SYSTEM AND METHOD FOR UNIFIED NETWORK MANAGEMENT IN A VEHICLE}

The present invention relates to an integrated network management system and method in a mobile, and more particularly, to an integrated network management system and method for collectively managing a plurality of networks.

Recently, there are many networks such as CAN, LIN, etc. in a vehicle. Here, since these networks have different configurations and data formats according to the purpose, there was no way to exchange vehicle information between the networks. Therefore, in order to obtain vehicle information transmitted through the networks, the networks had to be connected separately. In addition, since the format of the vehicle information varies depending on the automobile company, the vehicle information may not be efficiently provided to a service provider installed and operated in a vehicle such as a telematics terminal. In addition, since it is impossible to transmit and receive vehicle information between the networks, only a service limited to the vehicle could be provided.

It is an object of the present invention to provide an integrated network management system and method for collectively managing networks such that vehicle information can be freely exchanged between a plurality of networks in a moving object.

Another object of the present invention is to provide an integrated network management system, in particular, a gateway, which can be used universally regardless of the automobile company.

In order to achieve the above object, a gateway for managing a plurality of networks in a mobile according to an embodiment of the present invention includes an integrated interface module for communicating with the networks; And a gateway operation controller connected to the integrated interface module, receiving vehicle information collected by the networks through the integrated interface module, and mapping the transferred vehicle information to a desired format. Here, the gateway operation controller maps the vehicle information to the first format when the gateway is used for the first moving object, and maps the vehicle information to the second format when the gateway is used for the second moving object. .

In the mobile device according to an embodiment of the present invention, the integrated network management system includes a plurality of networks; And a gateway that maps the vehicle information collected through the first network among the networks and provides the second network to the second network. Here, the vehicle information is mapped to the first format when the gateway is used for the first moving object, and the vehicle information is mapped to the second format when the gateway is used for the second moving object.

According to an embodiment of the present invention, a method of managing the network in a mobile having a plurality of networks and at least one service provider may include collecting vehicle information through a first network among the networks; Mapping the collected vehicle information into a desired format; And providing the mapped vehicle information to at least one of a second network and the service provider. The vehicle information is mapped to the first format when the movable body is the first movable body, and the vehicle information is mapped to the second format when the movable body is the second movable body.

An integrated network management system and method in a mobile device according to an embodiment of the present invention uses a gateway to map vehicle information collected by a specific network to a desired format and provide the mapped vehicle information to another network or service provider. That is, the integrated network management system manages the networks collectively, and thus, the networks can be efficiently managed and a vehicle related information service can be provided to a driver. In addition, since the gateway automatically manages the moving object using the vehicle information, internal management of the moving object can be performed stably.

Since the integrated network management system and method in a mobile body according to another embodiment of the present invention can manage networks regardless of the automobile company, the network management system can be used for general purposes. Accordingly, the vehicle application service manufacturer may provide independent services to the vehicle network and the finished vehicle company.

Referring to FIG. 1, the integrated network management system of the present embodiment is a system installed in a moving object (vehicle), and includes a gateway 100 and a plurality of networks, for example, four networks 102, 104, 106, and 108. It includes. Here, the networks 102, 104, 106, or 108 may include a control area network (CAN) for controlling an engine, a local interconnect network (LIN) for controlling a body of the moving body, a multimedia DVD, etc. for controlling a multimedia DVD, and the like. System Transport), FlexRay network method for controlling safety information, etc. may be used. In general, networks 102, 104, 106, and 108 include an electronic control unit (ECU) 110 that is responsible for control functions and a sensor 112 that senses specific devices.

Networks 102, 104, 106 and 108 collect vehicle information of the device they are responsible for, respectively. Here, since the networks 102, 104, 106 and 108 use different ways as mentioned above, the format of the vehicle information collected by the networks 102, 104, 106 and 108 is also different. Therefore, in order to utilize such vehicle information, a format conversion process of the vehicle informations is required, and this conversion process is performed by the gateway 100.

The gateway 100 receives vehicle information collected by the networks 102, 104, 106 and 108 from the networks 102, 104, 106 and 108, and maps the provided vehicle information into a desired format. Let's do it. In addition, the gateway 100 stores the mapped vehicle information and transmits the mapped vehicle information to a service provider such as a specific network or a navigation device to be described later. For example, when the vehicle information collected by the first network 102 is transmitted to the navigation device, the gateway 100 maps the vehicle information transmitted from the first network 102 to a format suitable for the navigation device, Thereafter, the mapped vehicle information is transmitted to the navigation device.

In short, the integrated network management system of the present embodiment exchanges vehicle information between the networks 102, 104, 106 and 108 of the moving object or between the networks 102, 104, 106 and 108 and the specific service provider. Exchange information. In other words, the integrated network management system of this embodiment manages the networks 102, 104, 106 and 108 collectively.

