ABSTRACT:
A control system (104) for controlling execution of 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) indicative of manual selection of upshifts or downshifts from a currently engaged gear ratio and processing the same in accordance with predetermined logic rules to issue command output signals to a transmission actuator (112, 70, 96) to implement the selected shifts upon a manual caused torque break of the transmission and manual substantial synchronization of the transmission thereafter. The predetermined logic rules include an algorithm providing enhanced recovery from a missed shift condition.
