Data-transmission method for transferring data between control units in a motor vehicle, uses control units to prepare and exchange encoded data records for vehicle functions

A first control unit (SE1) prepares encoded data records (DV1,DV2) from parts of data to be transferred. A second control unit (SE2) for preparing encoded data records transmits codes (Sch1-Sch3) to the first control unit, which transmits the encoded data records to the second control unit. The firs...

Beschreibung
Zusammenfassung:	A first control unit (SE1) prepares encoded data records (DV1,DV2) from parts of data to be transferred. A second control unit (SE2) for preparing encoded data records transmits codes (Sch1-Sch3) to the first control unit, which transmits the encoded data records to the second control unit. The first control unit transmits second data records (DU1,DU2) to the second control unit with a part of the data to be transmitted. The second control unit compares the data records. An Independent claim is also included for a device for transferring data between control units in a motor vehicle. Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Übertragung von Daten zwischen mindestens zwei Steuereinheiten (SE1, SE2) in einem Fahrzeug, wobei die erste Steuereinheit (SE1) einen verschlüsselten Datensatz (DV1, DV2) aus mindestens einem Teil der zu übertragenden Daten erstellt, die zweite Steuereinheit (SE2) mindestens einen Schlüssel (Sch1, Sch2, Sch3) für die Erstellung des verschlüsselten Datensatzes (DV1, DV2) an die erste Steuereinheit (SE1) sendet und die erste Steuereinheit (SE1) mindestens den verschlüsselten Datensatz (DV1, DV2) an die zweite Steuereinheit (SE2) sendet.
