Hereinafter, a control method of the vehicle 100 and the vehicle 100 according to one embodiment will be described.

6 is a block diagram illustrating some components of the vehicle 100 according to one embodiment.

Referring to FIG. 6, in an embodiment, the vehicle 100 includes a sensing unit 110 for sensing the current state of the vehicle 100 and the antennas 120 and 130, a first antenna A storage unit 140 storing various information related to the vehicle 100, a navigation terminal 150 providing current driving information of the vehicle 100, and a first antenna 130. The first antenna 120, the second antenna 130, And a control unit 160 for changing an operation mode of the second antenna 120 and the second antenna 130. [

Specifically, the sensing unit 110 can sense whether the first antenna 120 and the second antenna 130 are operating in a single mode or in a diversity mode, and can detect whether the first antenna 120 and the second antenna 130 are operating in a diversity mode, It is also possible to detect whether an electronic device that interferes with transmission and reception is operating. It is also possible to detect whether or not the electronic device that interferes with the transmission and reception of radio waves of the second antenna 130 is operating. The sensing unit 100 may transmit the sensed result to the control unit 160.

And can transmit and receive signals to and from external servers of the antennas 120 and 130. Specifically, the antennas 120 and 130 transmit a signal to the outside in such a manner that an AC voltage modulated by a transmitter is radiated as electromagnetic waves to the outside, and when receiving the electromagnetic waves, an AC voltage evaluated by a receiver And can receive the signal.

Accordingly, the antennas 120 and 130 can be installed at various positions of the vehicle 100 in accordance with the use thereof. It is generally installed on the rear glass 18 of the vehicle 100 or on the top of the vehicle 100. However, the present invention is not limited thereto and may be installed in various positions of the vehicle.

In FIG. 6, the antenna is limited to the first antenna 120 and the second antenna 130, but the number of antennas installed in the vehicle 100 is not limited to this, and more antennas may be installed.

Hereinafter, the first antenna 120 will be described as a loop antenna 40 and the second antenna will be described with reference to a rear glass antenna 50 for convenience of description. However, the first antenna 120 and the second antenna 120 130 are not limited to the loop antenna 40 and the rear glass antenna 50, but may be applied to other antennas provided on the antenna surface vehicle 100 to which the application principle of the present invention can be applied.

The storage unit 140 may store various information related to the vehicle 100 and the antennas 120 and 130.

Accordingly, the storage unit 140 may include a nonvolatile memory device such as a cache, a read only memory (ROM), a programmable ROM (PROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), and a flash memory Or a storage medium such as a CD-ROM, a hard disk drive (HDD), or a volatile memory device such as a random access memory (RAM). The storage unit 140 may be a memory implemented in a separate chip from the processor described below in connection with the controller 120, and may be implemented as a single chip with the processor.

The navigation terminal 150 may transmit driving information about the current vehicle 100 to the controller 160 in real time.

As a remedy, the navigation terminal 150 receives a signal from a plurality of Global Positioning System (GPS) satellites located above the earth, identifies the current location of the current user, informs the user of the current location of the vehicle It can give the user the fastest route to the destination by grasping the current traffic situation.

 Accordingly, the navigation terminal 150 can transmit to the control unit 160 information about the current position of the vehicle, for example, whether it is passing through a tunnel, a bridge, or the like.

The control unit 160 may control the antennas 120 and 130 and the components included in the vehicle 100. The control unit 120 controls the operation mode of the first antenna 120 and the second antenna 130 based on the operation of the electronic device that hinders the reception of the radio waves from the first antenna 120 and the second antenna 130. [ Can be changed.

If the first antenna 120 is the loop antenna 40 and the second antenna 130 is the rear glass antenna 50, the control unit 160 determines whether the electronic device inhibiting the reception of the radio wave is operated The operation mode of the first antenna 120 and the second antenna 130 can be changed to the single mode or the diversity mode.

Specifically, when the camera 46 provided in the loop antenna 40 is operating, the radio wave receiving capability of the loop antenna 40 may be degraded due to noise generated in the camera 46. [ Therefore, in this case, the control unit 160 can stop the operation of the loop antenna 40 and operate the rear glass antenna 50 in the single mode.

