Abstract

The present invention relates to a vehicle data communication module. This module constitutes a vehicle data communication system together with a display main body and an audio device, and transmits data output from removable memory, connected to the module, to the main body. In detail, the vehicle data communication module is arranged to be spaced apart from the main body and is provided with a USB port formed in a portion thereof. The vehicle data communication module includes a data transmission unit designed to allow USB memory and an SD card to be detachable from the data transmission unit, and a charging unit designed to be capable of charging a mobile device. The data transmission unit and the charging unit are processed to be integrated into a single box or a single casing and are mounted in the vehicle.

Claims

1. A vehicle data communication module, the module constituting a vehicle data communication system together with a display main body installed in a vehicl and an audio device configured to receive a signal from the main body and output the signal as an audible sound, and transmitting data output from removable memory connected to the module to the main body, wherein:

the vehicle data communication module is arranged to be spaced apart from the main body and is provided with a Universal Serial Bus (USB) port formed in a portion thereof, the vehicle data communication module comprising;

a data transmission unit provided with a Secure Digital (SD) port formed on a side of the USB port and designed to allow USB memory and an SD card to be detachable from the data transmission unit; and

a charging unit provided with a charging port formed in a portion of the module and designed to be capable of charging a mobile device,

wherein the charging unit includes a charging port, to which a mobile device to be charged or a medium for providing an exclusive charging program only for a corresponding device is connected, a first interface unit for generating a signal depending on a connection to the charging port, a microcomputer for recognizing the signal as a ‘

charging’

signal or a ‘

download’

signal and operating such that charging power is supplied or a charging program is downloaded from the medium, and a power unit for providing charging power required to charge the device from power of the vehicle depending on an operation of the microcomputer, and

wherein the data transmission unit and the charging unit are processed to be integrated into a single module box or a single casing and are mounted in the vehicle, with the respective ports exposed to outside of the module.

2. The vehicle data communication module of claim 1, wherein the data transmission unit comprises:

an input unit including the USB port and the SD port;

a second interface unit for transmitting data of the SD card based on a USB standard;

a USB hub for enabling data communication based on the USB standard to be performed between the individual ports and the main body; and

an output port for transmitting data from the USB hub to the main body.

3. The vehicle data communication module of claim 2, wherein the output port is a single port based on the USB standard, and uses a 4-pin type.

4. The vehicle data communication module of claim 2, wherein the second interface unit comprises:

a USB 2.0 physical layer interface (PHY) for enabling data transmission to be performed in accordance with a signal level between the main body and a USB link;

the USB link for enabling data communication to be performed between the USB 2.0 PHY and an SD card control unit in conformity with a USB communication protocol therebetween;

the SD card control unit provided subsequent to the USB link and configured to perform data communication between the SD card and the main body; and

a main control unit for controlling an overall operation of the second interface unit.

5. The vehicle data communication module of claim 1, wherein the first interface unit is functionally implemented as a circuit of the microcomputer.

6. The vehicle data communication module of claim 1, wherein the charging port is a USB port.

7. The vehicle data communication module of claim 1, wherein the microcomputer comprises memory for storing data about the mobile device or data about downloading of a charging program.

8. The vehicle data communication module of claim 1, wherein:

the USB port is connected to the first interface unit,

when the medium is connected to the USB port, the first interface unit generates a connection signal, and

the microcomputer recognizes the connection signal as a ‘

download’

signal.

9. The vehicle data communication module of claim 1, wherein:

the USB port is connected to the first interface unit through the main body or the audio device,

when the medium is connected to the USB port, the first interface unit generates a connection signal as the main body or the audio device transmits or passes a charging program, and

the microcomputer recognizes the connection signal as a ‘

download’

signal.
