Definitions

  • the invention relates to a control for a throttle valve according to the preamble of claim 1.
  • a generic device is known from DE-OS 40 31 003.
  • a control for a throttle valve in which the drive for an engine control unit is used to adjust the idle position of the throttle valve.
  • the potentiometer assigned to this motor control part measures accordingly thus a swiveling of a partial area of the possible total swiveling the throttle valve.
  • the drive provided in this internal state of the art for an engine control part is used to set the idle position of the throttle valve. That this The correspondingly assigned motor control part therefore measures a potentiometer Swiveling only a part of the possible total swiveling the throttle valve shaft.
  • a potentiometer switch is known, which is used for recording of the throttle valve angle is used.
  • the potentiometer has three side by side arranged resistance tracks of different lengths. With help of a Switch is chosen between these three resistance tracks. Such Potentiometer switching is very complex and expensive.
  • the object of the invention is to reduce this effort.
  • the Electronics only the actual value sensor is exchanged in such a way that a sensor,
  • a potentiometer is used, which as before on the Adjustment path that is roughly assigned to the idle control range can, maintains the previous values while over the remaining travel of the potentiometer its resistance value does not change and, accordingly, none Has influenced.
  • the potentiometer is short-circuited.
  • the figure shows a schematic representation of the structure of a throttle valve control.
  • a cable 12 is mechanically actuated via an accelerator pedal 10.
  • the cable 12 moves when the accelerator pedal is depressed into that indicated by arrow 14 Direction.
  • an actuator 16 is counter to an action by a spring 24, which is fixed to a stationary part 26, moved in the direction of this arrow.
  • the actuator 16 has a stop lug 18 which, when not depressed Accelerator pedal 10 comes into contact with a first stop 20 and on the other hand prevents the deflection by the accelerator pedal at a stop 22.
  • the minimum deflection corresponds
  • the stop 22, which corresponds to the maximum deflection is the Adjustment path of the accelerator pedal and the mechanical adjustment path of the throttle valve.
  • the mechanical connection 12 uses an electrical connection which depressing the accelerator pedal in a corresponding shift of the Actuator 30 implements.
  • a driver 28 of the actuator 16 presses an actuator 30, the rigid with a throttle valve 36 that opens or closes a passage 34, connected.
  • the actuator is in the direction of the minimum opening Throttle valve 36 is pulled by a spring 32, which on the fixed part 26th is stored.
  • an actuator 40 acts as a part on the actuator 30 an electromechanical control system that also has a driver press the actuator 30 in the opening direction of the throttle valve 36 can.
  • the motor control part 40 can be driven, for example by a drive 44 Electric motor operated, which moves a gear 46 on a rack 42 works and thus the rack and the rigidly connected to it Motor control can move.
  • Stops 48 and 50 are also assigned to the motor control part, the stop 48 limits the movement in the closing direction of the throttle valve and sets one Idle stop represents the stop 50 limits the movement of the engine control 40 in the opening direction of the throttle valve 36.
  • the Stop 50 positioned so that it the maximum position of the opening in Limited idle case.
  • the Stop 50 arranged such that it the maximum opening of the throttle valve limited at full load.
  • An evaluation electronics 56 is provided to control the drive 44 Information among other things from two actual value sensors, which are in the present Traps designed as potentiometers 52 and 54 are supplied.
  • the Potentiometer 52 detects the actual position value of the actuator 30, the potentiometer 54 detects the position of the motor control part 40.
  • the evaluation electronics 56 supplies the information to the via a line 58 Drive 44, and drive 44 is driven to in the schematic Representation in the figure, the motor control part 40 to the right or left for position control to move the throttle valve 36.
  • the minimum opening of the engine control element and thus the throttle valve 36 is through the stop 48 specified, so that mechanical jamming prevents this by closing the throttle valve too far or a appropriate jamming of the drive elements could occur.
  • a stop 50 limits the maximum deflection, the can Throttle valve 36 cannot be opened by the drive 44. Another Opening of the throttle valve 36 in the known device can only by depressing the accelerator pedal 10 happen.
  • the potentiometer 52 which is the total travel of the throttle valve must scan, set to a trajectory of 90 °.
  • the potentiometer 54 which is assigned to the motor control element 40, measures accordingly approximately only a maximum swivel range of 25 °, above furthermore, the stop 38 comes out of contact with the motor control part 40, which Motor control part 40 cannot be opened any further.
  • potentiometer 54 is able to resolve relatively accurately and accurately Information about the evaluation electronics 54 and the line 58 to the Forward drive 54 to perform the position control of the throttle valve 36.
  • the potentiometer 54 must now have a control range of Cover 90 ° and supplies 40 other values for the position of the motor control element the evaluation electronics 56. It is therefore necessary to use vehicles with cruise control to be equipped with a different evaluation electronics 56 than Vehicles without cruise control. Also the potentiometer 54 must be interpreted differently, since vehicles in which the drive 44th only the idle control takes over, the first 25 ° must measure exactly, while vehicles with cruise control other potentiometers received because the throttle valve angle of about 90 ° must be resolved.
  • the potentiometer 54 is designed that on the one hand no electrically different potentiometers are necessary and on the other hand also maintain the evaluation electronics 56 unchanged can be.
  • the potentiometer 54 corresponds to its resistance value the position of the motor actuator 40 changes over the range in which an idle setting takes place.
  • the movement of the motor control part 40 in practice a swiveling, becomes transferred to the wiper of the potentiometer 54 and the resultant Resistance value is queried via evaluation electronics 56.
  • the design of the potentiometer 56 is now designed so that that over about 25 ° pivoting angle of the motor actuator 40, the resistance value changes, preferably linearly from 0 to its maximum value, and that a further pivoting between about 25 ° and 90 ° to none Change or at most a negligible change in the resistance value of the potentiometer 54 leads.
  • the first area is Idle control area assigned.
  • potentiometer 54 can be the same in both embodiments Perform tasks, and the evaluation electronics 56 need not be changed will.
  • potentiometer 54 is such that the functionless way the resistance path is simply short-circuited, so that a further sliding of the grinder on the resistance track the measured Resistance does not change.
