The control system includes an electric power module for shifting the gearbox, an electric power clutch assembly for engaging and disengaging the clutch, and a control module arranged to control the gearbox power module, the clutch power module, the clutch power assembly. The control module operates to energize the gearbox power module in a sense to shift the gearbox to the selected position, and thereafter operates to reengage the clutch. The system preferably also initially disables the throttle control restoring it after gearshift. In one form of the power clutch assembly, an electric motor is positioned within the clutch housing in concentric relation to the clutch shaft and includes a screw drive assembly which is operative to move the clutch release bearing linearly to engage and disengage the clutch. In another form of power clutch assembly, an electric motor powers a hydraulic master cylinder and the output of the master cylinder is delivered to a slave cylinder associated with the clutch to engage and disengage the clutch in response to energization of the motor. In another form of power clutch assembly, an electric motor drives a pump which maintains a predetermined level of pressurized fluid in an accumulator and a solenoid valve delivers pressurized fluid from the accumulator to a slave cylinder in response to receipt of a shift command signal so as to disengage the clutch. Also disclosed are gear select lever assemblies designed to provide a two part shift command signal in which the initial signal is utilized to disengage the clutch and disable the throttle control system, and the second signal is utilized to shift the gearbox to the selected position. …<??>The gearshift is preferably carried out by linear and rotary electric motors (112, 114) in response to signals from control module (26). …<IMAGE>… |
