<p>A control system (104)/method for semi-automatically executing manually or automatically 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, the throttle pedal position (THD) and from a driver control console (108) indicative of selection of upshifts or downshifts from a currently engaged gear ratio and processing the same in accordance with predeterined logic rule to issue command output signals to a transmission actuator (112, 70, 96) and to a fuel controller operator to implement a shift substantial synchronization of the transmission after manual initiation of the shift sequence by a manually caused torque break. <IMAGE></p> |
