Abstract
Official abstract text for this publication.
A hydraulic control system for a dual clutch transmission includes a plurality of solenoids and valves in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators. The clutch actuators are operable to actuate a plurality of torque transmitting devices and the synchronizer actuators are operable to actuate a plurality of synchronizer assemblies. Selective activation of combinations of the solenoids allows for a pressurized fluid to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of controlling a dual clutch and a plurality of synchronizers in a transmission, the method comprising: selecting an actuator from a plurality of actuators that actuates a synchronizer of one of the plurality of synchronizers or engages a clutch from one of a first and a second clutch of the dual clutch in order to achieve a desired speed ratio in the transmission; actuating the selected clutch of the dual clutch with a pressurized hydraulic…
