Definitions

  • the invention relates to a motor vehicle door lock, with at least one electric motor drive, in particular Central locking drive, and with one of the drive Actuated output device, such as. B. gear, Output element, central locking lever, etc., the Drive at least within one to adjust the Power output device required time interval is, and being the drive within or at the end of Time interval - at the time of the blockade - (mechanical) is blocked.
  • the drive Actuated output device such as. B. gear, Output element, central locking lever, etc.
  • a motor vehicle door lock that described above Design is an electromotive central locking system realized.
  • this consists of a Electric motor, a transmission and an output element, which in an associated locking kinematics of known motor vehicle door lock engages (see. DE 35 26 501 C2).
  • the electromotive central locking is over an electronic control within the aforementioned Time interval energized, the energization time to Tolerance compensation is longer than the time is necessary to adjust the output device. In other words, this is the time of the blockade within the aforementioned time interval.
  • the entire output device is under mechanical tension because the drive remains unchanged electrical energy is applied and tries to Continue to turn output device.
  • the first sound is when reaching the end position (end stop or at Blocking time) produces, while the second, (quieter) Noise later when the power supply is switched off and the associated sudden mechanical Relaxation of the system is generated.
  • the first sound is usually desired and is considered by the user Feedback of the status "door closed" expected.
  • the following (usually quieter) noise on the other hand, cannot make any sense Information can be assigned so that this accordingly is perceived as disturbing. - Here she wants Total invention remedy.
  • the invention is based on the technical problem, one Motor vehicle door lock of the configuration described in the introduction so that annoying noises reliable due to elasticity in the output device be avoided.
  • the invention proposes generic motor vehicle door lock that the Powering the drive and thus its torque and / or speed along a ramp - and not abruptly as in the prior art - is reduced or will.
  • the invention is based on knowledge from that the product of speed and torque of the electric motor drive essentially of the (recorded) corresponds to electrical power. A decrease of the torque and / or the speed also goes with minimized (electrical) power consumption and vice versa.
  • the drive is energized usually pulse width modulated, d. H. the drive will by means of (rectangular) current pulses of a predetermined duration and frequency applied. Here with certain Duty cycles are worked. Below that is the Understand the pulse width compared to the period. On Duty cycle of 100% corresponds to one (Quasi) DC signal while a duty cycle of 0 % corresponds to no current supply. This is related be explained in more detail on the figure description.
  • the electric motor of the motor vehicle door lock described is usually by means of a semiconductor (usually FET transistor) within the electronic Controlled. That is how it is simply described the method of pulse width modulation realize.
  • a semiconductor usually FET transistor
  • a linear pulse width modulation control in terms of hardware and software support. It is always guaranteed that through the linear relationship between Motor current or absorbed motor power and torque the linear torque take-up or take-up is simply too is programming. Preference is given to a pulse width modulation clock frequency worked from 15 kHz or more, so that the control itself has no audible sound level generated.
  • a motor vehicle door lock is shown in the figures, which has an electric motor drive 1. In the present case, it is a central locking drive 1. This works with a gear 2, 3 together and works on a linearly adjustable output element 4. This output element 4 engages in one Locking kinematics in the form not specified a transmission lever 5 with other connected Lever in. In any case, with the help of the transmission lever 5 and the connected lever a central locking system realize how this is in the introductory detail German Patent 35 26 already mentioned 501, to which express reference is made be.
  • the drive 1 is at least within one for adjustment the output device 2, 3, 4, 5 required Time interval Z is energized, as is basically the case in FIG. 2 is shown.
  • Time interval Z is energized, as is basically the case in FIG. 2 is shown.
  • H. a current / time diagram the current supplied during the time interval Z
  • d. H. a - if you like that wants - volume / time diagram the one with the familiar approach associated noise
  • the energization starts with the starting point AZ which of course begins with the beginning of the Movement of the drive 1 coincides.
  • drive 1 runs after a certain time against an attack not expressly shown, and at the time of the blockade BZ.
  • G1 Since the current supply in the state the technology until the end of EZ after the expiry of Time interval Z is continued, it comes to the described elasticities in the output device 2, 3, 4, 5. If the energization suddenly occurs at the end time EZ falls away, a second sound arises - G2 - a, which should be avoided according to the invention.
  • the procedure shown in FIG. 5 is such that the torque curve shown over time t has the design shown. It can be seen that the drive 1 is energized during the entire time interval Z, but the energization and the torque resulting therefrom have a different course than in FIG. 2. In fact, a certain torque and thus a predetermined electrical power are used to act on the drive 1 practically up to the blocking time BZ. Then the energization of the drive 1 and thus its torque is reduced along a ramp R 1 , R 2 , R 3 shown .
  • the current supply to the drive 1 is pulse-width-modulated, as is shown in principle in FIG. 4.
  • the upper part of FIG. 4 shows a pulse duty factor t / T of approx. 50%, which, due to the linear dependence of the electrical power or the current and the torque, also corresponds to an approx. 50% torque loading of the drive 1.
  • a pulse duty factor t / T of approximately 80% (corresponding to approximately 80% of the maximum possible torque) is shown.
  • the torque curve according to FIG. 5 can thus be represented without any problems.
  • a maximum value is used, according to the exemplary embodiment 100% (for the pulse duty factor t / T and thus the torque).
  • This duty cycle t / T is reduced along the ramps R 1 , R 2 , R 3 , namely until the minimum value, in the present case 0%, is reached.
  • the maximum value (100%) three linear ramps R 1 , R 2 and R 3 are realized. They begin at the time of the blockade BZ, but can also be earlier by a predetermined amount M. However, this is not expressly shown.
  • FIG. 3 the basic structure of the electronic circuit for controlling the electromotive drive 1 can be seen in FIG. 3.
  • This has a microprocessor 6 in connection with a plurality of transistor / diode elements 7.
  • the microprocessor 6 specifies the direction for the drive 1 and also the pulse duty factor t / T and thus the shape of the ramp R 1 , R 2 , R 3 .
