Definitions

  • the invention relates to a method and a device for controlling the operation of an automated clutch arranged in the drive train of a vehicle with a drive motor and a transmission.

  • the shift lever 7 actuates indirectly via a linkage or a Bowden cable or directly via transmission elements a shift shaft 52 which is arranged within the transmission and can be moved axially back and forth and pivoted.
  • the axial back and forth movement of the control shaft 52 corresponds to a selection movement; the pivoting movement corresponds to a switching movement.
  • the selector shaft 52 has a selector finger 54 which protrudes into selector forks 56 which are mounted on the transmission housing in a linearly displaceable manner and can be moved back and forth between two end positions, each end position corresponding to the shifting of a gear.
  • the end position of the shift forks 56 are detected by microswitches 58, of which only the right-hand side is shown in FIG. 2.
  • the selection movement of the switching shaft 52 is detected by a sensor 60 and the switching movement by a sensor 62.
  • the sensor configuration of the gearbox can vary greatly depending on the requirements and the sensors selected.
  • the sensor 37 provided directly in the knob of the shift lever 7 according to FIG. 1, which can respond to a mere touch and / or can detect the actuating force can be completely omitted and replaced by one or more sensors, for example sensors 60 and 62, which detect the movement of the shift lever 7 or the shift shaft 52, wherein a signal can be derived from the movement signal which indicates the actuation speed of the shift lever 7 or the shift shaft 52.
  • the long duration of an intention to shift can be caused by an error in one of the sensors or also in the control unit or by the driver, for example, not switching the shift lever after performing a shift releases and is identified as an intention to shift when a force exerted on the knob of the shift lever exceeds a predetermined value.
  • the period of time that leads to a change in the shift intention can be constant, it can be selected differently from gear to gear and depending on the driving situation. It is advantageous to choose a short period of time for high load requirements by the driver and, for example, to extend it in overrun mode, since experience has shown that the shift lever is actuated very slowly in overrun mode.
  • a threshold value for example the level of force with which the shift lever 7 has to be actuated in order to trigger an intention to shift, can be increased in order in this way to prevent or stop the triggering.
  • t indicates the time.
  • the curve drawn shows how the initially low threshold is gradually increased until it is greater than the actuating force at time 1, so that the intention to switch is deleted. From time 2, the threshold is gradually lowered in order to remain at the setpoint shown in dashed lines.
  • the associated adaptation methods or programs are stored in the control unit 22. Another problem with shift intention identification is as follows:
  • a driver changes his intention to shift, i.e. If he first actuates the shift lever with a predetermined force or by a predetermined distance so that he does not shift after all, and even does this in repeated alternation, this may lead to a brief intention to shift with the associated opening of the clutch.
  • the change in the conditions can consist, for example, in that after identifying closely sequential switching intentions, the switching intent is deleted over a predetermined period of time. It is also possible to monitor the path of the shift lever or another element of the circuit, for example the shift shaft 52, and to suppress a shift intention identification if a certain path has been traveled after (or before) the shift intention.
  • the increase in threshold value can depend on the strength of the strength of the disturbances caused by the road. Furthermore, individual impacts, for example through potholes or thresholds on the road, can be detected in order to make it more difficult to identify the gearshift intention for the short period of time when such faults occur and their after-effects.
  • the detection of a bad road surface is possible in a variety of ways, for example, as described, by sensors on the bearings of the motor / gear unit on the chassis, or by detecting the relative movements of the wheels to the body, by evaluating irregularities in the wheel speed signals, etc.
  • a strategy shown in FIG. 4 has proven itself in practice as a criterion for the detection of the switching intent.
  • the switching lifting speed SG can be obtained, for example, by differentiating the signals from displacement sensors.
  • a longer switching path is required at low switching speeds in order to detect an intention to switch.
  • the shift lever travel SW approaches asymptotically a straight line O drawn in dashed lines, which indicates an offset value for the shift lever travel which must be exceeded in any case so that an intention to shift is detected or is assessed as being present.
  • the offset value O In order to rule out incorrect identification of a shift request, the offset value O must in any case be greater than the play that the shift lever has with respect to the shift forks 56 (FIG. 2), for example on poor roads or as a result of the motor / transmission unit moving suddenly when strong Torques or fluctuations in the torque can move this distance, without this being accompanied by an intention to shift initiated by the driver.
  • the neutral positions can be sensed using the sensor 62 (FIG. 2) and their maximum and minimum values can be detected.
  • the difference between the two sizes is a measure of the play of the external circuit, ie in the transmission path between the shift lever 7 and the shift forks 56 It goes without saying that the neutral position is sensed, for example by means of the sensor 62, only when the switching state N for a predeterminable period of time
  • the disengagement thresholds of the intention to shift are detected by a differential path method, as the differential path between the sensors 104 and 120 of FIG. 5, during operation of the device according to the invention.
  • Decoupling thresholds are considered to be variables that occur during a shift process from the maximum expansion or difference between the sensor data of sensors 104 and 120, that is to say on the transmission and on the shift lever. This determined the maximum difference path during of a switching process can then be converted into a disengagement threshold or processed.
  • These disengagement thresholds can be the same for gear groups such as 1, 3, 5 gear and 2, 4 and R gear or they can be different for all gears.
