmitted to the vehicle through communication with the vehicle and the server. The vehicle uses the communication system to process the received data into driving information and operation logs to provide various services to the user can do.

However, in a situation where the vehicle can not directly communicate with the server 20, that is, when the vehicle 100 is located in a shaded area where wireless network connection is impossible, communication with the server 20 is impossible and data can not be transmitted or received.

Therefore, when the vehicle is located in such a communication shadow area, a method of temporarily storing data in a storage space in the vehicle and then transmitting the data may be utilized.

However, the storage space in the vehicle has a limitation in storing data continuously, and in a region where the wireless network environment is poor, the vehicle is continuously located in the shaded area, so data loss will occur if the storage capacity is exceeded.

If the internal storage capacity is exceeded, the vehicle may not be able to erase the oldest data or store new data, and even if the vehicle is out of the communication shadow area, if the data transmission speed is slow, have.

In order to prevent such data loss, there is a method of utilizing a short-range wireless communication network such as V2X in addition to a long-distance wireless communication network such as LTE in a vehicle. Here, V2X communication refers to a system in which a vehicle itself becomes a subject and shares information with other portable terminals, a communication network, or vehicles, and refers to a communication technology between a vehicle and all interfaces.

Specifically, the V2X can be classified into Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I) and Vehicle-to-Pedestrain (V2P) And the vehicle 100 can transmit and receive data of the vehicle 100 through communication with the surrounding vehicle 50. [

As such, V2X communication is basically based on the communication system between the surrounding infrastructure and the vehicle, rather than utilizing the base station. Therefore, if there is an infrastructure for V2I or a vehicle with V2V installed nearby, none.

Therefore, when the vehicle 100 is located in a shaded area where wireless communication with the server 20 is impossible, a storage space other than the vehicle 100 can be ensured by transmitting data to nearby vehicles by using this V2X communication, The data can be transmitted to the server using the wireless network transmission of each vehicle, thereby preventing data loss.

Hereinafter, a vehicle 100 according to an embodiment for preventing such data loss will be described.

The vehicle 100 includes a communication unit 110, a storage unit 120, and a control unit 130.

First, the communication unit 110 can transmit and receive various data related to the vehicle 100 from the outside of the vehicle 100, for example, the surrounding vehicle 50, the communication network 70 and the mobile terminal 30. [

The communication unit 110 may store the received data in the storage unit 120 through the control unit 130 or may store the data to be transmitted to the outside in the storage unit 120. [ The communication unit 110 may use the V2X communication described above to transmit various information related to the vehicle 100. [

The V2X communication used by the communication unit 110 according to an embodiment uses a DSRC (Dedicated Short Range Communication) or a WAVE (Wireless Access in Vehicular Environment) as a standard and communicates with the nearby vehicle 50 through a frequency of 5.9 GHz band .

Also, the communication unit 110 can perform communication with the surrounding vehicle 50 included in the preset range, and in this case, the predetermined range may mean the V2V transmission range. For example, the communication unit 110 may transmit data of the vehicle 100 to the nearby vehicle 50 located within the range of 300 m to 500 m.

On the other hand, the above-described range or protocol is only an example of how the disclosed communication unit 110 communicates with the surrounding vehicle 50 and can be variously changed.

The communication unit 110 may include at least one of a short-range communication module, a wired communication module, and a wireless communication module, for example, one or more components that enable communication with an external device.

The short-range communication module uses a wireless communication network, such as a Bluetooth module, an infrared communication module, an RFID (Radio Frequency Identification) communication module, a WLAN (Wireless Local Access Network) communication module, an NFC communication module, and a Zigbee communication module, And may include various short range communication modules for transmitting and receiving.

In addition to the Wifi module and the wireless broadband module, the wireless communication module may be a GSM (Global System for Mobile Communication), a CDMA (Code Division Multiple Access), a WCDMA (Wideband Code Division Multiple Access) ), Time Division Multiple Access (TDMA), Long Term Evolution (LTE), and the like.

The wireless communication module may include a wireless communication interface including an antenna and a transmitter for transmitting signals to the peripheral vehicle 50. [ The wireless communication module may further include a signal conversion module for modulating the digital control signal output from the control unit 130 into an analog type wireless signal through a wireless communication interface under the control of the control unit 130 to be described later.

In addition, the wireless communication module may include a wireless communication interface including an antenna and a receiver for receiving the signal transmitted by the peripheral vehicle 50. In this case, the wireless communication module may further include a signal conversion module for demodulating the analog type wireless signal received through the wireless communication interface into a digital control signal.

