Hereinafter, a method of diagnosing a vehicle at a remote location according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

First, the telematics subscriber should subscribe to the remote vehicle diagnostic service in the service provider 50. According to the first embodiment of the present invention, the service providing center 50 should have received a unique authentication password from the vehicle diagnosis service subscription information and the subscriber. The unique authentication password may be a numeric password when the communication terminal 70 is a landline telephone 73, and numbers or letters in the case of the PC 71 and the PDA 72 and the mobile phone 74. It can be an ID and a password. In the case of a landline telephone, the service providing center 50 uses the ARS system, and it is preferable to enhance security by requesting additional authentication information such as a social security number by the ARS.

First, the communication terminal 70 accesses the service providing center 50 in step 301 when a service providing center connection command is input by the subscriber. The connection command is the telephone number of the service providing center 50 when the communication terminal 70 is a wired telephone 73, and the service request command when the communication terminal 70 is connected to the service providing center 50 homepage. And so on.

When connected to the service providing center 50, the service providing center 50 transmits a service selection request message for the services being provided in step 303. The service selection request message may be a graphic or text and voice signal according to the form of the communication terminal 70.

Upon receiving the service selection request signal, the communication terminal 70 checks whether a remote diagnosis service is selected by a user among a plurality of services, and if the remote diagnosis service is selected, service the remote diagnosis service request message in step 305. The transmission center 50 transmits the data through the network.

In step 307, the service providing center 50 transmits an authentication request message to the communication terminal 70 to determine whether the subscriber using the communication terminal 70 that has transmitted the remote diagnosis service request message is a registered subscriber. . The communication terminal 70 receiving the authentication request message receives an authentication password from the subscriber and transmits the authentication password to the service providing center 50 in step 309.

The service providing center 50 receives the authentication password and compares the authentication password stored in advance for the subscriber with the received authentication password to determine whether the service is the same. In order to perform a control service, the telematics terminal 10 is connected to the subscriber. At this time, the access request is made by the service providing center 50, and the service providing server 50 includes a unique number indicating that the service providing server 50 is itself.

The telematics terminal 10 is connected to form a data communication path when a call having a unique number and its own number of the service providing center 50 is received.

When the telematics terminal 10 is connected, the service providing center 50 transmits a remote diagnosis request message to the telematics terminal 10 requesting a remote diagnosis in step 313.

However, in order to use the SMS service, the service providing center 50 transmits the remote diagnosis request message of step 313 to the telematics terminal 10 in the SMS short message without performing step 311. Typically, the SMS short message includes a calling party (service providing center 50) phone number and a called party (telematics terminal 10).

Then, the telematics terminal 10 diagnoses the vehicle state through the vehicle diagnosis unit 14 and the location information processor 18, etc. in step 315, receives the vehicle diagnosis information, generates a vehicle diagnosis information message, and generates a data communication path in step 315. Alternatively, the SMS short message is transmitted to the service providing center 50.

The service providing center 50 receiving the vehicle diagnostic information message changes to a vehicle diagnostic information message according to the communication terminal 70 requesting the remote vehicle diagnostic service in step 317, and transmits it to the communication terminal 70. For example, when the communication terminal 70 is a landline telephone 73, text data is converted into voice and transmitted. In the case of a PC 71 or a PDA 72 or a mobile phone 74, text or graphics are transmitted. Convert and send.

The communication terminal 70 receiving the vehicle diagnostic information message informs the subscriber by voice and / or text and / or graphic about the vehicle diagnostic information.

The service providing center 50 transmits a vehicle control check message to the communication terminal 70 asking whether to perform vehicle control according to the vehicle diagnosis in step 319 after the vehicle diagnosis information message is transmitted.

The communication terminal 70 then informs the subscriber by receiving the vehicle control check message. At this time, the subscriber checks or listens to the vehicle status visually and if there is an error, the subscriber will input a vehicle control request command for controlling the vehicle through the communication terminal 70.

In step 321, the communication terminal 70 generates a vehicle control request message and transmits the generated vehicle control request message to the service providing center 50.

In step 407, when the service providing center 50 is connected to the telematics terminal 10, the service providing center 50 transmits a remote diagnosis request message to the telematics terminal 10 in step 409. Upon receiving the remote diagnosis request message, the telematics terminal 10 transmits an authentication request message to the service providing center 50 in step 411.

In step 413, the service providing center 50 receiving the authentication request message converts the authentication request message into an authentication request message according to the type of the communication terminal 70 and transmits the authentication request message to the communication terminal 70. When the communication terminal 70 receiving the authentication request message transmits the authentication password to the service providing center 50 in response to the authentication request message in step 415, the service providing center 50 transmits the telematics terminal 10 in step 417. In this case, an authentication identifier transmission message having the authentication password is generated and transmitted.

The telematics terminal 10 receiving the authentication identifier transmission message collects vehicle diagnosis information, generates a vehicle diagnosis information message, and transmits the generated vehicle diagnosis information message to the service providing center 50 in step 419. In step 421, the service providing center 50 converts the vehicle diagnosis information message according to the type of the communication terminal 70 into the vehicle diagnostic information message and transmits the message to the communication terminal 70.

When the vehicle diagnostic information is input to the communication terminal 70 as described above, the vehicle is controlled by performing steps 423 to 435. Steps 423 to 435 respectively control the vehicle from a remote location by sequentially performing operations corresponding to steps 331 to 319 of FIG. 3. It should be noted that the steps of FIG. 3 and FIG. 4 omit the description by performing the same operation.

In the above, the wired telephone 73 provides the vehicle diagnostic information using the ARS, and in the case of the mobile phone 74, the PC 71, or the PDA 72, text or graphics by data communication using an ARS or a mobile communication network. It provides vehicle diagnostic information. In the above description, in the case of providing the voice, the case where the ARS system is applied has been described, but a counselor may be performed instead of the ARS.

In addition, although the communication terminal 70 performs the vehicle control at a remote location after receiving the vehicle diagnostic information, the subscriber may perform the vehicle control without checking the vehicle diagnostic information.

5 is a flowchart illustrating a vehicle control method according to a third embodiment of the present invention.

3 and 4, the vehicle control target and control requirements are received from the service providing center 50 and selected. However, in FIG. 5, when the communication terminal 70 selects a vehicle control object and a control request to control from among the vehicle control object and the control requirements, the vehicle control information message is generated in step 521. It is to send a message to the service provider (50).

In step 525, the service providing center 50 regenerates the vehicle control information message according to the telematics protocol, that is, the TTP_T or TTP_S data format, and transmits the message to the telematics terminal 10.

The telematics terminal 10 receives the vehicle control information message and transmits the vehicle control result to the communication terminal 70 by performing the same process as the above-described steps 329 and 331 of FIG. 3 and 433 and 435 of FIG. 4. .

For this purpose, the communication terminal 70 may be applied to a computer 71 or a PDA 72 and a mobile phone 74.

According to the present invention as described above, since the vehicle owner can perform the diagnosis of the vehicle at a remote location, the vehicle owner can check the current state of the vehicle at any place and control the vehicle at a remote location. It has the advantage that the owner can park with confidence even if the owner moves away from the vehicle.
