Definitions

  • Locking devices with locking parts which are moved by means of a motor are widely used - for example for the electrical actuation of side windows, sunroofs or convertible top controls of motor vehicles, for the electrical actuation of gate locking systems for roller doors or garage doors or for the electrical actuation of elevator doors.
  • a motor by means of motor drives
  • Locking devices with locking parts which are moved by means of a motor are widely used - for example for the electrical actuation of side windows, sunroofs or convertible top controls of motor vehicles, for the electrical actuation of gate locking systems for roller doors or garage doors or for the electrical actuation of elevator doors.
  • either the opening to be closed can be monitored itself (for example by means of optical detectors) or the closing process can be assessed with regard to potentially existing obstacles - for example by determining and evaluating the clamping force that arises during a trapping event (since its direct determination is necessary because of this Sensors is quite expensive, it is usually determined indirectly by recording at least one parameter characteristic of the load on the motor drive).
  • the invention has for its object to provide a method that ensures simple and effective protection against jamming of locking devices with at least one motor-driven locking part. This object is achieved according to the invention by the features in the characterizing part of claims 1 and 2.
  • the described method enables the detection of pinching events when closing devices with at least a motor-driven closing part by the Closing device occurring pressure forces either as absolute pressure values or be analyzed as pressure change values.
  • a pressure measuring device either at the end of the closing path in the closing opening itself (i.e. in the closing path of the Locking part integrated) or at the end of the closing section in the immediate vicinity Attached near the opening to be closed (i.e. in the border of the closing path of the locking part integrated) - e.g.
  • the pressure measuring device in the side window of a motor vehicle either in the gap between the two sealing lips of the window gasket of the side window pane attached (in this case, the sealing lips must be up to Can give way) or at least one sealing lip of the Window seal of the side window pane.
  • the pressure measuring device is preferably in the entire range closing opening or in the immediate vicinity along the whole closing opening attached.
  • the (current) pressure measured values of the pressure acting at the end of the closing path in the opening to be closed or in the immediate vicinity of the opening to be closed are continuously determined by the pressure measuring device and evaluated by comparison with a pressure limit value (triggering threshold value), in particular with regard to pressure changes that occur. If, when the pressure measuring device is attached to the opening to be closed, the current pressure measured value exceeds a predetermined pressure limit value (triggering threshold value), there is either the end of a "normal" closing process or a pinching event; the motor drive is then switched off.
  • a pressure limit value triggering threshold value
  • a pressure measuring device for example. a pressure sensor can be used, which can also sense very low absolute pressure values or very low pressure change values.
  • Such a fiber optic load sensor can sense pressure changes (of the surface pressure) over its entire length and can therefore be easily installed in the opening to be closed or in the immediate vicinity of the opening to be closed (in particular it can be along the entire length of the opening to be closed or in in the immediate vicinity along the entire opening to be closed).
  • pinching events can be reliably detected with the presented method in a simple manner and with inexpensive implementation, as a result of which the method ensures effective pinching protection and thus a high level of safety.
  • a fiber optic exposure sensor 4 is integrated into at least one of the sealing lips 3 of the window seal of the side window pane 2 of the motor vehicle 1; this fiber-optic loading sensor 4 continuously measures the pressure measurements on the edges of the opening 5 to be closed by the side window pane 2 and sets these pressure measurements, for example.
  • a control unit for further processing and evaluation for example, this control unit can be designed as a separate control unit or can be part of a control unit already present in motor vehicle 1).
  • a pressure limit value is defined as a trigger threshold value, for example can be stored in the control unit; If a (possibly further processed and evaluated) measured value of the fiber-optic load sensor 4 exceeds the pressure limit value, the presence of a pinching event is assumed and the window regulator drive is briefly reversed (briefly opening the side window pane 2) and then the window regulator drive is switched off.
  • a (possibly further processed and evaluated) measured value of the fiber-optic load sensor 4 exceeds the pressure limit value, the presence of a pinching event is assumed and the window regulator drive is briefly reversed (briefly opening the side window pane 2) and then the window regulator drive is switched off.
  • an approximately 2 m long fiber-optic load sensor 4 is integrated into the two sealing lips 3 of the window seal of the side window pane 2 of the motor vehicle 1, which can sense pressure measurements or pressure changes of approximately 1 N / m 2 over its entire length; the pressure limit as a measure of a potential pinching event is e.g. specified at a pressure of 1.5 N /
