Abstract: A method for operating a control unit of a motor vehicle, wherein a state management module of a runtime environment initiates a standby mode of the runtime environment as a function of a stop request. The invention provides that, as a function of the stop request, the state management module first sends out to at least one application a respective backup request which requests the respective application to store respective predetermined runtime data in a non-volatile data memory, and then, however, if a resume request is subsequently received within a waiting time period, the normal operating mode is continued without the planned switch-over to the standby mode.

Abstract: In a motor vehicle, messages from control units arrive at input ports of a switch apparatus with each message indicating a destination address and a priority level. Each input port of the switch apparatus receives at most messages with a predetermined maximum data volume overall, for one priority level or for some or all of the priority levels, during each predetermined unit of time. The received messages are assigned to output port(s) based on their destination address and the messages assigned to each output port are sent onward. This guarantees time limits for the respective transmission period.

Abstract: A technique is specified for configuring an electronic control unit having intercommunicating applications which have been arranged in various partitions and to which differing safety integrity levels have been assigned. According to one method aspect, the communications behavior of the applications assigned to the differing partitions amongst themselves is analyzed, in order to identify data-writing and data-reading applications that are not located in the same partition. Subsequently, a shared memory area for the intercommunicating applications is configured, and a to communications data structure for the applications is generated. The communications data structure is at least partially arranged in the shared memory area.
