Abstract

A method for operating a door actuator of a pivot leaf door, having a pivotable door leaf, includes at least the following steps: performing a pivot movement of the door leaf; and identifying an interaction between the door leaf and a person and determining a correction value for the pivot movement of the door leaf based on the interaction and correcting future pivot movements of the door leaf by the correction value. A door actuator of a door system is configured to carry out the method.

First claim

The invention claimed is:

1 . A method for operating a door actuator of a door system, having a pivotable door leaf, the method including the following steps:
performing a pivot movement of the door leaf, identifying an interaction between the door leaf and at least one person, determining a correction value for the pivot movement of the door leaf based on the interaction, and correcting future pivot movements of the door leaf by the correction value, wherein the interaction between the door leaf and the at least one person is one of pushing the door leaf, an interruption of the walking movement, a slowing down of the walking movement, a stopping of the walking movement, and an acceleration of the walking movement,
wherein the correction values are optimized in a correction value memory via an algorithm over the initial service life of the pivot leaf door by the correction values for future pivot movements of the door leaf being defined in a prioritized manner such that the future number of interactions between the door leaf and the at least one person entering the pivot leaf door is minimized,
wherein at least one sensor unit is configured with which the at least one person is detected and wherein the door actuator has a control unit with which information is received from the sensor unit about presence and/or about spatial dimensions and movements of the at least one person, wherein the pivot movement of the door leaf is performed based on the information recorded by the sensor unit and also based on the correction value.

2 . The method according to claim 1 ,
wherein the control unit has the correction value memory, in which correction values are stored.

3 . The method according to claim 2 ,
wherein the correction values are stored cumulatively in the correction value memory.

4 . The method according to claim 1 ,
wherein the interaction between the door leaf and the at least one person relates to a deliberate behavior of the at least one person.

5 . The method according to claim 1 ,
wherein the correction value for the pivot movement of the door leaf is determined based on the interaction with a number of people in connection with the time of day and/or with the day of the week.

6 . The method according to claim 1 ,
wherein the correction value for the pivot movement of the door leaf is determined based on the interaction with the at least one person in conjunction with a recorded approach speed and/or with a recorded size of the at least one person.

7 . The method according to claim 1 ,
wherein the interactions between the door leaf and a number of people will generate a matrix, a table or a list over a time frame, in which the correction values are stored, in particular in the correction value memory.

8 . A door actuator for carrying out a method according to claim 1 .

9 . The door actuator according to claim 8 ,
wherein a control unit is provided with the correction value memory.

10 . The door actuator according to claim 9 ,
wherein a drive unit is provided which is at least indirectly coupled to the door leaf and wherein the drive unit is designed with a sensor configured for detecting an interaction between the door leaf and a person.
