Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is a flowchart showing steps of the present invention. Referring to FIG. 1, a first step (SlOO) in which a vehicle AVN and a first user terminal are mirrored with each other is performed. For example, in the first step S100, the first user terminal is connected to the vehicle AVN by wire, and the data communication is performed based on the android open accessory protocol (AOAP) between the first user terminal and the vehicle AVN through the wired connection, And requesting and receiving the wireless communication connection information of the terminal and the identification information of the first user terminal from the first user terminal.

The wired connection is preferably a cable capable of data communication. The risk of the user's password being leaked through the wired connection is significantly lowered.

Data communication is performed based on the AOAP (android open accessory protocol) between the user terminal and the vehicle AVN through the wired connection. At this time, APP (apple accessory protocol) may be used as a protocol used between the first user terminal and the vehicle AVN.

Here, the wireless communication connection information of the first user terminal includes any one of an access point (AP) name, a MAC address, or an IP address of a first user terminal and a wireless communication connection password. The wireless communication connection password may be a binary code or a text format, but may be a password using a different encryption scheme such as a binary code, and may be encrypted to improve the security level or may be a simple text format for the convenience of the user. The identification information of the first user terminal may be included in the identification information of the first user terminal, as long as it includes the unique identification number of the terminal as well as the unique information of the terminal. The reason why the identification information of the terminal is transmitted to the AVN for the vehicle is that when a plurality of user terminals attempt to connect with the AVN for the vehicle, the identification information of each user terminal stored in the AVN for the vehicle, It is easy to decide.

The AVN of the vehicle is detected and the wireless network signal of the first user terminal located in the vicinity of the vehicle AVN coinciding with the wireless communication connection information of the first user terminal and the identification information of the first user terminal, Connection is performed, and the vehicle AVN and the first user terminal are mirrored with each other.

Mirroring is a connection between a vehicle AVN and a first user terminal by a wired or wireless communication connection between applications implemented through a software development kit (SDK). At this time, the application included in the vehicle AVN requests at least one of the content, the program or the application to be mirrored to the first mirroring application of the first user terminal, and the first user terminal receiving the request transmits the mirroring to the vehicle AVN And outputs the above-described content, program, or application.

The first user terminal requests and receives the first wireless communication connection information and the second user terminal identification information from the first user terminal to the second user terminal, Step S200 is performed.

A third step of controlling the first user terminal to request content selection to the second user terminal so that the vehicle AVN and one or more second user terminals are mirrored to each other and to transmit the selected content to the vehicle AVN via the first user terminal (S300) is performed.

The content transmitted to the vehicle AVN may be the content transmitted from the plurality of second user terminals, and the plurality of contents may be outputted singly, all or selectively multiple of the vehicle AVN.

The content transmitted to the vehicle AVN may be transmitted including the content of the first user terminal. When the second user terminal is performing mirroring, the mirroring function of the first user terminal may be limited or not limited. This is controllable from the vehicle AVN.

The first wireless communication connection information includes any one of an access point (AP) name, a MAC address, and an IP address of a second user terminal and a wireless communication connection password.

The wireless communication connection password may be in binary code or text format. The details of the first wireless communication connection information are omitted.

After performing the third step S300, at least one of the number of times of wireless communication connection or the time of wireless communication connection between the vehicle AVN and one or more second user terminals is distinguished into the identification information of the second user terminal by the first user terminal Can be stored as ranking information. This is for granting a connection access right in order to prevent connection crosstalk when a plurality of user terminals are mirrored to a vehicle AVN.

That is, the first user terminal and the second user terminal, which are wirelessly communicatively connected to the vehicle AVN, may be single or plural, and may determine the connection priorities of the plurality of user terminals using the priority information, The terminal and the car AVN can be connected to the wireless communication automatically. In this case, not only the number of times of wireless communication connection or the time of wireless communication connection but also the terminal specified by the user is designated as a favorite and the other terminal attempts mirroring to the vehicle AVN, the terminal designated by the user can have access privilege preferentially .

Using the priority information, the first user terminal determines the connection priority order of the second user terminal, transmits the content after first connecting the second user terminal to the vehicle AVN via the first user terminal by wireless communication.

