Definitions

  • the invention relates to a method for learning force-free gear positions of a manual transmission of a vehicle, in which a shift intent on a shift lever and the gear positions of the manual transmission is detected by sensors, wherein in a learning routine by means of the shift lever, a respective gear is switched.
  • EKM electronic clutch management
  • the invention has for its object to provide a method in which reli sig can be concluded on a power freedom of the gear positions.
  • the object is achieved by evaluating a plurality of position values delivered by a shift lever sensor and / or gear position sensors, wherein in the case of a match of the position values output repeatedly by one of the sensors, it is concluded that the gear position is free of force.
  • a plurality of position values given by the shift lever sensor or the respective gear position sensor it is possible to reliably detect whether the determined position value is constant and thus actually the power-free state of the gear position is set. If different values occur, the position is interpreted as not free of force.
  • a position value is entered into a control unit during a read-in process, whereby a plurality of read-in processes for inputting one position value are carried out successively by each sensor and the position values output in the successive read-in processes by the respective sensor are checked for conformity.
  • a number of read-in processes to be monitored can be calibrated.
  • the calibration depends on the complexity of the clutch and transmission system.
  • the position values emitted by the respective sensor are stored after the power position of the gear position has been determined. This ensures that no faulty position is stored in the control unit, which could falsify the other switching operations.
  • the gear position when comparing the multiple position values to a force-free, is closed when all position values lie within a tolerance band.
  • the tolerance band the sensor-typical signal behavior of the signals emitted by the sensors is taken into account when comparing the position signals.
  • the tolerance band is calibrated depending on a noise behavior of the signals output by the sensor.
  • position values occurring within the tolerance band can be rated as approximately the same.
  • the tolerance band is calibrated gear specific. This increases the safety in the determination of the position values, since the learning process is geared specifically encountered.
  • the learning process is acknowledged with an error if the freedom of the gear position is not given.
  • This error display aborts the learning process and prevents storage of the detected position values.
  • the learning routine is executed at a first startup or a restart of the manual transmission. This will ensure that the engagement in the transmission, the correct position values of the sensors are used for the detection of egg ner force-freedom of the gear position.
  • EKM electronic clutch management systems
  • clutch by wire systems a learning routine is started during commissioning at the end of the vehicle by the vehicle manufacturer, at which position values of the transmission system are determined for force-free gear positions.
  • Force-free means that the shift lever used to engage a gear is not affected by an external force (for example, a driver's hand).
  • An external tester starts this learning routine, in which a communication with a control unit of the transmission system is established.
  • a shift lever sensor for determining a position of the shift lever and two gear position sensors are connected, which detect the gear position in a selection or switching operation.
  • a learning process is triggered for each engaged gear
  • Each position value detected by a sensor is read into the control unit during an interrupt (read-in process).
  • Several position values of a sensor are read into the control unit in several consecutive interrupts.
  • the control unit compares the multiple position values of each sensor with each other.
  • the number of interrupts can be calibrated and can be between 2 and 100 interrupts.
  • the gear position is assumed to be free of force.
  • the tole ranzband is calibrated gear specific depending on a noise behavior of thetiklese NEN sensor signal. If the position values detected during different interrupts change and these are at least partly outside the tolerance band, the respective position must be evaluated as not free from force.
  • the learning routine must acknowledge the learning process as faulty. This acknowledgment can be made with a specific error message, such as "position not stable".
  • the described learning process is performed separately within the learning routine for each gear and thus reliably determines the force-free gear position for each gear of the transmission.

Abstract

L'invention concerne un procédé pour acquérir des positions de vitesse d'une boîte de vitesses à commande manuelle d'un véhicule n'étant pas soumises à une application de force, procédé consistant à détecter, au moyen de capteurs, une intention de changement de vitesse au niveau d'un levier de changement de vitesse ainsi que les positions de vitesse de ladite boîte de vitesses à commande manuelle, une vitesse respective étant engagée au moyen du levier de changement de vitesse lors d'une routine d'acquisition. L'invention concerne un procédé permettant de déterminer avec fiabilité qu'une position de vitesse n'est pas soumise à une application de force, consistant à évaluer des valeurs de position fournies par un capteur de levier de vitesse et/ou des capteurs de position de vitesse. Il est possible de déterminer que la position de vitesse n'est pas soumise à une application de force lorsque les valeurs de position émises successivement plusieurs fois par un des capteurs sont concordantes.
