Definitions
- the invention relates to a method and a device for detecting a pinching situation when adjusting a driven component with the aid of a mechanical adjustment system comprising an electric motor, wherein a force (F act ) related to the force acting on the driven component is changed to a reference value (F Re f) related threshold (F ⁇ h ) is compared.
- Adjustment systems or adjusting devices are used, for example, in motor vehicles to adjust windows or sunroofs as driven components.
- Other applications are, for example, those for the actuation of electrical tailgates or sliding doors, so that, for the sake of simplicity, driven components, if necessary without loss of generality, are used hereinafter
- Sunroofs reference is made.
- an object such as a hand or a head of a person
- This pinch detection is based on a calculated closing force, which is calculated, for example, from the rotational speed and the voltage and / or the current of the electric motor provided for the drive.
- This closing force changes when an object is trapped.
- This closing force change ie a relatively sudden increase in the force beyond a predetermined threshold, serves to decide on a pinching situation.
- a change in the closing force can also occur if there is no pinching situation, namely due to changed conditions during the adjusting movement, such as due to temperature changes and concomitant changes in frictional forces, especially in seals, but also due to contamination in the adjustment and the like. more.
- the distance of the times is chosen so that the system is tuned to the stiffness of the objects to be detected as well as possible.
- the difference formation described eliminates static influences; The disadvantage here, however, is that on the one hand there is a great need for buffer memory space for the past comparison values, and on the other hand, only a limited section from the past is used for pinch detection and thus more remote Information can not be availed (can).
- a reference value is specified as the basis for comparison, in order then to be able to detect a pinching situation by comparing the current force value with the reference value or with a threshold value fixed thereon.
- the reference value is set when the engine starts and is a constant value for previous anti-jamming systems. If necessary, foreseeable reference changes that are stored as characteristics are taken into account, cf. for example DE 10 2007 050173 B3 or DE 19633941 A1. As stated above, due to changed conditions, the real force curve can then diverge from the expected force curve, and even a jamming can occur, even though no object is clamped. Also increased clamping forces would be possible, which could possibly lead to the violation of legal requirements.
- the inventive method of the type mentioned above is characterized in that the reference value, and thus the threshold value is continuously adjusted in the sense of a force trace at the depending on the mechanical system in the adjustment movement changing force value.
- the device according to the invention contains computer means which are set up to carry out an adjustment method according to the invention.
- the present method is thus based on the idea of compensating for the slow deviation of the current force values from the expected forces by performing a "force tracing" of the reference force. Accordingly, the differential force, beyond which the actual force is recognized as being jammed, is also tracked in parallel so as to eliminate the changes in the force curve in the mechanical system, for example because of a stiff mechanism, as a possible reason for pinching detection.
- the force changes which are usually steeper, which are due to clamping operations, or jamming of an object, are excluded from the force tracing described or, if appropriate, such changes in force are only slightly included in the approximation To be able to reliably detect pinching processes.
- this exclusion of force increases resulting in clamping could be based on the fact that the rate of increase of the force curve during clamping is significantly higher than that of mechanical system fluctuations, so that over a certain short period, averaged slew rates are used in force tracking could.
- a much simpler solution can be found here if the ongoing alignment of the reference value (and hence the threshold value) is limited in order to exclude - stronger - changes due to clamping. Due to this limitation of the force tracking, pinching operations are only insignificantly damped, in contrast to the fluctuations in the force curve due to changed conditions in the mechanics. The limitation is expediently made in such a way that mechanical fluctuations are just compensated. This can be done by providing correspondingly small (maximum) limit values.
- F Ref (s + ⁇ s) F Ref (s) - min [(F Ref (s) - F act (s)), F Limit ], where s + ⁇ s is the position and position following s F limit a predetermined limit as a tracking limit.
- the present method can be further advantageously combined with the circumstance that mechanical characteristic diagrams are usually stored in a memory for a respective mechanical adjustment system.
- the reference force initially follows a characteristic curve profile resulting from the characteristic diagrams, and an adaptation to the changing actual force is additionally provided in the sense of the force tracing described above.
- the force tracking threshold may be constant, but this is not necessarily so.
- different force values can occur, such as immediately after starting the engine, in which case relatively high forces occur or are required for adjusting the component in this phase.
- the limit is not constant, but variable;
- the limit value may be a limit value dependent on the position of the driven component, that is to say on the adjustment path.
