Abstract

The circuit arrangement has a locking mechanism that holds a motor vehicle door in a closed position or open position. An actuator is particularly equipped at an outside door handle (19) or an inside door handle (18). An electric drive, particularly an electric motor (11) is equipped for driving the locking mechanism. An additional electrical circuit element (13) is arranged within the current flowing circuit of the motor. Independent claims are also included for the following: (1) a method for controlling a locking unit of a motor vehicle door; and (2) a controller for a locking mechanism to hold a vehicle door in a closed position or open position.

Description

  • The present invention relates to a motor vehicle lock according to the preamble of claim 1. These motor vehicle locks are preferably used in side doors, trunk lid, tailgates and folding windows of motor vehicles application.
  • As a generic state of the art shows the EP 0 589 158 B1 a lock with a catch which, in operative connection with a striker, holds a vehicle door in a closed position. A pawl and the catch are in the closed state in positive connection. This positive connection between the catch and pawl can be solved by means of an electric actuator by the electric actuator exerts a force on the pawl, which causes a pivotal movement of the pawl and solves the positive connection between the catch and pawl.
  • The electrical power supply of the electric actuator via a controller that is powered by the vehicle battery. The signal for opening the vehicle door gets the control of two micro-switches, which are actuated via the outside door handle or the door inner handle of the motor vehicle door. These signals are used by the controller to enable the power supply of the electric actuator.
  • For safety reasons, a relay is connected to the controller, which interrupts the power supply to the electric actuator when z. B. the vehicle is not, whereby the electric actuator of the central automotive electronics is not controlled.
  • Another prior art is in the DE 103 60 422 A1 described. The DE 103 60 422 A1 shows a circuit in which the outside door handle and the door inside handle each actuate a sensor. The sensor consists of two switches and two resistors. A switch and a resistor are connected in series, with the series-connected resistor / switch elements arranged in parallel. The resistors are used for resistance coding, with the switches closing the circuit. Due to this resistance coding, the controller can detect a faulty signal and react accordingly. Furthermore, when disconnecting a line, the signal can be forwarded to the controller via the second parallel-guided resistance / switch element. The controller is then connected directly to the lock or to the electric actuator.
  • As both at the EP 0 589 158 B1 as well as at the DE 103 60 422 A1 the controller is connected directly to the electric actuator, an accidental opening of a motor vehicle door due to a faulty signal of the controller is possible. In this case, the vehicle door, z. B. while driving, open and endanger both the vehicle occupants and nearby vehicles. To avoid this, is in the DE 100 42 191 A1 a lock described that when operating the inner door handle or outside door handle mechanically engages the electric actuator. For this purpose, a mechanical coupling is arranged between the electric actuator and the pawl, which is actuated via the outside door handle and / or the door inner handle. With unconfirmed door outside / resp. Inside door handle is the mechanical connection between the electric actuator and pawl interrupted. If the electrical control element is energized due to a fault in the control, the movement runs into the void. The vehicle door does not open. If the inside door handle and / or the outside door handle is actuated, the mechanical connection between the electric actuator and the pawl is closed (engaged). At the same time a signal is sent to the controller by the operation of the outside door handle and / or the door inner handle, which energizes the electric actuator. Since the mechanical connection between actuator and pawl is closed (engaged), the movement is transmitted to the pawl and the vehicle door is opened. However, a mechanical coupling consists of several elements that are sensitive to tolerances and their installation consuming. Furthermore, a mechanical clutch generates noises and is sensitive to dirt and icing.
  • The present invention has for its object to provide a switch assembly for a motor vehicle door, a method for controlling a barrier and a control for a barrier, by means of which an accidental opening of the vehicle door to avoid while avoiding a mechanical coupling.
  • To solve this problem, a circuit arrangement according to the invention has the features specified in claim 1, an inventive method for controlling a barrier work has the features of claim 12 and the controller according to the invention has the features specified in claim 20 features. Advantageous embodiments of the invention will become apparent from the respective dependent claims.
  • The circuit arrangement according to the invention is used for locking devices of motor vehicle doors. This is understood by Motor vehicle door All moving parts of a motor vehicle (eg side doors, sliding doors, wing doors, trunk lids, tailgates, hoods, folding windows, fold-up hoods for pedestrian protection or headrests that change their position in a crash), which by means of a blocking mechanism in a predetermined position being held. Locking devices are understood to be mechanical components which are usually positioned in the door and, in conjunction with a counterpart on the body, hold or open the motor vehicle door in a closed position. Structurally, the barrier systems are positioned in the locks of the vehicle doors.
