Definitions

  • the present invention relates to a method for adapting the clutch characteristics in a double clutch system.
  • the electromechanical clutch actuator can be divided into three components, particularly in automated manual transmissions.
  • the first component relates to the clutch actuator, which comprises a drive unit regulated by the control software, which is, for example, an electric motor and a displacement unit.
  • the second component is a clutch release, which transfers the release force of the drive unit to the plate spring of the clutch.
  • the third component relates to a transmission system for transmitting mechanical forces between the clutch actuator and the clutch release.
  • the transmission system includes a lever mechanism, a mechanical shaft and / or hydraulic lines, etc.
  • the clutch can be actuated by moving to a specific position of the drive unit of the clutch actuator.
  • the clutch release mechanism is actuated by the transmission system and the clutch is either closed or opened or a specific torque is set.
  • the position of the drive unit can preferably be monitored with absolute displacement sensors.
  • the conversion to a transmitted clutch torque is calculated in the control software using the clutch characteristic curve in which the transfer function "torque over the master cylinder travel" is stored.
  • the object of the present invention is to provide a method for adapting the clutch characteristics in parallel shift transmissions, by means of which a correction of the transmission behavior of clutches in double clutch systems or parallel shift transmissions is possible.

Abstract

L'invention concerne un procédé permettant d'ajuster les caractéristiques d'embrayage d'un système de double embrayage (PSG) comprenant dans une première branche un premier embrayage (A) ainsi qu'une première boîte de vitesses partielle (iA) située en aval, et dans une seconde branche un second embrayage (B) ainsi qu'une boîte de vitesses partielle (iB) située en aval. La première branche et la seconde branche peuvent être reliées à un moteur d'entraînement (M) côté entrée et aux roues (F) d'un véhicule côté sortie. Le premier embrayage (A) est actionné par l'intermédiaire d'un premier mécanisme d'actionnement d'embrayage (KA) et le second embrayage (B) par l'intermédiaire d'un second mécanisme d'actionnement d'embrayage (KB). Une remise à zéro de l'odométrie du premier et/ou du second mécanisme d'actionnement d'embrayage (KA ; KB) est effectuée conformément à une stratégie prédéterminée en fonction de critères prédéterminés.
