Patent ID: 7073407

Claim:
An integrated control module for a dual clutch transmission having an integrated shift actuator position sensor assembly, said module comprising: a valve body having an inlet in fluid communication with a source of pressurized hydraulic fluid, a plurality of outlets, and a plurality of internal hydraulic passages disposed therebetween, said valve body further 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 that are adapted to operatively move the synchronizers of said transmission to affect gear changes, said plurality of shift actuators including a plurality of shift actuator pistons slidingly disposed within said shift actuator bores; a hydraulic control assembly mounted to said valve body that is adapted to operatively control the pressurized hydraulic fluid from said inlet through said plurality of internal hydraulic passages to said plurality of outlets to control the operative hydraulic functions of said transmission; a transmission control assembly mounted to said valve body in electrical communication with said hydraulic control assembly and with a higher level vehicle control system, said transmission control assembly adapted to be operatively responsive to said higher level control system to provide the requisite signals to control said hydraulic control assembly; and a sensor assembly having a plurality of detecting elements and a plurality of reference elements, at least one of said plurality of detecting elements fixedly mounted to at least one of said plurality of raised portions of said valve body and at least one of said plurality of reference elements fixedly mounted to each of said plurality of actuator pistons such that said detecting elements can sense the movement of said actuator pistons within said actuator piston bores to determine the positions of the transmission synchronizers.