The communication unit 110 may further include a wired communication module for transmitting the configuration and data in the vehicle 100. The communication unit 110 may be a CAN (Controller Area Network), a LIN (Local Interconnect Network), a MOST (Media Oriented System Transport Modules, and the like.

The storage unit 120 may store various data such as data of the vehicle 100 and data received from the peripheral vehicle 50 by the communication unit 110.

Particularly, when the communication unit 110 of the vehicle 100 can not connect to the server 20, for example, when the vehicle 100 is in a communication incommunicable environment such as a communication shade area, And may be a buffer for storing data.

A buffer (buffer) is a memory area that temporarily stores data while transferring data from one place to another.

The storage unit 120 may temporarily store data when the vehicle 100 is in a shaded area where wireless network connection is impossible. The data temporarily stored in the storage unit 120 may be transmitted again by the communication unit 110 when the vehicle 100 enters an environment in which the vehicle 100 can access the wireless network.

For this purpose, the storage unit 120 may be implemented as a cache, a ROM (Read Only Memory), a PROM (Programmable ROM), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM) Volatile memory device such as a nonvolatile memory device or a random access memory (RAM), or a storage medium such as a hard disk drive (HDD) and a CD-ROM. However, the present invention is not limited thereto.

The control unit 130 can select the peripheral vehicle 50 to transmit the cooperation request when the remaining storage space of the storage unit 120 is smaller than the predetermined storage space. At this time, the cooperative request may refer to a signal requesting coordination for allocation of storage space for storing the data of the vehicle 100.

The control unit 130 determines whether the remaining storage space of the storage unit 120 is smaller than the predetermined storage space when the vehicle 100 is operated for a long time in the communication shadow area, It can be judged that it is not enough to store.

If the remaining storage space of the storage unit 120 is smaller than the predetermined storage space, the controller 130 may select the neighboring vehicle 50 to transmit the cooperation request (A).

Specifically, the control unit 130 can select a peripheral vehicle 50 having a similar route to the vehicle 100, among the peripheral vehicles located within a range in which V2V communication is possible. In this case, the number of the selected peripheral vehicles 50 may have a predetermined value and may be plural.

For this, the control unit 130 may utilize the map information of the navigation, and may utilize the location information of the nearby vehicle and the route search information of the nearby vehicle. The location information of the surrounding vehicles and the route search information of the surrounding vehicles can be received by the communication unit 110. [

The control unit 130 transmits data of the vehicle 100 to the selected nearby vehicle 50 and transmits a control command to the surrounding vehicle 150 to store the data of the vehicle 100 can do.

Meanwhile, the control unit 130 may be integrated with a storage medium capable of storing data, and may be integrated into a system on chip (SOC) built in the vehicle 100. However, there is not only one system-on-chip included in the vehicle 100, but there may be a plurality of system-on-chips, so that the system-on-chip is not limited to being integrated into only one system-on-chip.

Hereinafter, a specific operation of the control unit 130 will be described with reference to FIGS. 2 and 3. FIG.

FIG. 2 is a diagram for explaining a method of transmitting a cooperation request to a neighboring vehicle according to an embodiment, FIG. 3 is a flowchart illustrating a method of transmitting a cooperation request to a neighboring vehicle according to an embodiment, FIG. 8 is a diagram for explaining a method of transmitting a cooperation request. FIG.

Referring to FIG. 2, when the vehicle 100 is in a communication incapable state, such as when the vehicle 100 is located in a communication shade area, the vehicle 100 according to the embodiment selects the nearby vehicle 50 to transmit the cooperation request signal (A). In this regard, a detailed selection method will be described later.

Specifically, the control unit 130 may select the nearby vehicle 50 to request the data storage cooperation according to at least one of the traveling path of the vehicle 100, the storage space of the surrounding vehicles, and the time at which the surrounding vehicle leaves the shaded area (A).

The vehicle 100 can transmit the cooperation request signals 201, 202 and 203 to the selected nearby vehicles VT, VT 'and VT' ', and utilize the V2V communication at this time.

The neighboring vehicles VT, VT 'and VT' 'receiving the cooperation request signals 201, 202 and 203 from the vehicle 100 transmit the coordinatable signals 204 and 206 or the cooperativeness signal 205 to the vehicle 100, As shown in FIG.

