Electronic control device and electronic control system
First Claim
1. An electronic control device installed in a vehicle configured to control a transmission of vehicle diagnostic data to an external vehicle data management center, the electronic control device comprising:
- a microcomputer configured to interface with vehicle sensors to accumulate vehicle diagnostic data from the vehicle sensors and actuators and to store the vehicle diagnostic data into a memory in response to a diagnostic request signal from an external diagnostic device, wherein the microcomputer is further configured todetect an ON state and an OFF state of a vehicle ignition switch and detect a vehicle diagnostic data transmission request from the external vehicle data management center,in response to the microcomputer detecting the vehicle diagnostic data transmission request, transmit the vehicle diagnostic data stored in the memory to a vehicle communication module, and whereinthe microcomputer is in connection with a dedicated connector within the vehicle, the dedicated connector is configured to connect to the external diagnostic device or another external device,the microcomputer is further configured to detect a connection of the external diagnostic device or the other external device to the dedicated connector, andin response to the microcomputer detecting the vehicle diagnostic data transmission request and the connection of the external diagnostic device or the other external device to the dedicated connector, the microcomputer transmits the vehicle diagnostic data stored in the memory to the vehicle communication module when the microcomputer detects the OFF state of the vehicle ignition switch.

Abstract
An electronic control device (ECU) reserves a transmission of a requested diagnosis data that is requested by a management center when an external device is connected to a dedicated connector, and when IGSW is turned ON. In such scheme, a delay of an off-board diagnosis process in the ECU is prevented when a diagnosis tool connected to the dedicated connector performs an off-board diagnosis. Further, after turning OFF of IGSW, the ECU, which is no longer due for a request from the external device connected to the dedicated connector, transmits the requested diagnosis data to the center, enabling the center to perform a remote diagnosis service. 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.
