Abstract: A method for executing a driving task in a decentralized control unit system and a decentralized control unit system are provided. The control unit system includes at least two control units that are designed as senders, and at least one control unit that is designed as a receiver. The at least two senders and the at least one receiver in each case have activity states and operating states. The two senders and the receiver in each case check their own activity states. The two senders' own activity states are compared to the receiver's own activity state. An evaluation of operating states is carried out if the two senders' and the receiver's own activity states are in each case error-free. The driving task is executed if one of the two senders and the receiver in each case has a dynamic operating state.

Abstract: A method for diagnosing a function of an internal combustion engine, which includes one injector of an intake-manifold injection, one injector of a direct injection and one cylinder. Fuel may be applied to the cylinder with the aid of the injector of the intake-manifold injection and/or with the aid of the injector of the direct injection. The method includes the steps of determining an operating state of the internal combustion engine, which is characterized by an injection and/or injections used for injecting fuel into the cylinder, selecting a diagnostic function for the cylinder as a function of the determined operating state and carrying out the selected diagnostic function for the cylinder.