In a conventional mobile body, since the networks used different methods, the exchange of vehicle information between the networks was not possible. However, in the mobile body using the integrated network management system of the present embodiment, since the gateway 100 manages the entire networks, vehicle information transmission and reception between the networks can be freely performed. In addition, even when a new service provider is installed in the moving object, vehicle information exchange can be freely performed between the service provider and the networks as described below.

Hereinafter, the configuration and operation of the gateway 100 serving as a pivotal role in the integrated network management system will be described with reference to the accompanying drawings.

2 is a block diagram illustrating a gateway according to an embodiment of the present invention.

Referring to FIG. 2, the gateway 100 of the present embodiment includes an integrated interface module 200, a gateway operation controller 202, at least one service provider 204, and a storage 206. Here, the service provider 204 may be present in the integrated network management system as a separate element without being included in the gateway 100.

The integrated interface module 200 is a connection path between the networks 102, 104, 106 and 108 and the gateway operation control unit 202, and drivers 210A corresponding to the networks 102, 104, 106 and 108, respectively. , 210B, 210C, and 210D) and interfaces 212A, 212B, 212C, and 212D.

According to one embodiment of the invention, the integrated interface module 200 sets priorities according to the importance of the vehicle information transmitted from the networks 102, 104, 106 and 108, and the networks 102, 104, When a plurality of pieces of vehicle information are transmitted from 106 and 108, the vehicle information is transmitted to the gateway operation controller 202 according to the priority. For example, if the networks 102, 104, 106, and 108 use the CAN, LIN, MOST, and FlexRay schemes, the vehicle information transmitted from the first and fourth networks 102 and 108 may be stored in the second and the second, respectively. 3 Prioritize transmission over vehicle information transmitted from networks 104 and 106.

The gateway operation control unit 202 includes an operating system unit 214 and middleware 216 as a part of controlling overall operation of the gateway 100.

The operating system unit 214 is a part where operating software such as QNX, VxWorks, WinCE, Linux, etc. is installed, and the vehicle information or service program transmitted from the networks 102, 104, 106, and 108 through the integrated interface module 200. The vehicle information transmitted from the provider 204 is processed in real time.

The middleware 216 parses and maps vehicle information transmitted from the networks 102, 104, 106, and 108 or vehicle information transmitted from the service provider 204 to a desired format, and maps the mapped vehicle information. To the network 102, 104, 106, and 108 or the service provider 204. In addition, the middleware 216 stores the mapped vehicle information in the storage unit 206, or reads out the vehicle information stored in the storage unit 206 so that the network 102, 104, 106, 108 or service provider ( 204).

According to another embodiment of the present invention, the middleware 216 or the gateway operation controller 202 may include a separate storage means other than the storage 206.

The service provider 204 is a part for providing an application service to a driver, and includes a navigation device, a high pass device, a DVD device, and the like.

Hereinafter, the operation of the integrated network management system of the present embodiment, that is, the integrated network management method will be described with reference to the accompanying drawings.

3 is a flowchart illustrating a unified network management method according to an embodiment of the present invention.

Referring to FIG. 3, the service provider 204 requests vehicle information of a specific network from the gateway operation controller 202 (S300). For example, if the driver wants to know the room temperature, the driver may request information about the room temperature through the service provider 204.

Subsequently, the gateway operation controller 202 requests vehicle information to the corresponding network through the integrated interface module 200 according to the request, and the network collects the requested vehicle information (S302).

Subsequently, the vehicle information collected by the network is transmitted to the gateway operation control unit 202 through the integrated interface module 200, and the gateway operation control unit 202 is configured to provide the vehicle information in a format suitable for the service provider 204. To map (S304).

Thereafter, the gateway operation control unit 202 provides the mapped vehicle information to the service provider 204 (S306), and the service provider 204 displays the provided vehicle information to the driver. As a result, the driver can obtain the desired information, for example information about the room temperature.

Referring to FIG. 4, vehicle information is input from the specific network to the gateway operation controller 202 through the integrated interface module 200 (S400).

Subsequently, the gateway operation controller 202 maps the input vehicle information into a desired format (S402). For example, when the vehicle information provided from the network has a format as shown in FIG. 5A, but the service provider 204 satisfies only the format as shown in FIG. 5B, the gateway operation control unit 202 Converts and maps vehicle information as shown in FIG. 5A into a format as shown in FIG. 5B.

Subsequently, the gateway operation control unit 202 stores the mapped vehicle information in the storage unit 206 (S404).

Then, it is determined whether or not transmission of vehicle information is requested from the service provider 204 (S406).

When the transmission of the vehicle information is requested, it is determined whether the requested vehicle information is stored in the storage unit 206 (S408).

