Description
Prior art
The present invention relates to a kind of glass for vehicle window wiper device as type as described in the independent claims.
People are known for a long time, and the glass for vehicle window wiper device is especially for easily causing chatter than the drying cart wind glass.This chatter degree of Wiper rubber is relevant with many mechanical factors.These factors come from has different elasticity (Wiper blades, Wiper arm, joystick) but oscillation system and its quality and external force, as with rubber and glass for vehicle window between friction coefficient and the friction force on the relevant glass for vehicle window of Wiper blade contact pressure and the driving power of wiper motor.Motor drives Wiper blade by joystick and Wiper arm.Wiper rubber produces and the contact pressure of Wiper rubber on the glass for vehicle window friction force relevant with friction coefficient.
Under the mode of operation of regulation, for example when glass for vehicle window is relatively dry, can cause so-called "blind"effect.At this, friction force produces resistance and reduces its speed on glass for vehicle window Wiper rubber in " attachment stage ".
During this period, motor continues rotating torque is imported in the system by Wiper arm and joystick.These members, especially joystick, Wiper arm and Wiper blade are thus by flexibly tensioning.
When the drive torque of Wiper blade during greater than friction moment, the static friction of Wiper rubber is eliminated, thereby rubber breaks away from adhering on glass for vehicle window.At coast period, the member that flexibly is tensioned discharges it by the tensioning energy stored, and Wiper blade is fiercely quickened.
By carrying out the transition to cliding friction from static friction, friction coefficient reduces, and therefore, the system that is made up of Wiper arm and Wiper blade reaches original actuating speed in advance, and this will cause excessive swing.When elastic energy was depleted, Wiper blade was braked once more, and was attached to again on the glass for vehicle window, and the circulation of creeping restarts.
Up to the present, this chatter phenomenon can only be as US4 for example, 793,020 announce like that, attempt to be limited by the ideal design of mechanical part.
Advantage of the present invention
In the inventive method according to claim 1 feature, advantageous particularly is can be proofreaied and correct fast and accurately by the interference that the external force effect causes, so prevented that especially effectively Wiper blade is at chatter on glass.
Draw the favourable expansion and the improvement of the method that provides in independent claims by the measure that proposes in the dependent claims.
If disturb is that repeat the short time and interference chattering type, as the chatter of Wiper blade on glass for vehicle window is exactly this situation, then disturb and to be resisted in advance, at this, control wiper motor with the vibration interference anti-phasely, be proved to be very favorable, because can realize Wiper blade evenly moving like this along desired trajectory.
If the governing stage (Regelungsstufe) by initiatively (aktiv), for example utilize a vibration compensation regulating control to implement this method, then time length interference longer, different cycles can be well controlled.But this vibration compensation controller can be arranged to for example self study, neural network and fuzzy logic type, realize adaptive characteristic thus.
Therefore, the characteristic parameter of wiper motor, especially electric current I are used as the adjusting parameter of active adjustment level, have saved the essentiality that other sensor is set in wiper motor, have reduced cost and wearing and tearing thus.
If adopt the adjusting parameter of position signal, then be issued to maximum accuracy not increasing condition of cost, because modern wiper motor has had position transduser usually as the actv. governing stage.Position transduser also can be installed in the Windshield Wiper joystick originally on one's body.
Also an acceleration pick-up that links to each other with control setup can be installed on Wiper arm or Windshield Wiper joystick.By this way, can realize more accurate control.
Have frequency and select the control setup of level to be proved to be favourable, especially when it constitutes as bandpass filter.Frequency selects level to be constructed like this, and promptly its permission is that the representative type frequency is passed through for the Wiper blade chatter.Like this, the frequency that does not characterize the feature of interference to be compensated is filtered off.In addition, bandpass filter can be used as the commodity acquisition with low cost with respective quality.
Another advantage is to adopt phase-shifting element.Whereby, the phase place of the adjusting parameter of actv. governing stage can accurately be regulated.This phase-shifting element preferably constitutes as low-pass filter, uses because it can be used as the low commodity of cost with respective quality equally.
In addition advantageously, above-mentioned all parts, as phase-shifting element, frequency selects level and differentiation element to be realized by software in control setup.
Accompanying drawing
Shown in the figure be:
Fig. 1 shows the scheme drawing of wiper device of the present invention,
Fig. 2 shows the speed omega of wiper motor and the relation curve of time t.
The embodiment explanation
Fig. 1 shows the wiper device that is used to implement the described the inventive method of claim 1 in schematic form.Wiper blade 10 moves on a glass 12 and is driven by a motor shaft 15 by a wiper motor 14.Itself have a position transduser 16 in the wiper motor 14, Hall element or resistance (resistiver) sensor for example, it provides the position signal about motor shaft 15.Position signal 17 is received by a control setup 18.This device comprises a position control 20 and one for example as the chatter compensated stage 22 of active adjustment level.Chatter compensated stage 22 has 24, one frequencies of a differentiation element and selects 26 and phase-shifting elements 28 of level.
In Fig. 2, drawn motor speed ω and scraped the curve of water in the cycle at three with respect to time t, at Wiper blade 10 under the situation of " chatter " on glass.Signal has the big vibration of amplitude A, and it comes from the crank motion of Wiper blade 10 between the swivel point on the glass 12.Amplitude A is by position control 20 controls.
In addition, this curve has the harmonic wave of higher frequency and littler amplitude, and it is that joystick that chatter by Wiper blade causes and by wiper device passes in the wiper motor 14.
When Wiper rubber adhered to, friction moment rose, and therefore, revolution and motor speed descend.The current draw of motor rises in " adhering to " stage thus.
The time length that adheres to for reduction, i.e. the time gap that on glass 12, adheres to of Wiper rubber 11, the electric current I of wiper motor 14 must further be increased in short time.
When Wiper rubber 11 in " sliding " stage of back when shaking off glass for vehicle window 12, Wiper blade 10 is accelerated by the elastic energy that discharges.Therefore, motor revolution n increases.
This moment, the electric current I of motor must reduce, so that reduce the toning of system, promptly system must be braked by wiper motor 14.
For this reason, the position signal of wiper motor 14 is transferred on the chatter compensated stage 22 as the parts of compensate for disturbances.For improving signal quality, in a differentiation element 24, signal is carried out the one or many time derivative; But, in principle, this function to active adjustment does not have significance.Next, signal is admitted to frequency and selects in the level 26, bandpass filter for example, and it allows the representative type frequency for chatter to pass through, and especially leaches by the amplitude A of back and forth scraping water and being produced between the swivel point of Wiper blade 10.The phase-shifting element 28 of back then mates corresponding to above-mentioned compensation characteristic the phase place that leaches signal now and correspondingly the received current I of wiper motor 14 is applied effect.
As a result of, the received current I of wiper motor 14 is applied in the adjusting parameter of chatter compensated stage 22 as the adjusting parameter of position control 20.
When not having position signal available, the chatter characteristic also can be known and compensated according to wiper motor consumed current I.It has the similar characteristic that can find out with Fig. 2.
Chatter compensated stage 22 for example can be configured to the actv. governing stage.Such compensated regulator for example is described at DE197 40 153 A1 as governing stage.But this actv. governing stage recognition cycle is disturbed and to its compensation.
In addition, can on the Windshield Wiper joystick acceleration pick-up be installed, as formerly disclosed DE198 45 674 never as can be known, its signal is delivered in the chatter compensated stage 22 and is used.By this way, motor is controlled in real time for overcoming its creeping phenomenon.
