Hereinafter, a communication system installed in a vehicle will be schematically described with reference to FIG.

1, the vehicle 10 has a communication system 100 inside the vehicle.

The communication system 100 may communicate with the telematics center 300 using mobile communication technology.

The communication system 100 includes a communication module 110 (e.g., a modem). The communication system 100 is connected to the telematics center 300 via a telematics center 300 for remote control (e.g., remote start, remote door lock / unlock, remote air conditioning, vehicle status inquiry, vehicle position inquiry, horn status inquiry, Emergency calls can be provided.

A mode in which the communication system 100 uses or can use the communication module 110 is defined as a modem mode.

In addition, the communication system 100 can communicate with the mobile terminal 200. The communication system 100 may be connected to the mobile terminal 200 by wire, and the communication system 100 may be connected to the mobile terminal 200 through wireless communication (e.g., Bluetooth, WiFi, NFC, ZigBee).

A mode in which the communication system 100 communicates with the mobile terminal 200 via wire or wireless communication without using the communication module 110 is defined as a connection mode.

Also, according to the development of the technology, the communication system 100 may be connected to the mobile terminal 200 through mobile communication.

In this specification, the telematics center 300 is described as an example, but a VCRM system (vehicle electric field management system) may be employed instead of a telematics center.

The communication system 100 can download the SW required for driving the communication system 100 from the center 300. [ The communication system 100 can download the corresponding SW through FOTA, but the present invention is not limited thereto.

The communication system 100 can not use the communication module when installing the SW required for driving. That is, the communication system 100 can not be driven in the modem mode. Then, the telematics service can not be used through the communication module 110.

In this case, after the communication system 100 is connected to the mobile terminal 200 in the connectivity mode, the communication system 100 can receive the telematics service from the center 300 using the communication module provided in the mobile terminal 200.

That is, the communication system 100 can be provided with a telematics service using the communication module of the mobile terminal 200 while operating in the connectivity mode. For example, the communication system 100 may receive an emergency call service, a remote air-conditioning service, a location information notification service, and the like through the mobile terminal 200.

For this, the communication system 100 may be configured to be in a connectivity mode immediately after downloading all SWs required for driving, or when the signal of the communication module 110 is weak (for example, when the communication module 110 fails) (A pairing in the case of Bluetooth and a communication connection in the case of Wi-Fi) with the mobile terminal 200 in order to operate.

Then, when the communication system 100 is difficult to drive in the modem mode, such as the above-described example (installation of SW for driving, failure of the communication module 110, etc.), the communication system 100 immediately switches the mode to the connectivity mode to seamlessly provide the telematics service Can receive.

2 is a block diagram of a vehicle-mounted communication system 100 according to an embodiment.

2, the communication system 100 may include a communication module 110, a connectivity interface 120, a memory 130, and a controller 140. The communication system 100 may include more components, but components that are not necessary for the description will be omitted.

The communication module 110 performs communication with the center 300. Specifically, the communication module 110 can communicate with the center 300 through a mobile communication network.

The connectivity interface 120 is a component for communicating with the external terminal 200 through wire / wireless communication.

The memory 130 stores data necessary for the communication system 100. [

The control unit 140 corresponds to a module that controls the communication system 100 as a whole.

The center 200 is typically a telematics center, but may include Vehicle Customer Relationship Management (VCRM).

The control unit 140 may control the communication system 100 to operate in a modem mode or a connectivity mode. The communication system 100 may receive a service (e.g., a telematics service) by communicating with the center 300 through the communication module 110 in a modem mode. The communication system 100 can receive services by communicating with the center 300 through the mobile terminal 200 in the connectivity mode. The communication system 100 can not receive the telematics service from the center 300 through the communication module 110 in the connectivity mode.

The control unit 140 may determine the possibility that the communication module 110 is inactivated when the communication system 100 is driven in the modem mode.

Here, the state in which the communication module 110 is deactivated means a state in which the communication module 110 can not communicate with the center 300 through the communication module 110 (for example, a failure of the communication module 110, installation of firmware, etc.).

The possibility of deactivation implies that there is room for deactivation. For example, it is possible that the communication module 110 may be inactivated when the firmware is downloaded and before installation, or when the signal strength of the communication module 110 is weak (for example, -110 dBm or less). However, It is not limited thereto.

The control unit 140 may perform setup for driving in the connectivity mode if the communication module 110 is likely to be inactivated. That is, the control unit 140 can perform setup by pairing with the mobile terminal 200 in the case of Bluetooth and acquiring communication authority of the mobile terminal 200 in the case of Wi-Fi. If communication is not required, the process may be omitted.

In a case where the communication module 110 is in a deactivated state, the control unit 140 can set the communication system 100 in the connectivity mode.

The control unit 140 can receive a service from the center 300 using the mobile terminal 200 as a modem in the connectivity mode.

Then, the control unit 140 determines whether there is a possibility that the communication module 110 is activated again. In this case, the control unit 140 may change to the modem mode and receive a service from the center 300 through the communication module 110. [

3 is a flowchart showing a method of driving a communication system according to an embodiment. Will be described with reference to the reference numerals of FIG.

Once the module mode is activated (S310), the controller 140 determines whether there is a possibility that the communication module is disabled (S320).

For example, if the FOTA download of the communication module 110 is completed, the control unit 140 may determine that the communication module 110 is inactivated if the signal strength of the communication module 110 is less than a predetermined value .

If there is a possibility that the communication module is inactivated, the control unit 140 performs a setup for driving in the connection mode (S330).

Then, it is determined whether the communication module is actually inactivated (S340).

If the communication module is not recognized, if the communication module is not being recognized, if the communication module is in the FOTA installation, if the communication module is in an error during installation of the SW in FOTA, if the communication module is in No-Service, (E.g., an antenna failure) is detected, the communication module 110 may be determined to be in a deactivated state, but the present invention is not limited thereto.

If the communication module is in the inactive state, the control unit 140 changes to the connection mode (S350).

Then, the control unit 140 determines whether there is a possibility that the communication module is activated in order to determine whether to terminate the connectivity mode during the connection mode (S360).

For example, if the firmware update (installation) of the communication module is completed, if the communication module and the antenna are normally recognized, the control unit 140 may activate the communication module if the communication module and the antenna are normally recognized It can be judged.

Fig. 4 is a diagram showing a screen for selecting one to be operated in the connectivity mode.

This screen is a diagram showing steps to be placed between steps S320 and S330

That is, if the control unit 140 determines that there is a possibility that the communication module 110 is inactivated, the control unit 140 can wait for user selection before performing the setup for driving in the connectivity mode.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.

The method according to the above-described embodiments may be implemented as a program to be executed by a computer and stored in a computer-readable recording medium. Examples of the computer-readable recording medium include a ROM, a RAM, a CD- , A floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional program, code, and code segments for implementing the above-described method can be easily inferred by programmers in the technical field to which the embodiment belongs.
