Definitions
- the present invention is based on a method for monitoring and influencing an electric motor, which is assigned to a movable object, in particular on a motor vehicle, via an actuating device.
- Such methods are intended to enable the automatic adjustment of the movable object, which is, for example, a window or a sliding roof, and to take into account safety requirements which also result from legal regulations, among other things.
- these safety requirements relate to a limitation of the possible pinching force in the event that an object or body part is in the closing path of the automatically closing window or sunroof.
- the invention relates in particular to such a method in which a signal for stopping or reversing the motor rotation is generated as a function of a currently measured value of the motor current and a value of the motor current measured at a previous time.
- the present invention is based on the object of specifying a method with which the case of jamming can also be reliably detected and the window or sunroof can be stopped or reversed in good time, without, however, a complex calculation of energy balances, total forces, clamping forces, etc. and to require a tracking of the force curve over a time range encompassing an entire pinching process at equidistant measuring times.
- this object is achieved in that the motor current value l (t 0 ) measured simultaneously with a fixed edge (rising or falling) of a rectangular signal generated by a pulse generator proportional to the motor rotation is stored in a memory, and from an N (N> 1 ) relevant signal edges past measured, stored motor current value l (t. N ) using further parameters, a reference value l ref is formed, with which the currently measured motor current value l (t 0 ) is compared, and that if the reference value l ref is exceeded by the currently measured value l (t 0 ) the stop or reversing signal is generated immediately.
- the motor current signal l (t) provided by a signal conditioning device 1 is fed to a so-called “ripple detector” device 2, which generates a digital square-wave signal 2 ′, which is proportional to the motor rotation with the rising (or falling) edge of this square-wave signal 2 ', the analog value of the motor current signal l (t) is organized as a current motor current value l (t 0 ) into a shift register 3
- Adjustment position used. From a motor current value l (t. N ) stored a predetermined number N of measurements back, a reference value l ref is calculated in the microcontroller with the inclusion of further parameters, such as the supply voltage and part position-dependent setting parameters stored in a table memory 5, with which the current value measured motor current value l (t 0 ) is compared. If the currently measured motor current value l (t 0 ) exceeds the reference value l ref , a signal for stopping or reversing the motor rotation is sent to a motor control device 6, otherwise it is received the motor control device 6 sends a signal to continue the movement of the object to be adjusted by the motor in the same direction.
- a further development of the measuring method sees the introduction of a further criterion in the sense of a additional, necessary condition for generating the stop or reversing signal for the motor.
- a further criterion which is intended to confirm a tendency of the motor current that is present continuously over a longer period of time, a first counter 8 (“larger”) and a second counter 9 (“smaller”) are provided in a memory, which are used at the beginning of the adjustment both contain the value "zero".
- the currently measured value l (t 0 ) is now compared in each case with the directly measured value l (t *).
- the counter 8 (“greater") is increased by the value "one”
- the counter becomes 9 (“smaller”) increased by the value “one”.
- threshold values s Gr and s ⁇ * are defined, which are either lump-sum values for the entire movement sequence or saved as position-dependent table values in a table memory 5
- the method developed by the use of these counters 8 and 9 runs up to the point of comparison of the currently measured motor current value l (t 0 ) with the reference value l ref as described above, but now when the reference value is exceeded l ref is not immediately given the signal for stopping or reversing the motor operation by the currently measured motor current value l (t 0 ), but is first checked whether the additional condition that the content of the Counter 8 (“greater”) also exceeds the threshold value s Gr provided for this.
- Counter 9 is used to reset counter 8 ("larger") in such a way that in the event that the content of counter 9 ("smaller”) exceeds the threshold value s ⁇ * assigned to it , the content of the counter 8 ("greater”) is reset to the initial value "zero” regardless of the counter value currently present in this.
