摘要

The system has a secured remote server (10) in which a file (11) to be downloaded is stored. The server is connected by a data transmission network (12) e.g. Internet type network, to a local downloading tool (13) that is to be connected to a logic controller (14) embarked inside a motor vehicle, by a multiplex transmission network (15). The tool has communication units for exchanging data with the controller and the server. An independent claim is also included for a method for downloading a file in a controller/computer embarked inside a motor vehicle.
