摘要： An electronically controlled shift system is provided for a synchronized manual transmission of a motor vehicle. The shift system provides greater control of gear engagement by determining an optimum shift force at shift time, by adjusting this shift force based upon engine temperature, and by applying variable shift forces to complete a gear shift. In particular, the electronically controlled shift system comprises a manually operated shift lever for selecting a gear, a transmission control module connected to the shift lever for receiving an electrical input signal indicative of a selected gear and a dual motion actuator receiving actuation signals from the transmission control module for actuating a shift rail of the transmission to engage the selected gear. The transmission control module includes a shift-out routine for axially translating the shift rail from a current in-gear position into a neutral position, a shift-across routine for rotating the shift rail (if necessary) from a first neutral position to a second neutral position that aligns with the in-gear position for the selected gear, and a shift-in routine for actuating the shift rail into selected in-gear position. In addition, shift-in routine applies an entry force for taking up synchronizer clearance, determines and applies a synchronization force and applies a lesser end force for easing the shift rail into the in-gear position.
