Abstract

An electronic control device (ECU) refrains from a transmission of a requested diagnosis data while IGSW is turned ON in case that an external device is connected to a dedicated connector. After turning OFF of IGSW, regardless of the connection of the external device to the connector, the transmission of the requested diagnosis data to the center is performed. As a result, a delay of an off-board diagnosis process in the ECU due to the transmission of the diagnosis data is prevented. Further, the data required for performing a remote diagnosis service is regularly transmitted to a management center. Therefore, the remote diagnosis service is performable when a commercially-available external device is connected to the dedicated connector by a user of a vehicle.

Claims

1. An electronic control device installed in a vehicle for performing a predetermined control process, the electronic control device configured to comprise:

an off-board diagnoser performing an off-board diagnosis in response to a request from an external device that is connected to a dedicated connector providing a connection to the external device; and

a diagnosis data transmitter (i) generating a diagnosis data to be transmitted to an external management center and (ii) transmitting the generated diagnosis data to the external management center, wherein

operation of the electronic control device is continued by receiving a power supply after a turning OFF of an ignition switch of the vehicle, and

the diagnosis data transmitter is configured to;

(a) refrain from transmitting the diagnosis data to the external management center while the ignition switch of the vehicle is turned ON; and

(b) transmit the diagnosis data after the turning OFF of the ignition switch,

in case that the external device is connected to the connector.

2. The electronic control device of claim 1, wherein

the diagnosis data transmitter generates and transmits the diagnosis data to the external management center in response to a reception of a transmission request.

3. The electronic control device of claim 2 further comprising:

an output device provided in the vehicle and outputting the transmission request of the diagnosis data to the diagnosis data transmitter based on the turning OFF of the ignition switch.

4. The electronic control device of claim 1, wherein

the electronic control device continues to receive a power supply for at least a preset amount of time after the turning OFF of the ignition switch.

5. The electronic control device of claim 1, wherein

the electronic control device controls a power supply continuation time after the turning OFF of the ignition switch, and

the diagnosis data transmitter continues to receive the power supply until transmission of the diagnosis data is complete, based on the control of the electronic control device, when the diagnosis data transmitter transmits the diagnosis data after the turning OFF of the ignition switch.

6. The electronic control device of claim 1 further comprising:

a detector detecting whether the external device is connected to the connector.

7. The electronic control device of claim 6, wherein

the detector detects a disconnection of the external device from the connector, when a preset amount of time lapses after receiving the request from the external device.

8. An electronic control system including an electronic control device installed in a vehicle for performing a predetermined control process, the control system comprising:

an off-board diagnoser performing an off-board diagnosis in response to a request from an external device that is connected to a dedicated connector providing a connection to the external device;

a communicator communicating with an external management center;

a diagnosis data transmitter (i) generating a diagnosis data and (ii) transmitting the generated diagnosis data to the external management center by using the communicator; and

a power supplier supplying an electric power to the electronic control system, the supply of the electric power continuing after a turning OFF of an ignition switch of the vehicle, wherein

the diagnosis data transmitter is configured to;

(a) refrain from transmitting the diagnosis data to the external management center while ignition switch of the vehicle is turned ON; and

(b) transmit the diagnosis data after the turning OFF of the ignition switch,

when the external device is connected to the connector.

9. The electronic control device of claim 8, wherein

the diagnosis data transmitter generates and transmits the diagnosis data to the external management center in response to a reception of a transmission request.

10. The electronic control device of claim 9 further comprising:

an output device provided in the vehicle and outputting the transmission request of the diagnosis data to the diagnosis data transmitter based on the turning OFF of the ignition switch.

11. The electronic control device of claim 8, wherein

the power supplier continues a power supply for at least a preset a of time after the turning OFF of the ignition switch.

12. The electronic control device of claim 8, wherein

the power supplier continues the power supply until transmission of the diagnosis data is complete, based on the control of the electronic control device, when the diagnosis data transmitter transmits the diagnosis data after the turning OFF of the ignition switch.

13. The electronic control device of claim 8 further comprising:

a detector detecting whether the external device is connected to the connector.

14. The electronic control device of claim 13, wherein

the detector detects a disconnection of the external device from the connector, when a preset amount of time lapses after receiving the request from the external device.
