Definitions

  • Windscreen wiper device for wiping a window and method for operating such a window
  • the invention relates to a windshield wiper device according to the type of the independent claims.
  • the motor drives the wiper blades via the linkage and the wiper arms.
  • the squeegees generate a frictional force depending on the contact force of the squeegee on the disc and the coefficient of friction on the disc.
  • the motor continues to introduce its torque into the system via wiper arms and linkage.
  • the components, in particular the linkage, wiper arm and wiper blade are thereby elastically preloaded.
  • Wiper blade is reached along the target trajectory
  • Vibration compensation controller can, for example, also be capable of learning, can be designed as a neural network and as fuzzy logic, as a result of which adaptive properties are achieved.
  • a position signal is used as a controlled variable for the active
  • the position sensor can also be attached to the wiper linkage itself. It is also possible to attach an acceleration sensor to the wiper arm or wiper linkage, which is connected to the control device. In this way, an even more precise regulation can be achieved.
  • a control device with a frequency selection stage which is designed in such a way that it is permeable to the frequencies typical of the rattling of the wiper blade, has proven to be a further advantage, in particular if it is designed as a bandpass filter. In this way, uncharacteristic frequencies can be filtered out for the disturbance to be compensated.
  • bandpasses are available as inexpensive mass-produced goods of the appropriate quality.
  • phase shifting element Another advantage is the use of a phase shift element. It can be used to precisely set the phase of the manipulated variable of the active control level.
  • the phase shifting element is advantageously designed as a low-pass filter, since these are also available as inexpensive mass-produced goods of the appropriate quality.
  • Figure 1 shows a windshield wiper device according to the invention in a schematic representation
  • Figure 2 is a diagram of the speed ⁇ of the wiper motor over time t.
  • Fig. 1 shows a windshield wiper device for performing the method according to the invention according to claim 1 in a schematic representation.
  • a wiper blade 10 moves on a disk 12 and is driven by a wiper motor 14 via a motor shaft 15.
  • a position sensor 16 is located in the wiper motor 14 itself, for example a Hall sensor or a resistive sensor, which emits signals about the position of the motor shaft 15.
  • These position signals 17 are recorded by a control device 18.
  • the chatter compensation stage 22 has a differentiating unit 24, a frequency selection stage 26 and a phase shift element 28.
  • the motor speed ⁇ is plotted against the time t for three wiping periods, in the case in which the wiper blade 10 "rattles" over the window.
  • the signal has a large oscillation of the amplitude A, which is caused by the back and forth movement , between the reversal of the wiper blade 10 on the window 12.
  • the amplitude A is controlled by the position controller 20.
  • the current I of the wiper motor 14 In order to minimize the duration of the stick, that is to say the time interval in which the squeegee 11 adheres to the window 12, the current I of the wiper motor 14 must be briefly increased further.
  • the wiper blade 10 is accelerated by the released elastic energy. This increases the engine speed n.
  • the position signal of the wiper motor 14 is passed to the chatter compensation stage 22, which serves as a component which compensates for disturbances.
  • the chatter compensation stage 22 serves as a component which compensates for disturbances.
  • one or more time derivatives of the signal are carried out in a differentiating unit 24; in principle this is irrelevant for the function of the active control.
  • the signal is then introduced into a frequency selection stage 26, for example a bandpass filter, which passes the frequencies typical for rattling, and in particular filters out the amplitude A resulting from the back and forth between the reversal positions of the wiper blade 10.
  • the following phase shifter 28 now fits the phase of the filtered signal according to the above Compensation characteristic and acts on the input current I of the wiper motor 14 accordingly.
  • the input current I of the wiper motor 14 is acted upon as the manipulated variable of the position controller 20 with the manipulated variable of the chatter compensation stage 22.
  • chatter behavior can also be recognized and compensated for on the basis of the current I consumed by the wiper motor 14. This has a similar behavior to that seen in FIG. 2.
  • the chatter compensation stage 22 can, for example, also be designed as an active control stage.
  • Such a compensation controller as a control stage is described for example in DE 197 40 153 AI. This active control level can detect and compensate for periodic faults.
