Abstract

A method for actuating a motor-driven flap assembly of a vehicle. A control assembly is provided for actuating a motor drive assembly which is paired with the flap assembly, and a distance sensor which is coupled to the control assembly is also provided. Sensor signals are detected by the distance sensor in order to detect an operator action carried out by an operator of the vehicle, wherein the sensor signals are analyzed by the control assembly in an analysis routine in order to detect a specified operator action, and the chive assembly is actuated by the control assembly upon detecting the specified operator action. In some embodiments, when a specified charging criterion is satisfied, the analysis routine is carried out by the control assembly in a specified charging mode, in which the analysis of the sensor signals is modified on the basis of an analysis during a normal operation.

First claim

The invention claimed is:

1. A method for activating a motor-driven hatch arrangement of a motor vehicle, wherein the motor vehicle is equipped with a central, rechargeable electrical energy-storage device,
wherein a control arrangement, for activating a motor-driven drive arrangement assigned to the hatch arrangement, and a distance sensor, coupled with the control arrangement, are provided, wherein sensor signals are captured by the distance sensor for the purpose of detecting an operator action executed by an operator of the motor vehicle,
wherein the sensor signals are evaluated in an evaluation routine by the control arrangement for the purpose of detecting a specified operator action, and upon detection of the specified operator action the drive arrangement is activated by the control arrangement,
wherein when a specified charging criterion, which represents a process of charging, external to the motor vehicle, of the energy-storage device, is satisfied, the evaluation routine is carried out by the control arrangement in a specified charging mode in which the evaluation of the sensor signals is modified, proceeding from an evaluation according to normal operation.

2. The method as claimed in claim 1 , wherein the evaluation of the sensor signals in the charging mode is carried out in the evaluation routine by applying to the sensor signals a filter that has been specified for suppressing the interfering influence.

3. The method as claimed in claim 1 , wherein the specified charging criterion represents a characteristic temporal progression of an interfering influence of the external charging process on the sensor signals, and wherein by the control arrangement the temporal progression of the sensor signals is monitored for compliance with the charging criterion.

4. The method as claimed in claim 3 , wherein the charging criterion includes at least one subcriterion directed toward an amplitude value of the temporal progression of the sensor signals and/or at least one subcriterion directed toward a frequency value of the temporal progression of the sensor signals.

5. The method as claimed in claim 4 , wherein a subcriterion directed toward the amplitude value relates to an average value of the temporal progression of the sensor signals.

6. The method as claimed in claim 2 , wherein the transfer function of the filter that has been specified for suppressing the interfering influence is specified by the control arrangement in a manner contingent upon the temporal progression of the sensor signals when the charging criterion is satisfied.

7. The method as claimed in claim 2 , wherein the filter that has been specified for suppressing the interfering influence brings about a suppression of the interfering influence for sensor signals in a manner contingent upon a statistical quantity of the sensor signals that is characteristic of the operator action.

8. The method as claimed in claim 1 , wherein in the evaluation routine the sensor signals are monitored for compliance with a specified detection criterion for the purpose of detecting the specified operator action, and upon compliance with the detection criterion the specified operator action is deemed to be detected, and wherein the detection criterion is modified in the charging mode, proceeding from a detection criterion according to normal operation.

9. The method as claimed in claim 2 , wherein by the control arrangement the charging process is classified on the basis of the temporal progression of the sensor signals when the charging criterion is satisfied, and wherein the evaluation of the sensor signals in the charging mode is amended in a manner contingent upon the classification of the charging process.

10. The method as claimed in claim 1 , wherein with the external process of charging of the control arrangement a state-of-charge signal is communicated by a control unit of the motor vehicle and wherein the charging criterion is defined at least partially by the condition that the state-of-charge signal is available to the control arrangement.

11. The method as claimed in claim 1 , wherein the external charging process is carried out by a DC charging station.

12. The method as claimed in claim 1 , wherein with the motor-driven adjustment of the hatch arrangement a transfer of the hatch arrangement between a closed position and an open position is carried out.

13. A control arrangement for implementing a method as claimed in claim 1 .

14. A hatch arrangement with a hatch, the hatch arrangement exhibiting a drive arrangement and a control arrangement as claimed in claim 13 .

15. The method as claimed in claim 2 , wherein the filter that has been specified for suppressing the interfering influence is provided in combination with at least one preliminary filter provided in accordance with normal operation, and/or with modification of a preliminary filter.

16. The method as claimed in claim 5 , wherein this subcriterion is defined by the condition that the average value of the temporal progression of the sensor signals exceeds a specified temporal offset.

17. The method as claimed in claim 6 , wherein the transfer function is specified in a manner contingent upon the compliance with the subcriterion directed toward an amplitude value and/or frequency value of the temporal progression of the sensor signals.

18. The method as claimed in claim 7 , wherein the specified filter brings about a suppression of the interfering influence for sensor signals having a statistical quantity below a specified threshold value.

19. The method as claimed in claim 9 , wherein the filter that has been specified for suppressing the interfering influence is specified in a manner contingent upon the classification.

20. The method as claimed in claim 1 , wherein with the external process of charging of the control arrangement a state-of-charge signal is communicated by a control unit of the motor vehicle by the central control system of the motor vehicle, and wherein the charging criterion is defined at least partially by the condition that the state-of-charge signal is available to the control arrangement.
