Abstract
An electro-mechanical clutch actuator system is provided for a transmission having dual input shafts with respective clutches and with a plurality of drive gears rotatably mounted to each input shaft and having synchronizer mechanisms for engaging each drive gear to one of the input shafts. The clutch actuators include an electric motor and a reduction gear assembly for moving a pawl tweeter arm and is assisted by an assist spring. The movement of the pawl tweeter arm transmits torque through a pivot arm which in turn, act to engage or disengage its corresponding clutch. An upshift clutch control algorithm is provided to facilitate shifting to a higher gear, which monitors and regulates movement of the clutch actuator motors.
