The present invention relates to an apparatus and method for controlling mirroring between a vehicle device and a mobile terminal. More specifically, it relates to an apparatus and method for controlling mirroring between a vehicle device and a mobile terminal in a vehicle.

According to the WiFi standard specification, WiFi connection is defined as being automatically connected to the last connected device. In addition, when the last connected device is not found, it is defined as automatically connected in the order of the connected time among the remaining devices.

Most of the prior art related to WiFi connection such as Korean Patent Publication No. 2011-0068465 and US Patent Publication No. 2013-0336161 focus only on how to access the Wi-Fi network and how to control it. It does not include information on which devices are automatically connected in a special environment.

The definition of the WiFi technical specification that always automatically connects to the last connected device is not appropriate in the vehicle environment. The use of WiFi in the vehicle is made through the mobile phone of the driver and each occupant, but the driver may change from time to time due to the characteristics of the vehicle. Even though the driver has changed, if the last connected device and WiFi are automatically connected, a problem arises in terms of usability.

The present invention has been conceived to solve the above problem, and an object of the present invention is to propose a mirroring control apparatus and method for a vehicle using priority for controlling mirroring between a vehicle device and a mobile terminal in a vehicle using priority.

However, the object of the present invention is not limited to the above-mentioned matters, and other objects not mentioned will be clearly understood by those skilled in the art from the following description.

Preferably, the priority determining unit gives a higher priority as the first order or the second order is delayed.

Preferably, the priority determination unit comprises: a registration determination unit that determines whether the detected device is registered; And if it is determined that the detected device is registered, the priority is determined with respect to the detected device based on information stored in the database, and if it is determined that the detected device is not registered, the detected device is assumed to be It includes a registration criterion priority determining unit that determines the high priority.

Preferably, the priority determination unit determines the priority based on the detected signal strength of the device.

Preferably, the priority determination unit determines the priority based on the signal strength when the priority cannot be determined for at least two devices based on information stored in the database.

Preferably, the vehicle device is an Audio Video Navigation (AVN) system, and the device is a mobile terminal.

Preferably, the mirroring control unit controls the first mirroring or the second mirroring using WiFi or Bluetooth.

In addition, the present invention includes the steps of detecting at least one device located within a predetermined distance from the vehicle device; Calculating the number of detected devices; Determining a priority for each device if the number of detected devices is at least two; And if the number of detected devices is at least two, a first mirroring between the selected device and the vehicle device is controlled according to the priority. If the number of detected devices is one, the detected device and the vehicle device A method of controlling mirroring for a vehicle using priority, comprising the step of controlling the second mirroring between the two, is proposed.

The present invention can obtain the following effects by controlling the mirroring between the vehicle device and the mobile terminal in the vehicle using the priority.

First, it is possible to improve user convenience. For effective use of mirroring technology, it is better to automatically connect to the device the user wants (usually the device the driver carries) than to automatically establish a Wi-Fi connection to the last connected device. This is because the mirroring technology is a technology that displays the mobile phone screen on the AVN screen as it is, and will be widely used as a substitute for navigation. The present invention relates to a connection method in which a priority device is set and the device is connected with the highest priority, and user convenience may be improved through this method.

First of all, in adding reference numerals to elements of each drawing, it should be noted that the same elements have the same numerals as possible even if they are indicated on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, a preferred embodiment of the present invention will be described below, but the technical idea of the present invention is not limited or limited thereto, and may be modified and variously implemented by a person skilled in the art.

Conventionally, the focus is only on how to connect to a device using WiFi, and it does not include concerns about which device to connect to in a special space such as a vehicle.

The present invention relates to Mirrorcast Mirroring using WiFi, and relates to a technology for displaying a mobile phone screen on an AVN display as it is. The present invention is characterized in that the last connected device is not always automatically connected, but is automatically connected to the current driver's mobile phone.

1 is a conceptual diagram showing the internal configuration of a WiFi automatic connection system according to an embodiment of the present invention.

Vehicle-phone Wi-Fi Mirrorcast Mirroring and interlocking technology is a technology that shows the screen of a mobile phone on an AVN display using Wi-Fi communication.

