Patent ID: 8590684

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 first pressure control solenoid for selectively actuating the dual clutch; a first synchronizer solenoid in downstream fluid communication with the second pressure control solenoid; a second synchronizer solenoid in downstream fluid communication with the second pressure control solenoid; a third synchronizer solenoid in downstream fluid communication with the second pressure control solenoid; a fourth synchronizer solenoid in downstream fluid communication with the second pressure control solenoid; and a plurality of actuators operable to selectively actuate the plurality of synchronizers, wherein the plurality of actuators are each in downstream fluid communication with the second pressure control solenoid and wherein each of the plurality of actuators are in downstream fluid communication with a respective one of the first, second, third, and fourth synchronizer solenoids, and wherein each of the plurality of synchronizers is engaged by selectively controlling the flow of hydraulic fluid from the first, second, third, and fourth synchronizer solenoids to the plurality of actuators.