- the limit is then successively reduced until a constant low value for the phase of smooth running of the engine is achieved.
- a constant low value for the phase of smooth running of the engine For example, an exponentially decreasing limit can be provided in this context.
- Another possibility for a changed limit value during an adjustment movement can result from the fact that in the adjustment system - known - mechanical problem areas are present, such as in the case of a sunroof with a wind deflector, which in certain situations, ie in certain positions of the sliding roof, also temperature-dependent relevant disturbances, ie comparatively higher force increases, can lead. Even in these position ranges from the outset, an increased limit can be provided to thereby compensate for the above-mentioned disorders.
- a further advantageous possibility of the present procedure is that by providing a variable curve of the limit value also voltage fluctuations, such
- an additive limit can be contained in an overall limit value, which changes as a function of such voltage fluctuations, resulting, for example, in a value of this term which increases quadratically with the magnitude of the voltage fluctuation.
- stored characteristic curves which take account of foreseeable reference changes-as known per se-can be used according to an advantageous embodiment of the invention in order to carry out the reference value adaptation particularly efficiently; Accordingly, it is advantageous if, in the case of the adjustment of the reference value (F Ref ), a reference value profile based on stored characteristic data is assumed. It is also advantageous for a motor starting process to be temporarily comparatively high
- Limit value is used to quickly adjust the reference value to the strong force changes during startup. It is favorable for a simple calculation, if one of a With a comparatively high initial value, an exponentially decreasing limit value is used.
- the present force tracking approach may result in a portion of the pinching process being compensated and thus lost for the detection of pinching.
- a rather low limit is introduced.
- only relatively stiff objects with a high force increase in the differential force can be selectively detected with regard to pinching.
- Such hard objects are, for example, the 65 N / mm spring rates required by US FMVSS 118 S5, and if a high limit is set, such stiff or hard objects will be well recognized since all other "noise" is heavily filtered It is now possible to perform its own additional pinch detection for such special objects, using a correspondingly high limit, which is specifically tuned to such hard objects, and this can be further supplemented by, for example, various specific ones Object hardnesses (in particular the legally required object hardnesses 10 N / mm, 20 N / mm and 65 N / mm) are each provided with their own terminal detection, with their own limit value the different object hardnesses can thus be constant g in a simple manner which increases the robustness of the system.
- Object hardnesses in particular the legally required object hardnesses 10 N / mm, 20 N / mm and 65 N / mm
- the different object hardnesses can thus be constant g in a simple manner which increases the robustness of the system.
- a limit set to the stiffness of pinching objects is set for the limitation, the limit being higher is, the higher the stiffness of the pinching object; wherein it is further favorable if at least two force pursuits with different limit values are carried out in parallel with one another in order to carry out adapted adjustments of the reference value to the force values for differently stiff pinching objects.

- Fig. 11 is a diagram comparable to Fig. 10, but now, unlike in Fig. 10, is based on a stored force value, which then shows that when using the last displacement force, which is still stored as a starting value, the matching the startup phase can be accelerated so that the steady state of the algorithm is reached earlier.
- Fig. 1 is a schematic block diagram of an adjusting device 1 with an electric motor 2 for driving a vehicle component not shown otherwise, such as a sunroof, shown, with central computer means 3 (CPU 3) as an integral part of the device 1 are provided to perform a drive, such as a PWM drive, the motor 2 via a PWM switch 4;
- This PWM switch 4 is shown in Fig. 1 only schematically and is realized in practice usually eg with the aid of a field effect transistor (FET).
- FET field effect transistor
- the PWM switch 4 applies according to a by the computer means 3rd predetermined duty ratio, a supply voltage U Bat / on terminals 5, 6 of the device 1, to the motor 2 at.
- the voltage U Mot actually applied to the motor 2 is optionally measured by means of measuring means 7, the corresponding measured values being supplied to the computer means 3.
- a sensor 8 for measuring the rotational movement namely with regard to the detection of position s, speed v or angular velocity ⁇ and / or power of the motor 2 is provided;
- This sensor 8 may be provided in addition to or instead of the measuring means 7 for the formation of a control system, and it may for example be a Hall sensor.
- the output signal (measurement signal) of the sensor 8 is also supplied to the computer means 3.
