Abstract

A data processing method of a multimedia terminal for a vehicle includes booting, by an integration micom, a guest operation system according to a wakeup command received from a modem included in the multimedia terminal for the vehicle. The integration micom is physically independent from a main central processing unit (CPU). The method further includes interpreting a remote control command received from the modem by middleware executed by the guest operation system, and performing, by the multimedia terminal for the vehicle, a control operation according to the remote control command. A multimedia terminal for a vehicle is also disclosed.

Claims

1. A multimedia terminal for a vehicle, comprising:

a modem configured to receive a wakeup command and a remote control command from a remote center outside the multimedia terminal for the vehicle;

an integration micom configured to boot a guest operating system according to the wakeup command received by the modem, the integration micom comprising a middleware executed by the guest operating system; and

a main central processing unit (CPU) configured to be physically independent from the integration micom,

wherein upon receiving the remote control command from the modem, the integration micom is configured to request the middleware to interpret the received remote control command,

wherein after the received remote control command is interpreted by the middleware, the integration micom is configured to control the main CPU to be booted based on a host operating system, and

wherein the multimedia terminal is configured to perform a control operation according to the remote control command.

2. The multimedia terminal according to claim 1, wherein when the remote control command is a command for controlling a vehicle controller, the integration micom is configured to power on the vehicle controller, control the vehicle controller to perform a charging or conditioning operation corresponding to the remote control command, and power off the vehicle controller.

3. The multimedia terminal according to claim 1, wherein when the remote control command is a command for controlling the main CPU, the integration micom is configured to boot the main CPU by the host operating system, control the main CPU to perform a service operation corresponding to the remote control command, and power off the main CPU.

4. The multimedia terminal according to claim 1, wherein power of the main CPU and power of the integration micom are independently controlled.

5. The multimedia terminal according to claim 1, wherein the middleware is configured to interpret resulting data pertaining to a result obtained by performing the control operation to a format of data capable of being transmitted to the modem, transmit the interpreted resulting data to the modem, and power off the main CPU and the integration micom and allow the modem to enter a sleep mode.

6. The multimedia terminal according to claim 1, wherein the guest operating system is configured to share hardware of the multimedia terminal for the vehicle with the host operating system using a hypervisor as a software virtual platform.

7. The multimedia terminal according to claim 1, wherein:

the guest operating system is a real time operating system; and

the main CPU and the integration micom are included in one chip.

14. The multimedia terminal according to claim 1, wherein the modem in sleep mode is configured to transmit the wakeup command received from the remote center to the integration micom.

15. The multimedia terminal according to claim 14, wherein the integration micom is configured to power on the modem after the integration micom boots the guest operating system.

16. The multimedia terminal according to claim 15, wherein after the modem is powered on, the modem is configured to receive the remote control command from the remote center, and transmit the received remote control command to the integration micom.

18. The multimedia terminal according to claim 1, wherein the wakeup command is for requesting the integration micom to be booted to interpret and process the remote control command.

8. A multimedia terminal for a vehicle, comprising:

A vehicle controller configured to transmit a wakeup command and a remote control command;

an integration micom configured to boot a guest operating system according to the wakeup command received from the vehicle controller, the integration micom comprising a middleware executed by the guest operating system; and

a main central processing unit (CPU) configured to be physically independent from the integration micom,

wherein upon receiving the remote control command from the vehicle controller, the integration micom is configured to request the middleware to interpret the received remote control command,

wherein after the received the remote control command is interpreted by the middleware, the integration micom is configured to control the main CPU to be booted based on a host operating system, and

wherein the multimedia terminal is configured to perform a control operation according to the remote control command.

9. The multimedia terminal according to claim 8, wherein when the remote control command is a command for controlling the vehicle controller, the integration micom is configured to control the vehicle controller to perform a charging or conditioning operation corresponding to the remote control command, and power off the vehicle controller.

10. The multimedia terminal according to claim 8, wherein power of the main CPU and power of the integration micom are independently controlled.

11. The multimedia terminal according to claim 8, wherein the middleware is configured to interpret resulting data pertaining to a result obtained by performing the control operation to a format of data capable of being transmitted to the modem, transmit the interpreted resulting data to the modem, and power off the main CPU and the integration micom and allow the modem to enter a sleep mode.

12. The multimedia terminal according to claim 8, wherein the guest operating system is configured to share hardware of the multimedia terminal for the vehicle with the host operating system using a hypervisor as a software virtual platform.

13. The multimedia terminal according to claim 8, wherein:

the guest operating system is a real time operating system; and

the main CPU and the integration micom are included in one chip.

17. The multimedia terminal according to claim 8, wherein when booting the guest operating system is completed, the vehicle controller is configured to transmit the remote control command to the integration micom.