On the other hand, when the camera 46 provided in the loop antenna 40 is not operating, noise is not generated in the camera 46, so that reception of the radio wave from the loop antenna 40 is not affected. Accordingly, in this case, the controller 160 operates the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

The control unit 120 can change the operation modes of the loop antenna 40 and the rear glass antenna 50 by differentiating the reception intensity of the radio waves from the loop antenna 40 and the rear glass antenna 50. [

Specifically, when the difference between the reception intensity of the loop antenna 40 and the reception intensity of the rear glass antenna 50 exceeds a predetermined range, the operation of the loop antenna 40 is stopped to efficiently operate the antenna And the rear glass antenna 50 can be operated in the single mode.

On the other hand, when the difference between the reception intensity of the loop antenna 40 and the reception intensity of the rear glass antenna 50 does not exceed the predetermined range, the reception of the radio wave from the antenna is not greatly disturbed. The control unit 160 can operate the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

Here, the preset range is a reference range for changing the antenna between the single mode and the diversity mode. For example, the range may be 0 to 5 db.

That is, when the reception strength of the loop antenna 40 and the rear glass antenna 50 exceeds 5 db, the controller 160 stops the operation of the loop antenna 40 and operates the rear glass antenna 50 in the single mode . On the other hand, when the difference in the reception intensity is within 5 db and not within 5 db, the controller 160 can operate the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

In addition, the preset range is not limited to 5 db, but may be set in various ranges depending on the use environment and its purpose.

In addition, after the rear glass antenna 50 is operated in the single mode, the controller 160 may not change the operation mode for a preset time period to prevent a ping-pong phenomenon that may occur between the single mode and the diversity mode.

The predetermined time may be set within a range of 1 minute to 5 minutes, but is not limited to this time, and may be set to various time ranges depending on the use environment and the purpose thereof.

The control unit 160 sets the operation mode of the loop antenna 40 and the rear glass antenna 50 to the single mode or the diversity mode based on the operation of the rear glass wiper 53 provided on the rear glass 18 Can be changed.

When the rear glass wiper 53 is in operation, the radio wave receiving capability of the rear glass antenna 50 may be deteriorated due to noise generated in the rear glass wiper 53. Therefore, in this case, the controller 160 stops the operation of the rear glass antenna 50 and operates the loop antenna 40 in the single mode.

On the other hand, when the rear glass wiper 53 is not in operation, no noise is generated in the motor of the rear glass wiper 18, so that reception of the rear glass antenna 50 is not affected. Accordingly, in this case, the controller 160 can operate the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

The control unit 160 can change the operating modes of the loop antenna 40 and the rear glass antenna 50 by differentiating the reception intensity of the radio waves from the loop antenna 40 and the rear glass antenna 50. [

Specifically, the radio wave reception intensity of the loop antenna 40 and the radio wave reception intensity of the rear glass antenna 50 are measured. If the difference of the reception intensity exceeds the preset range, the operation of the rear glass antenna 50 is stopped And the loop antenna 40 can be operated in the single mode.

On the contrary, when the difference between the reception intensity of the loop antenna 40 and the reception intensity of the rear glass antenna 50 does not exceed the preset range, the control unit 160 controls the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

The preset range refers to a range in which the antenna is used as a reference for changing the single mode and the diversity mode, and may be, for example, 0 to 5 db. That is, when the reception strength of the loop antenna 40 and the rear glass antenna 50 exceeds 5 db, the controller 160 stops the operation of the rear glass antenna 50 and operates the loop antenna 40 in the single mode .

On the other hand, when the difference in the reception intensity is within 5 db and not within 5 db, the controller 160 can operate the loop antenna 40 and the rear glass antenna 50 in the diversity mode.

However, the preset range is not limited to 5 db, and may be set in various ranges depending on the use environment and its purpose.

In addition, after the loop antenna 40 is operated in the single mode, the control unit 160 may not change the operation mode for a preset time period to prevent a ping-pong phenomenon that may occur between the single mode and the diversity mode.

The predetermined time may be set within a range of 1 minute to 5 minutes, but is not limited to this time, and may be set to various time ranges depending on the use environment and the purpose thereof.

The control unit 160 may change the operation modes of the loop antenna 40 and the rear glass antenna 50 based on the travel information of the vehicle 100 received from the navigation terminal 150. [ A detailed description thereof will be described later with reference to FIG.

In addition, the control unit 120 includes a memory (not shown) for storing data for a program reproducing an algorithm or algorithm for controlling the operation of components in the vehicle 100, and a memory (Not shown) for performing the above-described operations. At this time, the memory and the processor may be implemented as separate chips. Alternatively, the memory and the processor may be implemented in a single chip.

