Further, the framework 100 may generate and transmit a command based on service data definition information interpreted by the company A application 510 using the service ID.

For example, it is assumed that the service ID includes information such as 10, 2, and 1. In this case, the company A application 510 may search a service data definition table using the service ID received from the framework 100 and obtain service data definition information corresponding to the service ID. That is, company A application 510, based on the service data definition table, the first information (10) included in the service ID is to start the car for 10 minutes, and the second information (2) included in the service ID is to set the air conditioning temperature to 2 degrees. Controlling, third information (1) included in the service ID is determined to be performing air conditioning control, and service data definition information (starting the engine for 10 minutes, controlling the air conditioning temperature to 2 degrees, performing air conditioning control) You can return to the framework (100).

That is, the service ID transmitted from the company A server 810 is information uniquely used by the company A server 810, and the framework 100 may not be able to recognize its meaning. In this case, the company A application 510 may interpret the service ID so that the framework 100 can recognize it, and provide the service ID to the service manager 110 of the framework 100 .

Meanwhile, when information is required, the framework 100 may call the company A application 510 to receive the information, and a service ID may be used to call the application.

6 illustrates a method of performing another operation by a framework based on status information reported from a vehicle as an example of a vehicle interworking service.

The specific device 411 may transmit state data including its state command to the framework 100 . In this case, the device manager 140 of the framework 100 may receive state data and transmit a state command to the command manager 130 .

Meanwhile, the command manager 130 may separate the header and body from the command and transmit body information (eg, 0x01) to the service manager 110 .

In this case, the service manager 110 may transmit body information (eg, 0x01) to the company A application 510 . In this case, the company A application 510 may determine that 0x01 is an airbag explosion, and transmit service data definition information including airbag explosion to the service manager 110 .

Meanwhile, depending on the type of status information, there may be a process that performs an additional operation in the vehicle without being directly reported to the server. For example, there may be a process that displays a notification on a device (eg navigation) when an airbag is deployed.

In this case, the action manager 120 of the framework 100 may receive service operation procedure definition information corresponding to the service data definition information from the company A application 510 . For example, the service operation procedure definition information may include a notification display operation.

In this case, the command manager 130 may receive command definition information of an operation to be performed (notification display operation) and generate a command based on the received command definition information.

In this case, the device manager 140 may receive vehicle communication method definition information of the second device 412 to which the command is to be transmitted, and transmit a command to the second device 412 based on the received vehicle communication method definition information. .

In this case, the second device 412 (for example, a navigation device) may display a notification such as “an accident has occurred” on the screen. Also, the second device 412 may transmit a response to the command to the device manager 140 .

As such, the present invention constitutes a common framework that can be applied to various manufacturers. That is, since the application interprets data and provides necessary information to the connection control device 10, even if the server or application is changed to that of another manufacturer, the operation of the framework is the same. Accordingly, the manufacturer of the connection control device 10 can sell the same product to various vehicle manufacturers without having to design and manufacture the connection control device 10 targeting a specific manufacturer. Accordingly, there is an advantage in that development costs can be saved and stability of the connection system can be secured.

In addition, from the viewpoint of a vehicle manufacturer, a stable vehicle-linked service can be implemented by simply adding a service table to an application mounted on a vehicle. In addition, when adding/changing/deleting a service and adding/changing/deleting an in-vehicle device, there is an advantage in that only a simple process of changing the service table is performed without the need to redesign the entire system.

In addition, according to the present invention, by configuring the connection control device 10 independently of the vehicle and the application installed in the vehicle, the operation is simplified, the service response time is minimized, and stability is secured in response to errors in other systems. there is

The above-described present invention can be implemented as computer readable code on a medium on which a program is recorded. The computer-readable medium includes all types of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include Hard Disk Drive (HDD), Solid State Disk (SSD), Silicon Disk Drive (SDD), ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. there is Also, the computer may include a control unit. Accordingly, the above detailed description should not be construed as limiting in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
