Definitions

• the invention relates to a method for reprogramming of a device having a control unit, in particular of radio signal processing in motor vehicles.
• Radio signal processing is currently used in today's Motor vehicles are increasingly used to the driver for example Data about the current traffic situation for To make available. So it is already possible today the position of the vehicle based on the data received to determine with high accuracy and with digitized Compare road maps so that the driver can be directed to a predetermined destination.
• the known systems allow rapid availability and thus ensure increased driving safety and increased comfort.
• RDS Radio data system
• the disadvantage here is that the fast progressive development in the field of such telematics systems comparatively often an adjustment of the system, in particular the radio signal processing of the vehicle must be made to always have an optimal Use of the data transmitted by means of the radio signal to reach. This must be done by loading an updated Radio signal processing program the radio signal processing be brought up to date, which is often the case can only be carried out by a specialist workshop.
• the problem underlying the invention is a method for reprogramming a control unit Device, in particular a radio signal processing a Motor vehicle so that to a workshop stay to update the control unit controlling programs can be dispensed with.
• This problem is solved according to the invention in that with a radio signal a data record of the control unit is changed.
• This allows the adjustment of the Processing in the control unit using the means of the radio signal transmitted to the radio signal processing Data are made.
• the data transmission made on the control unit during operation so that no downtimes occur Workshop visits must be provided.
• data from a digitized road map flows for the driver unnoticed in the control unit flow and can be brought up to date become.
• This can also be done for trips abroad, for which automatically additional traffic regulations apply received and, for example, in a speed control system can flow in or automatically the low beam is switched on by the control unit will be as prescribed in Scandinavian countries is.
• One embodiment of the invention is special advantageous in which with the radio signal the data set one Program codes of the control unit is changed. Thereby can intervene directly in the control unit and so when the vehicle control for the driver changes can be made unnoticed. With help Such programs become the essential processes in the vehicle such as braking systems, airbags, electronic Suspension systems etc. regulated and monitored so that easy change by changing the program code in essential areas of the vehicle and thus effective optimization is made possible.
• Control unit around an engine control of the motor vehicle acts.
• the engine control can constantly adapted to the latest specifications and, for example, the Fuel consumption can be reduced.
• This can also affect the environment be taken into account and for example a coordination of the engine control for summer or winter operation be made.
• a further development of the invention is particularly simple, in which the control unit for receiving radio signals a radio data system (RDS) is formed.
• RDS radio data system
• control unit receives trained by radio signals from a mobile phone system is.
• control unit receives a signal in particular to confirm the radio signal received, triggers.
• This allows the sender of the Radio signals that data has been transmitted to the receiver of the radio signal. It can also be done at the same time a feedback of the changes made to the data record or other vehicle-specific data the current state of the vehicle serve as the basis for subsequent radio signals. Farther can result in incorrect transmission of data be recognized immediately.
• the driver can the data transmission and the change made to the Record, for example by means of a display pointed out become.
