Definitions

  • the invention relates to an electric accelerator pedal for motor vehicles, with a setpoint generator, from which an electronic setpoint signal can be fed to an electronic controller unit, with an actuator which can be controlled by electrical signals from the controller unit and is adjustable in a maximum possible setpoint setting range limited by a first and a second end position , by means of which an adjusting device for controlling the motor power can be actuated electromechanically via a transmission unit in an actual setting range within the target setting range limited by a first and a second end position.
  • Such an electric accelerator pedal is known (DE-A-27 14 113). If such a motor is installed in a motor vehicle or if parts, in particular mechanical transmission parts, are exchanged on an already installed unit, manual adjustment of the entire unit is always necessary due to the manufacturing tolerances. This also applies if there is no longer an optimal setting due to changes in the game after long driving. This adjustment is very labor-intensive and costly.
  • a device for detecting the most closed position of the throttle valve of an internal combustion engine in which the most closed position of the throttle valve is detected and stored each time the accelerator pedal is released, if the detected signal value is smaller or is equal to the previously stored signal value. In this way, the throttle valve angle that is constantly changing during the warm-up phase of an internal combustion engine is taken into account when determining the idle operating state.
  • variable delivery limit stop for an injection pump of a diesel engine which according to the respective operating variables, for example boost pressure, engine temperature, outside temperature, Maximum delivery rate limited.
  • a spiral cam disk is adjusted by means of a microcomputer starting from a fixed starting position in defined steps by means of a stepping motor.
  • the position of the actuating signal is determined by a detection and setting device which is arranged in the motor vehicle and is connected to the setpoint generator and the electronic control unit and can be switched on by the ignition switch of the motor vehicle can be detected and the area between the two end positions can be stored as an effective target setting area in the controller unit.
  • the adjustment device which is permanently arranged in the motor vehicle and is connected to the setpoint generator and the electrical control unit and can be switched on by the ignition switch, automatically makes an adjustment during each starting process, which can be completed within one to two seconds and makes any mechanical adjustment work completely unnecessary.
  • the adjustment device can be brought into the idle position after the adjustment process.
  • the actuator is only in its idle position adjusted before effective control from the setpoint generator can take place.
  • the switch-on of the adjusting device can preferably be blocked during engine operation.
  • the controllability of the electronic controller unit can be blocked by the setpoint generator during the setting time.
  • the switchability of the starter for the motor of the motor vehicle can preferably be blocked during the adjustment time.
  • FIG. 1 there is a setpoint generator 1 designed as a potentiometer, which can be adjusted by an accelerator pedal 2.
  • An electrical setpoint signal can be fed from the setpoint generator 1 to an electronic controller unit 3.
  • the controller unit 3 controls an actuator 4, by means of which an adjusting device for controlling the motor power can be mechanically actuated via a transmission unit 5.
  • the adjusting device is a throttle valve 6.
  • the throttle valve 6 is in an actual setting range pivotable, the first end position of which is defined by a stop 7 and the second end position of which is determined by a stop 8.
  • the pivot lever 9 of the actuator 4, which drives the transmission unit 5, can be adjusted between a first and a second end position I and II, which are shown by the dash-dotted lines, in a desired setting range.
  • the maximum possible setting range is greater than the actual setting range of the throttle valve 6.
  • This actual setting range is shown with broken lines both on the throttle valve 6 and on the swivel lever 9.
  • the target setting range of the pivot lever 9 shown by the dash-dotted lines is so large that even taking into account all possible tolerances on the pivot lever 9, transmission unit 5, throttle valve 6 and the stops 7 and 8, the pivot range of the pivot lever 9 represented by the broken line is always within of the target setting range shown in broken lines.
  • FIG. 1 there is also an ignition switch 10 and an adjusting device 11 enclosed by a broken line.
  • One input of an AND element 12 can be connected to the positive pole 13 of a battery via the ignition switch 10.
  • the second input of the AND gate 12 is negated and connected to an engine speed sensor 14. If the engine speed is 0, a signal is applied to the AND gate 12 from the engine speed sensor 14 due to the negation. If the ignition switch 10 is also closed, the AND element 12 emits an output signal which is fed to a timing element 15.
  • the timer 15 controls a further timer 16 and a control unit 17 for a lower response time a.
  • a position controller 18 of the actuator 4 is then actuated by the control unit 17 and drives the drive 19 of the actuator 4 in the direction of its first end position I.
  • the time element 16 driven by the timing element 15 transmits a signal to a pulse counter 20 only after the expiry of an adjustment time b, which corresponds at least to the maximum adjustment time required for adjusting the actuator 4 from the second end division II to the first end position I.
  • the frequency of its pulses is converted into a voltage in a frequency / voltage converter 21 and stored in a correction memory 22.
  • the correction memory 22 then forwards its storage value to an adder 23.
  • a further value is fed to this adder 23 and added to the stored value.
  • This further value is supplied by a position indicator 24 of the actuator 4 and corresponds to the distance from the second end position II to the position into which the actuator 4 can be moved closest to the first end position I.
