Definitions

  • the invention relates to a window regulator, and a control device of a window regulator and a method for controlling a window regulator according to the preamble of claims 1 and 10.
  • a device for such a method is for example from US 2002/0190680 A1 known.
  • the solution ensures anti-pinch protection over the entire adjustment range, which also meets very high safety requirements.
  • the adjusting force is sufficiently large, even in the areas of stiffness, and that an adjusting device adjusts a translationally displaceable component taking into account the external influences acting on the vehicle body in accordance with the operator's material.
  • External influences are here understood to mean the forces acting on the vehicle body or acceleration forces which are not directly caused by the adjusting device or by a drive device, but occur, for example, because of the poor condition of the driving route (driving through a pothole) or when closing a vehicle door.
  • the regulation of the adjustment force or the excess force is preferably carried out as a function of the direction of movement of the translationally adjustable component and of the predominant direction of action occurring acceleration forces such that the adjusting force is always less than or equal to the permissible pinching force.
  • the threshold value is preferably reduced. In the case of occurrence of the closing movement opposing acceleration force, the threshold is increased. In this way, the adjusting force is always sufficiently large, so that the closing movement continues safely and an anti-trap protection is ensured.
  • a regulation of the adjustment force or the excess force is interrupted and a threshold value is predetermined such that the adjustment force is always less than or equal to the permissible pinching force.
  • the time span is for example 100 ms.
  • the acceleration forces acting on the vehicle body are preferably detected by a sensor, for example by a digital signal providing sensor.
  • Digital signals can be processed easily in a control electronics.
  • To set the control can be evaluated by the control and electronic control single or multiple, temporally one behind the other signals of the sensor. The repeated evaluation of the signals of the sensor makes it possible to reliably identify a simultaneous occurrence of the acceleration forces caused by external influences and the forces caused by a trapping case.
  • a motor drive device for a motor vehicle is known.
  • the rotation of the motor is stopped immediately when the movement of the window with an engine turned obstructs an obstacle.
  • the motor drive device serves to open and close the movable part (window) and can be selectively operated and stopped.
  • An electrical current measuring device measures the magnitude of the current flowing through the motor in a start-up compensation time, a current magnitude change detector detects an amperage increment from the detected current at each constant time interval, and a motor controller supplies a first or a second control signal to the motor drive device the first signal depending on the polarity of the Stromstrkeninkrements the engine operation continues and with the second signal, the engine is stopped immediately.
  • Two selector switches indicate the direction of rotation of the motor, a pair of key switches for the respective motor directions and two self-holding circuits for the two directions of rotation of the motor allow rotation of the motor upon actuation of one of the key switches.
  • a control device for a powered barrier is known, which is independent of their configuration and can be remotely operated and directly operated in various ways.
  • Security measures use an adaptation strategy to provide highly sensitive obstacle detection by learning the power requirements of the system and providing it with a safety margin.
  • the control system allows completely manual handling of the barrier.
  • Information is stored about the actuation force needed at each point of the tailgate trajectory along its predetermined trajectory to close the tailgate. Values are stored in four multidimensional arrays. The dimensions of the arrangement are direction of movement and position. The direction of movement is opening or closing. The position is any number of divisions of the prescribed course.
  • the actuation force (fmem), the time derivative of the actuation force (dfmem), the fluctuation of the actuation force measurements (vfmem) and the fluctuation of the measurements of the derivation of the actuation force according to time (vdfmem) are determined. Other stored values include the number of tailgate opening and closing operations, without the detection of an obstacle, the number of obstacles detected, and the average operating force over the last n minutes.
  • the operation of the tailgate takes place at time t, at which the tailgate is in the partial area p of their path along the predetermined path, and the direction of movement of the tailgate is d.
  • the memory values are used to determine an obstacle as follows:
  • the deviation is adjustable.
  • the deviations (both fmargin and dfmargin) can be constructed as a function of vfmem [d, p] and vdfmem [d, p]. This means that the deviation itself is a function of the position and varies with each position over time as the force varies. As a result, with an increase in the temporal or local change of the force, the deviation is also increased .
