| 摘要 |
A system for controlling or regulating, in particular motor vehicle functions, having at least two control units which are networked to one another via a databus, in which, in order to reduce the power consumption, the system can be placed entirely or only partially in specific power consumption states (1 to 6) in which control units operate with full power consumption (1) or in a power consumption state (2 to 6) in which the power consumption is reduced. At least one control unit has a control program with an interface via which data relating to the power consumption states (1 to 6) for the optimum execution of existing application programs can be transmitted to the control program either by a program within the control unit or by an external request, the control program having means for calculating the necessary power consumption state (1 to 6) for the control unit from the data, and switchover means being provided which, when necessary, change over the control unit from one power consumption state (1 to 6) into a different power consumption state (1 to 6).
