Definitions

  • the invention relates to a motor vehicle door lock, with a motor-operated lever chain, and with an electric motor with associated control unit, wherein the electric motor transferred the lever chain in a predetermined position or applied from the predetermined position, and wherein the control unit uses data of the electric motor to its application.
  • a control is applied by an electric motor.
  • the start of the control against stop surfaces of a fork receptacle is detected by an associated increased power consumption or a timer and the electric motor drive is turned off as a result thereof.
  • detectors, switches or comparable sensors can in principle be dispensed with, by means of which typically certain predetermined positions of the lever chain, in this case a locking lever chain, are detected. So you know at this point switch or Hall sensors, with their help, for example, a position "locked” or the “unlocked” position of the respective locking lever chain are detected. This is necessary in order to stop the energization of the electric motor and consequently to prevent electrical and / or mechanical damage (cf., for example, DE 199 43 483 A1).
  • the state of the art has basically proven itself, as far as the sensory monitoring of individual positions of the lever chain is concerned. Because with the help of sensors or switches, the position can be defined, reproducible and clearly detected and reported to the control unit.
  • a generic motor vehicle door lock within the scope of the invention is characterized in that the control unit evaluates gradients of performance data of the electric motor for position adjustment of the lever chain.
  • the control unit in a generic motor vehicle door lock or to evaluate such a position of the above described construction also position signals of the electric motor for position adjustment of the lever chain.
  • the predetermined at least one position of the lever chain corresponds to a mechanical stop position. Since the lever chain is advantageously a locking lever chain and / or an actuating lever chain, the predetermined position corresponds to a locking lever chain, for example to its positions “locked” or "unlocked”.
  • the one or more predetermined positions may correspond to, for example, the operating positions "operated” or “not operated”. These all positions or positions of the respective lever chains correspond to a corresponding mechanical stop position as a rule. That is, once the relevant and previously indicated position, for example, “unlocked”, “locked”, “actuated” or “not operated” is reached, the lever chain in question in the confirmation direction can not continue to apply, because this is an associated attack prevented. This explains the realized mechanical stop position. - A renewed action on the electric motor must therefore correspond to the fact that the lever chain in question in the opposite direction, starting from the predetermined position experiences an act of loading.
  • the control unit in the context of the invention evaluates gradients of performance data of the electric motor. In this way, the position adjustment of the lever chain is determined, namely in the present case the achievement of the predetermined position or the associated mechanical stop position.
  • no threshold values of the current absorbed by the electric motor for example, in the sense of an increased current consumption are detected and evaluated at this point. Rather, it is a matter of the invention to detect and evaluate gradients of performance data of the electric motor. As the performance of the electric motor whose recorded current or the applied voltage come into question, because their product reflects the power absorbed.
  • the gradient is mathematically differential operators applied to a respective scale field.
  • the slope is determined as a rule, for example, the current increase per unit time of the current for acting on the electric motor.
  • a voltage change per unit of time can also be detected and evaluated in order to detect the reaching of the predetermined position by the lever chain.
  • a current-dependent voltage change can also be evaluated by the control unit. This means that the derivative of the voltage after the current is detected with the aid of the control unit and used for the application or non-admission of the electric motor.
  • the procedure is such that the time profile of the electric current is evaluated to act on the electric motor.
  • the control unit has a differentiator, which can be implemented hardware and / or software. With its help, the current change per unit time can be determined. If certain gradients are exceeded at this point, this is interpreted as reaching the predetermined position by the lever chain in the control unit. That is, the exceeding of a certain predetermined slope in the example case corresponds to the sensor signal, which for example belongs to the position "unlocked” or "locked”.
  • the control unit thus generally evaluates temporal current / voltage courses for driving the electric motor. For this purpose, the control unit differentiates the respective current / voltage curves in time or in time. A certain increase in the time of the current or the voltage at the electric motor is identified as a result of reaching the predetermined position.
  • the invention regularly proceeds in such a way that the control unit initially acts on the electric motor in its opposite direction following an activation command.
  • the current position of the lever chain as the starting point for the desired movement can be determined or verified. If, for example, the locking lever chain is "locked” in its position and an activation command is given in the sense of "unlocking", then the electric motor is initially charged in its opposite direction. This means that the electric motor in the example case - despite the already adopted position "locked” - again applied in the direction "lock".
  • the invention also provides a method for operating a motor vehicle door lock, as described in detail in claim 9 et seq.

