SYSTEM AND METHOD FOR REPROGRAMMING ECU DEVICES (ELECTRONIC CONTROL UNITS) IN VEHICLES, VIA DIGITAL RADIO

The invention relates to a system and method for the reprogramming of ECU devices in automotive vehicles, via digital radio, which allows new software files to be transmitted when synchronizing a radio station, automatically and safely downloading the new updates without having to take the vehicle directly to a dealership, characterized by comprising means for encrypting audio files with software files, data files with vehicle information files; means for mixing the files to be transmitted simultaneously from a radio broadcast station in digital format; means for receiving the files by digital radio receiver that are sent to receiving ECUs in the vehicles; memory means for storing said files; means for demodulating the files; means for decrypting the files that are retransmitted within the bus of the ECU device through the internal network of the vehicle, so that all ECUs receive the message simultaneously and, after authenticating the information, auto-reprogram with the software file received in an application memory.
