Integrated control module for use in a dual clutch transmission having integrated shift actuator position sensors

Abstract

An integrated control module for a dual clutch transmission having an integrated shift actuator position sensor assembly that includes a valve body having a plurality of raised portions juxtaposed to each other with a plurality of shift actuator bores piston bores formed therein. A plurality of shift actuators are adapted to operatively move the synchronizers of said transmission to affect gear changes, and include a plurality of shift actuator pistons slidingly disposed within the shift actuator bores. A hydraulic control assembly is adapted to control the operative hydraulic functions of the transmission. A transmission control assembly in electrical communication with the hydraulic control assembly and with a higher level vehicle control system provides the requisite signals to control the hydraulic control assembly. A sensor assembly is also included that has a plurality of detecting elements fixedly mounted to the raised portions of the valve body and a plurality of reference elements fixedly mounted to each of the plurality of actuator pistons such that the detecting elements can sense the movement of the actuator pistons within the actuator piston bores to determine the positions of the transmission synchronizers.
