A system for transmitting at least one upgrade package for at least one control device of a motor vehicle is provided. The system includes a storage device external to the motor vehicle that stores the upgrade package, as well as a communication device that wirelessly transmits the upgrade package from the storage device external to the motor vehicle to at least one transmission device of the system. The transmission device conducts a transmission process of the upgrade package for the at least one control device and installs the upgrade package on the at least one control device. The at least one transmission device is arranged internally in the motor vehicle.

System for transmitting at least one upgrade package for at least one control device of a motor vehicle and method

A system and method for operating a remote control having a portable remote control unit which can control at least one function unit. The remote control unit and the function unit are connected with one another by way of a bidirectional data communication link, by which data can be transmitted by means of a symmetrical coding method. The remote control unit sends a learn mode reporting signal in a secret coding information learn mode to the controllable function unit which, in the learn mode, in turn, sends back an acknowledgment signal. Upon receipt of the acknowledgment signal, the remote control unit generates new secret coding information by means of the coding algorithm, as a function of basis secret coding information and of the previous secret coding information, and sends the new secret coding information to the function unit. The function unit then replaces the previous secret coding information with the new secret coding information and emits an acknowledgment signal, upon the receipt of which the remote control unit, in turn, replaces the previous secret coding information with the new secret coding information.