  • The opening movement of the locking mechanisms is generated by an electric motor. Alternatively, however, a motor / gear unit, a linear motor, a solenoid, a shape memory element or any other device can be used which converts electrical energy into motion.
  • The motor current is enabled in the circuit arrangement according to the invention by a control module. In addition, an electrical switching element is arranged in the motor power line. This switching element is preferably a switch, reed switch, Hall sensor, buttons, relays or other switching element that interrupts the motor power line in the rest position. Mechanically, this electrical switching element is actuated by the inside operating lever or the outside operating lever. Upon actuation of the inside operating lever or the outside operating lever, a signal is sent to the control module, whereby the control module releases the motor current. The signal can be generated by any means. At the same time, the electrical switching element in the motor power line is switched to the closed position by the operation of the external actuating lever or the inner actuating lever. The motor current can thus drive the motor, whereby the locking mechanism opens the vehicle door. If the motor current is switched due to a fault in the control module without the inside operating lever or the outside operating lever being pulled, the electric switching element between the control module and the motor remains in the open position. The engine can thus not start and the locking mechanism does not open the vehicle door.
  • If the electrical switching element to be used exclusively as a security element, d. H. the electrical switching element is primarily used to interrupt the motor power line and thus the safety function, it is recommended to use a button, preferably a closer. For the use of a closer speaks the reliability as well as the ease of installation both during positioning and during installation.
  • However, if the electrical switching element, as described later, generate and / or forward further functions or further signals, a changeover switch is to be preferred. In this case, a changeover switch must be selected in such a way that is automatically switched to the "off position" in O position and in O position, the motor current is interrupted.
  • When positioning the electrical switching element, two variants are to be preferred. In the first variant, the electrical switching element is positioned as close to the engine. This is to be preferred for safety reasons, because errors, eg. B. due to short circuits because of damaged lines, not to open the door. However, in this variant, the operating force must be passed from the outside door handle or door handle to the electrical switching element. The second preferred variant is to position the electrical switching element in a door handle unit (inside door handle and / or outside door handle). The positioning of the electrical switching element in a door handle unit causes a simple installation, since the actuating force can be relatively easily transferred to the electrical switching element from a design point of view. The electrical switching element can also be positioned at any other point in the vehicle, if this offers advantages due to the overall view of the vehicle.
  • If additionally a second signal is to be generated with the electrical switching element, a two-pole switching element is recommended. In this variant, all switching elements can be used, the at least one input and at least two outputs, z. As switches, reed switches, Hall sensor based circuits, buttons or relays include. In this variant, in the unactuated state, the electrical switching element is installed in the motor power line such that the motor is de-energized. A signal current flows via the second pole of the electrical switching element. This signal current can flow both permanently and pulsed over the line. In order to achieve a better energy balance, but the signal stream can only after a wake-up z. B. by a signal which is introduced in any manner in the control module, are introduced into the controller. If in one of these variants the electrical switching element is switched from position a (motor current line is interrupted and signal current line is closed) to position b (motor current line is closed and signal current line is interrupted), the control module releases the motor current due to the signal line signal , At the same time, the motor current connection is closed in position b of the electrical switching element, so that the motor lifts the pawl.
  • With a further variant of the circuit arrangement according to the invention, a closing aid can be actuated. With a closing aid, the locking parts can be pulled by motor from the pre-catch to the main catch. Since there is a risk of trapping of objects and body parts in this automatic process, the closing process must be interruptible. During the closing process, however, the pawl also falls into the main catch. Therefore, the locking parts must be moved to the open position when interrupting the closing process. This is given in the inventive arrangement of the electrical switching element, since the interruption of the closing process proceeds as follows: The control module stores the beginning of the closing process. During the closing process, a signal current flows via the electrical switching element to the control module and is evaluated there. In Einklemmfall is pulled on the inner door handle or outside door handle. As a result, the electrical switching element interrupts the signal current. At the same time the supply of the motor current is closed. After the control module detects that the signal power has been interrupted, the control module stops supplying power to the closing assist motor, causing it to stop. At the same time, the control module switches on the current for the motor of the blocking parts. Since the motor power line of the Sperrteilemotors is closed by the operation of the electric switching element, the pawl motor is driven and lifts the locking parts.
