Definitions

  • the invention relates to a circuit arrangement for driving a displaceable component in a motor vehicle, in particular a motor vehicle window, with the features of the preamble of claim 1.
  • the relay winding lies in a circuit which is closed when the ignition is switched on. Then the window can be opened or closed by pressing the operating switch, while opening or closing the window is not possible when the ignition is switched off.
  • the switching arrangement known from GB-A-1 163 389 it is also possible to operate the window or windows even with the door open by providing a door contact switch which closes the circuit of the relay winding when the door is open.
  • the battery will discharge overnight due to the current consumption of the relay winding if the door is accidentally not fully closed.
  • the invention has for its object to provide a circuit arrangement, on the one hand, opening or closing a motor vehicle window or another displaceable component, for example a sliding roof, with the vehicle door open or, depending on the legal provisions, until the driver's door is opened or the driver's door is open for reclosing the same even when the ignition is switched off, but on the other hand has such a low quiescent current consumption that if the door is accidentally left open, the battery cannot discharge and undesirable heat generation and high energy consumption are avoided even when the ignition is switched on.
  • the circuit of the relay winding is only closed when either the ignition is switched on or the door contact is actuated and at the same time the or an operating switch is switched on. Without actuation of the operating switch, only a quiescent current of less than 1 mA flows and, when using CMOS components, a quiescent current of a few A, so that no appreciable heat development can occur, the power consumption is minimal and also occurs with a circuit with closed door contact with the vehicle door open Discharging the battery is excluded.
  • M1 and M2 denote the motors of two motor vehicle windows which are equipped for clockwise and anti-clockwise rotation and, depending on the direction of rotation, open or close the associated window when an operating switch S1 or S2 is actuated accordingly.
  • Switches S1 and S2 are drawn as simple break switches for simplicity, although changeover switches are used in practice due to the need to reverse the polarity of the motors.
  • the operating switches S1 and S2 are in series with a relay contact R, which is connected to the positive pole of the vehicle battery. When the relay contact R is closed, the motor M1 can be switched on by actuating the switch S1 and the motor M2 can be switched on by actuating the switch S2 and the associated window can be moved accordingly.
  • the relay winding RW is connected on the one hand to the positive line 10 and on the other hand can be connected via a line 12 to a ground line 14 if certain conditions exist, namely a closed door contact switch TK (i.e. open vehicle door) or a closed ignition switch ZS and at the same time at least one closed operating switch S1 or S2.
  • a transistor T1 is arranged in line 12, the base of which is connected via a line 16 to a resistor 18 to the output of a first comparator 20.
  • the non-inverting input of this comparator 20 is connected via a diode 32 to the output of a second comparator 22.
  • the inverting input of the first comparator 20 can be connected to ground on the one hand via a line 24 and the door contact switch TK and on the other hand via a transistor T2 controlled by the ignition switch ZS.
  • the inverting input of the first comparator 20 is connected directly to ground, while when the ignition is switched on, the base of the transistor T2 receives voltage and turns on the transistor T2 and thereby connects the inverting input of the first comparator 20 to the ground line 24.
  • the inverting input of the first comparator 20 is also connected to the positive line 10 via a resistor 26.
  • the resistor 26 serves as a load resistor for the transistor T2 and prevents a short circuit when the door contact switch TK is closed.
  • the inverting input of the second compa rators 22 is connected via a line 28 to the positive line 10a between the relay contact R and the operating switches S1 and S2.
  • the branches 10 and 10a of the positive line are also connected to one another by a high-resistance resistor 30, which is designed such that the motor M1 or M2 does not run when the operating switch S1 or S2 is closed, but the comparator 22 is connected to the positive line 10.
  • the non-inverting input of the second comparator 22 is connected to the positive line 10 via a resistor 34 and to the ground line 14 via a diode 40.
  • the non-inverting input of the first comparator 20 is connected to the ground line 14 by an RC element consisting of the capacitor 36 and the resistor 38.
  • the diode 32 prevents the capacitor 36 from being able to discharge via the second comparator 22.
  • the circuit shown in FIG. 2 differs from the circuit shown in FIG. 1 essentially only in that the base of the transistor T 2 can be connected either to the voltage source (+) or to ground by means of an information memory M in the form of a flip-flop .
  • the flip-flop is set when the ignition switch ZS is closed and thus the base of the transistor T 2 is connected to the voltage source, so that the motors M, and M 2 can be switched on by operating the operating switches S, and S 2 . If the ignition switch ZS is now opened, i.e. the ignition is switched off, the flip-flop remains set and the transistor T 2 is conductive, so that current flows through the relay winding RW in the manner described above in connection with FIG. 1 when one of the Operating switch S l , S 2 is operated.
  • the door contact switch TK is closed, as a result of which the information memory M is erased and the base of the transistor T 2 is connected to ground. So that the transistor T 2 is blocked, which, as also described above, has the consequence that the circuit of the relay winding RW is interrupted and the relay contact R is opened, so that none of the motors M i , M 2 by actuating the associated operating switch S, or S 2 can be turned on. This is only possible again when the ignition switch ZS is closed, which only sets the flip-flop again. As in the circuit according to FIG. 1, only a small operating current flows even when the ignition switch ZS is closed or the door contact switch TK is closed, as long as none of the operating switches is actuated.
  • the motor M, or M 2 can be switched on by actuating its operating switch S, or S 2 , as long as a vehicle door is open, but that such switching on may no longer be possible if the relevant one Door is closed again.
  • the information memory M is designed so that it remains set after setting by closing the ignition switch ZS even after opening the ignition switch ZS and after opening the door, that is to say closing the door contact switch TK, and only after the door has been closed again by opening of the door contact switch TK is deleted, so that the transistor T 2 blocks and thus the circuit of the relay winding RW through the transistor T, even when an operating switch S, or S 2 is no longer activated can be closed. Rather, this is only possible again when the ignition switch ZS is closed.