When the requested vehicle information is stored in the storage unit 206, the gateway operation controller 202 reads the vehicle information from the storage unit 206 (S410).

Subsequently, the gateway operation control unit 202 provides the read vehicle information to the service provider 204 (S412).

On the other hand, if the requested vehicle information is not stored in the storage unit 206, the network management method is terminated or a notification message notifying the driver that the requested vehicle information does not exist through the service provider 204. Provide the driver.

In the above, the mapping process is described based on one moving object, but may also be described based on a plurality of moving objects. For example, vehicle information as shown in FIG. 5A is used for the first mobile body produced by the first automobile company, and in FIG. 5B in the second mobile body produced by the second automobile company. Assume that vehicle information as is used. In this case, if the gateway operation control unit 202 can map both vehicle information formats, one gateway 100 may be used for both moving objects. In detail, when the gateway 100 is used for the first moving object, the gateway operation control unit 202 maps vehicle information transmitted from a specific network to the format shown in FIG. 5A, and the gateway 100. Is used for the second mobile unit, vehicle information transmitted from a specific network can be mapped to the format shown in FIG. That is, the gateway 100 of the present embodiment can be used as a general purpose gateway regardless of the automobile company.

6 is a flowchart illustrating a unified network management method according to another embodiment of the present invention.

Referring to FIG. 6, a new service provider is installed in the mobile body (S600).

Next, an operating program for operating the service provider is installed (S602).

Subsequently, information about the service provider, for example, information format, is stored in the storage unit 206 (S604).

Then, vehicle information is exchanged between networks and the service provider (S606). Of course, even in this case, the gateway operation controller 202 maps the vehicle information and transmits the vehicle information mapped to the desired device. Also, although not mentioned, the operations of the network management system described above may be performed between the networks and the service provider.

7 is a flowchart illustrating a unified network management method according to another embodiment of the present invention.

Referring to FIG. 7, a specific network detects an internal state of a vehicle and transmits vehicle information having a detection result to the gateway operation controller 202 through the integrated interface module 200 (S700).

Subsequently, the gateway operation control unit 202 analyzes the transmitted vehicle information to determine whether there is an abnormality in the moving object (S702). For example, it is determined whether or not a failure may occur in the engine due to a high internal temperature of the moving body.

If it is determined that there is an abnormality in the moving object, the gateway operation control unit 202 transmits specific information to the corresponding network to control the network to take appropriate measures (S704). For example, when it is determined that the internal temperature of the moving object is too high, the gateway operation control unit 202 controls the network so that the window of the moving object can be opened. However, this control process may be performed at the driver's request, but may be automatically performed by the integrated network management system. As another example, when the driver is not recognized but detects that there is a child, etc., the integrated network management system may automatically activate the brake.

8 is a block diagram illustrating an integrated network management system according to another embodiment of the present invention.

Referring to FIG. 8, the integrated network management system of the present embodiment includes a gateway 800, a plurality of networks, for example, three networks 802, 804, and 806, and an external communication module 808.

Since the remaining components except for the external communication module 808 are the same as those of the integrated network management system of FIG. 1, detailed descriptions of the same components will be omitted.

The external communication module 808 is a module for connecting the components of the mobile unit and an external device (not shown) existing outside of the mobile unit, for example, CDMA, GSM, DSRC, wireless LAN, WAVE, GPS system, etc. use. As a result, the gateway 800 of the mobile device can communicate with the external device through the external communication module 808.

Hereinafter, the operation of the gateway 800 in a state in which the gateway 800 and the external device are connected through the external communication module 808 will be described with reference to the accompanying drawings.

Thereafter, the gateway 800 transmits the mapped vehicle information to the external device through the external communication module 808 (S906). In this case, the transmission of the vehicle information may be repeatedly performed periodically or only at the request of the external device.

Subsequently, the external device analyzes vehicle information transmitted from the gateway 800 (S908), and transmits response information according to the analysis result to the gateway 800 (S910). For example, when it is determined that it is time to replace the engine oil of the moving object as a result of the analysis, the external device transmits response information indicating that the engine oil is to be replaced to the gateway 800.

Subsequently, the gateway 800 provides the response information to the driver through the service provider or generates specific vehicle information according to the response information and transmits the specific vehicle information to the corresponding network (S912). For example, when the external device transmits response information indicating that the engine oil needs to be replaced, the gateway 800 notifies the driver through the service provider. Thus, the driver can know when to replace the engine oil even without visiting a car repair shop. As another example, when the external device transmits response information indicating that the window is desired to be opened because the internal temperature of the moving body is too high, the gateway 800 transmits specific vehicle information to the corresponding network according to the response information to automate the window. You can open it with

Although not mentioned above, when a new service provider is installed, the gateway 800 may download and use a program for operating the service provider from the external device through the external communication module 808.