According to the definition described in the existing Wi-Fi standard specification, a Wi-Fi device is automatically connected to the last connected device. However, a special place called a vehicle is different from the existing main Wi-Fi communication environment. This is because both the driver and the occupant have a cell phone in a small space, and the driver can change from time to time.

In order to use the mirroring technology more effectively, it is better to automatically connect to the device the user wants (mainly the device the driver carries) rather than automatically connect to the last connected device.

In the present invention, a connection method in which the device is connected with the highest priority by setting a priority device in some cases, instead of being automatically connected to the last connected device according to the conventional method will be described.

Hereinafter, it will be described in more detail with reference to FIG. 1.

The WiFi automatic connection system 100 includes audio video navigation (AVN) 110 and devices 151, 152, 153, and 154.

The AVN 110 has a large image output device (LCD) because it performs various multimedia functions. For example, the AVN 110 may have an image output device of 7 inches or more.

Devices 151, 152, 153, and 154 refer to mobile terminals held by persons in a vehicle. The devices 151, 152, 153, and 154 are devices that are frequently used by the user regardless of whether or not a user is boarding a vehicle, and provide familiar screens and information. However, since most of the devices 151, 152, 153, and 154 have a smaller screen than the AVN 110, it is inconvenient to use while driving.

The present invention (vehicle-phone Wi-Fi mirrorcast mirroring and interworking technology) was conceived to solve this inconvenience. It is to conveniently provide screens and information.

In FIG. 1, the AVN 110 is shown to include only configurations related to WiFi Miracast Mirroring, but the AVN 110 in this embodiment is not limited to including these configurations.

The AVN 110 includes an image output device 120, a mirrorcast control device 130, and a Wi-Fi communication device 140.

The image output device 120 refers to an LCD mounted on the AVN 110. The image output device 120 performs a function of displaying the same screen to the user as the screen of the devices 151, 152, 153, and 154. The screen displayed on the image output device 120 is provided by the mirror cast control device 130.

The mirrorcast control device 130 performs a function of processing a signal received through the Wi-Fi communication device 140 and displaying it on the image output device 120. In addition, the mirrorcast control apparatus 130 determines which device to automatically connect to Wi-Fi and performs a function of performing automatic connection.

The mirrorcast control device 130 includes a mirrorcast processing unit 131, a Wi-Fi signal processing unit 132, an automatic Wi-Fi connection unit 133, and a priority DB 134.

The mirrorcast processing unit 131 performs a function of actually performing mirrorcast mirroring using the processed Wi-Fi signal and transmitting the result of the execution to the image output device 120.

The Wi-Fi signal processing unit 132 performs a function of sending a Wi-Fi signal through the Wi-Fi communication device 140 and performs a function of processing a signal received from the Wi-Fi communication device 140 into data. .

The automatic Wi-Fi connection unit 133 determines which device is attempting to automatically connect to among the devices 151, 152, 153, and 154 found in the vehicle, and executes automatic connection with the corresponding device according to the determination result. Performs a function. In addition, the automatic Wi-Fi connection unit 133 may also perform a function of setting a priority device. A more detailed description of this will be described later with reference to FIG. 2.

The priority DB 134 is a database that stores and manages devices set as priority devices. The automatic Wi-Fi connection unit 133 may access the priority DB 134 to modify data.

The Wi-Fi communication device 140 transmits an actual Wi-Fi wireless communication signal and transmits the received signal to the mirrorcast control device 130.

Devices 151, 152, 153, and 154 refer to devices that are searched in a vehicle. Devices 151, 152, 153, and 154 generally refer to mobile phones. There may be drivers and passengers in the vehicle, and since most of them have mobile phones, there is a high probability that there is more than one device (151, 152, 153, 154) searched in the vehicle.

FIG. 2 is a conceptual diagram illustrating an internal configuration of an automatic WiFi connection unit constituting the automatic WiFi connection system shown in FIG. 1.

The automatic Wi-Fi connection unit 133 is located in the mirrorcast control device 130 on the automatic Wi-Fi connection system 100 described in FIG. 1. The automatic Wi-Fi connection unit 133 sets a priority device and performs a function of actually performing automatic connection according to the connection state.

