Abstract

An in-vehicle infotainment device includes a first processor for executing a web application, and a second processor for outputting vehicle data to the first processor. The first processor includes a first-processor-side inter-node communication (INC) interface module for transmitting and receiving information to and from the second processor, the second processor includes a second-processor-side INC interface module for transmitting and receiving information to and from the first processor, and the first processor provides the vehicle data received from the second processor to the web application if a request for vehicle data is received from the web application.

Claims

1. An in-vehicle infotainment device configured to be installed in a vehicle and comprising:

a first processor configured to execute a web application; and

a second processor configured to output vehicle data to the first processor, the second processor including a controller area network (CAN) controller for generating a first CAN message including the vehicle data,

wherein the first processor includes a first-processor-side inter-node communication (INC) interface module configured to communicate with the second processor,

wherein the second processor includes a second-processor-side INC interface module configured to communicate with the first processor,

wherein the first processor is configured to;

provide the vehicle data output from the second processor to the web application in response to a request for vehicle data that is received by the first processor from the web application,

display the web application on a display unit of the in-vehicle infotainment device,

receive the vehicle data output from the second processor via the first-processor-side ICN interface module,

receive, via the web application, a vehicle control command,

convert the vehicle control command to a second CAN message, and

output the second CAN message to the second processor such that the second processor performs a specific vehicle function,

wherein the second processor is configured to output the second CAN message to the CAN controller.

2. The in-vehicle infotainment device according to claim 1, wherein the first processor is configured to control a change of an execution screen of the displayed web application according to the vehicle data output from the second processor.

3. The in-vehicle infotainment device according to claim 1, wherein the first processor is configured to receive a user action through an execution screen of the displayed web application and output a vehicle control command according to the user action.

4. The in-vehicle infotainment device according to claim 3, wherein the first processor is configured to restrictively receive the user action according to the vehicle data output from the second processor.

5. The in-vehicle infotainment device according to claim 3, wherein, the first processor is configured to restrictively output the vehicle control command according to a specific vehicle status.

6. The in-vehicle infotainment device according to claim 1, wherein, in response to a vehicle control command received from the web application, the first processor is configured to output the vehicle control command to the second processor via the first-processor-side INC interface module.

7. The in-vehicle infotainment device according to claim 1, wherein the first processor is configured to provide the web application with the vehicle data output from the second processor in an interface definition language (IDL) via a web vehicle plug-in.

8. The in-vehicle infotainment device according to claim 1, wherein the vehicle data is formatted in a controller area network (CAN) communication language.

9. The in-vehicle infotainment device according to claim 1, wherein the web application is written in Java Script or HyperText Markup Language (HTML) code.

10. A data processing method performed by an in-vehicle infotainment device, the method comprising:

generating, by a controller area network (CAN) controller of a second processor, a first CAN message, the first CAN message including vehicle data;

receiving, by a first processor, the vehicle data from the second processor, wherein data transmission and reception between the first and second processor is performed according to an inter-node communication protocol;

receiving, by the in-vehicle infotainment device installed in a vehicle, a request for vehicle data from a web application;

displaying an execution screen of the web application on a display unit of the in-vehicle infotainment device;

receiving, by the first processor, the vehicle data from the second processor;

providing, by the first processor, the received vehicle data to the web application;

receiving, by the in-vehicle infotainment device, a vehicle control command from the web application;

converting, by the first processor, the vehicle control command to a second CAN message; and

outputting, by the first processor, the second CAN message to the second processor such that the second processor controls the vehicle.

11. The data processing method according to claim 10, further comprising:

changing the execution screen of the displayed web application according to the received vehicle data.

12. The data processing method according to claim 10, wherein the vehicle control command includes a user action received via the web application.

13. The data processing method according to claim 12, further comprising:

determining whether a current vehicle status is a specific status based on the received vehicle data; and

changing and displaying an execution screen of the web application for receiving a user action to correspond to the specific status when the current vehicle status is the specific status.

14. The data processing method according to claim 13, wherein the vehicle control command is restrictively output when the vehicle status is the specific status.

15. The data processing method according to claim 13, wherein the user action is restrictively received according to the received vehicle data.

16. The data processing method according to claim 10, wherein the vehicle data is provided to the web application in an interface definition language (IDL) via a web vehicle plug-in.

17. The data processing method according to claim 10, wherein the web, application is written in Java Script or HyperText Markup Language (HTML) code.