  • In all variants, it is possible for both a motor current and a signal current to be conducted via the same poles and the same line, from the control module to the electrical switching element. If the electrical switching element is in the passage position for the signal current, a small current flows at a reduced voltage between the pole of the control module and the electrical control element. However, if the signal line is opened and the motor power line is closed, the much higher motor current and the voltage of the vehicle electrical system flow via the same poles and lines. This variant simplifies the circuit design and thus the costs.
  • Door inside handle and outside door handle can mechanically act on the same electrical switching element with appropriate structural design of the door. This reduces the electrical circuitry and electrical sources of error z. B. the chafing of the electrical lines. To realize this, a mechanic is necessary. Alternatively, however, the door inner handle and the outside door handle can each act on different electrical switching elements. Which variant is preferable depends on the conditions in the vehicle.
  • Next, the control module, the signal stream only after evaluation of further sensor signals z. B. crash sensor, speed detection or sensors for the closing states, free. So z. B. by introducing signals of the crash sensor into the control module, the energizing of the pawl motor are turned off. This circuit prevents the door from being opened by actuation of the inside door handle or outside door handle by centrifugal forces or by deformation of the door.
  • The method for driving a barrier protects a motor vehicle door against accidental opening. The prerequisite is that the blocking mechanism can be opened automatically. This is preferably achieved by an electric motor. The motor is controlled by a control module. This control module gets an electrical signal to open the door. This signal is processed in the control module and releases the motor current. However, an additional electrical switching element is arranged in series between the control module and the engine. This electrical switching element may be any element that closes a circuit. The electrical switching element is actuated by the outer or inner handle. Only when this electrical switching element has closed the motor circuit, the engine can start and open the barrier. Now switches the control module, due to a fault, the motor current free, without an actuator was activated, the locking mechanism is not opened because the circuit is interrupted due to the electrical switching element.
  • The electrical switching element remains closed only as long as the actuator is activated. This serves to ensure the reliability of the process. If a latching electrical switching element is used, there is the possibility that the circuit is closed even when the actuating element is not actuated, and in the case of a faulty activation of the motor current by the control module, the blocking mechanism opens the motor vehicle door.
  • When using a changeover switch as an electrical switching element, both the motor current can be passed through the changeover switch, as well as a signal current to control the control module. It is understood by changeover switch all switching elements, the at least one input and two outputs z. As switches, reed switch, Hall sensor, buttons, relays, have. For this purpose, a signal current flows via a pole of the changeover switch to the control module permanently, pulsed or after a wake-up process. If this signal current is interrupted by the changeover switch, the control module detects this and releases the motor current. By switching the changeover switch to the other pole, the motor circuit is closed, so that the motor Barrier opens. Thus, this variant saves material and installation costs.
  • With the control signal, other functions of the control module can be activated. It is particularly advantageous if, in addition to the additional function, the blocking mechanism also has to be brought into the open position. This is z. B. when interrupting a Zuziehvorgangs required. For this purpose, the control module is known when a Zuziehvorgang takes place. If this is interrupted, the changeover switch must be switched. The control module detects the interrupt command by interrupting the signal and stops the power supply to the closing motor. At the same time, the control module releases the motor current for the blocking motor. Switching the toggle switch closes the circuit of the ratchet motor, causing the ratchet to move to the open position.
  • Since the changeover switch has one input and two outputs and the signal current flows through one pole and the motor current flows through the other, both the signal current and the motor current must flow via the supply line. The same applies to the switching flag. These also flow both a motor current and the signal current. Through this circuit, the number of lines and thus the installation effort is minimized.
  • For design reasons, it may be necessary to use two electrical actuators, for. B. one for the outside door and one for the inside door handle to use. Since door outer and inner door handle are spatially separated from each other, usually the inner door handle in the drying room and the outside door handle is positioned in the wet area, it is usually simpler to replace the electrical mechanical electrical connection elements.
  • In addition to the signals of the electrical switching element, it is possible to evaluate the control module and other signals. So there is the possibility that z. B. sensors for the closed states or the speed detection, or the signals of the crash sensor are evaluated. Thus, the control module may be configured such that the engine for the locking elements is not energized when the vehicle is moving (Geschwindingkeitserkennung), the vehicle is in the locked state or is currently in a crash situation. The control module can also process signals to open the barrier. So the control module z. B. energize the motor when an external sensor detects a pinch. The cases listed here are only examples. The type and variety of signals to be evaluated are limited only by the equipment of the vehicle.