In a third step, the first user terminal is connected to a second mirroring application of a second user terminal that is compatible with the first mirroring application of the first user terminal so that the second mirroring application can select the content and send it to the first mirroring application request. Or the first mirroring application may remotely select and transmit the content of the second user terminal to the vehicle AVN.

The first user terminal and the second user terminal may include a communication device such as a cellular phone, and the AVN for a vehicle may be a navigation device or a vehicle display device. In addition, the identification information of the second user terminal may be included in the identification information of the second user terminal, as long as the identification information of the second user terminal includes not only the unique identification number of the terminal but also unique information of the terminal.

At this time, applications that can be mirrored between the vehicle AVN and the first user terminal or the second user terminal may be compatible with each other based on the SDK.

In addition, the concept of multi-mirroring of the present invention is that the first user terminal is mirrored to the vehicle AVN first by acting as a bridge, and that one or more second user terminals are mirrored with the vehicle AVN through wireless communication with the first user terminal it means.

Meanwhile, not only the first user terminal but also the second user terminal may serve as a bridge. When the second user terminal acts as a bridge, the third user terminal and the vehicle AVN are mirrored. In more detail, after performing the third step (S300), the second user terminal requests and receives the second wireless communication connection information and the identification information of the third user terminal from one or more third user terminals, The third user terminal is wirelessly connected, the second user terminal sends a content selection request to the third user terminal so that the vehicle AVN and one or more third user terminals are mirrored to each other, the selected content is transmitted to the second user terminal, The first user terminal requests content selection to the second user terminal, and controls the selected content to be transmitted to the first user terminal and transmitted to the vehicle AVN, so that the multi-bridge mirroring function can be performed.

2 is a diagram illustrating a method of multi-mirroring according to the present invention. Referring to FIG. 2, the vehicle AVN and the first user terminal and / or the second user terminal are mirrored.

More specifically, the embodiment will be described in detail.

(Example)

Connect the USB cable to the USB port of your phone and navigation device to mirror the phone screen to the car navigation system. Simultaneously with the connection, the mobile phone carries out the request for the wireless communication connection information and the identification information of the mobile phone from the navigation device to the mobile phone.

In response to the wireless communication connection information request, the first mobile phone transmits either the access point name, the MAC address, or the IP address of the first mobile phone, the wireless communication connection password, and the identification information of the first mobile phone to the navigation device do.

As a result, since navigation has received wireless connection information for the first mobile phone by wire, future navigation and the above-described first mobile phone can be automatically connected wirelessly.

In this state, the first mobile phone and the navigation device are mirrored, so that the screen output for using the first mobile phone is simultaneously performed in the navigation system. At this time, the navigation records and stores the mirroring connection time and the connection count for the first mobile phone being mirrored, and when the at least one first mobile phone attempts a mirroring connection in the future, the navigation device grants the first connection right according to the above-described criteria.

Thereafter, at least one second mobile phone connected to the first mobile phone by radio is provided.

When the first mobile phone and the second mobile phone are connected, the first mobile phone requests the second mobile phone to select the content included in the second mobile phone, and controls the selected content to be transmitted to the navigation via the first mobile phone. At this time, the content may be transmitted while the first mobile phone and the second mobile phone are connected by mirroring, or the content of the second mobile phone may be transmitted to the navigation device even when the first mobile phone is disconnected from the mirroring connection with the navigation.

Further, when one or more second mobile phones are mirrored to the first mobile phone, they may be connected singly or a plurality of them may be connected at the same time. When the mirroring of the second mobile phone and the navigation is completed, each of the second mobile phones is divided into identification information of the second mobile phone through at least one of the number of wireless communication connection times or the wireless communication connection time, And stores it as priority information.

When the second mobile phone having the same identification information requests the connection to the navigation, the first mobile phone determines the connection priority order of the second mobile phone using the stored priority information, and transmits the first mobile phone to the first mobile phone via the first mobile phone And transmits contents after connecting with wireless communication through navigation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Various changes and modifications will be possible.
