Abstract

A car control system is disclosed. The car control system for controlling a car by being linked with a car control device (electronic control unit, ECU) that is installed inside the car for electronic control of the car can include: an authentication server configured to perform access authentication for a user terminal and configured to generate an authentication result based on least one of terminal information of the user terminal and vehicle identification information; and a car access device configured to be directly connected with the car control device through an internal network of the car and configured to determine whether a car control request for control of the car by the user terminal is to be relayed to the car control device according to the authentication result of the user terminal.

First claim

What is claimed is:

1 . A method of controlling a car, the method comprising:
authenticating a mobile terminal using information from the mobile terminal and by performing wireless communication with a remote server via an access device; and controlling the car by the mobile terminal if the mobile terminal is authenticated, wherein, in response to a result of the authenticating being an authentication failure, the access device is configured to change a car control state to an abnormal operation mode, control the car, and notify the car control state to a car control device.

2 . The method of claim 1 , wherein the mobile terminal controls the car by having requests of the mobile terminal relayed by the access device to the car control device.

3 . The method of claim 1 , wherein if the car control state is set to the abnormal operation mode, the car is controlled to be operated by at least one of turning on emergency blinkers and registering an emergency key.

4 . The car control system of claim 1 , wherein, if the car control state is changed to the abnormal operation mode, the car access device is configured to delete registered authentication information for the user terminal and block connection pursuant to an access request for control of the car by the user terminal.

5 . A car access device for controlling a car comprising:
a first communication unit which communicates with a mobile user terminal; a second communication unit which is non-portably installed in the car and which communicates with a car control device that controls a plurality of functions executed in the car; a third communication unit which communicates with an authentication server to authenticate the mobile user terminal requesting control of the car; and a controller which controls the first communication unit, the second communication unit, and the third communication unit, wherein if communication with the authentication server is not available, the car access device is configured to: generate an emergency authentication result by checking whether the user terminal is a registered emergency terminal, perform the emergency authentication without linking to the authentication server, and set a car control state to an emergency mode based on the emergency authentication result, wherein the car access device is configured to obtain the terminal information from the user terminal and is configured to perform the emergency authentication by checking whether the terminal information is included in pre-registered emergency terminal information.

6 . The car access device for controlling a car of claim 5 , wherein if communication with the authentication server is available, user information received by the first communication unit is relayed to the third communication unit for transmission to the authentication server,
wherein the third communication unit receives from the authentication server results of an authentication based on the user information, wherein if the results of the authentication indicate that the mobile user terminal is authorized, the second communication unit relays requests for controlling the car from the mobile user terminal to the car control device.

7 . The car control system of claim 5 , wherein a limited car control request of the user terminal is relayed to the car control device in the emergency mode.

8 . The car control system of claim 7 , wherein the limited car control request is a car ignition control.

9 . A car access device for controlling a car comprising:
a first communication unit which communicates with a car control device that controls a plurality of functions executed in the car; a second communication unit which communicates with an authentication server to authenticate the mobile user terminal requesting control of the car; and a controller which controls the first communication unit, and the second communication unit, wherein, if stolen car information is received from the authentication, the car access device is configured to change a car control state to a stolen mode according to the stolen car information and transmit the car control state to the car control device, wherein, while the car control state is set to the stolen mode, the car access device is configured to obtain position information of the car access device at regular intervals and to transmit the obtained position information to the authentication server.
