The output unit 130 may include a display for displaying an operation state of the self-diagnosis and control apparatus 100 of the vehicle, a self-diagnosis result, and the like, and may include a speaker for guiding the display to a voice. Here, the display may be used as an input device in addition to an output device when a sensor for sensing a touch operation is provided. That is, when a touch sensor such as a touch film, a touch sheet, or a touch pad is provided on the display, the display operates as a touch screen, and the input unit 120 and the output unit 130 may be integrated.

The display may be a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, , A field emission display (FED), and a 3D display (3D display).

Also, the output unit 130 may include a dashboard provided in the vehicle.

The communication unit 140 may include a communication module that supports communication interfaces with electrical components and / or control units provided in the vehicle.

As an example, the communication module may be communicatively connected to a fuse switch, an instrument panel, a display, a dashboard, and the like provided in the vehicle. At this time, the communication module can receive the ON signal of the fuse switch. In addition, the communication module can transmit the operation status and diagnostic result of the self-diagnosis control apparatus 100 to an instrument panel, a display, an instrument panel, and the like. Also, the communication module may be connected to a cluster (CLU) and a plurality of control units provided in the vehicle, and may transmit and receive a signal for self-diagnosis when the fuse switch is on.

Here, the communication module can support vehicle network communication such as CAN (Controller Area Network) communication, LIN (Local Interconnect Network) communication, and Flex-Ray communication.

The storage unit 150 may store data and programs necessary for the self-diagnosis and control apparatus 100 to operate. At this time, the storage unit 150 may store a set value for operation of the self-diagnosis controller 100 of the vehicle, for example, a condition value for determining an abnormality from the self-diagnosis result. In addition, the storage unit 150 may store algorithms for performing self-diagnosis and commands for controlling operations of the clusters and the respective control units for self-diagnosis.

Clusters and control units provided in the vehicle are shipped in a factory-initialized state, in which the fuse switch is turned OFF.

When the vehicle is delivered to the vehicle purchaser, the vehicle leader turns on the fuse switch of the vehicle, at which time the fuse switch sends an ON signal to the vehicle's self-diagnosis control apparatus 100.

The mode determination unit 160 determines whether the mode of the vehicle is changed. When the ON signal of the fuse switch is received through the communication unit 140, the mode determination unit 160 recognizes that the mode of the vehicle is changed from the ON signal of the fuse switch received through the communication unit 140 . For example, the mode determination unit 160 may recognize that the mode of the vehicle according to the state of the fuse switch is changed from the before mode to the after mode.

If the mode determiner 160 determines that the mode of the vehicle has been changed to the after mode, the controller 110 performs a self-diagnosis operation on each control unit of the vehicle. For example, each control unit of the vehicle can be a body control module (BCM), an engine control module (ECM), a transmission control module (TCM), a powertrain control module (PCM), a brake control module (EBCM) ) And a Power Steering Control Module (PSCM). Of course, it is a matter of course that each control unit of the vehicle can be any unit that controls the operation of the vehicle.

At this time, the control unit 110 requests the message generating unit 170 to generate a notification message for the mode conversion information of the vehicle.

In response to a request from the control unit 110, the message generating unit 170 generates a notification message including the vehicle mode conversion information of the after-mode in the after-mode, Lt; / RTI >

The control unit 110 may transmit the notification message generated by the message generation unit 170 to the clusters and the control units provided in the vehicle. Here, the clusters and the respective control units provided in the vehicle can receive the notification message via the vehicle network, for example, CAN connected to the communication unit 140, and can force the load by the received notification message . At this time, the cluster and each control unit can confirm whether or not an error code, for example, a DTC (Diagnostic Trouble Code) is generated.

The controller 110 requests the message generator 170 to generate a drive completion confirmation message and transmits the drive completion confirmation message generated by the message generator 170 to the clusters and the control units.

When a response message corresponding to the drive completion confirmation message is received from the cluster and each control unit, the control unit 110 transmits a request message requesting error code information from the driven cluster and each control unit to the message generation unit 170 ), And transmits the generated request message to the cluster and each control unit. At this time, the control unit 110 sequentially transmits a request message to the cluster and each control unit according to a predetermined order.

When a response message is received from the cluster and each control unit in response to the request message, the state checking unit 180 identifies the control unit in which the error code is generated based on the information included in the received response message.