  • a wired control of the electric motor via, for example, a key is possible.
  • the wireless control of the electric motor is typically realized via a radio remote control.
  • the wired loading by means of the key can be done by the key is inserted into a lock cylinder and rotated accordingly herein, for example, to realize the functional position "locked".
  • a motor vehicle door lock is made available, which is initially very simple and inexpensive. Because individual predefined positions of the inevitably realized lever chain can be queried and evaluated, as it were, without a sensor.
  • the control unit accesses gradients of performance data of the electric motor acting on the lever chain and evaluates these to the effect that the position of the lever chain can be deduced.
  • the invention is based on the recognition that a certain predetermined position of the relevant lever chain corresponds to the fact that the lever chain is mechanically blocked in at least one direction of movement. That is, the predetermined position corresponds to the mechanical stop position in the respective direction of movement. As soon as the electric motor travels "on block", the current absorbed by it rises sharply over time.
  • This current increase is evaluated in the example case. As soon as its gradient has exceeded a certain threshold value, the control unit concludes from the associated gradient of the absorbed current on the part of the electric motor that the predetermined position or mechanical stop position has been reached in the direction of movement of the lever chain.
  • the invention proceeds in such a way that the control unit initially acts on the electric motor in its opposite direction following such an activation command.
  • the electric motor is thus acted upon in the mechanical stop position so that it first - again - moves against the stop, which in turn is associated with a strong increase in time current in the example.
  • This can be evaluated and interpreted by the control unit to the effect that the lever chain as a starting point for their desired movement, in fact, the position assumed by the control unit based on the history unchanged. Proceeding from this, then the electric motor is acted upon in the opposite direction and the lever chain moves according to the desired activation command.

  • On the ratchet or the pawl operates a release lever 1, which is shown in Fig. 1 only in section and is connected to a central locking lever 2.

  • an outer locking with associated outer locking lever, outer locking element and indicated key 5 with associated lock cylinder 6 can also be realized at this point.
  • the central locking element 2 is acted upon by a control element 7 in the form of a driven pulley with two eccentric control pins 8.
  • the control pins 8 engage in a fork receptacle 9 of the central locking element 2, depending on the direction of rotation D of the control element or the driven pulley 7.
  • a lever chain or locking lever chain 2, 3, 4, 5, 6 is realized which comprises the central locking lever 2, the inner locking lever 3, the inner locking element 4 and finally the outer locking in the form of the key 5 including lock cylinder 6 composed.
  • the lever chain or locking lever chain 2, 3, 4, 5, 6 is transferred by the electric motor 10 in a plurality of predetermined positions, for example, in the positions "locked” or "unlocked”. In Fig. 1 the position "locked” is shown. In the present case, this corresponds to the fact that the right-hand control pin 8 in FIG. 1 has moved against a stop surface, consequently the predetermined position "locked” of the locking lever chain 2 to 6 corresponds to an associated mechanical stop position.
  • control unit 1 1 In order to now set the "unlocked" position of the motor vehicle door lock, the control unit 1 1 must first be acted upon accordingly. This is done in the present case by means of a merely indicated radio remote control unit 12. As a result, the control unit 11 ensures that the left in FIG. 1 control pin 8 dips into the fork receptacle 9 and the central locking lever 12 is pivoted clockwise about its axis 13, to The right in FIG. 1 control pin 8 comes to rest on the left stop surface of the fork receptacle 9, as explained in the principle of operation in detail descriptive DE 44 47 687 C2, which is expressly noted in this context.
