Definitions

  • the invention relates to a keyless engine start authorization control device for motor vehicles with a transceiver device assigned to the motor vehicle, comprising an evaluation unit for carrying out a question and answer dialog requesting the driver authorization, with a mobile identification transmitter and with a start unit for manually starting and stopping the Motor and to effect a mechanical unlocking and locking of the rotary movement of the steering wheel.
  • Keyless engine start authorization control devices are known and are used in motor vehicles to increase the operational security and the ease of use.
  • Such an engine start authorization control device comprises a transceiver device arranged on the motor vehicle for carrying out a communication between the transceiver device and the ID transmitter requesting the authorization of an identification transmitter (ID transmitter) carried by a user. Communication takes place on a radio link. If it is recognized on the system side that there is an authorized ID transmitter inside the motor vehicle, an actuating device is released, with which the steering wheel is then mechanically unlocked and the desired engine start is triggered.

  • a starting device referred to as an ignition starter switch
  • the starting unit of the engine start authorization control device known from this document is permanently installed in the motor vehicle and comprises an actuator which is designed as a push-turn knob in order to bring about an engine start and an unlocking of the steering wheel.
  • the rotary pushbutton comprises a button for triggering the dialog requesting the driving authorization between the motor vehicle transceiver and the mobile identification transmitter.
  • Engine start authorization control device can be carried out in a simple and very functional manner a driving authorization query, starting the engine and unlocking the steering spindle with a valid identification transmitter present in the motor vehicle interior.
  • actuation of the rotary pushbutton to start the engine and to unlock the steering spindle is not possible as intended, if an authorized identification transmitter is not recognized in the motor vehicle interior. Even if this is fundamentally intended, situations can occur in which it is nevertheless desirable to unlock the starting unit or start the engine and / or unlock the steering spindle.
  • the invention is therefore based on the object of developing a generic keyless engine authorization control device mentioned at the outset in such a way that it is fundamentally possible to move the motor vehicle even in the described emergencies.
  • the starting unit itself has a transceiver coil connected to the transceiver unit for carrying out a short-range authorization query and a receptacle for receiving an emergency key containing a transponder, so that a driving authorization query between the transmitter -Receiving coil and the transponder of the emergency key can be carried out if this is inserted in the receiving unit.
  • the keyless engine authorization control device has a starting unit which is itself equipped with a transmitting / receiving coil for carrying out a driving authorization query.
  • This transmit-receive coil is unlike the others Transmitters and receivers of the transceiver are only designed to carry out a short-range authorization query.
  • the starting unit further comprises a receptacle for receiving an emergency key.
  • the emergency key contains a transponder, so that after inserting the emergency key into the receiving unit, an authorization query can be carried out between the transmitting and receiving coil of the starting unit and the transponder of the emergency key.
  • the reception of the starting unit thus serves to bring the transponder contained in the emergency key into the transmission-reception area of the transmission-reception coil.
  • a mechanical key with a corresponding transponder can in principle be used as the emergency key, which is also used as a key or as an emergency key for opening the doors of the motor vehicle.

If the rotary pushbutton contains a slot for receiving the emergency key, the transponder contained in the emergency key is brought into the immediate vicinity of the transmitting and receiving coil by inserting the emergency key into this slot.
  • the push knob as an actuator of such a starting unit forms a physical unit with a tongue-like actuator.
  • This tongue-like actuator engages through a latch locking device, the latching force of which must be overcome by pressing in the push-button and which basically prevents the push-button from being pulled off.
  • the push-button together with its actuator can be pulled out of the starting unit, so that this push-button can then be replaced by a mechanical emergency key containing the transponder.
  • the locking of the starting unit expediently works together with an asymmetrical locking recess of the tongue-like actuator of the push-button.
  • the asymmetrical design of the latching recess is provided in order to counter a certain counterpressure against a pushing-in movement of the push-turn knob, by means of which movement also the execution of the driving authorization check is triggered.
  • the asymmetrical locking recess acts in the other direction to prevent the push button from being pulled out when normal tensile forces are present. When a predetermined tensile force is exceeded, however, the detent is also moved out of the recess, so that the push-button with its tongue-like actuator can then be pulled out of the starting unit to make room for the transponder-containing mechanical emergency key.

  • a locking device with a locking bolt acts on the receptacle in such a way that after the receptacle has been moved out of its starting position to start the engine, a return of the receptacle to the starting position is fundamentally prevented.
  • the locking device can be actuated to unlock the return movement of the receptacle, unlocking takes place when a control command that is independent of actuation of the receptacle is present, for example when the system side of an automatic vehicle it has been determined that the gear selector lever is in the park position. So that in the case of system errors, in which an unlocking of the restoring movement of the receptacle is no longer possible, such as to effect a steering spindle lock, the receptacle has a stop that can be overcome with a predetermined force, against which the locking bolt of the locking device after actuation the receptacle to start the engine and to lock the reset in its original position.

  • the catch tumbler 13 engages with its upper bar in the catch recess 14.
  • the latching recess 14 is asymmetrical, the flank of the latching recess facing the push-button being designed to be inclined to the push-button 3. To cause the push-button 3 to be pressed in, the resistance provided by the spring-loaded latch lock 13 and the inclined flank must first be overcome before the push-button 3 can be brought into the position pressed in in FIG. 2 with its actuator 4.
  • the other flank of the recess 14 is approximately at right angles or only slightly inclined away from the rotary pushbutton 3 educated.
  • This rear flank of the catch recess 14 thus represents an effective resistance so that the push-button 3 with its actuator 4 cannot be pulled out of the receptacle 5.
  • this is not fundamentally prevented by the engagement of the upper bar of the latch locking device 13 in the latching recess 14. Rather, the push knob 3 together with its actuator 4 can also be pulled out of the receptacle 5 by applying a corresponding tensile force.
