Control device reprogramming arrangement for motor vehicle, has reprogramming module for implementing reprogramming of appropriate control devices with new program data based on reprogramming protocol that is present in each control device

摘要

The arrangement has a reprogramming module (6) for implementing reprogramming of appropriate control devices (ECU1-ECU3) with new program data according to a reprogramming protocol that is present in each control device. A conversion module (TRANS) is connected with a data bus (4) and sets the new program data in the data bus by the reprogramming protocol, where the new program data is transferred to the conversion module by another reprogramming protocol. Independent claims are also included for the following: (1) a conversion module (2) a method for reprogramming two control devices.
