Description

DATA UPDATE DEVICE FOR REPROGRAMMING ECU OF AUTOMOBILE, CONNETION DEVICE AND METHOD THEREOF}

The present invention relates to a data update device for reprogramming an electronic control device of a vehicle, a connecting means and a method of operating the data update device.

In order to control the operation of the engine and other devices accurately according to each driving state of the vehicle, a plurality of electronic control units (collectively referred to as "ECUs") that perform different functions are mounted on the vehicle.

Here, the ECU operates by an algorithm set at the time of shipment of the vehicle, and data related to ECU operation or control is stored in a ROM of the ECU. The function of such ECU is rapidly developing, and the function of ECU can be newly added.

Therefore, there is a situation in which the software of the ECU is upgraded for the purpose of not only improving the function and performance of the vehicle and the ECU but also correcting the software error of the ECU. Such an operation of upgrading the software of the ECU is called reprogramming.

At this time, the ECU must be connected to an external device for reprogramming. In order to connect the external device and the ECU, the ECU is provided with a connector.

However, since the pins constituting the connector are defined with different pin numbers according to the manufacturer or type of the ECU, such a connector should have a connector having the same standard as the pin connection structure.

Conventionally, the AS technician checks a connector for an ECU to be upgraded, selects an external device (that is, an external device for reprogramming) provided with the connector, connects to the ECU, and proceeds with reprogramming. At this time, even if the same vehicle is different manufacturers or types of the ECU, it may be equipped with a connector having a different pin connection structure, in this case, it is necessary to select the external device equipped with the connector and connect to the ECU again, Quite cumbersome

In other words, the pins that make up an ECU connector differ in the function of the pin depending on the type of ECU, that is, the ECU model, the device of the ECU, and the manufacturer of the ECU. For example, if the ECU connector consists of 94 pins, the pins defined in the pins 1 to 94 are defined for use in controller area network (hereinafter, abbreviated as "CAN") communication. The number is defined differently for each ECU. Thus, to be connected with an ECU connector, it must have a pin connection structure assigned equal to the pin number of the ECU. Therefore, conventionally, each ECU must have a connector provided with a pin connection structure corresponding to a different ECU connector.

In addition, upgrading more than two ECU software at the same time is almost impossible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a data update device, a connection means, and a method of operating the data update device, which are easily connected with various connectors according to the manufacturer and / or type of the electronic control device of the vehicle.

When the can communication process S105 between the ECU 100 and the data updater 300 is started and the can communication is established through the pin in the switched-on state, the ECU reprogramming process is performed (S107).

Next, FIG. 11 is a flowchart illustrating a reprogramming process according to another exemplary embodiment of the present invention, and illustrates a reprogramming process according to the embodiments of FIGS. 4 to 6.

Referring to FIG. 11, pin information according to the ECU manufacturer and / or model is stored in the memory 311 of the data update apparatus 300 (S201). In this case, the pin information received through the update unit 317 may be stored.

Thereafter, when the ECU connector 101 and the device connector 301 are connected to the connecting means 200 (S203), the switching controller 307 outputs a selection menu through the display unit 309 (S205).

The switching controller 307 checks, from the memory 311, pin information matched to the ECU manufacturer or model selected by the user input from the input unit 311 (S207).

Then, according to the checked pin information, a control signal for turning on the switches connected to the corresponding pins 301a is output to the switching means 303 (S211).

The ECU reprogramming process is performed through can communication between the ECU 100 and the data updater 300 through the pins 101a, 201a, and 203a connected to the pin 301a in the switched-on state (S213).

The embodiments of the present invention described above are not implemented only by the apparatus and method, but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