The above-described operation of the automatic Wi-Fi connection unit 133 is performed through each module shown in FIG. 2, and details are as follows.

The priority learning module 203 serves to set a priority device. 3 is a reference diagram for explaining a function of a priority learning module constituting the automatic WiFi connection unit shown in FIG. 2.

When a new device is connected via Wi-Fi, that is, when a device not registered in the AVN 110 is connected, the priority learning module 203 asks the user whether to set the device as a priority device through a pop-up. In this case, as shown in FIG. 3, when device 1 151 is registered as a priority device, it is accumulated in the priority queue 160. In the Priority Queue 160, it is determined that the recently registered device has a higher priority, and attempts to connect it first at the time of actual connection.

On the other hand, whether or not to set the priority device can be set using an automated algorithm in addition to using a pop-up for a new device connection.

The automated algorithm prioritizes the signal strength of the Wi-Fi device when attempting a vehicle, and if the difference in signal strength is not large, it refers to determining the priority device according to the past history, such as the time and place (GPS) when the vehicle started.

The automated algorithm is a method to automatically connect the driver's device as much as possible, and works when the user does not directly set the priority device. A more detailed description of the automated algorithm will be described later with reference to FIG. 4.

The connection status check module 201 determines whether or not a Wi-Fi is currently connected, and if it is determined that it is not connected, checks for some reason whether automatic connection processing should be performed.

Automatic connection processing is required when AVN is booted, when link loss occurs, when connection is disconnected by a device, and so on. Each processing proceeds in the automatic connection processing module 202.

The automatic connection processing module 202 performs a function of executing a Wi-Fi automatic connection when an actual Wi-Fi automatic connection should occur.

1. AVN booting: ① Priority Device → ② Last Connected Device → ③ Others

During AVN booting, the automatic connection processing module 202 first attempts to connect the Priority Device. AVN booting means starting a vehicle, and the automatic connection processing module 202 first attempts to connect an important device set as a priority device (①). If the Wi-Fi of the Priority Device is turned off or is not located in the vehicle, the automatic connection processing module 202 attempts to connect the last connected device (②). If it is not possible to connect even the last connected device, the automatic connection processing module 202 tries to connect in the order of signal strength among the remaining registered devices (③).

2. In case of Link Loss: ① Last Connected Device → ② Others

Link Loss refers to a state in which the Wi-Fi connection is disconnected due to a weak signal due to reasons such as increasing the distance between devices. In this case, since the last connected device is more important than the priority device, the automatic connection processing module 202 tries to connect the last connected device first (①). When the connection fails, the automatic connection processing module 202 tries to connect in the order of signal strength among the remaining registered devices (②).

3. When disconnecting: ① Last Connected Device → ② Others

Even if the connection is temporarily disconnected due to an error in the device, the automatic connection processing module 202 first attempts to connect the last connected device (①) as in the case of Link Loss. When the connection fails, the automatic connection processing module 202 tries to connect in the order of signal strength among the remaining registered devices (②).

4 is a flowchart illustrating a method of operating a WiFi automatic connection system according to an embodiment of the present invention.

When the vehicle is turned on, the Priority learning module 203 starts WiFi connection (S410).

Thereafter, the priority learning module 203 detects the strength of the WiFi signal for each device (S420).

Thereafter, the priority learning module 203 detects two devices with the highest signal based on the signal strength (S430). In the present example, it has been described that two devices are detected, but the number of devices detected in step S430 in the present invention is not limited to two.

Thereafter, the priority learning module 203 compares the signal strengths of the two devices to determine whether the difference value of the signal strengths of the two devices is greater than or equal to a reference value (S440).

When it is determined that the difference value of the signal strength between the two devices is greater than or equal to the reference value, the priority learning module 203 selects the device with the highest signal strength as the priority device (S450). On the other hand, if it is determined that the difference value of the signal strength between the two devices is less than the reference value, the priority learning module 203 selects a priority device based on the past history according to external factors (time, place, etc.) (S460).