Also, at least one component may be added or deleted corresponding to the performance of the components of the vehicle 100 shown in Fig. It will be readily understood by those skilled in the art that the mutual position of the components can be changed corresponding to the performance or structure of the system.

Thereafter, it is possible to detect whether or not the electronic device obstructing the reception of the radio wave of the loop antenna 40 is operated (S110)

Although the electronic device is described as a rear camera in Fig. 7, the electronic device is not limited thereto, and if an electronic device that hinders the reception of the radio wave of the loop antenna 40 is provided in the vicinity of the loop antenna 40, have.

If the rear camera is not operating, it is not influenced by the reception of the radio wave of the loop antenna 40. Therefore, the procedure returns to the first step. (S120)

However, if the rear camera is in operation, noises are generated due to the operation of the rear camera and affect reception of the radio wave of the loop antenna 40. In this case, the vehicle 100 stops the operation of the loop antenna 40 It is possible to operate the antenna by setting the rear glass antenna 50 to the single mode. (S130)

After operating the rear glass antenna 50 in the single mode, it may not change the operation mode for a predetermined time period to prevent a ping-pong phenomenon that may occur between the single mode and the diversity mode. (S140)

Referring to FIG. 8, the vehicle 100 can operate the antenna in a diversity mode to efficiently receive radio waves from an external server. (S200)

Specifically, the loop antenna 40 and the rear glass antenna 50 can be operated in a diversity mode to receive radio waves from an external server.

Thereafter, it is possible to detect whether or not the electronic device obstructing the reception of the radio wave from the rear glass antenna 50 operates. (S210)

8, the electronic device is described as a motor provided in the rear glass wiper 53. However, the present invention is not limited thereto. The electronic device is provided in the vicinity of the rear glass antenna 50 which hinders the reception of the radio wave from the rear glass antenna 50 Such electronic devices may also be included therein.

The operation of the rear glass wiper 53 is detected, and if the rear glass wiper 53 is not in operation, it does not affect the reception of the rear glass antenna 50, so the process returns to the first step. (S220)

However, if the rear glass wiper 53 is in operation, noise is generated due to the operation of the rear glass wiper 53, which affects the reception of the rear glass antenna 50. In this case, The operation of the glass antenna 50 can be stopped and the loop antenna 40 can be operated in the single mode to operate the antenna. (S230)

After operating the loop antenna 40 in the single mode, the operation mode may not be changed for a predetermined time period to prevent a ping-pong phenomenon that may occur between the single mode and the diversity mode. (S240)

9 is a flowchart showing a control method of a vehicle according to another embodiment.

Referring to FIG. 9, the vehicle 100 can detect whether the rear glass wiper 53 obstructing the reception of the radio wave from the rear glass antenna 50 is operating. (S300)

The operation of the rear glass wiper 53 is detected, and if the rear glass wiper 53 is not in operation, it does not affect the reception of the rear glass antenna 50, so the process returns to the first step. (S310)

However, if the rear glass wiper 53 is in operation, noise is generated due to the operation of the rear glass wiper 53, which affects the reception of the rear glass antenna 50. In this case, The operation of the glass antenna 50 can be stopped and the loop antenna 40 can be operated in the single mode to operate the antenna. (S320)

Thereafter, the vehicle receives driving information of the vehicle from the navigation terminal 150 and determines whether the vehicle has entered the tunnel based on the received information. (S330, S340)

If the vehicle 100 does not enter the tunnel, it returns to the first stage, and if it is determined that the vehicle 100 has entered the tunnel, it is not necessary to operate the rear window wiper 53 in the tunnel. Therefore, in this case, even when the rear glass antenna 50 is operated, the vehicle 100 is not affected by the noise of the rear glass wiper 53, so that the vehicle 100 stops the operation of the rear glass wiper 53 in order to efficiently receive the airwaves The antenna can be operated in the diversity mode. (S350)

Thereafter, if it is determined that the vehicle 100 is out of the tunnel, the rear windshield wiper 53 can be operated again and the loop antenna 40 can be operated in the single mode. (S360, S370)

The configuration of the vehicle 100 and the method of controlling the vehicle 100 according to one embodiment have been described so far.

In the case of the conventional invention, the diversity mode is uniformly applied without considering the noise generated by the camera and the operation of the wiper, so that there is a problem that the wave can not be efficiently received.

However, since the vehicle 100 according to the embodiment changes the mode of the antenna depending on whether the camera and the wiper that affect the antenna operate, the reception performance of the antenna can be improved more efficiently.
