Definitions

  • the invention relates to an electrical central locking device for motor vehicles according to the preamble of claim 1.
  • the invention relates to a method for electrical central locking according to the preamble of claim 8.
  • DE-OS 29 11 630 is a combined with a lock cylinder switch for actuators on the driver's door.
  • the actuators are assigned locks in the other doors, in particular a rear door.
  • the centrally controlled locks have a rotary latch, a pawl and a locking device with a locking lever.
  • the locking lever is connected to the actuator assigned to it, specifically to a drive rod protruding from the actuator, which moves the locking lever in one of two end positions. One end position corresponds to the unlocking position and the second end position the locking position, between which a locking stroke has to be covered.
  • the drive rod can be coupled to an actuating slide which has a toothed rack, which in turn is connected to a reversible servomotor via a gear.
  • the actuator rod can thus be moved linearly back and forth as long as it is coupled to the actuating slide.
  • the coupling and uncoupling of the actuating slide and a possibility for locking the drive rod are not provided in the generic central locking device to be further developed according to the present invention.
  • a microswitch is further arranged in the area of the actuating slide, specifically on a cam-like elevation, which is switched in a certain position of the actuating slide.
  • this microswitch has a function which is of no further interest here in connection with an additional anti-theft device, but in principle it can also be used to emit a switching signal in an end position of the actuating slide which stops the servomotor.
  • the central locking is carried out in such a way that the switch which can be actuated with the key of the locking cylinder on the driver's door controls circuits for the actuators via a locking circuit and an unlocking circuit.
  • the servomotors of the individual actuators can be switched off by the microswitch when the desired next end position of the drive rod has been reached.
  • Locking or unlocking can also take place via a safety button on the inside of the door, which is connected to a safety lever on the locking device via a further rod. Finally, in the normal way through the Lock cylinder and an actuating rod acting on the locking lever are performed.
  • damping elements made of a shock-absorbing material have been provided in the actuator at the end of the movement path of the actuating slide.
  • damping elements in particular made of rubber, reduce the noise level and reduce wear, but the problem described is only incompletely solved, since only relatively small strokes of the actuating slide can be consumed by the damping element, even if an end position is present even with an unfavorable tolerance Security should be achieved.
  • the present invention is therefore based on the object of an electrical central locking device at the beginning mentioned type and a corresponding method for electrical central locking so that the end positions of the locking device can be reliably reached even with unfavorable tolerances, but that despite other unfavorable tolerances there is not too much kinetic energy in the central locking device that does not lead to the end or locking process is usable, but causes wear and noise.
  • the essence of the invention is that the electromechanical actuator does not travel through its stroke independently of the locking device connected to it between two fixed end positions. Rather, starting from a first end position, taking into account the predetermined stroke, a switching position is determined in which it is possible to intervene in the circuit of the actuator, ie the servomotor, before the next end position is reached, in order to control this next end position with certainty, but in to reduce the kinetic energy in the actuator in the last movement phase in such a way that no unnecessary knocks or bumps occur in the actuator, the transmission elements or the locking control device. Reaching this switching position is signaled by the fact that the positions of the actuator are steady and not only on a fixed one Position to be recorded.
  • the position transmitter In accordance with the position signals formed by the position transmitter, it can further be determined which time interval - at a given actuating speed - is still likely to expire until the next end position is reached. The current for this actuator is then controlled in accordance with this time interval in its movement phase after the switching position has been reached.
  • a particularly expedient measure for controlling the current through the actuator is specified in claim 2. Then three time interval areas are recorded with a discriminator, into which middle, larger and smaller time intervals are classified. Depending on the differentiation result, the current through the actuator is switched off after the switching position has been reached, maintained or reversed in its direction. Depending on the current situation, the actuator will run into the next end position only due to the momentum or inertia when the switching position is passed through, or the current will be maintained to the next end position when there is still a relatively large resistance to be overcome to reach. If, on the other hand, it is to be feared due to the situation at the switching position that the actuator runs into the end position too quickly, the movement is braked by countercurrent.
  • the switching position suitable for the respective locking device is formed by the means specified in claim 4, preferably calculated by adding or subtracting constant stroke to the stored initial end position.
  • the initial end position is the position that the locking device and thus the drive rod of the actuator assumed during the last electromechanical actuation or actuation by a lock cylinder or safety button. - Reaching this switching position during the current movement of the actuator is derived from the position signals continuously output by a potentiometer, which are compared with the previously determined target switching position.