  • The control of the invention prevents accidental opening of a vehicle door, z. B. by a false signal of the control module. Under control module is a unit understood, the electrical signals z. B. switch signals, sensor signals receives, evaluates and optionally unlocks the motor current of the electric Sperrwerkmotors. As an alternative to the motor, however, a motor / gear unit, a linear motor, a solenoid, a shape memory element or any other device can be used, which converts electrical energy into motion. With the activation of the engine, the locking mechanism is released, whereby the vehicle door opens. In addition to the control module, an electrical switching element is arranged in the circuit of the motor, which is actuated directly or by means of mechanical or electrical aids from the inside door handle and / or the outside door handle. This switching element is preferably a switch, reed switch, Hall sensor, buttons, relays or other switching element that interrupts the motor power line in the rest position.
  • To open the door, a signal is generated by the operation of the outside door or door handle and passed into the control module, which unlocks the motor current. At the same time, the electrical switching element is switched by the operation of the door inside or outside door handle, thereby closing the motor circuit, so that the locking mechanism opens the vehicle door.
  • Now generates the control module a false signal to open the barrier, a current to the motor is not possible because the motor power line is interrupted by the electrical switching element.
  • If the electrical switching element is a two-pole switch, a signal can be generated via a pole, which is evaluated by the control module and to use the signal for the motor current release. This signal can be generated by a current with a common signal voltage and a common signal current that is interrupted when switching the two-pole switch. The interruption of the signal current takes place by switching over the two-pole switch. This interruption detects the control module and switches, u. U. also taking into account other signals, the motor current freely. Switching the switch closes the motor circuit so that the motor current released by the control module flows.

  • 1 shows the circuit diagram of the motor vehicle door according to the invention with a pawl motor 11 , which drives a non-illustrated pawl of a motor vehicle lock. The pawl motor 11 is through the line 14 with pin 9 of the control module 12 connected. The second motor cable 15 goes to the electrical switching element 13 , which is designed as a closing button.
  • The second pole of the electrical switching element 13 is over lead 17 with pin 3 of the control module 12 connected. Both inside door handle 18 as well as outside door handle 19 actuate the electrical switching element 13 over the lever 20 , This can be the lever 20 consist of several elements, including a lever chain. The inside door handle 18 and the outside door handle 19 are shown schematically by an arrow. Again, it may be a juxtaposition of different mechanical elements.
  • When operating the inside door handle 18 or outside door handle 19 is via switching elements, not shown, a signal to the control module 12 given the pawl motor 11 energized. At the same time, when the inside door handle is actuated 18 or outside door handle 19 the closer 13 transferred to the closed position (see 2 ). Thus, the motor current from pin 9 through the motor 11 and buttons 13 to flow to pin 3 of the control module, whereby the lifting of the pawl takes place.
  • Switches the control module 12 due to a false signal, the motor current, without the button 13 over the inside door handle 18 or outside door handle 19 was placed in a closed position (see 1 ), the circuit between pin 9 and pin 3 is due to the position of the button 13 interrupted, so that the circuit of the pawl motor is not closed and thus the pawl is not excavated.
  • 3 shows the circuit diagram of the motor vehicle lock according to the invention, in which the electrical switching element 13 both the opening signal for the control module 12 generated, as well as the circuit for the pawl motor 11 closes. The pawl motor 11 is through the line 14 with pin 9 of the control module 12 connected. The second motor cable 15 goes to pole b of the electrical switching element 13 , which is designed as mechanically operable changeover switch. Pol a of the electrical switching element 13 is over lead 16 with pin 2 of the control module 12 connected. The feed takes place via Pol c on the electrical switching element 13 that by means of the wire 17 with pin 3 of the control module 12 connected is. Both inside door handle 18 as well as outside door handle 19 actuate the electrical switching element 13 over the lever 20 ,
  • In the rest position flows via pin 2 of the control module 12 a signal current of about 5 to 50 mV at about 4 V-14 V. Usually, a signal current of 10 mA at a voltage of 5 V is used. But since between Pol c of the electrical switching element 13 and pin 3 of the control module 12 also the drive current of the pawl motor 11 flows, a signal current of 12 V can also be used. The use of 4V or 14V is possible because pin 3 is grounded. The signal current can be switched on continuously, pulsed or only after a wake-up process of the control module. In the unactuated state, the signal current flows through pole a and pole c of the electrical switching element 13 to pin 3 of the control module.