After considering the internal storage space allocatable amount Sa of the vehicle, the neighboring vehicles VT, VT 'and VT' 'transmit coordinatable signals to the vehicle 100 when there is space in the storage space allocatable amount Sa . Further, when it is determined that the neighboring vehicles VT, VT ', VT " can not cooperate, a cooperating signal can be transmitted to the vehicle 100. [

Specifically, the vehicle 100 can transmit a cooperative request signal including a necessary amount of data, and the nearby vehicles VT, VT ', and VT' 'receiving the cooperative request signals can receive data acquisition amounts per second (Dsec, [MB / s]), the total storage capacity of the car, the current storage capacity, and the like.

The neighboring vehicles VT, VT 'and VT' 'can determine the storage space allocatable time Tsec by Equation 1, and Equation 1 is as follows.

[Formula 1]

In this case, Tsec is the storage space allocable time, Stotal is the total storage capacity, and Sstored is the current storage amount. Dsec means data collection per second.

Once the storage space allocatable time is determined, the neighboring vehicles VT, VT ', VT' 'can determine the time to leave the shadow area from the communicable area entry point (Texit). In this case, the entry point for the communication area means a point outside the communication shadow area, and the time for leaving the shadow area (Texit) means a time for entry into the communication area.

The nearby vehicles VT, VT ', VT' 'receiving the cooperation request signal from the vehicle 100 can confirm the time (Texit) to leave the shadow area based on the navigation information such as the travel route, It is possible to determine whether or not to transmit an uncoordinate signal or a co-operable signal by comparing the time (Texit) with the above-mentioned storage space allocatable time (Tsec).

Specifically, when the time to leave the shadow area (Texit) is longer than the storage space allocatable time (Tsec), it means that there is no storage space to be allocated before leaving the shadow area. In this case, VT ") can transmit an uncorrectable signal that the vehicle 100 can not store data.

On the other hand, the neighboring vehicles VT, VT 'and VT' 'are able to leave the shadow area before all of the storage space is allocated if the time Texit to leave the shadow area is shorter than the storage space allotable time Tsec Meaning that the vehicle 100 can be transmitted with a cooperative signal.

At this time, the storage space allocatable amount Sa can be determined according to the time (Texit) for leaving the shadow area and the storage space allocatable time (Tsec) of the nearby vehicles VT, VT ', VT' 2.

[Formula 2]

In this case, Sa means the storage space allocatable amount, Tsec means the storage space allocatable time, Texit means the time to leave the shadow area, and Dsec means the data collection amount per second.

The storage space allotable time Tsec determined by Equation 2 can be transmitted to the vehicle 100 together with the cooperable signal.

Thereafter, the vehicle 100 transmits data packets 207, 207 'to the neighboring vehicles VT, VT' 'that have transmitted the cooperable signals 204, 206 excluding the neighboring vehicle VT' 208).

The neighboring vehicles VT and VT '' that have transmitted the data packets 207 and 208 from the vehicle 100 can transmit the data of the vehicle 100 to the server 20 when they are ready to communicate later.

In another embodiment, the vehicle 100 can utilize V2V communication to broadcast a cooperative request signal when the vehicle 100 is in a communication incommunicable state, such as when the vehicle 100 is located in a communication shadow area.

In this case, the vehicle 100 can transmit a cooperation request signal to all of the vehicles V1, V2, and V3 within the V2V communication range to which the vehicle belongs. The vehicles V1, V2, and V3 receiving the cooperative request signal from the vehicle 100 can transmit the cooperative or non-cooperative signals to the vehicle 100. [

The determination of the transmission of the cooperative or non-cooperative signal is the same as that of the embodiment described above. The vehicle 100 responds to the cooperative request signal of the vehicle 100, The neighboring vehicle 50 to request the cooperation of the data allocation can be selected (A).

The vehicle 100 selects a peripheral vehicle and then transmits a data packet of the vehicle 100 to the selected peripheral vehicle 50. When the selected peripheral vehicle 50 becomes ready to communicate later, And transmit the control command to the server 20 to transmit the data.

Referring to FIG. 3, when the vehicle 100 according to an exemplary embodiment is located in the communication shadow area 230, the vehicle 100 according to an exemplary embodiment of the present invention is set in a predetermined range, i.e., in the first range 200 in which direct V2V communication is possible, 50b, and 50c can be selected.

For example, assuming that the traveling path of the vehicle 100 is the traveling path that is the destination 300 and the traveling path of the surrounding vehicle 50a is the traveling path that is the destination 310 and the traveling path of the surrounding vehicle 50b is the destination And the vehicle 100 is a peripheral vehicle having a travel route most similar to the travel route of the vehicle 100 when the travel route of the peripheral vehicle 50c is the travel route of the destination 330 The peripheral vehicle 50a having the traveling route can be selected as the first peripheral vehicle.