If there is no control unit in which an error code has been generated, the control unit 110 causes the cluster to display information indicating that the control unit is in a normal state as a result of self diagnosis.

On the other hand, if there is a control unit in which an error code is generated, the control unit 110 transmits information indicating the occurrence of an error code, for example, a DTC code value, do.

Thereby, the vehicle consignee and / or the user can easily confirm the state of each control unit and the cluster for the vehicle on which the fuse switch is turned on at the time of vehicle delivery.

The operation flow of the apparatus according to the present invention will be described in more detail as follows.

3 is a flowchart illustrating an operation flow of a method of controlling a vehicle according to the present invention.

As shown in FIG. 3, when the fuse switch is turned on (S100), the self-diagnosis controller of the vehicle performs a self diagnosis of the cluster and the control units provided in the vehicle (S200). Here, the self diagnosis operation for the cluster and each control unit will be described in more detail with reference to FIG.

4, it is assumed that the ICU is one of the control unit 110 of the vehicle's self-diagnosis control apparatus, the CLU is the cluster 10, and the BCM is one of the control units 20. [ Although only the BCM is shown in FIG. 4, any of the control units 20 included in the vehicle such as ECM, TCM, PCM, EBCM, SDM, and PSCN may be applicable.

First, the controller (ICU) 110 changes the state of the fuse switch to the ON state in the process of 'S100' in FIG. 3. Therefore, the control unit ICU 110 transmits a notification message ("C_FuseDeliveryStatus = Before Mode-> After Mode Quot;) to the cluster (CLU) 10 and the control unit 20, for example, BCM (S205, S215).

At this time, the cluster 10 and the BCM that have received the notification message from the control unit 110 force the load by the notification message to be received (S210, 220). When the load forced driving is completed, the cluster 10 and the BCM can confirm whether or not an error code, for example, a DTC is generated (S225, S250).

Also, the controller 110 sequentially transmits a drive completion confirmation message ("C_IOCBI_Finish_CLU", "C_IOCBI_Finish_BCM") to the cluster 10 and the BCM (S230, S235).

If the forced forced driving of the cluster 10 is completed, the cluster 10 may transmit a response message ("C_IOCBI_Finish_RespCLU = YES") corresponding to the message indicating completion of the drive completion (S240). On the other hand, if the load forced driving of the BCM is not completed, the BCM can transmit a response message (C_IOCBI_Finish_RespBCM = NO) to the control unit 110 (S245).

In this case, the control unit 110 transmits a drive completion confirmation message ("C_IOCBI_Finish_BCM") again after a predetermined time elapses (S255) and receives a response message (C_IOCBI_Finish_RespBCM = YES) (S260).

When all of the load of the cluster 10 and the BCM is completed, the control unit 110 can sequentially transmit a request message ("C_DTC_InfoRequest_CLU", "C_DTC_InfoRequest_BCM") requesting the error code information to the cluster 10 and the BCM S265, S270). At this time, the control unit 110 may receive a response message ("C_CLU_DTC_Info", "C_BSM_DTC_Info") corresponding to the request message from the cluster 10 and the BCM (S275, S280).

The control unit 110 can check whether the DTC has occurred in the cluster 10 and / or the BSM based on the response message received in the steps 'S275' and 'S280' (S285).

Thereafter, the vehicle's self-diagnosis control device causes the cluster 10 and the self-diagnosis results for the respective control units to be displayed on the cluster 10 (S300).

If a control unit in which a DTC has occurred is found in the process of 'S300', the cluster 10 can display the DTC of the control unit. At this time, the control unit 110 may notify the control unit of the occurrence of a problem while blinking a lamp provided in the vehicle, for example, a flasher lamp 10 times in succession.

The above processes may be implemented directly in hardware, software modules executed by a processor, or a combination of the two. The software modules may reside in storage media, such as memory and / or storage, such as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disks, removable disks, CD-ROMs. An exemplary storage medium is coupled to the processor, which is capable of reading information from, and writing information to, the storage medium. Alternatively, the storage medium may be integral with the processor. The processor and the storage medium may reside within an application specific integrated circuit (ASIC). The ASIC may reside within the user terminal. Alternatively, the processor and the storage medium may reside as discrete components in a user terminal.
