The GPS may receive position signals from a plurality of GPS satellites to calculate its own position (that is, a current position of the vehicle 1), and transmit information about the calculated position to the communication unit. Also, the GPS may include a GPS antenna (not shown) to receive satellite signals from the GPS satellites, an accelerometer (not shown) to measure acceleration of the vehicle 1, and an orientation sensor (not shown) to sense orientation of the vehicle 1. The GPS may transmit acceleration data and orientation data, in addition to information about a current position of the vehicle, to the communication unit.
[0073] The communication unit of the multimedia player 200 may communicate with the external device 400b and the server through a wired/wireless communication network. The wired/wireless communication network may be a broadcasting network, such as Transport Protocol Expert Group (TPEG) of DMB, Stream X-Machine (SXM), and Radio Data System (RDS). The server may communicate with the multimedia player 200, and if a route search request signal is received from the multimedia player 200, the server may search a route based on a current position of the vehicle 1 and a destination, and transmit information about the found route to the multimedia player 200.
[0074] The multimedia player 200 may further include a sound unit (not shown). The sound unit of the multimedia player 200 may output information about a route and driving information upon route guiding, as sound, and also output sound of music and images selected by a user.
[0075] FIG. 7 is a flowchart chart illustrating a method of controlling a vehicle in which an interface apparatus according to an embodiment of the present disclosure and a multimedia player are installed. The method of controlling the vehicle will be described in detail with reference to FIGS. 6 to 10, below.
[0076] If the vehicle 1 (see FIG. 2) starts, a battery in the vehicle 1 may supply power to various electronic devices in the vehicle 1. At this time, the multimedia player 200 installed in the vehicle 1 may receive operating power, and then, the multimedia player 200 may display a home screen on the display unit.
[0077] Thereafter, if a user selects a function through the home screen, the multimedia player 200 may recognize the selected function and execute the recognized function. For example, if a DMB function is selected by the user, the multimedia player 200 may receive broadcasting signals, and output broadcasting images and broadcasting audio signals as images and sound. If a music play function is selected by the user, the multimedia player 200 may output music play signals as sound.
[0078] The multimedia player 200 may determine whether a navigation function is selected by the user, in operation 501. If the multimedia player 200 determines that the navigation function is selected by the user, the multimedia player 200 may execute the navigation function while displaying operation information for the navigation function. At this time, the multimedia player 200 may communicate with a GPS, and communicate with the interface apparatus 300 to receive map data from the SD card 400a that is a card type memory inserted into the interface apparatus 300. That is, the interface apparatus 300 may transmit, when the multimedia player 200 executes the navigation function, map data stored in the SD card 400a to the multimedia player 200. Transmitting the map data to the multimedia player 200 may include transmitting map data stored in the SD card 400a inserted into the slot part 310 of the interface apparatus 300 to the hub part 315 through a SD communication line. Then, the hub part 315 may switch the SD communication line to a USB communication line, and transmit the map data to the first connector 340a through the USB communication line, and the first connector 340a may transmit the map data to the third connector 251 electrically connected to the first connector 340a through a USB communication line, in operation 502. Then, the third connector 251 provided in the controller 250 of the multimedia player 200 may transmit the map data received from the interface apparatus 300 to the micom 254 of the multimedia player 200.
[0079] Thereafter, the multimedia player 200 may determine whether an external device 400b is connected to the port part 320 when the navigation function is executed, in operation 503. If the multimedia player 200 determines that the external device 400b is connected to the port part 320, the multimedia player 200 may transmit a signal for requesting data communications with the external device 400b to the interface apparatus 300. That is, if a smart phone as the external device 400b is connected to the port part 320 when the map data stored in the SD card 400a is provided, the interface apparatus 300 may transmit data stored in the smart phone 400b to the multimedia player 200 using the second connector 340b and the fourth connector 252 being a USB communication line that is different from the USB communication line of transmitting the map data, in operation 504.
[0080] Herein, transmitting the data stored in the external device 400b to the multimedia player 200 may include transmitting data stored in the external device 400b to the multimedia player 200 so that at least one function among a plurality of functions that are executed on the smart phone as the external device 400b is executed on the multimedia player 200.
[0081] Thereafter, the interface apparatus 300 may transmit and receive data corresponding to the Carplay function between the multimedia player 200 and the external device 400b until the external device 400b is disconnected from the interface apparatus 300, in operation 505.
[0082] As shown in FIG. 8, if the smart phone as the external device 400b is connected to the port part 320, the interface apparatus 300 may enable communications between the multimedia player 200 and the smart phone. That is, the interface apparatus 300 may connect the multimedia player 200 installed in the vehicle 1 to a mobile communication terminal through a USB.
[0083] At this time, the multimedia player 200 may execute only the display function, and actual execution of the corresponding application, data processing, and communication may be executed on the smart phone 400b. Also, the multimedia player 200 may display only a function usable in the vehicle 1, instead of displaying the screen of the smart phone 400b as it is.
[0084] For example, the smart phone 400b may block reception of data for game applications, and transmit music data, video data, messenger applications, and the like, in consideration of a driver's safety, when the Carplay function is executed on the multimedia player 200. Also, when a messenger application is executed, the multimedia player 200 may output content as sound.
[0085] As shown in FIG. 9, if a signal for selecting a navigation function is received, the multimedia player 200 may request map data stored in the card type memory 400a. At this time, the interface apparatus 300 may read map data stored in the card type memory 400a according to the signal for selecting the navigation function through a SD communication line, and switch the SD communication line to a USB communication line to transfer the map data to the multimedia player 200 through the USB communication line.
[0086] If the map data is received, the multimedia player 200 may execute the navigation function using the map data and GPS data, and display operation information corresponding to the navigation function. At this time, the multimedia player 200 may display operation information related to the navigation function on a part of the display unit, and operation information related to another function on the remaining part of the display unit.
[0087] As shown in FIG. 10, if the navigation function is selected when a smart phone is connected to the interface apparatus 300, the multimedia player 200 may display only operation information related to the navigation function.
[0088] Also, if the smart phone is disconnected from the interface apparatus 300, the multimedia player 200 may receive map data through the USB communication line of the interface apparatus 300 to execute the navigation function while displaying only operation information related to the navigation function.
[0089] According to the embodiments of the present disclosure as described above, since the slot part for a card type memory (for example, a SD card), the USB port part, and the AUX terminal are arranged together, it is possible to improve the commercial value and design of the multimedia player (for example, an AVN system).
[0090] Additionally, by providing the slot part into which the card type memory storing map data can be inserted in the interface apparatus, it is possible to improve the design of the interface apparatus, and to ensure a space for a center fascia inside the vehicle. Also, by moving the slot part of the card type memory to a location that is not easily exposed in the interface apparatus, the card type memory can be prevented from being lost. Also, by storing map data in the card type memory, it is possible to reduce a time taken to update the AVN system, and to improve a user's convenience. Also, by switching the communication line of the card type memory to a USB communication line, map data can be provided to the multimedia player even when a mobile communication terminal is connected to the interface apparatus, so that the navigation function can be stably executed on the multimedia player.
[0091] Furthermore, since the slot part of the card type memory and the hub part are designed to be within a distance of 200 mm, an expensive cable for card type memory is not required, which leads to an effective reduction of manufacturing costs.
Thereby, the quality of the interface apparatus and the vehicle can be improved, which leads to improvement of the commercial value of the vehicle. Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
