Patent ID: 8382639

Claim:
A hydraulic control system for controlling a dual clutch and a plurality of synchronizers in a transmission, the hydraulic control system comprising: a source of pressurized hydraulic fluid; a first pressure control solenoid in downstream fluid communication with the source of pressurized hydraulic fluid; a second pressure control solenoid in downstream fluid communication with the source of pressurized hydraulic fluid; a first clutch actuator subsystem in downstream fluid communication with the first pressure control solenoid for selectively actuating the dual clutch; a second clutch actuator subsystem in downstream fluid communication with the second pressure control solenoid for selectively actuating the dual clutch; a control device in downstream fluid communication with the first pressure control solenoid and the second pressure control solenoid, the control device operable to selectively communicate hydraulic fluid from whichever of the first and second pressure control solenoids provides a hydraulic fluid having a greater pressure; a first synchronizer solenoid in downstream fluid communication with the control device; a second synchronizer solenoid in downstream fluid communication with the control device; a first valve in downstream fluid communication with the first and second synchronizer solenoids; a second valve in downstream fluid communication with the first valve; and a plurality of actuators operable to selectively actuate the plurality of synchronizers, wherein at least a first of the plurality of actuators is in downstream fluid communication with the first valve and at least a second and a third of the plurality of actuators is in downstream fluid communication with the second valve.
