Definitions
- the present invention relates to a method for learning the rest position of the accelerator pedal of a motor vehicle.
- the accelerator pedal of a motor vehicle By pressing the accelerator pedal of a motor vehicle whose movement is determined.
- the degree of depression of the accelerator pedal, and on the output signal from the accelerator pedal, for example, the injection rate of an injection system is controlled.
- the accelerator pedal sensor When the accelerator pedal is not actuated, the accelerator pedal sensor normally outputs a zero signal, which corresponds, for example, to idling operation of the vehicle.
- the accelerator pedal sensor outputs a signal or accelerator pedal tension that is greater than zero, even though the accelerator pedal is not depressed, this will result in deactivation of monitoring mechanisms so that unexpected accelerations can not be detected and avoided. This can lead to problems.
- Deviations of an electrical nature are, for example, intermittent shunt resistances or short circuits.
- Deviations of a mechanical kind can for example be based on the fact that the accelerator pedal, for example due to material fatigue (springs, etc.), does not completely return to the rest position (starting position).
- a learning technique has been developed to reduce the output value (pedal voltage). of the accelerator pedal sensor corresponding to the depression degree of the accelerator pedal from zero (rest position of the accelerator pedal) to a more appropriate value corresponding to the actual rest position.
- the lowest measured pedal tension in each drive cycle was used for each pedal track to determine the idle position of the accelerator pedal for the remainder of the drive cycle.
- a transfer between different drive cycles did not take place.
- a certain robustness was achieved by disregarding the starting phase, ie the learning process only became active a certain time after starting the motor vehicle.
- the invention has for its object to provide a method for learning the rest position of the accelerator pedal of a motor vehicle, which is characterized by a particularly high robustness.
- the determination of the lowest pedal value corresponding to the rest position of the accelerator pedal based not on the lowest measured voltage, but on the lowest voltage, which is constant over a certain time and repeated several times in the drive cycle. This constant lowest pedal voltage over a certain period is confirmed in at least one subsequent drive cycle, and a lowest pedal value is set based on this voltage and finally confirmed.
- the plausibility check is preferably used to distinguish between electrical and mechanical drift.
- the invention further relates to a device for learning the rest position of the accelerator pedal, comprising the following components:
- the means for the plausibility check is preferably used to distinguish between an electrical and a mechanical drift.
- the means for confirming and setting a lowest pedal value preferably confirms the lowest pedal voltage in a plurality of subsequent different drive cycles.
- FIG. 1 is a diagram showing the course of the pedal clamping tion and corresponding deviation possibilities from the nominal state
- FIG. 2 is a block diagram showing the main steps of the method according to the invention.
- Figure 3 is a diagram showing the determination of the lowest pedal voltage
- Figure 4 is a diagram showing the determination of the lowest pedal voltage in different drive cycles.
- the mechanical accelerator pedal movement is reproduced in percent on the abscissa, while the corresponding pedal voltage (sensor voltage) is shown in volts on the ordinate.
- the dashed line 1 shows the course of the pedal voltage as a function of the pedal movement.
- the dashed lines 2 represent the maximum or minimum curve of the pedal voltage at maximum production tolerance.
- the crossed line 4 shows the possible course of the pedal voltage at the end of the life.
- a first step 8 the lowest pedal voltage is determined during a first drive cycle, whereby this lowest pedal voltage voltage must be constant over a certain period of time and must be repeated several times within the drive cycle.
- the confirmation and setting of the lowest pedal value takes place during at least one subsequent drive cycle, which is preferably a plurality of subsequent different drive cycles.
- a plausibility check of the confirmed lowest pedal value is carried out with the aid of a further pedal sensor.
- step 11 the stored value is stored. According to step 12, the method described above can be repeated after a longer driving time of the motor vehicle.
- the abscissa represents the time and the ordinate the pedal voltage in V.
- the course of the pedal voltage is shown during a first drive cycle.
- 13 indicates the lowest pedal voltage during the first drive cycle, which must be constant over a certain period of time according to the specification. With 16 in this case a case is shown, in which the lowest pedal voltage does not meet the corresponding condition due to insufficient duration.
- the pedal voltage is shown in the various drive cycles.
- the first drive cycle is indicated by “0”, and several consecutive different drive cycles are indicated by “1-N.”
- the pedal voltage indicated at "14" satisfies the appropriate conditions.
- "The pedal voltage shown at” 15 "does not meet these conditions due to temperature effects or mechanical blockages therefore out of the dashed line indicated area. If the number of confirmed drive cycles (here all cycles except cycles 5 and 7) is greater than the number of required cycles (setpoint), the subsequent plausibility check of the confirmed lowest pedal value is performed using another pedal sensor. If this is not the case, for example, the corresponding limit values can be slightly changed, and it can be checked again whether the lowest pedal value can be determined and confirmed often enough.
