Steuereinrichtung und Verfahren zur Einleitung eines Gangwechsels für ein mechanisches Getriebesystem.

摘要

A control system (104) for at least partially automatically executing manually selected upshifts and downshifts of a mechanical transmission system (10) is provided. The control system includes a central processing unit (106) for receiving input signals indicative of transmission input shaft (16) and output shaft (90) speeds and from a driver control console (108) and processing the same in accordance with predetermined logic rule to issue command output signals to a transmission actuator (112, 70, 96) to implement the selected shifts. The processing unit logic rules include rules for sensing conditions indicative of non-torque lock at an engaged jaw clutch and for issuing commands to disengage an engaged jaw clutch only if non-torque lock conditions are sensed.
