Definitions

  • the present invention relates to a centralized control device for the openings of a motor vehicle. It is intended to control door locks, the trunk and other protected access devices such as the fuel filler flap, the glove compartment, etc.
  • the control of locking or unlocking of these various openings or access is centralized, that is to say that it can be controlled by actuating the key by the lock of one of the front doors or of the boot, by a remote control, or by an anti-aggression button.
  • Double-acting or triple-acting door locks exist in the state of the art.
  • Document DE-A-3 541 995 describes a lock comprising a double-acting actuator, that is to say a locking effect and an unlocking effect, which is connected to a control unit by three conductors, two of which are used in power transfer and in information transfer.
  • the so-called triple effect door locks have two locking states, a first "locking" state in which the door is locked and a second "deadlock” state which corresponds to a locking mode in which the lock is hookable and can only be unlocked electrically.
  • This central control unit can also receive a "condemnation" or "unlocking" signal transmitted by a remote control made from outside the vehicle, or by an anti-aggression button.
  • an alarm device warning the driver that one of the protected accesses is poorly closed and visually designating the access that is poorly closed.
  • the indication of poor closing is provided by a contactor which is most often in the lock, called a C.P.O contactor with the door open.
  • the invention therefore aims to create a centralized control device for the doors of a motor vehicle which makes it possible to significantly reduce the number of conductors necessary for the connection between the doors and the central control unit.
  • the subject of the invention is a centralized control device for the openings of a motor vehicle, in which the openings comprise a triple-acting electric actuator, comprising at least one electric motor, and certain openings include a mechanical control device with key lock supplying orders to a central control unit defining an actuator actuation sequence, the central control unit also receiving orders coming in particular from the ignition key and / or from a remote control device, and / or an anti-aggression button (as described in document FR-A-2,524,050), and is characterized in that the central control unit is connected to each of the opening elements by a single line with three conductors sometimes used for power transfer, sometimes for at least two of them, for order information transfer, in that in each opening, the actuator is permanently connected between the three conductors of said line and in that the central control unit comprises means for selectively applying to each of said conductors the voltages necessary for the execution of a sequence.
  • a series of electronic components passive voltage level fixing is connected between two contactless conductors in the rest position.
  • Any command to "lock” or “unlock” with the key defines a position of said key which closes the circuit by means of one or more of the aforementioned components and the two conductors, one polarized at the positive voltage of the source via a resistor, the other connected to ground.
  • the central unit comprises a voltage level detector taken at the terminal of the resistor adjoining the components; this detector supplies control signals to the means for applying the polarities corresponding to the demand to the three conductors.
  • the two front doors 2 are equipped with a key lock 7 which is equipped with electrical contacts supplying electrical signals to the central control unit 1 with a view to "unlocking", “locking” or “locking” "openings.
  • Figure 2 is the electrical diagram of the circuit contained in an opening such as a front door.
  • This circuit essentially comprises three conductors 11, 12, 13 each connected to one of the conductors of line 8 (control by the key can take place between 11 and 12 for example).
  • Each opening comprises an electric actuator with triple effect, for example two DC motors M1 and M2; the motor M1 controls the “locking” or the “unlocking” of the opening and the motor M2 controls the "deadlocking” or the “unlocking” of the lock.
  • the door In the "deadlocking" position, the door cannot be opened using the mechanical control elements of the door, lever or push-button, but only by an electric control provided by the introduction of a coded key in the lock 7 or by a remote command received by the detector 6.
  • the motors M1 and M2 are permanently connected between the three conductors 11, 12 and 13.
  • the motor M1 is connected between the conductor 13 and the conductor 12.
  • the second motor M2 is also connected between the conductors 13 and 12.
  • a diode D1 separates the terminals arriving from the motors M1 and M2, the cathode of D1 is connected to M2.
  • the terminal of M2 which is connected to the conductor 12 is extended on the conductor 11 by a diode D2, the cathode of which is connected to this conductor 11.
  • the control takes place between the conductors 11 and 12.
  • Zener diodes 14 connected in series in the example shown. From the anodes of these Zener, we define three terminals for a switch.
  • the other conductor 12 is connected to the common terminal of a three-position switch 15 via a diode 16, the cathode of which is connected to the conductor 12.
  • the role of the diode 16 is to avoid the passage of 'a power current through the Zener diodes if a key request occurs during a power transfer for a "deadlock".
  • This three-position switch is in fact constituted by the coded key introduced into the latch 7; the three possible positions of the lock key 15 correspond to the three aforementioned states, "unlocking", “locking” and “deadlocking". This switch closes a circuit through one or more Zener diodes as required.
  • a resonant circuit consisting of a coil 17 and a capacitor 18 is connected between the two conductors 11 and 12 with the interposition of a contact 19 corresponding to the open door contactor CPO and which is closed when the door is opened or not closed properly.
