Definitions

  • the invention relates to a control device for locking and / or unlocking a safety device, in particular a motor vehicle locking device, with a transmission device supplied by a power source, which has a code generator for generating coded information stored in it and a radiator of the coded information, with a from a second power source receiving device having receiving means for receiving the encoded information, a memory in which the encoded information is stored, and a comparator for comparing the received information with the stored information, the receiving device in the event of the match of this information a control signal can be output to the safety device.
  • Control devices of this type are known in particular as door locking of motor vehicle doors and already have a high level of security against unauthorized opening of the motor vehicle doors.
  • the object of the invention is to provide a control device according to the preamble, which prevents unauthorized unlocking of the safety device with high security.
  • the receiver device has a signal generator for generating further coded information and the further coded information can be stored in the memory of the receiver device and can be emitted by a transmitter of the receiver device, and in that the transmitter device encodes a receiver for receiving the further coded information Has information and the further coded information can be stored in the memory of the transmitting device while deleting the first coded information.
  • This configuration allows the coded information to be changed as often as desired, so that even if the coded information is recorded, a later unauthorized opening of the security device is prevented if a recoding has been carried out.
  • the transcoding process of both the receiver device and the transmitter device takes place automatically after it has been initiated.
  • the signal generator is preferably an oscillator connected to the receiver device. Absolute security against a reconstruction of the recoded information is achieved in that a random pulse sequence can be generated by the oscillator.
  • control device can be constructed with an extremely small space requirement, which is particularly important when used in motor vehicles, since there is only little installation space available there.
  • the generation, transmission and storage of the further coded information can preferably be switched on by a switch of the receiver device.
  • the transmitter can be switched on by a switch. To ensure that the information broadcast is always safe and full are constantly received, the transmission of the first coded information by the transmitter device and / or the transmission of the further coded information by the receiver device takes place in a multiple interval.
  • the power source of the receiver device is preferably the battery of the motor vehicle.
  • the transmitter device can be location-independent of the receiver device and is preferably arranged in an ignition key of the motor vehicle. This is easily possible when using a microprocessor, without the construction volume being significantly larger than with conventional ignition keys. In addition to the ignition key, there is no need for the driver to carry any other parts with him.
  • the power source of the transmitter device is a DC power source, e.g. As a cell, it can be easily accommodated in an ignition key and is easily replaceable by the driver.
  • the receiver device has a second transmitter, from which information can be emitted after the control signal of the receiver device has been sent to the safety device, and if the information of the second transmitter can be recorded by a receiver of the transmitter device and a signal device can be controlled by the receiver, the operator is always on Signal given when the receiver device has actually correctly captured the encoded information.
  • the signal device is preferably a tone generator. Such a signal device is advantageous when used on motor vehicle doors, since no operating noises occur with today's door locks are heard and thus the operator does not know after actuation of the transmitting device whether the safety device has actually been activated.
  • first and second transmitters are infrared elements.
  • the emitter and / or the first transmitter and / or the second transmitter can be a light-emitting diode.
  • the receiving means and / or the first receiver and / or the second receiver are preferably a phototransistor.
  • control device described can be used both to initiate an opening process and to initiate a closing process. However, it is also possible that an unchangeable code signal is used for the closing process.
  • a particular advantage of the control device is that it is not necessary to already enter coded information. Coding is carried out solely by switching on the receiver device for generating and transmitting and storing the coded information, and thereby storing coded information both itself and the transmitting device. Thus, only identical structural units are required for the transmitter device as well as for the receiver device, which means an exchange as well as the bearing considerably simplified and cheaper. If, for example, an ignition key provided with a transmitter device is lost, only a new ignition key needs to be coded by actuating the ignition switch.
  • the control device shown has a transmitting device 1 and a receiving device 2.
  • the receiver device 2 can be arranged in a motor vehicle for controlling a motor vehicle locking device and the transmission device can be arranged in an ignition key of the motor vehicle.
  • the transmission device 1 has a microprocessor 3, which is connected to a quartz crystal 4, a tone generator 5 and a switch 6 designed as a push-button switch for switching on the transmission device 1.
  • the power supply is provided by a direct current source 7.
  • An output 8 of the microprocessor 3 leads via an amplifier 9 to a light-emitting diode forming an emitter 10.
  • a receiver 11 formed by a phototransistor is connected via an amplifier 12 to a coding input 13 of the microprocessor 3. Furthermore, the receiver 11 is also connected to an activation input 14 of the microprocessor 3. This activation input 14 can also be controlled by the switch 6 via a diode 15.
  • the receiver device 2 also has a microprocessor 16 with a quartz crystal 17.
  • the microprocessor 16 is connected to the power source of the motor vehicle (terminal 30) via the connection 18.
  • the connection 19 is connected to the ignition switch (terminal 15) of the motor vehicle, so that the microprocessor 16 is actuated each time the vehicle is started.
  • the inputs 20 of the microprocessor 16 are each assigned to a locking device arranged in a door of the motor vehicle and can be used by mechanical actuation by means of a key to control the microprocessor 16 if the normal function of the control device is disturbed.
  • An oscillator 22 generating a random pulse sequence is connected to a further input 21 of the microprocessor 16.
  • a transmitter 24 formed by a light-emitting diode is connected to an output of the microprocessor 16 via an amplifier 23.
  • another transmitter 26, which is formed by a light-emitting diode is also connected to an output of the microprocessor 16 via an amplifier 25.
  • Receiving means 27 formed by a phototransistor are connected via an amplifier 28 to an input of the microprocessor 16.
  • Each of the three outputs 29 of the microprocessor 16 leads to a locking device for the central locking of the motor vehicle and transmits the control signal emitted by the microprocessor 16.
  • the function of the Steuerv Q rtreu ' is as follows.
  • the microprocessor 3 of the transmitting device 1, which is normally not activated, is acted upon by closing the switch 6 both via the diode 15 with an activation signal and also controlled to emit the coded information stored in it via the emitter 10.
  • This coded information is received by the receiving means 27 of the receiver device 2 and is increasingly supplied to the microprocessor 16.
  • the comparator contained in the microprocessor 16 compares the received information with the coded information stored in the memory of the microprocessor 16. If the received information matches the stored information, the microprocessor 16 outputs an acknowledgment information via the amplifier, which is emitted by the transmitter 24.
  • the microprocessor 16 emits a control signal via the outputs 29, by means of which the locking devices (not shown) are controlled in the opening or closing direction.
  • the microprocessor 3 controls the tone generator 5 to emit a tone. This tone shows the operator that the entire control process was carried out properly.
  • the microprocessor 16 is controlled via the connection 19 in such a way that a random pulse sequence is fed to it from the oscillator 22, which the microprocessor 16 stores in its memory while deleting the previously stored coded information.
  • this random pulse sequence is fed via the amplifier 25 to the transmitter 26, which emits this coded information.
  • This new coded E information is received by the receiver 11 of the transmitting device 1, which thereby both activates the microprocessor 3 and also feeds the coded information to the microprocessor 3 via the amplifier 13. This now stores the new coded information by deleting the previously stored coded information.
  • the microprocessor 3 is only activated when it is actually performing a function, the power consumption of the transmitting device is kept very low.
