  • Motor vehicle control device data transfer system and process
    Patent number: 8035494
    Abstract: The present invention relates to a motor vehicle control device data transfer system and process. In particular, it relates to such a system and process for the transfer of data, subject to the risk of tampering, from a central data-processing device (12) at the motor vehicle manufacturer's to a motor vehicle data-processing device (5), such as an electronic drive engine control device, in which tamper-free data transfer is guaranteed. In this connection, an authentication enquiry value is generated by the vehicle data-processing device (5) and transferred to the central data-processing device (12) by means of a mobile data-processing device (9). This generates an authentication response value, which is transferred back by the same route with release data.
