  • Publication number: 20250137312
    Abstract: A method determines a door opening request based on a pressure actuation against a door of a household appliance. A plunger is driven by an electric machine via a transmission. An electrical voltage is applied to a stator winding which is electrically coupled to a control unit at least during temporary support of the plunger head against a door inner face. When the door is in the closed state a force is applied to the plunger and by a sensor facility a stator winding-side induced voltage is detected, which has a voltage pulse depending on the pressure actuation. An amplitude of the voltage pulse is compared in a first comparison with a voltage comparison value and a temporal extent of the voltage pulse is compared in a second comparison with a time comparison value. The door opening request is determined depending on comparison results of the first and second comparison.

  • Publication number: 20230349630
    Abstract: A method determines an actuation of a door of a household appliance by a user. The door closes an access opening of a body of the appliance to an interior space by virtue of an elastic seal that is arranged on the door inner side and braces circumferentially against a region of an edge of the access opening. A plunger is moved by a drive unit until a plunger head braces against the door inner side. The plunger is influenced into an opening direction of the door by the drive unit using a bracing force that is smaller than a force for opening the door. An arbitrary stroke of the plunger is detected by a sensor and a sensor signal is allocated to the detected stroke. The sensor signal is compared with a comparison value and the actuation by the user is determined in dependence upon the comparison.

  • Patent number: 7675433
    Abstract: A device and a method determine sensor positions of sensor units of a driver assistance system, especially a parking aid system of a vehicle. The sensor units each have a plurality of terminals of different identification positions. A data bus is connected for an exchange of data with a central control and evaluation unit in this case with one or more terminals of the sensor unit according to a specific connection scheme, which is different for each of the sensor units, in order to provide an identity code for the sensor position of a sensor unit in this way.

  • Patent number: 6804562
    Abstract: The invention relates to a method for overload-free driving of an actuator, in which an activation counter is incremented or decremented each time an activation request signal occurs, in which, depending on each occurrence of an activation request signal, a drive signal for the actuator is generated if the counter reading of the activation counter is less than or greater than a predetermined maximum or minimum counter reading, in which the counter reading is in each case decremented or incremented if the time since the last generation of a drive signal or since the deactivation of the drive signal is greater than or equal to a predetermined or predeterminable interval time or if the time since the last decrementing of the activation counter is greater than or equal to the interval time.