  • the electrical circuit integrated in the other openings such as the rear doors or the tailgate does not include the elements 14 to 16 corresponding to the key lock 7.
  • Figure 3 shows in a simplified way the circuit of the central control unit.
  • Line 8 is connected to three inputs 21, 22 and 23 which correspond respectively to conductors 11, 12 and 13 of each of the openings. Each of these inputs is connected to the contact of a control relay respectively B1, B2 and B3 which are shown in the idle state.
  • the coils of relays B1, B2 and B3 are controlled by a microprocessor 20 as will be described in detail below.
  • the terminal 23 which corresponds to the conductor 33 of the line 8 and the terminal 22 which corresponds to the conductor 32 of the line 8 are connected to the negative terminal 24 of the supply battery of the vehicle.

  • the terminal 21 which corresponds to the conductor 31 of the line 8 is connected to the negative terminal 24 of the battery. In the rest position, terminal 21 is connected to a measurement detector 26 which supplies information to the microprocessor 20. This terminal 21 is biased at the positive voltage by a resistor 10 which is connected to the conductor 21 via the rest contact 27 of relay B1 and the working contact of a switch 30 'controlled by actuation of the ignition key.
  • the rest contact 27 of the relay B1 can also be connected to an alternating current generator 28 either by means of plug cicuits connected in series or by means of a resistor in which case the string of plug circuits can be placed in parallel between 12 and 13, or deleted.
  • Each of these plug circuits is tuned to the resonant frequency of the resonant circuit 17, 18 of one of the openings.
  • An alarm device, such as a warning light 29, is connected in parallel to each of the resonant circuits.
  • This indicator can for example be constituted by a light-emitting diode.
  • the activation of the generator 28 is controlled by a signal from the closing of a contact 30 which is closed by the vehicle ignition key and which corresponds to the circuit 5 of FIG. 1.
  • the microprocessor 20 also receives information from contact 30 on the insertion of the vehicle ignition key. It also receives information via an anti-aggression contact 34 which can be closed by the user when the latter is in the vehicle. Finally, the microprocessor 20 receives an order of "condemnation", “super-lock” or “unlocking” supplied by means of a contact 35 associated with the remote control detector 6.
  • FIG. 4 is a detailed diagram representing the detector circuit 26.
  • the signal from the measurement conductor 31 is sent to three operational amplifiers 41, 42 and 43 which, on the other hand, each receive a setpoint adapted to the voltages of the Zener diodes. 14.
  • these reference signals are respectively equal to 2, 4 and 6 Volts.
  • the signal supplied by the first operational amplifier 41 is sent to an AND gate 44 with three inputs, the other two inputs of which receive a voltage. positive corresponding to logic state 1.
  • the output of the AND logic gate 44 is sent to a monostable flip-flop 45, the output of which provides a first command signal.
  • the output of the second operational amplifier is sent on an AND logic circuit 46 with three inputs; the second input of this circuit receives the output signal from the operational amplifier 43 and the third input of this circuit receives the inverted output signal from the comparator 41, the inversion being carried out by an inverting gate 47.
  • the output of this circuit AND logic 46 controls a second monostable flip-flop 48, the output of which also provides an order signal.
  • the output of the operational amplifier 43 is sent on an AND logic circuit 49 with three inputs, the other two inputs of which receive respectively the inverted output signal from the operational amplifier 41 and the inverted output signal from the operational amplifier 42 by through an inverting gate 51.
  • the output of the AND logic circuit 49 controls a third monostable flip-flop 52, the output of which also provides an order signal.
  • FIG. 5 is a diagram showing the detail of the generator 28. It essentially consists of four flip-flops 61, 62, 63 and 64 which are connected in series so as to constitute a ring counter;
  • FIG. 6 is a timing diagram representing respectively the clock signal sent on each of the flip-flops and their output Q.
  • the output signal Q of each of the flip-flops controls a transistor 65 which constitutes a switch arranged between the DC voltage source and the supply wire of each periodic signal generator 71, 72, 73 and 74.
  • the output of each of these generators is sent to the conductor 36 of Figure 3 upstream of the plug circuits.
  • the frequencies of the signals supplied by the generators 71 to 74 correspond respectively to the resonant frequencies of each of the resonant circuit assemblies 17, 18 of the door circuit and of the corresponding plug circuit of the central control unit.
  • the voltage read by the detector 26 is the voltage of the battery which is sent from the terminal 25 through the resistor 10.
  • the door key If the door key is actuated to obtain "locking", it is the position corresponding to two diodes 14 in series which is obtained and the two comparators 42 and 43 pass to the logic state "1"; the inverter 51 blocks the AND gate 49 and only the gate 46 goes to the logic state "1", which activates the flip-flop 48 which controls the supply of the coil of the relay B3. It follows that the motor M1 is supplied in the opposite direction to that of the "unlocking". The motor M2 is not activated taking into account the fact that its two terminals are connected to the same positive potential of the power supply and that D1 opposes the passage of current, towards 32.