- the computer means 3 are connected to a memory 9, are stored in the data concerning the mechanical characteristic of the adjusting device 1 and the mechanical system of this adjustment.
- a possible characteristic F (t) is illustrated in FIG.
- measuring means 11 for measuring the supply voltage U Bat are also present, the measured values likewise being supplied to the computer means 3.
- the computer means 3 form in a conventional manner PWM drive means for the motor 2, which are implemented by a PWM module 3A in FIG. 1 in combination with the PWM switch 4.
- an anti-pinch module indicated by a module 3B in the computer means 3, the anti-jamming system, which also includes switching relays 12, 13, in order to reduce the motor speed in the Case of detection of pinching, as known per se, to be able to reverse the motor 2.
- the switching relays 12, 13 are shown in Fig. 1 schematically in one of their normal operating positions, they both change the switching position when reversing the motor 2. In the rest position (not shown), both switching relays 12, 13 assume their upper position according to FIG. they are then both at the terminal 5, as indicated in Fig. 1 at the switching relay 12 with a dashed line.
- the PWM switch 4 is open in the rest position.
- This closing force calculated according to the above relationship becomes the pinching detection in the prior art based on.
- the closing force changes when an object, such as an arm, a hand or a head, from the driven component, such as a vehicle side window or a sliding roof, is trapped.
- the closing force may also change during operation, if the
- FIG. 2 illustrates a diagram in which, for example, a profile of the current force F act , the course of a reference force F Re f and, parallel to the latter, the course of a threshold value, a threshold force F ⁇ h , are illustrated.
- the movement of the driven component for example a sunroof, when closing is shown by the course of the position s, whereby in the normal case this positional course takes place approximately linearly with time.
- a pinching process now begins at position 14, whereby the actual force F act relative to the reference force F Re f increases relatively sharply due to the clamped object until the threshold value F ⁇ h at time t 2 , in of position 15.
- F ⁇ h is decided by the system, that is, by the computer means 3 in Fig. 1, a pinching operation, wherein the motor 2 is stopped and reversed in the sequence, which in connection with the course of the position s in Fig. 2 at time t3 - indicates. Up to the time ti, however, the forces F act and F Re f run uniformly in the example of FIG. 2, ie no mechanical force fluctuations occur.
- This divergence indicates, for example, a mechanic (regional or general), which is meanwhile more difficult to move, and this gradual divergence, this relatively slow deviation of the force F act from the reference force F Ref , is now to be distinguished from a relatively strong increase due to pinching of an object become.
- F Ref (s + ⁇ s) F Ref (s) + min [F act (s) -F Ref (s), F Limit ]
- Fllltllt denotes a limit value to be given for force tracking, ie a "tracking limit.”
- This limit value describes the maximum stiffness of an imaginary object clamped in the mechanical system, which is still fully compensated by the force tracing positive deviations, for F akt (s) ⁇ F Re f. (s)
- the present force tracking can however also be provided in the case of negative deviations, for F akt (s) ⁇ F Re f (s), wherein then:
- F Ref (s + ⁇ s) F Ref (s) - min [F Ref (s) - F act (s), F Limit ]
- the reference value F Ref does not change either.
- this difference is used for compensation as long as added to the previous reference value F Ref (s) or subtracted from it in order to come to the reference value in the next position s + ⁇ s, as long as this difference does not limit the value F LlItllt exceeds. Otherwise, the limit F limit is used for the approximation.
- this limit value F limit is now selected such that the curve according to curve 16 in FIG. 4 results for the adjusted reference value F Re f.
- the limit F limit is comparatively smaller, the reference value, s. F Re f 'in Fig. 4, the course in accordance with the curve 17.
- the limit F limit is comparatively smaller, the reference value, s. F Re f 'in Fig. 4, the course in accordance with the curve 17.
- this is just one example of several possibilities.
- the present method of reference value matching can be combined, for example, with particular advantage with stored mechanical characteristic fields, with reference values corresponding to curve 10 in FIG. 3, in which case a reference value always corresponds as output reference value F Re f in the preceding relationships This curve 10 is used, so no constant reference value.
- the obtained reference value is then not merely by the described
- Force trace based on a constant value formed, but it is the sum of the reference force curve 10 (according to characteristic of mechanics) and the proportion of force tracking according to the above relationships, in mechanical force fluctuations.
