Definitions

  • the invention relates to a vehicle anti-jamming device for preventing jamming of foreign bodies, in particular endangered body parts of vehicle occupants, by motor-adjustable vehicle parts.
  • Such safety devices are known in different construction.
  • a sensor is provided in the form of an arranged at the closing edge of the opening electrode extending over the length of the closing edge and part of a capacitive Detector is that emits a threatening clamping a control signal to turn off the drive of the closing member.
  • Clamping devices of this type are exposed to influences that have nothing to do with a risk of entrapment and can cause false tripping.
  • influences include, in particular, tolerance-related changes in distance and environmental influences such as moisture and precipitation deposits. Attempts have been made to counteract this by continuously or before the start of the movement of the vehicle part, the operating point (that is, the triggering threshold) of the terminal protection device is tracked accordingly.
  • Capacitance changes of the capacitive detector which are caused by the movement of the vehicle part itself, have been roughly corrected in their typical course. Environmental conditions can be effectively compensated and either an increased risk of false triggering tolerated or the sensitivity of the system must be reduced accordingly.
  • the object of the invention is therefore to provide a safety device for vehicles that allows a comparatively low cost secure detection of Einklemmge risk even with changing environmental conditions and the unavoidable in practice tolerances.
  • this object is achieved by a device for preventing jamming for vehicles with at least two sensor arrangements for detecting a risk of being trapped by at least one vehicle part which can be adjusted by means of a drive device and for outputting anti-jamming signals to an evaluation device which is jointly assigned to two sensor arrangements is designed to switch via a drive control, the drive means in a pinch-preventing operation mode, when the pinching danger signals of the two sensor arrangements differ from each other by a predetermined minimum value.
  • the anti-pinch device With the anti-pinch device according to the invention, the fact is used that changing environmental conditions and the proper movement of the or the adjustable Vehicle part / vehicle parts attributable influences on all sensor arrangements substantially the same effect and thus remain unevaluated in the arrangement according to the invention, while hazardous situations typically make different perceived at a time at the sensor assemblies and are detected.
  • the drive device have at least one actuator which is in driving connection with two actuating arrangements which are in each case assigned to one of two opposite sides of one and the same adjustable vehicle part, wherein preferably the two positioning arrangements are at least approximately symmetrical to one another and in each case one of the two sensor arrangements is in each case arranged on one of the two positioning arrangements.
  • the drive device may also have at least two actuators, which are in drive connection with at least two actuating arrangements, which are in each case assigned to one of a plurality of adjustable vehicle parts.
  • the at least one adjustable vehicle part may be designed for selectively closing or at least partially opening a vehicle opening, and the sensor arrangements may in each case have at least one capacitive sensor.
  • the evaluation device is expediently equipped with a comparator for comparing the entrapment danger signals of the sensor arrangements.
  • Fig. 1 is a schematic block diagram of a first embodiment of a clamping protection device according to the invention.
  • FIG. 2 shows a schematic block diagram of a second embodiment of a terminal protection device according to the invention.
  • Fig. 10 is a vehicle part, for example the cover of a sliding / lifting roof, which can be adjusted in the direction of a double arrow 11 by means of adjusting arrangements 12, 13 which engage on opposite sides of the vehicle part 10.
  • the adjusting arrangements 12, 13 are, for example, the usual sliding / dispensing mechanisms on both sides of the lid 10.
  • the adjusting arrangements 12, 13 are in turn actuated by means of a preferably electric actuator 14, which is under the influence of a drive control 15. Closing movements of the lid 10, which could lead to pinching vulnerable body parts are monitored by two sensors 16, 17, of which one 16 of the actuator assembly 12 and the other 17 of the actuator assembly 13 is assigned.
  • an evaluation device 18 is connected, which includes a comparator 19 and a downstream threshold member 20 in the illustrated embodiment.
  • the output of the evaluation device 18 is connected to a control input of the drive control 15.
  • the in Fig. 2 differs from those of FIG. 1 only in that the drive control 15 actuates two actuators 14a and 14b for two simultaneously adjustable vehicle parts 10a and 10b, for example a pair of retractable front-mounted headlamps. Even in such a case, a risk of entrapment typically only occurs on one side, ie either on the vehicle part 10a or the vehicle part 10b, and it becomes clear from the environmental influences and / or concurrent displacement movements of the vehicle parts 10a with the means described above and 10b.
  • any number of further pairs of sensors may be associated with each of the downstream, connected to the drive control 15 evaluation device, as shown in FIG. l is indicated with the blocks 16n, 17n and 18n.
  • the sensors 16 to 16n, 17 to 17n may be arranged in pairs, for example on deployment levers, top hinges and other clamping points. They are preferably designed as capacitive encoders, although basically any other sensors such as inductive, infrared, ultrasonic or Hall sensors come into consideration.
  • the evaluation circuit 18 can also in other than in FIG. 1 schematically indicated way be implemented, for example, using a measuring bridge.
  • the comparison of the output signals of the sensors 16 to 16n, 17 to 17n can be made before - for example by means of a measuring bridge - during (for example with a corresponding transducer) or after - in an evaluation software or a hardware comparator as shown in FIG. 1 indicated at 19 - an appropriate treatment of the sensor measured values done.
  • the described anti-jamming device is characterized in particular by a greatly reduced sensitivity to environmental influences compared to known arrangements with simultaneously preserved or improved sensitivity for actual approximation of body parts to sensors.
  • the anti-jam device can be constructed relatively simple, robust and reliable.

Abstract

L'invention concerne un dispositif anti-serrage destiné à des véhicules et comprenant au moins deux dispositifs détecteurs (16, 16n, 17, 17n) permettant de détecter un risque de serrage par au moins un élément de véhicule (10, 10a, 10b) qui peut être réglé par un dispositif d'entraînement (12, 13, 14, 14a, 14b), et d'émettre des signaux de risque de serrage à un dispositif d'évaluation (18) commun aux deux dispositifs détecteurs. Le dispositif d'évaluation (18) est conçu de telle façon qu'il commute le dispositif d'entraînement en mode de fonctionnement empêchant le serrage à l'aide d'une commande d'entraînement (15) lorsque les signaux de risque de serrage des deux dispositifs détecteurs se distinguent d'une valeur minimale déterminée.
