However, in FIG. 2, the communication device 200 is described as a separate electric component, and the communication device 200 may be formed as a separate electric component, but the charging terminal 300 and the communication unit installed in the vehicle 100 ( 310), including the control unit 320 and the display unit 330 may perform vehicle monitoring control when the vehicle is in a charged state.

When a separate communication device 200 is formed, a charging terminal 300, a control unit 320, and a display unit 330 may be formed on various electric components 130 of a vehicle, and communication may be performed through CAN communication. An operation according to the communication control of the device 200 may be performed.

As will be described later, various configurations included in the control block diagram of the vehicle of FIG. 3 will be described.

The charging terminal 300 includes a charging socket 104, and the charging connector 152 of the external slow charger 150 is connected to the entire socket 104 to charge the high voltage battery 102. That is, when the charging connector 152 of the slow charger 150 is connected to the charging socket 104 of the vehicle 100, the high voltage battery 102 of the electric vehicle 100 is charged.

In particular, the vehicle 100 is connected to the charging connector 152 of the slow charger 150 through the charging socket 104, and the charging connector 152 internally transmits charging information through PLC communication and performs charging control. It is possible to do.

Accordingly, the vehicle 100 measures an output frequency by including an inlet device (charge terminal) that includes a vehicle-side PLC communication power connected to the charging connector 152. As will be described later in detail in FIG. 3, when the vehicle 100 is charged through the charging socket 104, the gateway included in the communication unit 310 of the vehicle is charged from CAN controllers and chargers applied to the vehicle. Charge control may be performed by transmitting information.

At this time, the communication unit 310 may further include a PLC communication unit 312, a CAN communication unit 313, and a wireless communication unit 314 in addition to the gateway 311.

The gateway 311 transmits charging information received from the various charger components and the slow charger 150 and communicates with each other through CAN communication applied to the vehicle, and performs charging control. That is, the gateway 311 for controlling charging in the vehicle 100 is connected to various ECUs (Electronic Control Units) included in the vehicle through the CAN communication unit 313, and through the PLC communication unit 312. While charging in the vehicle through connection with the fast charger 150, the vehicle status monitoring and diagnostic signals are processed.

The PLC (Power Line Communication) communication unit 312 enables wired communication so that charging information from the slow charger 150 can be transferred to the vehicle 100. In addition, the PLC communication unit 312 according to an embodiment of the present invention may control charging / diagnostic information of a vehicle and state information of a vehicle through an Ethernet message.

The CAN communication unit 313 transmits charging information and control information obtained through the PLC communication unit 312 to various electric components 130 inside the vehicle.

For example, the CAN communication unit 313 can transmit a control signal by performing CAN communication to display charging information obtained through the PLC communication unit 312 on the display device 136 of the vehicle.

The wireless communication unit 314 enables communication with a wireless device outside the vehicle other than the slow charger 150.

It may include a supported wireless communication module.

For example, when the vehicle 100 charges the slow charger 150 when the vehicle 100 is charging, the wireless communication unit 314 transmits to the user terminal that a failure problem occurs that cannot monitor and update the vehicle. It may be possible.

Further, the wireless communication unit 314 may acquire update information from the vehicle service center through wireless communication when a vehicle update is required when charging with the slow charger 150.

Next, the control unit 320 controls the vehicle as a whole. Specifically, the control unit 320 analyzes the diagnostic information from the charging information obtained through the communication unit 310, the diagnostic information of the vehicle, and the status information of the vehicle, and updates the vehicle based on the analyzed diagnostic information, whether the vehicle Decide if you need to visit a service center.

For example, FIG. 4 is an exemplary view of a screen displaying a service provided when charging a vehicle according to an embodiment. Specifically, FIG. 4 (a) is a schematic diagram showing a screen displaying real-time charging information, and FIG. 4 (b) is a schematic diagram showing a screen displaying vehicle status check.

For example, as shown in FIG. 4 (a), the control unit 320 may control to display the charging information obtained through the gateway 311 on the display unit 330. For example, the control unit 320 may display remaining time until completion of charging, current charge amount information, and the like, and display a service that the user can select until charging is completed. Specifically, it may be displayed so that the user can select whether to forcibly terminate the charging, check the vehicle status, or provide delivery service.

Accordingly, when the user selects the vehicle status check, the control unit 320 requests the vehicle charger to diagnose the slow charger 150. That is, the control unit 320 may transmit information through the gateway 311 and the PLC communication unit 312 of the communication unit 310 to transmit the vehicle diagnosis request message to the slow charger 150.

For example, according to an embodiment of the present invention, the gateway 311 transmits vehicle status check request information to the slow charger 150 and performs monitoring and routing functions of the vehicle status. That is, through the gateway 311, the control unit 320 may collect diagnosis and status information of the overall electric device 130 belonging to the vehicle.

