1 is a block diagram schematically illustrating a configuration of an electronic controller update system including an electronic controller update terminal 100 of a vehicle according to an exemplary embodiment of the present invention.

More specifically, FIG. 1 shows that the electronic control device update terminal 100 downloads the electronic control device update software from the update management server 110, and after the type of the electronic control device update software is downloaded, key-off of the vehicle. The power control signal is transmitted to the microcomputer 120 so that power is not cut off from the vehicle battery 125, and the electronic controller 125 is updated with the electronic controller update software.

The update management server 110 may transmit a software update request to the update terminal 100 to download the electronic controller update software when there is a matter to be updated for the software of the electronic control apparatus 125 in the vehicle. At this time, the update management server 110 transmits an update request message to the owner's portable terminal, receives the update consent message from the owner's portable terminal, and then causes the update terminal 100 to download the electronic controller update software. Can be.

Thus, when the download of the electronic controller update software is completed, the update terminal 100 may transmit a power maintenance signal to the microcomputer 120 that controls the power in the vehicle. The microcomputer 120 receiving the power maintenance signal controls the power to be cut off from the battery 130 in the vehicle. In addition, the update terminal 100 updates the electronic controller 125 by using the downloaded electronic controller update software.

2 is a block diagram illustrating a configuration of an electronic control apparatus update terminal 100 of a vehicle according to an exemplary embodiment of the present invention.

In more detail, Figure 2 shows a detailed configuration of the electronic control device update terminal 100 shown in FIG. 1, each of which is merely a configuration for explaining an embodiment of the present invention, the present invention The technical features are not limited only to the implementation method shown in FIG.

2, the electronic control device update terminal 100 according to the embodiment of the present invention, the communication module 220, the implementation unit 230, the storage unit 240, the power control unit 250 and And a display unit 260 and a control unit 210 for controlling the respective components.

The communication module 220 of the present invention serves to enable the electronic control device update terminal 100 to be connected to the update management server 110 through a communication network or a direct network.

The implementation unit 230 according to the embodiment of the present invention, when there is software for updating the electronic control device stored in the storage unit 240, updates the electronic control device 125 after the vehicle is keyed off. Play a role. At this time, the display unit 260 may display whether or not to update the electronic control apparatus 125 and receive an update request, and then update may be performed.

In addition, when the update of the electronic controller 125 is completed or not normally completed, the update result message may be transmitted to the owner's portable terminal or the update management server 110. In addition, when the update management server 110 receives information on the existence of software to update the electronic control device from the update management server 110, it displays on the display unit 260 the intention of executing the update on the display unit 260 or After transmitting the update request message to the mobile terminal, and receiving the update agreement message, the communication module 220 can be made to download the software to perform the update of the electronic control device.

In addition, when the inspection software is downloaded together with the software for updating the electronic control apparatus, the electronic control apparatus 125 performs the update after determining whether the software for performing the update is normally operated through the inspection software. can do.

The storage unit 240 according to an embodiment of the present invention plays a role of downloading and storing software for updating the electronic control apparatus 125 from the update management server through the communication module 220.

In addition, the storage unit 240 determines whether the software for updating the electronic controller 125 is normally operated in the electronic controller 125 together with the software for updating the electronic controller 125. You can also download the test software for verification.

The power control unit 250 according to the embodiment of the present invention, if there is software to update the electronic control device 125 in the storage unit 240, after the key off of the vehicle the electronic control device 125 The power maintenance signal may be transmitted to a microcomputer controlling the power supply in the vehicle to perform the update of the vehicle.

At this time, the power control unit 250 calculates the time required for the update according to the capacity of the software for performing the update of the electronic control device 1250 stored in the storage unit 240, or information on the required time By extracting the information can be transmitted along with the power maintenance signal on the power holding time. The calculation method for the required time may vary depending on the type of software, the performance of the electronic control device update terminal 100, and the like.

The display unit 260 according to the exemplary embodiment of the present invention may be formed of a touch panel, a liquid crystal display panel, or the like, and performs a function of displaying a screen so as to facilitate control of the update or check the update status.

3 is a flowchart illustrating a process of updating an electronic control apparatus of a vehicle according to an exemplary embodiment of the present invention.

First, before executing the update of the electronic control device 125, the software to perform the update is downloaded in advance from the update management server 110. In this case, it is not necessary to directly download the software to perform the update directly from the update management server 110, it may be received from a separate device. In addition, the user may proceed with the download after confirming the intention of downloading the software to update the borrower by inputting through the display unit 260 or receiving a consent message from the borrower's portable terminal before performing the download (S310).

After the download of the software to be updated is completed, if the vehicle is in a key-off state after the vehicle operation is terminated (S320), it is determined whether there is software to be updated in the storage unit 240. If the update target software does not exist, the power in the vehicle is cut off (S330). Of course, it is irrelevant to let the power inside the vehicle to be cut off naturally without any further action. On the other hand, if there is an update target software (S335), the power controller 250 transmits a power maintenance signal to the microcomputer 120 that controls the power in the vehicle. At this time, the update time required according to the type and capacity of the software to perform the update and the performance of the electronic control device update terminal 100 together with the power maintenance signal may be calculated and transmitted together with information on the power maintenance time (S340). ).

When the power in the vehicle is maintained in the key-off state of the vehicle through the operation S340, the electronic controller 125 updates the software through the implementation unit 230 to perform the update. In this case, the user may perform an update after confirming the intention of whether or not to update the owner through an input through the display unit 260 before performing the update (S350).

Thereafter, when the update is completed or not normally completed, the update result message may be transmitted to the update management server 110 or the next portable terminal (S360).

When all the processes for the update are completed, the power in the vehicle is cut off by the microcomputer controlling the power in the vehicle (S370).
