Abstract
An operator input control system for a system to assist shifting in a multi-speed transmission includes a switch that allows an operator to provide an indication of the direction of the next shift. The operator is also provided with a switch that allows a request for torque elimination to move the transmission to neutral without clutching. In one embodiment, the operator is able to provide the shift indication separately from requesting torque elimination. In a second embodiment, a single three position switch is utilized to provide both the request for torque elimination and the shift indication. The system is operable to initially eliminate or reduce the torque load between the engine and the transmission such that the operator is able to move the transmission to neutral without clutching. The system then begins to move the engine output speed to a speed that is synchronized with the value necessary at the next gear to achieve a relatively smooth speed shift.
