Compare the authentication information stored in the authentication process. If the terminal authentication is successful, the data packet formed by the data packet forming unit 114 may be wirelessly transmitted to the smart terminal 500 using the wireless communication unit 116 under the control of the wireless vehicle management terminal 110.
When there is a user request for remote starting of the vehicle and locking and unlocking of the door through the wireless communication unit 116, the management terminal control unit 110 transmits to the telematics device 103 through the OBD interface 103, and transmits the telematics device ( 103 performs a given processing operation according to the received user command.
Referring to FIG. 3, the smart terminal 500 may include a smart terminal controller 505 that controls overall operations of the terminal, and a touch screen 501 that may receive a user command through a touch and display data on a screen. Include. To this end, the touch screen 501 includes a touch sensor 502 and a display unit 503.
The wireless communication unit 513 communicates with the wireless vehicle management terminal 107.
The vehicle database 507 builds a database of vehicle-specific specification information as a service object, and may include, for example, a vehicle manufacturer, a vehicle model, an exhaust amount, and the like.
The collection data processing unit 508 calculates a vehicle state diagnosis, a consumable replacement cycle, a vehicle diagnostic unit 509 for processing vehicle operation and location information, and calculates a consumable replacement cycle for the collected data received from the wireless vehicle management terminal 107. The unit 510 includes a driving and location information processing unit 511. In this case, the vehicle diagnosis unit 509, the consumable replacement cycle calculation unit 510, and the operation and location information processing unit 511 may perform a vehicle diagnosis based on the vehicle specification information set by the user among the specification information provided by the vehicle database 507. It processes exchange cycle calculation and operation and location information.
The image reproducing unit 512 decompresses the recorded image received from the wireless vehicle management terminal 107 and reproduces the decompressed image data for display on the touch screen 501.
Meanwhile, the smart terminal controller 505 wirelessly transmits a user command to the wireless vehicle management terminal 107 through the wireless communication unit 513 when receiving a request for remote starting and locking and unlocking the door from the user. Then, the management terminal control unit 110 transmits to the telematics device 103 through the OBD interface 103, and performs the given processing operation according to the user command received by the telematics device 103.
The operation of the vehicle status checking and control system using the smart terminal according to the embodiment of the present invention configured as described above will be described in detail.
The wireless vehicle management terminal 107 is connected to the diagnostic terminal 106 provided in the vehicle. At this time, if it is difficult to directly connect the wireless vehicle management terminal 107 can be connected to each other using an adapter.
The user makes an authentication request using the terminal serial number assigned to the wireless vehicle management terminal 107 using the smart terminal 500 (602).
If the terminal authentication is successful (Yes of 604), the vehicle management application is downloaded (606). At this time, a database of the specification information for each vehicle type is built in the vehicle database 507, and an icon for the vehicle management application is formed on the touch screen 501. The user who selects this icon is in an activated state that can receive all the services of the present system.
In the activated state, the user sets and registers the specifications and function options of the target vehicle through the touch screen 501, and this setting operation is continuously maintained after the initial setting. Thereafter, the user opens the authentication window of the touch screen 501 and requests user authentication using the ID and password given when registering a member in the authentication window (108).
If the user authentication is successful (Yes of 110), the user requests a connection to the wireless vehicle management terminal 107 by using the smart terminal 500, and if the connection is made to request the transmission of the collected data (612). At this time, the smart terminal 500 transmits a terminal serial number for terminal authentication input by the user.
The wireless vehicle management terminal 107 compares the terminal authentication number received through the wireless communication unit 116 with the authentication information stored in the terminal authentication information storage unit 115 and if they match with each other, the data formed by the data packet forming unit 114. The packet is transmitted to the smart terminal 500. Then, the smart terminal 500 touches a series of processing results for the vehicle diagnosis, consumable replacement cycle, driving, and location information processed by the collection data processing unit 508 according to a user command by a touch operation of the touch screen 501. Displayed at 501. At this time, if a user requests a playback of a video recorded around the vehicle, the video playback unit 512 decompresses and plays the recorded video on the touch screen 501. On the other hand, when a user receives a request for remote start and lock and unlock of the door, the user command is wirelessly transmitted to the wireless vehicle management terminal 107 through the wireless communication unit 513. Then, the management terminal control unit 110 transmits to the telematics device 103 through the OBD interface 103, and performs the given processing operation according to the user command received from the telematics device 103 (614).
Next, with reference to Figure 4, a vehicle operation state monitoring method in a smart key system according to an embodiment of the present invention. As shown in FIG. 4, the user (driver) selects the vehicle information menu in the application program of the mobile communication terminal (S401). Next, the vehicle control unit of the vehicle acquires data on the vehicle operation state from the OBD-II connector or the like (S402), and transmits the vehicle operation state data to the mobile communication terminal via the smart key (S403). When the mobile communication terminal receives the vehicle operation state data (S404), the mobile communication terminal displays the data on a display device or the like (S405).
It is intended that the present invention not be limited by the above-described embodiments and the accompanying drawings, but only by the appended claims. Accordingly, various forms of substitution, modification, and alteration may be made by those skilled in the art without departing from the scope of the claims and the technical spirit of the present invention, which is also within the scope of the present invention.