  • a further extension is to modify the stored forces (either one or both of fmem (p) and dfmem (p)) as a function of any external sensor (eg, a temperature sensor) to account for known and predictable environmental influences.
  • any external sensor eg, a temperature sensor
  • k1, k2, k3, k4, k5, k6, k7 and k8 affect the speed with which the system learns and therefore how the system responds to a changing environment. Typically these values are chosen so that k1, k3, k5 and k7 are much smaller than k2, k4, k6 and k8.
  • the object of the present invention is to further develop a control device of an adjusting device of a motor vehicle. This task is done by the control device with the features of claim 1 and the window with the features of claim 19 and by the computer program product with the features of claim 21 solved.
  • Advantageous developments of the invention are specified in the subclaims. For further development of the invention, in addition, the features of the subclaims are particularly advantageously combined with one another and with features of the cited prior art.
  • a control device of an adjusting device of a motor vehicle is provided.
  • the adjusting device is preferably a motor vehicle window lifter.
  • the control device may be formed on a semiconductor chip, as a so-called “smart power solution", ie as integrated, intelligent power electronics, or consist of a plurality of electronic and / or electro-optical components.
  • the control device has at least one arithmetic unit for controlling a drive of the adjusting device, which consists for example of pure hardware in the form of a hardwired program structure and / or is freely programmable. This arithmetic unit is for example a microcontroller.
  • the arithmetic unit is set up to stop an adjustment movement of the drive or to start a process for stopping the adjustment movement of the drive when a signal correlating to the torque of the drive exceeds an actual response threshold.
  • This function may also be referred to as an anti-trapping function of an adjusting device.
  • the signal correlating with the torque of the drive is, for example, the drive current and / or its time change, the speed of the drive and / or its time change and / or a force acting on the drive and / or its change.
  • Other torque correlating signals may be evaluated.
  • the correlation is understood to mean any form of dependence on the speed.
  • the type of correlation is dependent on the size to be evaluated.
  • the correlation is a speed-torque characteristic of the drive, in particular an electric motor.
  • the threshold is then exactly when it is compared to the anti-trap function with the measured signal for the same adjustment position. Furthermore, an adapted threshold is determined for a subsequent adjustment by evaluating the current threshold together with the current signal and, if appropriate, further influencing factors.
  • the threshold is not a fixed threshold, but a variable value that is changeable by the arithmetic unit.
  • the torque correlating signal is compared and controlled in case of exceeding the current threshold of the drive in response to the comparison result.
  • This current threshold is preferably adjusted during the adjustment by the current threshold is changed in response to the temporal and / or local change of the signal such that with increasing temporal or spatial change of the signal, the current threshold is reduced. For a reduction of the current threshold, this is brought closer to the signal to be compared, so that the distance between the signal and the current threshold is reduced. If, for example, the drive current or a force is evaluated as a signal, the value of the same is increased to reduce the current threshold. For example, if the reciprocal of the speed is evaluated as a signal to reduce the current threshold, the value of the same lowered.
  • the current amount of the value of the current response threshold is preferably changed here.
  • the temporal or spatial change of the signal means both the first and any further derivation of the signal by location and / or time.
  • the temporal and / or spatial change of the signal also includes differences of the successive values of the signal, if this is time-discontinuous or location-discontinuous due to the measurement resolution.
  • the computing unit can be set up, for example, by a program that is recorded in the arithmetic unit and with which the arithmetic unit is correspondingly configured.
  • this program can also be hardwired (ROM) integrated in the arithmetic unit.
  • ROM hardwired
  • This program executes a procedure that allows the evaluation of the correlating signal.
  • This program can be stored in a digital storage medium, for example a floppy disk or a non-volatile memory (EEPROM).
  • a particularly advantageous embodiment of the invention provides that the arithmetic unit is set up to change the current threshold only under the condition that the temporal or spatial change of the signal exceeds a minimum change value. Below this minimum change value, therefore, there is no change in the current response threshold as a function of the temporal or local change of the signal. However, this is a change the threshold, which is due to other dependencies, not excluded.
  • the threshold can be adapted depending on other values.
