【発明の名称】自動車用無段自動変速機のクラッチの制御及び調整のための方法及び装置
Document Type and Number:
Japanese Patent JP2003514198
Kind Code:
A
Abstract:
A procedure for the control and regulation of a clutch of an automatic stepless transmission for a motor vehicle in which an electronic control device, via a first or second regulation circuit, determines the behavior of the clutch during three driving conditions and wherein a stepless gear ratio change is carried out from a first into a second gear ratio. In accord with the invention, for the control and the regulation of the clutch during the first driving condition, the first regulation circuit is employed, the size of the regulation thereof being equivalent to the actual value of the motor speed of rotation (n_MOT_IST). During the second driving condition, a second regulating circuit is employed, the size of the regulation thereof being equivalent to the actual value of a difference in speeds of rotation (dnK_IST) of the clutch and during the third driving condition, the clutch is subjected to a controlled pressure value dependent upon various value influences.