  • When operating the inside operating lever 18 or the external operating lever 19 will the signal current, as in 4 shown, interrupted between pin 2 and pin 3 of the control module. At the same time, the pole c and the pole b of the electrical switching element 13 contacted. The control module detects the interruption of the signal current and switches via pin 9 of the control module 12 the pawl motor current. The pawl motor current now flows from pin 9 to the pawl motor and is across pole b and pole c of the electrical switching element 13 on pin 3 of the control module 12 passed, which lies on earth. In this case, the pawl of the motor vehicle lock is dug, whereby the vehicle door opens. Thereafter, the electrical switching element falls in the rest position according to 3 back. Typical ratchet motor currents are between 2 A and 8 A at a voltage of 12 V. A current of about 5 A at 12 V is preferred.
  • 5 shows a further variant of the previously described switching schemes. In this variant, the inside door handle acts 18 or the outside door handle 19 independently of each other on the electrical switching element 13 , The levers or lever chains required for this are in 5 through the contours 21 indicated schematically.
  • According to the wiring diagram, as in 6 is shown, a closing aid can be controlled in addition to the pawl motor. A closing aid moves a motor vehicle door by motor from the pre-catch to the main catch. Since this process involves the risk of pinching body parts and objects, the closing process must be interruptible. The interruption is made by pulling the outside door handle 18 or inside door handle 19 activated. During the closing process, there is an interval when the pawl is in the main catch and the closing aid moves the rotary latch into the overstroke. In order to finish the Einkemmvorgang in this Zuziehintervall, the Zuziehhilfemotor must be de-energized. At the same time, the pawl must be brought into the open position. For this the following actions are necessary:
    Since the Zuziehhilfvororgang is a closing operation, there is the electrical switching element 13 at rest. At rest, the pawl motor 11 not energized and via the poles c and a, a signal current flows. At the same time the closing aid motor 22 energized via pin 7 and pin 8 of the control module. The control module 12 knows that the closing process is taking place. To interrupt the closing process must be on the inside door handle 18 or at the outside door handle 19 to be pulled. In this process, the electrical switching element switches from pole a to pole b. The signal current is interrupted. This recognizes the control module 12 and turns on the closing aid motor 22 de-energized. Simultaneous time activates the control module 12 via pin 9 the pawl motor. The motor current flows due to the drawn inside door handle 18 or outside door handle 19 via the pole c and the pole b to pin 3 of the control module 12 , The pawl thus moves in the open position.
  • 7 shows a variant in which the door inner handle 18 an electrical switching element 13A and inside door handle 19 a second electrical switching element 13B assigned. In the 7 schematically illustrated mechanical connection of the electrical switching elements 13A and 13B was already mentioned in the notes to 5 described. In rest position flows for the inside door handle 18 a signal current via pin 1 of the control module 12 , across Pol a and Pol c of the electrical switching element 13A and continue on the lines 17A and 17B to ground on pin 3. Is by pressing the inside door handle 18 the electrical switching element 13A switched over, so that Pol c and Pol a are interrupted, the Pol c and Pol a contacted, however, recognizes the control module 12 the signal change on pin 1 and switches the pawl motor current to pin 9. The pawl motor current now flows via line 14 , the pawl motor 11 , the lead 15A , over Pol b and Pol c of the electrical switching element 13A , over the line 17A and 17B to ground on pin 3 of the control module 12 , The behavior of the circuit diagram in the event of a faulty disconnection on pin 9 has already been explained in the explanations 1 and 2 explained. That the wires 17A and 17B Both signal currents and pawl motor currents must be forwarded in the description of 3 explained.
  • Will now the outside door handle 19 actuated, interrupts the electrical switching element 13B the signal current between pin 2 and pin 3 of the control module 12 , As a result, the pawl motor current is switched to pin 9. The pawl motor current flows via line 14 , the engine 11 , over the line 15B , the electrical switching element 13B and the line 17B to pin 3. If the pawl supply is faulty through the control module 12 the pawl motor is running 11 not because the circuit without actuation of the electrical switching element 13 through the outside door handle 19 is interrupted (see description of 1 and 2 ). The mutual diverting of the signal current and the pawl motor current via the line 17B was in the description of 3 already explained.
