Definitions
- the invention relates to a central locking device for motor vehicles.
- EP 118 001 is a central locking system for Motor vehicles with a number of actuators arranged in the doors of a motor vehicle (Locking devices) known.
- Each of the actuators has a certain number of Signal transmitters, which depend on the current state parameters of them monitored actuator or depending on externally entered command signals Send signals to a central control unit, the control unit consisting of the signals of the Signal generator forms control signals with which the control elements are controlled, which effect the locking or unlocking of the actuators.
- each actuator is connected to a central device which evaluates the state parameters registered by the signal generators of the actuators.
- the data signals supplied by the signal transmitters are then corresponding to one in the Central device stored program in control signals for the control elements of the Actuators implemented.
- the signal levels of the output signals are the signal generator depending on the detected state of the actuator either to ground or have a predetermined voltage level that is the same for all motor vehicles is. In most cases, this is the level of the vehicle electrical system voltage. This enables a potential burglar by cutting one of the signaling devices with the central device connecting electrical line and connection of the respective Voltage level to open the doors of the motor vehicle and in most cases to deactivate the anti-theft alarm system.
- the invention is therefore based on the object of a central locking device To create motor vehicles where the potential burglar is not able to by simply cut the corresponding signal line to lock the door or the Override central locking device as a whole.
- the output signal of at least one signal generator, depending on the change, the actuators of the actuators are controlled is coded specific to the vehicle and / or door.
- This is preferably the output signal of the signal generator, which reflects the "system open” state. So it is the potential Burglars not possible by simply cutting the electrical connection between the signal generator and the control unit and application of a voltage level (Ground or vehicle electrical system voltage) to open the motor vehicle.
- the output signal is preferably changed via voltage coding.
- voltage coding via a resistance ratio that can be learned by the control device during a first closing operation respectively.
- signal transmitters of the actuators connect different Z diodes.
- the central locking device for a motor vehicle shown in FIG. 1 includes the central locking control of the doors VL, VR, HL and HR.
- the Locking function of a tailgate can be included.
- Each of the doors VL, VR, HL and HR is equipped with an actuator 1 to 4 designed as a door lock, each of the Actuators have a different number of signal transmitters depending on their use in the motor vehicle 5 to 8.
- the signal generators 5a and 7a each send a "system" status signal Open “and the signal generators 5b and 7b" system close ".
- Further signal generators 5c, 5d, 6c, 6d, 7c, 7d and 8c, 8d indicate the state of the respective door and the signal transmitters 5e, 6e, 7e and 8e send a signal indicating whether the anti-theft device is activated.
- the HL doors and HR do not have any door locks 3 and 4 that can be activated by the user. For this The reason for this is that the signaling devices intended for this are missing. All signal transmitters are as Hall sensors or microswitch.
- the output signals of the signal generators 5 to 8 are fed to the central control device 9, which from the output signals, the control signals S1 to S8 to control the Motors M1 to M4 determined.
- the output signals 5a, 5b and 7a, 7b are active Signals, d. H. depending on their change, the control signals S1 to S8 are formed primary, the output signals of the remaining signal generators are only used as status signals considered. A change in these status signals does not trigger the motors M1 to M4.
- the signal transmitters 5a and 7a are door-specific for burglar protection Ohmic resistors R1 and R2 connected downstream.
- the Input resistances R3 and R4 of control unit 9 are determined in accordance with the door become.
- the input resistors R3 and R4 are only for clarity of illustration drawn outwards.
- the output signal 11, 19 of the signal generator 5a, 7a encoded according to the resistance ratio R1, R3 and R2, R4 and the encoded Output signal I1a, I9a transmitted to the control unit.
- the transmitted signal from the encoder 5a, 7a level U 5a, 7a U is thus dependent on the resistors R1, R3 and R2, R4. It will therefore be more difficult for a potential burglar to find the effective level for opening the doors of the motor vehicle when cutting the line carrying the output signals I1a, I9a. Any fluctuations in the electrical system are calculated by the control unit 9 against the resistance ratio R1, R3 and R2, R4.
- FIG. 2 shows both the signal level of the uncoded output signal I1 lying on the vehicle electrical system voltage U BORD and the signal level U 5a of the coded output signal I1a transmitted to the control device 9.
- Another possibility is to encode the output signals 11, 19 of the signal generators 5a and 7a via an electronic circuit, which detects an edge change in the output signal and transmits the edge change in coded form to the central control unit 9, the corresponding signal profiles of the output signal 11 on board voltage U BOARD of the signal generator 5a and the coded output signal I1a are shown in FIG.
- All actuators 1 to 4 also have the signal transmitters 5c, 5d, 6c, 6d, 7c, 7d, 8c, 8d send a status signal indicating whether the door is open or closed.
- the output signals the signal generators 5e, 6e, 7e and 8e indicate whether the anti-theft device is activated.
- the output signals of the signal transmitters are each transmitted to the decentralized control devices 10 to 13, which are also located in the doors and assigned to the individual actuators 1 to 4 and which communicate with the central control device 9 in a time-division multiplex process.
- each decentralized control unit 10 to 13 also receives selected output signals from the signal generators of the other actuators 1 to 4, from which the control units 10 to 13 determine the control signals S1 to S8 for controlling the respective motor M1 to M4.
- the Signal generators 5a and 7a each have the ohmic resistances defined specifically for the door R1 and R2 connected downstream and the input resistors R3 and R4 of the decentralized Control units 10 and 11 vary depending on the door, so that the output signal 11, 19 of the signal transmitter 5a, 7a transmitted as coded output signal I1a, I9a to the respective control device becomes.
