Abstract

A method is described for operating a controller for a starting apparatus for starting an internal combustion engine in a vehicle, the controller controlling an engagement apparatus, which encompasses the starting apparatus, so as to engage a starter pinion into the ring gear of an internal combustion engine, in particular using a start-stop operating strategy. In order to improve vehicle convenience by the fact that start-stop operation can be implemented with quick and reliable availability of the internal combustion engine, at least one operating parameter of the engagement apparatus is sensed and evaluated by the controller, and the controller adapts the control of the engagement apparatus to the at least one operating parameter.

Claims

1-12. -12. (canceled)

13. A method for operating a controller for a starting apparatus for starting an internal combustion engine in a vehicle, the controller controlling an engagement apparatus, which encompasses the starting apparatus, so as to engage a starter pinion into a ring gear of the internal combustion engine using a start-stop operating strategy, the method comprising:

sensing at least one operating parameter of the engagement apparatus, wherein the engagement apparatus is used by the controller as a sensor of the at least one operating parameter to determine at least one of a temperature of the engagement apparatus, a position of the engagement apparatus, and a speed of the engagement apparatus;

evaluating, by the controller, the at least one operating parameter; and

adapting, by the controller, the control of the engagement apparatus to the at least one operating parameter;

wherein the engagement apparatus has two separately energizable and detectable windings, and the controller encompasses a measurement and evaluation apparatus.

14. The method as recited in claim 13, wherein the temperature of the engagement apparatus is sensed as an operating parameter.

15. The method as recited in claim 13, wherein the controller adapts the control by way of at least one settable control parameters, at least one of the control parameters including at least one of a control instant and a control power output.

16. The method as recited in claim 13, wherein at least one control parameter used by the controller to control the engagement apparatus is ascertained by the controller from at least one dependent variable operating parameter via a stored characteristic curve.

17. The method as recited in claim 16, wherein the at least one control parameter is ascertained by the controller from at least one dependent variable operating parameter via a stored characteristic curve with respect to at least one operating parameter reference value, by shifting the characteristic curve with respect to the reference value.

18. The method as recited in claim 16, wherein the at least one control parameter is ascertained from a multidimensional characteristics diagram.

19. The method as recited in claim 16, wherein the at least one control parameter is ascertained from a temperature model, and the at least one operating parameters includes at least one of a position of the starter pinion and speed of the starter pinion, calculated by integration, and the sensing includes sensing armature position and advance distance.

20. The method as recited in claim 19, wherein parameters are learned in relation to operating parameter values.

21. The method as recited in claim 20, wherein the at least one of control parameter is ascertained as a function of the temperature, the pinion position, and the pinion speed.

22. The method as recited in claim 21, wherein a temperature-dependent extension time span of the starter pinion is compensated for one of by a variable control, or by regulation of the control power level.

23. A storage medium storing a computer program having program instructions that is loadable into a program memory, the computer program for operating a controller for a starting apparatus for starting an internal combustion engine in a vehicle, the controller controlling an engagement apparatus, which encompasses the starting apparatus, so as to engage a starter pinion into a ring gear of the internal combustion engine using a start-stop operating strategy, the computer program, when executed by a controller, causing the controller to perform the steps of:

sensing at least one operating parameter of the engagement apparatus wherein the engagement apparatus is used by the controller as a sensor of the at least one operating parameter to determine at least one of a temperature of the engagement apparatus, a position of the engagement apparatus, and a speed of the engagement apparatus;

evaluating, by the controller, the at least one operating parameter; and

adapting, by the controller, the control of the engagement apparatus to the at least one operating parameter;

wherein the engagement apparatus has two separately energizable and detectable windings, and the controller encompasses a measurement and evaluation apparatus.

24. A controller for a starting apparatus having a starter motor, a starter relay, and a starter pinion that can be extended and retracted by the starter relay, start-stop operation of an internal combustion engine being implemented with the controller, and the starter relay and the starter motor being controllable separately and in defined fashion by the controller, the controller including a sensing device for operating parameters and an evaluation apparatus with variable power level control of the starter relay in order to regulate in compensated fashion a temperature-dependent extension time span of the starter pinion, the controller configured to control an engagement apparatus, which encompasses the starting apparatus, so as to engage the starter pinion into a ring gear of the internal combustion engine, the engagement apparatus being used by the controller as a sensor of the at least one operating parameter, the at least one operating parameter being at least one of a temperature of the engagement apparatus, a position of the engagement apparatus, and a speed of the engagement apparatus, the engagement apparatus having two separately energizable and detectable windings, and the controller encompassing a measurement and evaluation apparatus.