Therefore, the slow charger 150 that acquires the vehicle status check request information is a slow charger 150 and a server (not shown) that can be connected to the wireless or wired, analyzes the vehicle data, determines whether software update is possible, and then the slow charger The 150 provides a software update function or a warning light / fault code erasure function so that the software update required for the vehicle 100 is possible.

Accordingly, the vehicle 100 connected to the slow charger 150 may perform software update.

For example, as shown in FIG. 4 (b), the control unit 320 of the vehicle 100 includes battery status information (98%), charging performance (100%), and an electric device included in the vehicle 100 ( 130) It is possible to indicate that a software update of a motor requiring an update is possible. In addition, it is possible to display a remaining date until the current vehicle 100 is periodically inspected so that the user can determine whether or not the motor software is available.

Accordingly, the control unit 320 may provide a software update function to the vehicle electronic device 130 that needs improvement through analysis and diagnosis of vehicle data through a server connected to the slow charger 150.

Accordingly, even when the vehicle cluster warning is activated internally in the vehicle 100, if it is determined that software update is unnecessary, the controller 320 may release the vehicle cluster warning light or provide a failure diagnosis erase function.

In addition, when charging the vehicle with the slow charger 150, the vehicle 100 may provide a service center notification (eg, maintenance reservation) function to the user when software update support is not available.

The disclosed embodiments can be implemented in the form of a recording medium that stores instructions executable by a computer. Instructions may be stored in the form of program code, and when executed by a processor, may generate program modules to perform operations of the disclosed embodiments. The recording medium may be embodied as a computer-readable recording medium.

The computer-readable recording medium includes all kinds of recording media storing instructions that can be read by a computer. For example, there may be a read only memory (ROM), a random access memory (RAM), a magnetic tape, a magnetic disk, a flash memory, and an optical data storage device.

In the above, the functions related to the monitoring of the vehicle and the software update of the vehicle interior electronic device 130 when the vehicle 100 is charged through the slow charger 150 have been described.

Hereinafter, a vehicle monitoring operation method when the vehicle 100 is charged through the slow charger 150 will be described. Specifically, FIG. 5 is a flowchart illustrating a vehicle monitoring operation method when the vehicle 100 is charged.

First, vehicle monitoring is possible when the vehicle 100 is connected to the slow charger 500.

At this time, the vehicle 100 may display the display unit 330 to enable the user to select whether to use the diagnostic function through the slow charger 150. At this time, the display unit 330 may allow a user to select whether to use the diagnostic function through a touch input, but is not limited thereto.

If the user inputs that the user does not use the diagnostic function (NO in 510), the vehicle 100 simply performs the charging function through the slow charger 150 (515).

However, when a user inputs that a user intends to use the diagnostic function (YES in 510), the vehicle 100 performs vehicle monitoring control (520). Specifically, the vehicle monitoring control is performed based on communication through the slow charger 150 to perform charging control signal routing 521 to enable vehicle monitoring, and to various electric equipments 130 included in the vehicle 100 For the monitoring 522, the charging function is also performed at the same time (523).

At this time, the slow charger 150 transmits the diagnostic result analysis information to the vehicle 100, so that the vehicle 100 obtains the diagnostic result analysis information. Accordingly, the in-vehicle control unit 320 determines whether a problem with the vehicle can be solved through the diagnosis result (550). However, even if the problem can be solved, if a user's intention not to repair a problem in the vehicle is input through the vehicle input unit, as in the case where a doctor not to use the diagnostic function is input (No in 510), the vehicle is simply 100 ) Can only perform the charging function through the slow charger 150.

However, in other cases, when the controller 320 determines that the vehicle problem can be solved (YES in 550), the failure notification for the ECU having the problem is released.

However, unlike this, if the controller 320 determines that the vehicle problem is not a state in which it can be solved (No in 550), the controller 320 determines whether the ECU software having the problem is updatable (560) . At this time, if software update is possible (YES in 560), the controller 320 updates the software of the corresponding ECU (565). However, if the software update is not possible (No in 560), it is determined that the problem of the failure cannot be solved in the current charging state, and a warning alerting the user of a service center is displayed (570).

However, regardless of whether the vehicle problem can be solved when charging through the slow charger 150, the vehicle 100 is disconnected (580).

As described above, the disclosed embodiments have been described with reference to the accompanying drawings. Those skilled in the art to which the present invention pertains will understand that the present invention may be practiced in different forms from the disclosed embodiments without changing the technical spirit or essential features of the present invention. The disclosed embodiments are illustrative and should not be construed as limiting.
