Definitions
- the invention relates to a method for determining the rotational position of the drive shaft of a DC motor by evaluating the current ripples contained in the armature current signal.
- the armature current signal of a DC motor comprises a so-called DC component and an AC component superimposing the DC component.
- the alternating component arises during operation of the DC motor as a result of the interaction of the magnet (field), armature winding and commutator of the DC motor. This manifests itself in a brief change in the induced voltage, which results in the ripple of the armature current signal.
- the current peaks contained in the armature current signal - hereinafter referred to as current ripples - occur with one rotation of the armature in a frequency which corresponds to the number of collector plates. If, for example, the armature has 10 collector lamellae, 10 current ripples can be recognized in the armature current signal.
- a counting of the current ripples can thus provide information about the current rotational position of the armature of the DC motor and thus also about an element driven by it within a predetermined movement distance.
- the analog armature current signal is digitized so that an appropriate count can be made.
- Methods of this type are used, for example, in the motor vehicle sector to control an adjusting drive, as are provided, for example, for window lifters and / or sunroofs.
- An essential element in the detection of the position of the pane is that when the pane is closed, in which the pinch protection can be switched off. Such a switch-off is necessary so that the disk can move completely into its upper block and into the seals provided there without the motor being switched off due to the increased load. If the current ripple is incorrectly counted to determine the position of the disk, it can happen that the input pinch protection is switched off too early or too late.
- thermal switches are arranged in the electrical connection between the DC motor and the evaluation electronics or the voltage source. This is to avoid overheating of the direct current motor, for example in the event of a faulty control, and to reduce the dangers arising from such heating.
- any electrical connection between the DC motor and the evaluation electronics is interrupted.
- An actuation of the thermal switch has the result that the current supply to the DC motor is immediately interrupted. Nevertheless, the DC motor will continue to run for a certain time and will not come to a standstill immediately. This means that the armature of the direct current motor and, accordingly, also the window pane moved by the direct current motor actually moves on by a certain amount.
- position detection by means of detection of current ripples to take account of this overrun in the position determination is not possible due to the interrupted electrical connection between the DC motor and the evaluation electronics.
- the invention is therefore based on the object of developing an aforementioned generic method in such a way that even in the event of a sudden interruption in the electrical connection between the DC motor and the evaluation electronics, it is possible to determine the position of the armature of the electric motor with sufficient accuracy is possible.
- This object is achieved in that in the event of an interruption in the electrical connection between the DC motor and the evaluation electronics, an approximate determination of the amount of rotation angle covered during the runout of the armature of the DC motor is made by determining the number of current ripples expected to be expected during this runout.
- the method according to the invention is characterized in that in the event of an interruption in the electrical connection between the DC motor and the evaluation electronics, an approximate determination is made - An estimate is made with regard to the number of current ripples to be expected with such a motor stopping. It is advisable to include in this determination parameters that have characterized the operation of the DC motor before it was switched off. For example, the period of a reference current ripple and / or the armature current can be used as parameters in the approximate determination. To simplify the calculation, certain simplifications can be provided, for example, it is assumed that the speed decrease of the armature of the DC motor will be linear until it comes to a standstill.
- J is the moment of inertia of the DC motor
- n is the speed of the DC motor
- t is time
- M is the load
- T is the period of a reference current ripple and ⁇ is the amount of rotation of the armature, or with reference to the period of the last detected current ripple:
- a sufficiently precise position determination with regard to the position of the armature and corresponding to the position of an element driven by the DC motor, taking into account the amount of rotation angle traveled by the armature during the, can be carried out with sufficient accuracy even in the event of a sudden interruption in the electrical connection between the DC motor and the evaluation electronics Phase out.
- the entire system had to be renormalized, so that the automatic disk run-up was switched off until such renormalization took place. In principle, this is no longer necessary with the subject matter of the invention.
