Definitions

  • the invention relates to a method for switching several circuits of a vehicle and a switch therefor.
  • Switching methods of this type and the switches are used in vehicle technology to control multiple circuits and their associated consumers in the vehicle electrical system.
  • the switching contacts of a multi-position switch are electrically connected directly to the circuits to be switched.
  • the different lighting conditions - parking light, driving light, fog light, rear fog light and possibly high beam are switched directly via a single multiple switch.
  • the switch contacts Due to the sometimes powerful consumers, such as the driving lights, the switch contacts have to be used to switch high outputs - or higher ones
  • the present invention is therefore based on the object of providing a method for switching a plurality of circuits in a vehicle, which enables the use of inexpensive switches which are simple to manufacture.
  • the circuits of the consumers are no longer controlled directly, but indirectly by means of binary coding of the positions of an actuating element by means of switching elements, for example microswitches, which do not have to switch high powers.
  • the binary coding enables the use of inexpensive logic components such as gate or processor logic, which in turn the circuits via known low-loss inexpensive electrical switching or control elements
  • Such logic can consist, for example, of a possibly programmable gate (logic array) or processor logic.
  • logic modules can be easily exchangeable on or in the switch, at least in the manufacturing process.
  • binary coding of a switch or the position of its actuating element can be fed via a bus system to a central logic (on-board computer) which can also be responsible for controlling further on-board functions.
  • the number of coding possibilities is greater than the number of positions of the actuating element or the desired switching states. This excess number of coding options can then be used to check (redundancy) the positions of the actuating element or an individual specific circuit function.
  • a switching element (redundancy switch) is additionally determined in the position by the actuating element via the profile disk
  • Redundancy switch other redundant principles are applied.
  • the switching elements or microswitches or pushbuttons can be actuated via the profile disk in such a way that each coding combination differs a neighboring (for example 0000, 0011, 0101, 1000, etc.) or even any other in at least two bits (for example 0000, 1001, IIIO. Olli, etc.).
  • the respective permitted combination or change can then be checked by logic and, in the event of malfunction - in the case of double redundancy - intervene in a corrective manner and / or trigger an alarm.
  • FIG. 1 is a perspective view of a rotary light switch according to the invention for a vehicle
  • Fig. 2 is an enlarged view of the lower portion of a rotary light switch shown in Fig. 1;
  • FIG. 3 shows a plan view of a circuit board of a rotary light switch
  • Fig. 4 is a perspective view of Fig. 3 and
  • Fig. 5 is a schematic representation of the switching positions of a rotary light switch.
  • the rotary light switch 1 shown in FIG. 1 has on its upper side a button 3 which can be actuated by an operator and which is removably rigidly attached to an end 5 of an axis 5 protruding from a housing 2.
  • the axis 5 is rotatably and longitudinally displaceable in the top and bottom of the housing 2.
  • a board 9 is arranged in the middle in the housing, the axis 5 extending vertically through a central recess in the board 9.
  • this central recess is larger in its internal dimensions than the external dimensions of the axis section penetrating through it.
  • a profiled disk 7 is arranged on the axis 5 in a rotationally fixed and longitudinally displaceable manner.
  • the profiled disc 7 has a central recess in the form of an internal hexagon, which corresponds to the dimensions of the external hexagon region of this section of the axis 5 or is of slightly larger design.
  • the axis 5 is in the form of a hollow cylindrical body which is fixedly arranged with the housing 1 or its underside
  • Bearing sleeve 8 rotatably and longitudinally mounted.
  • the upper side (end face) of this sleeve 8 serves as a lower, fixed limit stop for the underside of the profiled disk 7, the upper side of which comes into contact with the contacts of the microswitches 11 to 14 or is acted upon by a spring force from these.
  • the profile plate 7 is in spite of the longitudinal displaceability of the axis 5
  • the limit when the axis 5 is pulled out via the button 3 by an operator is shown in a manner not shown by recesses and projections on the axis 5 and hereby interacting elements fixedly arranged on the housing.
  • the axis 5 can only be pushed in until the bottom of the button 3 rests on the outside of the top of the housing 5.
  • the profile disk 7 has on its upper side in the direction of the board 9 a profile consisting of projections and recesses, which serves to actuate the microswitches 11 to 14.
  • the microswitches 11 to 13 can be arranged tangentially as in FIGS. 1 and 2 or in the radial direction as in FIGS. 3 and 4.
  • the arrangement of the switches 1 1 to 14 corresponds to the profile of the profile plate 7 and the desired switching characteristics of the switches 11 to 14.
  • switch 14 functions as a redundancy switch, which ensures a particularly important one Function - such as the driving or dipped headlights here - contributes despite the malfunction.
  • the "driving lights” function is also secured by a "0" position (i.e. driving lights active) of switch 14.
  • the "0" position (driving lights active) corresponds to the behavior “switch not actuated” or “no current” or line to ground ", so that the driving lights are connected via a logic circuit by means of an OR operation with the 3-bit code for driving lights (in example 01 1) remains switched on, thereby recognizing a potential malfunction as such and can even be output as an alarm "malfunction".
  • redundancy switches of this type can also be used in combination with one another, so that both malfunctions can be detected and / or switched in a fault-tolerant manner.
  • the binary coding of switch positions of a multiple switch is not limited to 3-bit coding with an additional redundancy switch, but depending on the number of switch positions required, it can be implemented as multi-bit coding with one or even more redundancy switches (e.g. for several safety-relevant switching functions).
  • the switching method according to the invention enables an inexpensive, simple construction of such a switch with binary coding by means of a microswitch for weak outputs and possible redundancy.
  • the redundancy can also be achieved by special
  • Coding levels e.g. Change of at least two states per level or redundancy bits for checksums etc. can be implemented.
  • the circuits are then controlled via control electronics with a logic unit and switching unit, which can be accommodated in part or in total in or on the switch.
  • This control electronics can advantageously be designed as part of a central control, such as an on-board computer.
  • a central control such as an on-board computer.
  • microswitches 1 1 to 14 as can be seen from FIGS. 3 and 4, there are further microswitches 15 and 16 on the circuit board 9 directed to axis 5.
  • these switches 15 and 16 serve to detect a two-stage pulling out or pushing in of the axis 5 and corresponding switching functions such as fog light and / or rear fog light.
  • latching curves or elements are arranged in the switch 1 in a manner not shown in more detail, which ensure the latching position in the conventional manner in the rotational and longitudinal directions.

Abstract

Cette invention concerne un procédé de commutation de plusieurs circuits, notamment des circuits de dispositif d'éclairage, dans un véhicule automobile. Selon ce procédé, on code plusieurs positions d'un élément de commande en binaire et on réalise le codage binaire d'une logique qui commande la commutation des circuits. Cette invention concerne également un commutateur conçu afin de mettre en oeuvre ce procédé. Ce commutateur comprend un élément de commande et un dispositif de commutation, ce qui permet d'obtenir plusieurs états de commutation en fonction de la position de l'élément de commande. Le dispositif de commutation est composé de plusieurs éléments de commutation présentant chacun deux états de commutation. On obtient ainsi un codage binaire des états de commutation de tous les éléments de commutation en fonction de la position de l'élément de commande, ce qui permet, par l'intermédiaire d'une logique, de commuter les circuits.
