Abstract

A method is described for operating a system, in particular a starter device for starting an internal combustion engine of a motor vehicle, in the system a real-time signal for achieving an activation state of an actuating device being transmitted from a controller to the actuating device via a real-time communication device with the aid of real-time interfaces. To increase flexible control of the system, for example for a start-stop operation of a vehicle, using a simple configuration, the actuating device and the controller each have a data interface via which data information is transmitted with the aid of a data communication device.

Claims

1-11. -11. (canceled)

12. A method for operating a system, comprising:

transmitting in the system a real-time signal for achieving an activation state of an actuating device from a controller to the actuating device via a real-time communication device with the aid of real-time interfaces; and

transmitting command information which determines one of the activation state or a change in the activation state together with the real-time signal so that electrical consumers are controlled by the actuating device independently of one another.

13. The method as recited in claim 12, further comprising:

in response to the command information, at least one of;

i) switching on or off a certain activation state for a given control period, ii) starting an activation state which subsequently follows according to a certain sequence of activation states, and iii) starting the certain sequence of activation states including a certain time interval of the activation states.

14. The method as recited in claim 12, wherein the actuating device and the controller each have a data interface which is different from the real-time interface and via which data information is transmitted with the aid of a data communication device, and prior to the real-time signal with respect to time, the controller transmitting data information to the actuating device via the data communication device, the data information determining at least one of:

i) an activation state, ii) a change in the activation state, iii) a control period, iv) a sequence of activation states, and v) a time interval for the sequence of activation states.

15. The method as recited in claim 12, wherein the real-time signal transmits command information which is pulse width-coded.

16. The method as recited in claim 12, wherein the real-time signal transmits command information in voltage-coded form.

17. The method as recited in claim 12, wherein the real-time signal transmits command information in coded form as an algebraic sign of an electrical voltage of the real-time signal for switching an activation state on or off.

18. The method as recited in claim 12, wherein the real-time signal transmits, in parallel, command information that is bit-coded with the aid of the real-time interfaces and a plurality of parallel communication lines of the real-time communication device, the plurality corresponding to a number of switching devices.

19. A method as recited in claim 12, wherein the system includes a starter device for starting an internal combustion engine of a motor vehicle.

20. An interface for a controller or an actuating device of a starter device of a motor vehicle for starting an internal combustion engine, the interface device having a real-time interface which is configured to transmit a real-time signal from the controller to the actuating device via a real-time communication device to achieve an activation state of the actuating device, the interface device including a data interface, which is different from the real-time interface, for a data communication device to which the controller and the actuating device are coupleable, and wherein command information which determines one of the activation state or a change in the activation state is transmittable together with the real-time signal so that electrical consumers are controllable by the actuating device independently of one another.

21. A starter device for an internal combustion engine for a motor vehicle having a system which includes a controller and an actuating device which are each coupled with the aid of real-time interfaces via a real-time communication device for transmitting a real-time signal, the real-time signal to achieve an activation state of the actuating device being transmittable from the controller to the actuating device, the controller and the actuating device each having a data interface which is different from the real-time interface and via which they are coupled to a data communication device and wherein a command information which determines the activation state or a change in the activation state is transmittable together with the real-time signal so that electrical consumers are controllable by the actuating device independently of one another.

22. A computer readable medium storing program instructions for operating a system, the program instruction when executed by a controller or actuating device, causing a system to perform the steps of:

transmitting in the system a real-time signal for achieving an activation state of an actuating device from a controller to an actuating device via a real-time communication device with the aid of real-time interfaces; and

transmitting command information which determines the activation state or a change in the activation state together with the real-time signal so that electrical consumers are controlled by the actuating device independently of one another.