- the limit value F LlItllt for force tracking has been assumed to be constant above by way of example. However, this need not necessarily be the case; Reference level adjustment advantageously use a variable limit F limit , with the size of the limit F LlItllt the circumstances of the mechanical system can be taken into account.
- a temporarily high limit value F LlItllt can be provided which, for example, decreases according to an exponential curve with the progression of the time (or of the travel), as can be seen from the diagram according to FIG.
- a high limit F LlItllt is used, so that even strong force fluctuations can be compensated in this starting phase.
- the reference value F Re f corresponds as reliably as possible to the actual force F act , which changes very greatly in this time interval.
- the threshold ie, the tracking limit, is then gradually reduced until the low, eg, constant, steady state value for smooth engine running shown in FIG. 5 in the right part of the diagram is reached.
- temporarily increased limit values F.sub.LItllt may prove to be advantageous, for example if, depending on the position, eg if a sunroof is in a specific position close to the closed state and there is a wind deflector, a mechanically non-reproducible behavior (eg temperature-dependent) is given is. Accordingly, the tracking limit can be increased in this area in a position-dependent manner in order to better compensate for such disturbances.
- FIG. 6 illustrates that the criterion for terminal detection is not the absolute value of the closing force, but the difference .DELTA.F between the closing force at a certain point in time and the closing force at a defined point in time the past.
- the distance of these times is chosen so that the stiffness of the objects to be recognized is taken into account.
- the subtraction eliminates static influences.
- a disadvantage of this solution is that a large amount of buffer space is required for the past comparison values, and that only a limited section from the past is used for pinch detection, but past information can not be used.
- FIGS. 7 and 8 Force curves for the current force F act and for the unadjusted reference force F Re f (FIG. 7) or for the adjusted reference F ref (FIG. 8) are now illustrated in FIGS. 7 and 8 respectively in the upper part.
- the adjusted reference curve results in the manner described above, cf. 4. It can be seen that there is a problem location in the mechanical system in the area around the time "200 ms.” According to FIG. 7, in this area the triggering threshold F ⁇ h is briefly increased in advance, this increase being shown in FIG 7 is denoted by 18.
- the curve 19 indicates the differential force obtained without force tracking as described above, and it can be seen from the graph of FIG Approach according to the prior art would disadvantageously lead to a Fehlreversieren.
- variable (increased) limit values may also prove expedient for the case of voltage fluctuations of the on-board voltage U Bat (see FIG.
- a proportion in the above relationships which is proportional to the magnitude of the voltage fluctuation, may be added to the specified limit F Limit .
- This term attributable to the voltage fluctuation can be determined, for example, by subtracting from the unfiltered voltage U Bat (t) a voltage value U L p (t) after low-pass filtering. The following relationship therefore results for this modified limit value F LlItllt ':
- k is a system parameter that indicates how much the limit value is to be increased as a function of the magnitude of the voltage current.
- This system parameter k can be determined empirically in advance.
- FIG. 9 shows, by way of example, a corresponding progression of F Limit (or F ' Limit ) in conjunction with an abruptly rising battery voltage U Bat and a low-pass filtered voltage U L p.
- a parameter k as a function of the voltage U, that is to say k (U), whereby a non-linear relationship between k and U is possible.
- a quadratic relationship between k and U is given, ie that the parameter k increases quadratically with the height of the voltage jump.
- the battery voltage increases at the end of a cranking pulse, and with such a voltage increase, a force curve can be produced, which corresponds to that of FIG. 7 and 8.
- a force curve can be produced, which corresponds to that of FIG. 7 and 8.
- a further advantageous variant results in that when the last displacement movement is only a short time ago, the displacement force remains relatively constant. For this special case of a brief interruption, the last displacement force can then be used as the starting value for the reference force F Ref , whereby the starting value of the force tracing can be better adapted and the starting phase can be shortened so that the stationary state of the algorithm is reached earlier.
- FIG. 10 shows that after a switch-off of the displacement movement, the force tracing is started practically at zero, so that it requires a relatively long period of time until the reference value F Re f is brought to the current force F act .
- the value of the displacement force given when the engine is turned off is stored and used as the starting force tracking value for the reference value F Ref . a more rapid approximation of the reference value to the actual force F act can be achieved.
- the invention can of course also with adjusting devices 1 without PWM control (as in Fig. 1 shown), with other controls, in particular relay drives, are known in the art.