  • the diodes D1 and D2 make it possible to isolate or select M2 according to the polarities applied to the three conductors, this authorizing it to be put to rest during a simple "condemnation" request where M1 alone is activated.
  • the lowest Zener voltage has priority, which determines a priority in the case of two different simultaneous key requests.
  • it is the request for "deadlock” corresponding to the lowest Zener voltage which has priority over the other orders. It is the same for the command of "condemnation” which has priority before a command of "unlocking". This is a choice that can be changed at will. One frees oneself in this way, as well as by protections on the monostable rockers of the emission of two different simultaneous orders.
  • the Zener diodes 14 can be replaced by other electronic components dividing a voltage applied across the two conductors.
  • the microprocessor 20 can also be controlled by the remote control shown diagrammatically by the contact 35 which provides "unlocking” or "condemnation” information to the microprocessor 20.
  • the device according to the invention also comprises an anti-aggression device shown diagrammatically by the contact 34 which is actuated by the occupant of the vehicle when he is inside of it and which also transmits order information. "condemnation" to the microprocessor 20.
  • the microprocessor 20 also receives information relating to the vehicle ignition key (contact 30).
  • the information provided by the actuation of the ignition key of the vehicle authorizes the actuation of the anti-aggression device and inhibits the remote control.
  • actuation of the vehicle ignition key controls the procedure for monitoring the door contacts by activating the generator 28 which therefore only works when the ignition key is in the active position. In this position, the positive DC voltage applied to the control conductor 21 is suppressed, which is then subjected to the periodic signals supplied by the generator 28.
  • monitoring is interrupted for a short time by the microprocessor 20 so as to honor the order.
  • the door closing status is monitored using only two conductors, namely conductors 31-32.
  • the generator supplies a series of pulses of different frequencies which correspond respectively to the resonant frequencies of the pairs of resonant circuit-plug circuit of the central control unit and of each door.
  • the current flows through the two conductors 11 and 12, there is a drop in impedance of the resonant circuit at the resonance frequency of the door considered, and it follows that the voltage across the corresponding plug circuit of the central control unit takes a high value, which activates the alarm constituted for example by the indicator 29 which flashes according to the cyclic frequency of the generator 28.
  • the generator 28 supplies a complex voltage of several equal voltages whose frequencies correspond to the frequencies of the resonant circuits.
  • a summing circuit to send the set of frequencies to the conductor 11.
  • the four signal generators are continuously supplied, the ring counter is no longer used.
  • only a single frequency generator is provided in the central control unit and, in each door, the series resonant circuit is replaced by a vibrator operating at the frequency supplied by the generator of the central control unit.
  • This variant makes it possible to limit the size of the dashboard by numerous indicators. It is however possible to provide a single indicator constituting a permanent alarm while the operation of the buzzer is delayed and the audible signal stops after a certain time.
  • a capacitor can be arranged in series with each of the vibrators. With the door closed improperly indicated in the door itself, the occupants' attention is drawn much faster, especially when it comes to rear doors.
  • the plug circuits are eliminated, and the generator 28 permanently sends cyclic trains of periodic waves of different frequencies. These signals pass through a resistor located in series with the generator 28 in the central unit. With the impedance presented by the resonant circuits, this resistance plays the role of a voltage divider bridge: at its terminal adjoining the conductor 21, the amplitude of each of the signals passing through it is looked at. In the absence of a door that is not closed properly, the amplitude of the signal at the cited terminal is that of the signal emitted by the generator 28. As soon as a door contact 19 closes, this amplitude falls like a voltage divider bridge for the signal at the resonant frequency of the door not closed properly.
  • the series of plug circuits in parallel between the two conductors 21 and 22 in the central unit, that is to say between the output 36 of the generator connected to the conductor 21, and the minus polarity of the battery connected to conductor 22.
  • the generator 28 permanently sends cyclically the periodic wave trains at the different frequencies, through a resistor.
  • each plug circuit On reception of its own frequency each plug circuit has a high impedance. As soon as the door contact 19 of the corresponding resonant circuit is closed, the impedance across said plug circuit drops, the same goes for the voltage across its terminals. An alarm is triggered as soon as this voltage drop is detected.
  • the invention makes it possible, by using only three connecting conductors forming a bus between the central control unit and each of the opening elements, to centrally control the opening, "locking" and even “deadlocking" of the doors. and send from each of the doors, the necessary orders provided by the door key.
  • Another advantage of the invention lies in the fact that only passive elements are housed in the doors, which is important from the point of view of cost and reliability.
  • two of these conductors are sufficient to carry out monitoring of the closing state. of all the openings, indicating each time that the door is not closed properly.
