Description

In-vehicle device and network communication hub providing method with network communication hub function {APPARATUS HAVING FUNCTION OF NETWORK COMMUNICATION HUB IN VEHICLE AND METHOD THEREOF}

The present invention relates to an in-vehicle device having a network communication hub function and a method for providing a network communication hub. In particular, the present invention relates to a predetermined device used in a vehicle so as to communicate by applying a profile specialized in in-vehicle data transmission and function control. The present invention relates to a method for providing an in-vehicle device and a network communication hub having a network communication hub function for facilitating communication between devices and between devices and an external infrastructure.

Conventionally, in order to display or control information on a function of a vehicle output from another device on a predetermined in-vehicle device, function information or a control signal is communicated between devices in a connected vehicle using a wire or the like.

However, as the necessity for communication between devices in the vehicle increases, the weight of the vehicle increases due to the increase in the number of wires, the problem of wire path design, and the problem of failure diagnosis.

In recent years, high-end vehicles are equipped with radio monitors, CDs, DVDs, navigation devices, LCD monitors in the front, rear, and rear seats, and many multimedia devices such as Internet access, traffic information processing, and accident transmission are installed in the telematics field.

In the communication of such a multimedia device, in order to improve communication problems using the wire, a method of exchanging information with each other by connecting in-vehicle multimedia devices to a network is used.

However, the information exchange method using the network also causes the same phenomenon as the wire design problem caused by the increase of the in-vehicle devices as the variety of multimedia devices gradually increases.

That is, since the manufacturers of the multimedia devices are different from each other, the compatibility between the devices in the vehicle system is extremely insufficient, and therefore, various communication and function control methods must be accommodated for communication between the devices.

Conventional in-vehicle communication method communicates with in-vehicle devices such as car PCs to display meaningful information to the user or remotely control information of devices in a certain area range, such as home automation There was also a communication method that can use device information usefully.

However, this is also a one-to-one communication method such as a master and a client, and due to the configuration in which data is processed and converted through one master server, it is limited and exclusive in a structure in which various manufacturers and companies are currently struggling. In addition, it is difficult to maintain such as adding devices in the vehicle and improving service, and the scalability is very limited.
