Description

Remote Log Collection Device and Method for Reprogramming Tool for Vehicle Controller Embodiments of the present invention relate to an apparatus and method for remote log collection of a vehicle controller reprogramming tool. In recent vehicles, most nodes of the vehicle network are composed of ECUs (Electronic Control Units), such as the BCM/ETACS (Body Control Module/Electronic Time & Alarm Control System) that controls electrical and chassis components, the ABS ECU (Anti-lock Brake System Electronic Control Unit), the engine ECU, and the airbag ECU. These ECUs receive vehicle diagnostic services for safe and economical operation, which enables the prevention of vehicle breakdowns in advance and provides various vehicle information, such as driving record management and statistical data. In addition, the ECUs receive software upgrades, or reprogramming, as needed to change specifications or upgrade functions. If a firmware update is required for the vehicle controller, perform the update using reprogramming equipment. If a problem occurs during the reprogramming process, extract and deliver the log files for cause analysis. Copy and deliver the log files stored within the reprogramming tool using a USB storage device. If delivery via USB is difficult, deliver the reprogramming equipment itself or connect it directly to a laptop. Under the existing method, additional user work is required to extract log files when a problem occurs with the automotive controller reprogramming tool. Copying and delivering files to a USB storage device results in lengthy root cause analysis. Furthermore, in most cases, USB storage devices are difficult to use due to removable media security policies. Even delivering the reprogramming device itself requires significant time for analysis. To analyze the device by directly connecting a laptop, development personnel must visit the site.
