Definitions

  • the invention relates to a method for operating an electromechanical adjusting device, with an actuating part, which is driven by a motor, which controls a control device, depending on a manual specification on an operating element of the control device, between a first end position and a second end position is adjustable, the Control device is set up to recognize from an inferred encoder signals of a donor means positionally accurate blocking an adjustment.
  • the anti-pinch protection can only be effective if the position assumed by the control device of the setting part coincides with the actual position. To ensure this is an initialization of the actuator required, which can be performed for the first time in the manufacture of the drive but also during operation, and in which a reference position is determined.
  • a reference position is determined.
  • the window pane is moved upwards, against a rubber seal in the door frame.
  • the blocking position in the closed position of the disc is considered as a reference point ("absolutely zero") for all subsequent positioning movements of the disc.
  • Such an error could be detected during the manufacturing process as part of a quality assurance, for example by visually checking whether the window pane is actually in an open or closed position. If this is not the case, the initialization must be carried out again. This is associated with a corresponding effort. However, if this error occurs during normal use during operation, the customer must visit a specialist workshop, which is costly.
  • the invention is based essentially on the idea of not only defining a reference position but also of checking its validity. In other words, not only is a reference position learned, but what is learned is also checked for accuracy, or in one word said, validated. It is only on the basis of this test result that it is decided whether automatic closing is allowed. This can do that
  • this test is carried out on the basis of a manually controlled setting process, the disc in an end position, the open position of a
  • a preferred embodiment of the invention may be characterized in that it is decided only after reaching the second end position depending on the test result, whether the previously detected reference position is retained or discarded. As a result, the validity is correctly determined even in a mechanical boundary area and a secure closing is ensured.
  • the invention can be realized if existing hardware can be used, i. if e.g. used as donor means common position sensor and be used to detect a mechanical blockage, as well as for position detection, the same position signals of this position encoder.
  • the reference value may be expedient for the reference value, together with additional information characterizing the validity, to be stored in a memory cell of the memory device.
  • the test program can be easily implemented as an algorithm on a microcontroller. It can be of very particular advantage if the validity of the position is checked both during initial initialization in production and during reinitialization during operation of a motor vehicle. Depending on the application, it may be of particular advantage if the reinitialization either at regular intervals, or when, in an error case, an initialization loss is detected is performed.
  • Figure 1 is a schematic representation of an electromechanical adjusting device with reference to the invention will be explained.
  • FIG. 1 shows a schematic representation of a power-operated window lens lifter, as it is commonly used today in motor vehicles. The inventive method for operating this
  • the electromechanical adjusting device is indicated in Figure 1 in its entirety by the reference numeral 22. It consists essentially of a control part 1, which is here a motor vehicle window glass 1, which is adjustable by means of the driving force of a motor 2 within an adjustment path 3 (stroke).
  • the engine 2 is through gear 14 and a cable 13th coupled with the window pane 1.
  • the motor 2 is connected to a control line 15 to a control device 4, a microcontroller.
  • a position sensor 5 is coupled to the drive train, the encoder signals via a line 17 of the
  • Control device 4 are supplied.
  • the control device 4 comprises the microcontroller 23 with a memory device 19 and is connected to a power supply 16.
  • the program in the microcontroller is u. A. arranged to determine by evaluating the encoder signals blocking when adjusting the window 1 and contains the test program, which is explained in more detail below.
  • an operating element 6 is provided on the control device 4.
  • This control can be a simple push-button.
  • a setting process can be carried out in full operation of the adjusting device 22 in a known manner, either manually or automatically: in manual mode, the window is moved as long as long as you operate the control element 6 manually; in the automatic operating mode, the adjusting movement runs automatically as soon as a predetermined operating interval of the operating element 6 is exceeded.
  • the window pane 1 along the adjustment path 3 is adjustable; the maximum possible stroke of the adjusting movement is predetermined by a first (upper) end position 21 and a second (lower) end position 20.
  • the first end position 21 is limited by a mechanical stop 11, the second end position 20 by a mechanical stop 10. In normal operation, the lower stop 10 is not started.
  • the sketched in Figure 1 current position of the Window pane between these two end positions 20 and 21 is indicated by a pointer 12 which corresponds to the upper edge of the pane 1.
  • the maximum adjustment path 3 is stored in the memory 19 of the microcontroller 23.
  • the opening in the window frame 18 is completely released from the window pane 1 (pointer 12 points to FIG. 20).
  • the closed position pointer 12 points to 21
  • the opening in the window frame 18 is completely closed by the window pane 1.
  • a trapping recognition system is provided for safety reasons, which limits the excess force in a predefinable area during a closing operation, so that injury to body parts is prevented by trapping.
  • the area 8, in which the excess force is limited (typically about 20 cm) by the reference numeral 8 and the inactive area (inlet in the rubber seal) by the reference numeral 7 is indicated.
  • the prerequisite for an intact limitation of the excess force is the knowledge of the actual position of the window pane with respect to the window frame 18. This means that both during manufacture and from time to time during operation, an initialization of the system must be carried out the absolute zero position of the positioning movement is learned and possibly corrected.
  • a reference position to be checked must first be available. It is assumed that this has previously been determined in a manner known per se, e.g. by moving the window glass 1 in a first step by manual operation of the key switch 6 toward the closing position (end position 21), the blocking detection of the control device 4 has detected a blocking of the motor, and this blocking position has been defined as the reference position.
  • the invention checks whether this previously determined reference position is actually valid. This is done by the test procedure according to the invention.
  • the window pane 1 is completely opened. This opening is effected in a window lifter meaningful way by a manual user action on the key switch 6, but could also be done automatically. During this opening movement, the blockage detection is active again and it is observed whether a mechanical blockage occurs. If at the end of the opening movement it is clear that no mechanical blocking occurred, then the validity of the previously determined reference position is given.
  • the before Defined reference position corresponds to the actual situation (ie, in the first step, in fact, the upper stop 11 was approached and this position - in accordance with the reality - is correctly considered by the control device as zero movement point).
  • Control device 4 does not release the automatic operating mode for closing. This can not lead to an impairment of the safety function of the adjustment, since a safety-critical, automatically running closing operation on the control element 6 can not be triggered.
  • the full functionality of the window regulator i. Manual and automatic mode of operation, is only (again) available when the user by manual operation on the control element 6 first causes a complete closing and then a complete opening of the window, and the reference position determined in the closed position after completion of the
  • Opening movement of the test program could be validated.
  • the position validation ensures that the determined reference position coincides with reality matches.
  • An autonomous closing procedure is only possible after successful validation of the reference position.
  • the embodiment of the invention shown here is of course possible analogously with the reverse direction. So it can be e.g. also be initialized at the lower end position 20, the reference position for the first time and be validated with the complete closing of the window 1. However, this is unusual, since the accuracy of the upper stop 11 (rubber seal) in a window lifter is more important (test rod 4mm).
  • the invention is not limited to automotive adjusting devices for windows or sliding roofs, but also applicable to other safety-critical adjustment.
