Definitions

  • the invention relates generically to a control device for a door lock arrangement on a motor vehicle, of which at least one door lock has an electromotive mechanism with a servo motor, which controls itself automatically with the aid of an operating control device after activation in the sense of a locking movement or opening movement.
  • a motor vehicle door lock which is set up accordingly, is for. B. described in DE-A-31 50 620.
  • the servomotor has the task of facilitating or closing or closing the motor vehicle door equipped with such a door lock.
  • the operational control device is generally not constructed electronically.
  • the known generic control device from which the invention is based does not always meet all requirements in terms of safety. It is particularly disturbing that an unintentional opening of this motor vehicle door is possible almost without power and happens when a switch of the operating control device is actuated by mistake. It also bothers that. B. by children playing, an actuation of the servo motor until destruction by overload is possible. It cannot be ruled out that if a car door is closed carelessly, a person gets stuck because for example, it gets between the door and door rebate with your fingers, but the servomotor continues its locking movement. Garments can also be pinched in this way.
  • Another control device (GB-A-21 29 044) lacks an electromotive mechanism and an associated servomotor.
  • a door lock arrangement is known (EP-A-01 47 549), which has a servo motor and a discriminator assigned to the servo motor, which is intended to arrange time intervals during the passage of the actuator between different switching points, so that the working speed of the servo motor can then be set up so that that the parts thereby moved reach their end position without running in hard.
  • the invention has for its object to further develop a generic control device so that an unintentional opening of the motor vehicle door while the motor vehicle is moving is no longer possible and actuation of the servo motor is ruled out until it is destroyed.
  • an electronic safety switching device superordinate to the operation control device which has at least one travel sensor and an associated switch, and that the travel sensor switches off the operation control device via the assigned switch when the motor vehicle exceeds a predetermined speed
  • the servo motor has an electronic counting device which counts up an actuation time of the servo motor and which counts the pause time down to zero, and wherein the counting device takes the operating control device out of operation when a predetermined value of the upward counting is reached.
  • the travel sensor is designed as a wheel sensor. It can be combined with the wheel sensor of an anti-lock braking system or at the same time be designed as such. However, there is also the option of designing the travel sensor as a speedometer sensor.
  • the safety switching device also includes a Has emergency switch with which the servomotor can be switched to the opening movement during the locking movement. It is understood that such an emergency switch is expediently located in a door in the area of the motor vehicle door lock. Within the scope of the invention it can also be achieved without difficulty that the servomotor is not damaged by overloading. To this end, the invention teaches that the safety switching device further comprises a servo motor protection switch which detects the temperature of the servo motor, and that the servo motor protection switch takes the operation control device out of operation when the determined temperature exceeds a predetermined maximum temperature. There are various ways of determining the maximum temperature.
  • a preferred embodiment which is of particular importance because of its functional reliability, works with the counting device which, when a predetermined value of the up-counting is reached, actuates the servomotor circuit breaker which deactivates the operation control device. But you can also work with a thermal sensor, which is arranged during operation of the servo motor.
  • the electronic safety switching device can be constructed in a known manner so that it controls itself: after the electronic circuits of the safety switching device are supplied with voltage, the functional sequence is released. All memories are deleted or brought to a defined content. A self-test then runs in test mode, which checks all parameters and functional parts to be tested. The status determined in this way is compared with a normal state stored in a permanent memory.
  • the safety switching device has a stand-by circuit which switches on with the last actuation command from the operating control device or when the maximum temperature is reached, and that the stand-by circuit queries all functions .
  • a control device can be installed in a motor vehicle in which only one of the doors is equipped with a door lock which has an electromotive mechanism and a servo motor. In general, however, several door locks are set up accordingly. In the embodiment with a plurality of door locks, each with an electromotive mechanism plus a servo motor, the invention teaches that a central safety switching device is provided for this plurality of door locks and that this is wired to all door locks via control lines and load lines.
  • the electronic safety switching device as a central switching block for this plurality of door locks has in which the travel sensor with the assigned switch and possibly the stand-by circuit and possibly the device for switching the closing movement into an opening movement when an emergency switch is housed, but that the other functional parts of the safety switching device in separate switching blocks in the area the door locks are arranged.
  • the operating control device can also be constructed electronically or largely electronically and can be integrated into the electronic safety switching device according to the invention. It goes without saying that the electronic safety switching device is equipped with corresponding display devices which allow the driver of the motor vehicle to check the door lock arrangement and its various functional positions.
  • FIG. 1 shows a door lock 1 which belongs to a door lock arrangement on a motor vehicle.
  • This door lock 1 has an electronically operated mechanism 2 with a servo motor 3, which controls itself automatically with the aid of an operating control device 4 in the sense of a locking movement or an opening movement.
  • an electronic safety switching device 5 which is higher than the operation control device 4 is additionally provided. 2 and 3, the special design of the safety switching device 5 can be seen. It has at least one travel sensor 6 and is characterized in that the travel sensor 6 switches off the operating control device 4 via the assigned switch when the motor vehicle reaches a predetermined travel speed exceeds.
  • the circuit is further made such that the servo motor 3 has an electronic counting device 7 which counts up the actuation time of the servo motor 3 and which counts the pause time down to zero.
  • the counting device 7 takes the operation control device 4 out of operation when a predetermined value of the up-count is reached.
  • the travel sensor 6 can be designed as a wheel sensor or speedometer sensor.
  • the safety switching device 5 also has an emergency switch 8 with which the servo motor 3 can be switched to the opening movement during the locking movement.
  • the safety switching device 5 also has a servo motor circuit breaker 9 which determines the temperature of the servo motor 3, wherein the servo motor protection switch 9 takes the operation control device 4 out of operation when the determined temperature exceeds a predetermined maximum temperature.
  • the servomotor circuit breaker 9 can be provided with a temperature sensor 10.
  • FIGS. 2 and 3 also show the stand-by circuit 11 of the function already described, which therefore switches on with the last actuation command from the operating control device 4 or when the predetermined maximum temperature has been reached and polls all functions.
  • Fig. 2 shows that the safety switching device 5 can be designed as a central unit that operates the various door locks. As central electronics, it can be integrated in an on-board computer or can be associated with it. But it is also possible to implement decentralized electronics, as it were. This was shown in FIG. 3.
  • the safety switching device 5 is here divided into two blocks, as it were. With the registered and already explained reference numerals, the embodiment of FIG. 3 is otherwise easily understandable. It is understood that in the control device according to the invention a special component for switching on or connecting to the power supply is provided, which was not shown and belongs to the safety switching device 5. Otherwise, the safety switching device 5 is provided with a status or error display 12. Locking and unlocking can be operated as usual via a corresponding component 13.