At this time, navigation information including destination information and traveling route information of the vehicle 100 and the surrounding vehicle 50 can be transmitted and received and utilized.

The control unit 130 of the vehicle 100 can receive the storage space information of the first surrounding vehicle 50a from the first surrounding vehicle 50a and the storage space of the first surrounding vehicle 50a, It is possible to determine whether or not to allocate the data of the vehicle 100 to the first peripheral vehicle 50a based on at least one of the time at which the vehicle 50a leaves the shadow area.

Specifically, when the free storage space of the first peripheral vehicle 50a is larger than the predetermined storage space X1, the control unit 130 determines to allocate the data of the vehicle 100 to the first peripheral vehicle 50a .

For example, when the predetermined space is 100 Mbytes, the control unit 130 allocates the data of the vehicle 100 to the first peripheral vehicle 50a when the free storage space of the first peripheral vehicle 50a is larger than 100 Mbytes .

The control unit 130 also determines to allocate the data of the vehicle 100 to the first peripheral vehicle 50a when the time to leave the shadow area of the first peripheral vehicle 50a is shorter than the predetermined time T1 .

For example, if the predetermined time is 10 minutes, the control unit 130 determines whether the time of leaving the shaded area of the first surrounding vehicle 50a is less than 10 minutes, It can be determined to allocate data.

In this case, the time to leave the shaded area means the time required to travel to a point other than the shaded area, and points other than the shaded area can be identified using the map data.

The control unit 130 can transmit the data of the vehicle 100 to the first peripheral vehicle 50a when it is determined to allocate the data of the vehicle 100 to the first peripheral vehicle 50a. The control unit 130 may transmit a control command to the first peripheral vehicle 50a so that the data of the vehicle 100 is stored in the storage space of the first peripheral vehicle 50a.

The first peripheral vehicle 50a which has received the data allocation command of the vehicle 100 from the vehicle 100 can then store the data of the vehicle 100 in the storage space and, To the server 20 via the network.

As another example, when the storage space of the first peripheral vehicle 50a is smaller than the predetermined space X1 or the first peripheral vehicle 50a can not leave the shadow area within the predetermined time T1, The first peripheral vehicle 50a may issue a control command to select the second peripheral vehicle to transmit the cooperation request in the second range 210. [

In this case, the second periphery 210 may mean a range in which the first peripheral vehicle 50a can perform direct V2V communication.

The first peripheral vehicle 50a selects a peripheral vehicle similar to the vehicle 100 in the second range 210 as the second peripheral vehicle 52 by the control command of the controller 130 .

The control unit 130 determines whether or not the spare storage space of the second peripheral vehicle 52 selected by the first surrounding vehicle 50a is larger than the predetermined storage space X2 and the time at which the second surrounding vehicle 52 leaves the shadow area of the second surrounding vehicle 52 (50a) to determine whether or not to allocate the data of the vehicle (100) to the second peripheral vehicle (52) according to at least one of whether or not the vehicle is shorter than the predetermined time can do.

At this time, the predetermined storage space X2, which is a reference for comparison of the spare storage space of the second peripheral vehicle 52, is a predetermined storage space serving as a comparison reference of the spare storage space of the first peripheral vehicle 50a X1), and may have different values.

Similarly, the predetermined time T2, which is a criterion for comparison of the time for leaving the shaded area of the second peripheral vehicle 52, is a predetermined time that is a comparison reference of the time to leave the shaded area of the first peripheral vehicle 50a (T1), and may have different values.

The control unit 130 controls the second peripheral vehicle 52 to move the vehicle 100 in a state where the spare storage space of the second peripheral vehicle 52 is larger than the predetermined storage space X2, Quot; data "

The control unit 130 also determines to allocate the data of the vehicle 100 to the second peripheral vehicle 52 when the time to leave the shadow area of the second peripheral vehicle 52 is shorter than the predetermined time T2 .

The control unit 130 transmits the data of the vehicle 100 to the server 20 when the second peripheral vehicle 52 is in a communicable state if it is determined to allocate the data of the vehicle 100 to the second peripheral vehicle 52. [ To the second peripheral vehicle (52).