  • the reaching of a switching position can be determined at least approximately by means of even simpler means that detection means of the current drop of the actuator are provided according to claim 5.
  • the simplified detection of this switch position is primarily intended for doors that are not themselves operated directly to control the central locking device.
  • the design of the electrical central locking device with the logic switching means enables an additional function by first detecting whether all locking mechanisms are the same Status - locking or unlocking - have accepted. With the intended use of electrical means, in particular a microcomputer, this configuration is particularly inexpensive and uncomplicated, without the need for mechanically complicated elements. This configuration thus enables locking errors to be signaled to the driver.
  • the times at which the end positions are reached can be staggered in time. This further reduces the maximum noise level.
  • a locking device of a lock is designated 1.
  • the locking device can be actuated by a safety button 2 for internal safety via a safety lever 3 shown broken off.
  • the locking device can be influenced by key actuation of a lock cylinder, not shown, via an indicated actuation rod 4. This actuating rod engages similar to another actuating rod 5 on a locking lever 6.
  • the actuating rod 5 is articulated on a drive rod 7 of an electromotive actuator 8.
  • the drive rod comprises a rack 9, in which a gear 10 meshes.
  • the gear wheel can be driven by a reversible servomotor 11, which is also connected to a potentiometer 12 designed as a signaling potentiometer.
  • the servomotor 11 can be supplied with a reversible actuating current via transistorized output stages 13 via lines 14, 15. Lines 16, 17 lead from the potentiometer 12 to an input circuit 18.
  • the output stages 13 and the input circuit 18 belong to a microcomputer 19 or are controlled by such a microcomputer.
  • Additional signal potentiometers of electromotive actuators for other locks can be connected to additional inputs of the microcomputer at 20, 21, so that their actuators can be controlled individually. - Instead, it is also possible to supply all actuators of the actuators via a ring line.
  • microcomputer The structure and function of the microcomputer are essentially described below based on the one locking device 8 shown, although several such locking devices belong to a central locking system.
  • the microcomputer includes a sequencer that determines the sequence of the operations shown below.
  • a block 20 it is first determined whether all locks or locking devices are in the same position. This is done in that position signals of the locking devices are continuously fed into the microprocessor via the input circuit 18 by the potentiometer 12 and corresponding potentiometers in the other actuators.
  • a waiting loop 21 is activated until the preceding condition is no longer met, for example by actuating the safety button 2 or a lock cylinder on the actuating rod 4.
  • a new position of the locking device 8 is transferred to the Microprocessor reported, the next criterion with block 22 determines whether a safety button or an associated locking device is in a new end position. If this condition applies, enter Command part 23 a command to move all locking devices into the new end position.
  • the new end position of the actuator or the actuated safety button stored in a memory 25 is used to determine a switching point of the actuator based on this starting end position, see block 26.
  • a block 27 designates a part of the sequence control which applies current to the servomotor for reaching the new end position until the switching point is reported by the associated potentiometer of the actuator. For the operations described below, this applies in particular to the actuators that were not the last to be operated manually.
  • the time interval remaining until the next end position is reached is determined in a computing part 28 when the switching point is reached. This time interval is determined on the assumption of a constant speed of the actuator at the time of the switching point. The speed can be derived from the continuously delivered position signals.
  • a subsequent discriminator 29 it is determined whether the determined time interval falls within a range of large, small or medium time intervals.
  • the current for the servomotor is initially maintained unchanged, since it obviously has to overcome even greater mechanical resistances.
  • the motor is braked by countercurrent in order not to move the locking device too suddenly into the new end position. If, on the other hand, a medium time interval is determined, the current through the servomotor is simply switched off, so that the servomotor assumes the new end position due to its momentum and the momentum of the moving parts of the actuator without running in too hard.
  • the potentiometer reports a further predetermined position of the actuator, from which the actuator is supplied with a reduced current, for example half of the normal current in the previous phase before reaching the switching position, in order to effectively reach the end position.
  • This additional switching function is indicated by block 30.
  • block 20 can also be used to determine whether there is a central locking fault because the locking devices are not all moved to the same position.
  • an additional function can be triggered by dispensing with an additional switch by one of the safety buttons, since block 22 reports when not all safety buttons are in an end position.
  • the safety button on the driver's door can be used to unlock a tank lock if the setting is arbitrary to half of its actuation distance, see blocks 31 and 32. If the driver's door button is completely unlocked or locked, the signal runs via a connection 33 into the On hold 21.
  • the staggered entry of all actuators into an end position can be achieved by varying the computing part 28 for the time intervals assigned to the individual actuators.