  • This total value is stored as a fixed value in a fixed value memory 25 and is present at one input of a comparator 26. If the output value of the adder 23 present at the second input of the comparator reaches the value of the read-only memory 25, the comparator 26 emits a signal.
  • This signal acts on the pulse counter 20 and stops it.
  • the final memory value of the correction memory 22 is thus also fixed and is supplied by the latter via a connection 49 to the electronic controller unit 3 and stored there as the lower end position of the effective setpoint adjustment range.
  • the output signal of the comparator 26 is also fed to an input of an AND gate 27.
  • a second negated input of the AND gate 27 is connected to the output of a comparator 28, which has the same function as the comparator 26 and does not yet emit a signal at this time.
  • the output of the timing element 15 is connected to a third negated input of the AND element 27.
  • the timing element 15 After the setting time a, the timing element 15 no longer emits a signal, so that then no signals are present at the two negated inputs of the AND element 27 and a signal is present from the comparator 26.
  • the AND gate 27 emits a signal and sets a timer 29 for a response time a 'in motion.
  • a control unit 30 and a timer 31 are connected to the timer 29.
  • the control unit 30 then controls the position controller 18 of the actuator 4, which drives the drive 19 of the actuator 4 in the direction of its second end position II.
  • the timer 31 By negating its output, the timer 31 outputs an output signal to a pulse counter 32 in the same way as the timer 16 only after an adjustment time b '.
  • This pulse counter 32, a correction memory 34 adjoining it via a frequency / voltage converter 33 and an adder 35 work with a read-only memory 36 and the comparator 28 in the same way as pulse counter 20, frequency / voltage converter 21, correction memory 22, adder 23, read-only memory 25 and comparator 26.
  • the value determined at the correction memory 34 is fed via the connection 37 to the electronic controller unit 3 and is stored there as the upper end position of the effective target setting range.
  • the output signal of the comparator 28 stops but not only the pulse counter 32, but also acts on the one negated input of the AND gate 27, so that it is blocked. Furthermore, the output signal of the comparator 28 is also present at an input of an AND gate 38.
  • a second input of the AND gate 38 is connected to the output of the AND gate 12, a third negated input to the output of the timing element 15 and a fourth likewise negated input to the output of the timing element 29.
  • a timer 39 is actuated by this.
  • the timer 39 gives a signal to a control unit 40, the output 41 of which controls the positioner in such a way that the actuator 4 moves into its lower end position determined by the correction memory 22. This position corresponds to the idle position of setpoint generator 1.
  • the output signal of the timing element 39 continues to apply an input to an AND element 42.
  • the second input of the AND element 42 is connected to the ignition switch 10 and is thus subjected to a signal.
  • the output signal of the timing element 39 likewise emits a signal from the AND element 42 and feeds it to a timing element 43, the input of which is negated.
  • the timer 43 does not emit an output signal for a reset time e ".
  • This reset time e " is shorter than the start time e '. But it is so long that the actuator 4 has definitely moved into the lower end position before it expires.
  • the timer 43 gives a signal to a starter lock switch 44.
  • the starter lock switch 44 receives a further signal from an engine speed sensor 45 at a speed of 0 and switches a starter 46 of the engine upon presentation of these two signals so that it is started .
  • the starter switch 44 receives a signal of an existing engine speed from the engine speed sensor 45 and switches off the starter 46.
  • An input of an AND element 47 is also acted upon by the output signal of the timing element 43.
  • the signal from the setpoint generator 1 present and previously blocked at the second input of the AND element 47 is thus fed to the electronic controller unit 3 via the output of the AND element 47.
  • the effective setpoint adjustment range is stored in the controller unit, which corresponds exactly to the actual adjustment range actually present on the drive 19 of the adjustment device for controlling the motor power.
  • the system of the electric accelerator pedal is thus readjusted with every starting process. A separate manual adjustment when installing such a system is no longer necessary.
  • the position of the actuator 9 of the electric accelerator pedal from FIG. 1 is plotted over time in a diagram in FIG. It can be seen from this that after closing the ignition switch 10, the setting time a for determining the lower limit of the effective target setting range of the controller unit 3 and the setting time b begin. During the adjustment time b, the actuator 9 is moved from any initial position towards its first end position I. After the adjustment time b, the counting process is carried out on the pulse counter 20 during the effective payment time c. A subsequent safety time d ensures that the counting process is completed with certainty before the setting time a for determining the upper limit of the effective target setting range of the controller unit 3 begins. In principle, the procedure is the same.
  • the actuator 9 moves from its lowermost possible position to the end position I into the position closest to the end position II.
  • the adjustment time b ' there is again a counting time c', while the counting process takes place on the pulse counter 32, and a safety time d'an.
  • both the reset time e "and the start time e' begin to run.
  • the actuator moves back to its lowest position next to the end position I, so that during the subsequent starting process the actuator does not move in one Full throttle position.