  • values of the signal from at least one previous adjustment for the adaptation of the response threshold are evaluated and stored.
  • the respective current value of the signal is weighted by a factor and averaged with values of previous displacements, which are all assigned to the same adjustment location.
  • Another type of averaging can be done by averaging previous values of the signal of the same adjustment and using the determination of the current response threshold, in particular using an offset.
  • the arithmetic unit is set up to additionally change the threshold as a function of the course of the average amount of the signal.
  • the threshold is changed depending on the amount.
  • this can also be done by averaging the signal with equal or different weighting factors for the individual values of the signal.
  • the adapted threshold is hereby adapted to slow changes in the magnitude of the signal over the displacement and, for these slow changes in magnitude, advantageously set at a substantially constant distance from the mean of the signal. Slow changes in magnitude can be caused, for example, by changes in the mechanical stiffness caused by changes in temperature compared with previous adjustments, so that an adaptation of the adapted response threshold for a respective adjustment position associated with the binding is advantageous.
  • the averaging can take place, for example, over the last 4 to 8 values of the same adjustment or over 2 to 6 values of preceding adjustments, which relate in each case to the same adjustment locations. As a result, short-term, insignificant changes do not significantly affect this mean. If the correlating signal is a rotational speed of the drive, it is therefore advantageously provided that the arithmetic unit for changing the threshold is additionally set up as a function of an absolute rotational speed of the adjusting device.
  • the arithmetic unit is set up to change the current or the adapted threshold in addition to a stiffness of the adjustment.
  • the rigidity of the adjusting device can advantageously have been determined by the arithmetic unit or this is loaded before commissioning as a parameter set in the arithmetic unit.
  • the rigidity can be composed of different individual stiffnesses of the adjustment system.
  • a preferred development of the invention provides that the arithmetic unit is set up to mathematically correlate the change of the current response threshold to the temporal or local change of the signal.
  • the change of the signal is not just a trigger to change the current threshold, but the value of the change of the current threshold is also related to the value of the change of the signal.
  • the correlation is the change of the current response threshold as a function of a characteristic field.
  • This map is preferably stored in the arithmetic unit and in particular adaptable by the arithmetic unit.
  • the change values of the current response threshold are assigned to the temporal or local change of the signal.
  • the map can take into account further dependencies of further measured values or control signals and provide several sets of map values for this purpose.
  • the correlation is the change of the current response threshold as a function of a mathematical function.
  • the mathematical function outputs the required change value of the current response threshold as the output variable.
  • the temporal or local change of the signal serves as input of the function.
  • other input variables can be evaluated by the function.
  • parameters of the function are changeable, in particular, by the arithmetic unit or by other electronics.
  • the mathematical function is a continuous function.
  • a particularly simple embodiment of this embodiment variant provides that, for the lowering of the current response threshold, the change value of the current response threshold is proportional to the temporal or local change of the signal.
  • These Design variant can be particularly advantageous combined with the minimum change value.
  • the mathematical function can also be a step function which enables a simplified calculation of the current response threshold.
  • the invention also relates to a window with a drive and an adjustment mechanism for adjusting the position of the window.
  • this window has the previously described control device for controlling the drive.
  • the invention relates to a digital storage medium, in particular a floppy disk, with electronically readable control signals, which can cooperate with a programmable arithmetic unit, that a method is performed by stopping an adjustment of a drive of the adjustment or started a process for stopping the adjustment of the drive when a signal correlating to the torque of the drive exceeds an actual threshold.
  • the current response threshold is changed as a function of the temporal or spatial change of the signal by lowering the current response threshold with increasing positive temporal or spatial change of the signal.

  • the invention relates to a computer program with a program code for performing a method by an adjustment movement of a drive of the adjustment stopped or a method for stopping the adjustment of the drive is started when a correlated to the torque of the drive signal exceeds a current threshold and by the current threshold is changed as a function of the temporal or spatial change of the signal, provided that the program product runs on a computing unit.

  • the value of the maximum trapping force F 1 max also depends, in addition to the dependence on the kinetic energy present at the time of tucking in t 1 , on the sum of the rigidity of the window regulator system and the stiffness of the trapped body part.