As another example, if the storage space of the second peripheral vehicle 52 is smaller than the predetermined storage space X2 or the time for leaving the shadow area of the second peripheral vehicle 52 is longer than the predetermined time T2, The control unit 130 may issue a control command to the second peripheral vehicle 52 to select a third peripheral vehicle whose traveling path is similar to the vehicle 100 within the third range 220. [ In the following process, the above-described process is repeated, so a description thereof will be omitted.

As such, as the vehicle to which the cooperative request is transmitted changes, faster and more efficient communication can be achieved.

4 is a flowchart of a vehicle control method according to an embodiment.

Referring to FIG. 4, the vehicle 100 according to an embodiment may select a first peripheral vehicle whose traveling path is similar to the vehicle 100 within a first range (401). At this time, the first range may mean an area range in which the vehicle 100 can perform direct V2V communication.

Thereafter, the vehicle 100 may determine whether the remaining storage space of the first peripheral vehicle exceeds a predetermined storage space X1 (402), and determine whether the remaining storage space of the first peripheral vehicle is larger than a predetermined storage space X1), it can be determined whether the time to leave the shaded area of the first surrounding vehicle is smaller than a predetermined time T1 (403). At this time, the time to leave the shaded area of the first surrounding vehicle may mean the time taken for the first surrounding vehicle to deviate from the shaded area.

The vehicle 100 may store the data of the vehicle 100 in the first neighboring vehicle if the time to leave the shadow area of the first nearby vehicle is less than the predetermined time T1. Specifically, the vehicle 100 may request allocation of a storage space for storage of data of the vehicle 100 to the first peripheral vehicle.

Thereafter, the vehicle 100 can transmit a control command to transmit the data of the stored vehicle 100 to the server 20 when the first surrounding vehicle is in a communicable state, The data of the vehicle 100 may be transmitted to the server 20 (405).

On the other hand, if the remaining storage space of the first peripheral vehicle and the time to leave the shadow area do not satisfy the predetermined condition described above (NO in steps 402 and 403), the vehicle 100 determines that the first peripheral vehicle is within the second range A control command may be issued to the first peripheral vehicle so as to select a second peripheral vehicle whose traveling path is similar to that of the vehicle 100 (411).

Thereafter, the vehicle 100 can determine whether the remaining storage space of the second peripheral vehicle exceeds a predetermined storage space X2 (412), and when the predetermined storage space X2 is exceeded, It may be determined whether the time for leaving the shadow area of the nearby vehicle is shorter than the predetermined time T2.

If the time to leave the shaded area of the second surrounding vehicle is shorter than the predetermined time T2, the vehicle 100 may store the data of the vehicle 100 in the second surrounding vehicle (414). Thereafter, the data of the vehicle 100 may be transmitted to the server 20 (415) when the second peripheral vehicle is in a communicable state in accordance with the control command of the vehicle 100. [

On the other hand, if the remaining storage space of the second surrounding vehicle and the time to leave the shadow area do not satisfy the predetermined condition described above (NO in steps 411 and 412), the vehicle 100 determines that the second surrounding vehicle is within the third range A control command may be issued to the second peripheral vehicle to select a third peripheral vehicle whose traveling path is similar to that of the vehicle 100 (421). Hereinafter, the above-described process is repeated.

5 is a flowchart of a vehicle control method according to an embodiment.

First, when the vehicle 100 according to the embodiment receives the cooperative request signal (510), the data collection amount per second (Dsec) in the vehicle can be confirmed (520).

When the data collection amount per second (Dsec) is confirmed, the storage space allocable time Tsec can be confirmed (530). Specifically, Equation 1 using the total capacity of the storage space in the vehicle, the present storage amount, and the like can be used.

Vehicle 100 may then ascertain 540 the time to leave the shaded area (Texit). At this time, the time to leave the shaded area (Texit) may mean the time taken to enter the communicable area.

When the data acquisition amount per second (Dsec) and the time to leave the shadow area (Texit) are confirmed, the vehicle 100 can determine whether the time (Texit) to leave the shadow area is less than the storage space allotable time (Tsec) 550).

If the time to leave the shadow area Texit is less than the storage space allotable time Tsec, the vehicle 100 can estimate the storage space allocatable amount Sa 560 and use Equation 2, have.

Thereafter, the vehicle 100 can transmit a cooperative signal including the estimated storage space allocatable amount (Sa) information to another vehicle (570).

As another example, when the time (Texit) to leave the shadow area is not less than the storage space allotable time (Tsec), that is, when the time (Texit) to leave the shadow area is greater than or equal to the storage space allotable time 100) may transmit an uncooperatable signal to the other vehicle (580).
