  • the present invention relates to a method for the automated control of an electrically operated window in a motor vehicle. Furthermore, the invention relates to a device and a computer program, each of which is configured to carry out the method.
  • Such windows are installed in particular in newer motor vehicles, in which a respective window pane is moved in the window frame of the window by an electric motor.
  • the anti-trap function is intended to prevent an object from being trapped between the window pane and the associated window frame while the window is being closed by the electric motor.
  • One way to determine whether there is an object between the window pane and the frame is to indirectly measure the force used to move the window pane using the electric motor. For the closing process, a continuous and essentially constant force can be transmitted to the window pane by the electric motor. A current required for this can be measured.
  • the force which the window pane or the electric motor must overcome to move the window pane in the closing direction can increase. This would also increase the current required by the electric motor to move the window pane. By continuously measuring this current, it can be determined whether the current used by the electric motor remains essentially constant or is increasing. An increase in the current used can indicate that an object has become trapped between the window pane and the window frame. By controlling the electric motor, the closing process can be interrupted or reversed when the current increases, i.e. the window is opened again.
  • This type of force measurement is technically complex and can, in particular, be used against external influences such as a temperature fluctuation or very hot or very cold temperatures, prone to failure.
  • external influences such as a temperature fluctuation or very hot or very cold temperatures, prone to failure.
  • this can mean that seals arranged in the window frame cause greater mechanical resistance to movement of the window pane along the seals, which means that the electric motor has to consume more power.
  • This can lead to incorrect activation of the anti-trap function, which stops or reverses the closing process of the window, even though there is no object between the window pane and the window frame.
  • the object of the present invention is to propose a method for controlling an electrically operated window with a reliable anti-trap function.
  • a first aspect of the invention relates to a method for the automated control of an electrically operated window in a motor vehicle, the method comprising: (i) determining, using a sensor arranged on the motor vehicle, whether during a driven movement process of the window in which a window pane is moved within an associated window frame of the window, a physical object is present in a gap between the window pane and the window frame of the window, wherein (ii) the sensor is based on a wireless measuring principle, so that when detecting the presence or absence wireless, in particular electromagnetic and/or acoustic, signals characterizing the object in the intermediate space are detected by the sensor; and (iii) controlling the movement process, in particular an opening or closing process, of the window depending on the determined presence or absence of the object in the intermediate space.
  • a condition A or B is satisfied by one of the following conditions: A is true (or present) and B is false (or absent), A is false (or absent) and B is true (or present), and both A and B are true (or present).
  • the term "configured” or “set up” to fulfill a specific function (and respective modifications thereof) is to be understood within the meaning of the invention that the corresponding device is already in a configuration or setting in which it can perform the function or it is at least adjustable - i.e. configurable - in such a way that it can carry out the function after the appropriate setting.
  • the configuration can take place, for example, via a corresponding setting of parameters of a process flow or of switches or the like for activating or deactivating functionalities or settings.
  • the device can have a plurality of predetermined configurations or operating modes, so that the configuration can be carried out by selecting one of these configurations or operating modes.
  • the method according to the first aspect makes it possible for the movement process of the window to be controlled depending on the determined presence or absence of the object in the intermediate space using a sensor which is based on a wireless measuring principle.
  • a sensor which is based on a wireless measuring principle.
  • a Cable connection in the area of the window in particular a cable connection between an electric drive for the movement of the window pane and an associated evaluation logic can be dispensed with.
  • current measurement data from an electric drive for the window pane can be evaluated in such an evaluation logic and, based thereon, it can be determined whether an object is located between the window pane and the window frame.
  • a seal arranged in the window frame, in which the window pane is moved, can exhibit temperature-dependent friction with respect to the moving window pane.
  • controlling comprises pausing the process of moving the window upon a detected presence of the object in the gap. It can thereby be ensured that the object is not jammed in the intermediate space between the window pane and the window frame.
  • the method further comprises, when determining the presence of the object in the gap, determining an object type of the object depending on the detected signals and by comparing the signals or measurement data derived therefrom with predetermined reference data on known objects; the movement process also being controlled as a function of the specific object type.
  • a comparison with a known object can be used to determine more reliably whether an object is located between the window pane and the window frame. Because this method step can be used not only to determine whether an object is located between the window pane and the window frame, but also which object.
  • the determination further includes the signals being detected multiple times by the sensor within a measurement period during the movement process, and the determination of the presence or absence of the object based on a comparison of at least two different points in time within the measurement period signals detected by the sensor. This means that the presence or absence of the object can be determined more reliably, since signals are detected at least at two different points in time and are compared with one another.
  • controlling the movement process of the window comprises automatically causing a direction reversal of the movement of the window in the event that the presence of the object in the gap is detected.
  • the actual movement of the window may result in the window closing. If the direction is reversed, the window is then opened. This can be advantageous in order to prevent the object from becoming trapped between the window pane and the window frame. It is also conceivable that an object that has already been jammed is freed again by the reversal of direction. In another case, the actual movement of the window may result in the window opening. If the direction changes, the window is then closed.
  • the method also includes sensory detection of a vehicle train status of the motor vehicle or an identity or behavior of one or more vehicle occupants, and outputting the corresponding sensor data, with a predetermined movement process of the window being automatically initiated if the sensor data meets a predetermined criterion fulfill.
  • a movement process of the window is automatically initiated when the sensor data meet a predetermined criterion.
  • the sensing determines whether a seat in the vehicle is occupied by a person, the sensing determines biometrics of that person, and manually controls a window disposed adjacent the seat , depending on the biometric data.

  • the manual control of the window can be automatically prevented. This can increase the safety of the child in the vehicle.
