摘要： A method of controlling a hydraulic control system for a dual clutch transmission includes controlling a plurality of pressure and flow control devices 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 pressure control solenoids and the flow control 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.

摘要： The present invention provides a method of operating an electro-hydraulic control system for a dual clutch transmission having seven forward speeds or gear ratios and reverse. The control system includes an oil delivery subsystem, a clutch control subsystem and a synchronizer control subsystem. All three subsystems are under the control of a transmission control module. The method of operation includes gathering data from various shaft speed, clutch position and shift actuator position sensors and utilizing pressure control (PCS) and flow control (FCS) solenoid valves and a logic valve to pre-stage and engage (and disengage) hydraulic shift actuators associated with a requested and current gear and to sequentially engage one of a pair of input clutches.

摘要： A clutch control system for a vehicle includes a shift command module and an offgoing clutch control module. The shift command module commands an upshift of a clutch-to-clutch transmission when an engine torque is less than a predetermined negative torque. The offgoing clutch control module increases an offgoing clutch pressure above a predetermined apply pressure in response to the command. An offgoing clutch is fully engaged when the offgoing clutch pressure is greater than the predetermined apply pressure.

摘要： A control system includes a pressure control solenoid and a flow control solenoid having an input in fluid communication with the pressure control solenoid. A piston adjusts a position of a shift fork and includes a first area in fluid communication with the pressure control solenoid and a second area in fluid communication with the flow control solenoid. A fork sensor senses a position of a shift fork. A flow determining module determines a fork velocity for the shift fork, adjusts the fork velocity to generate an adjusted fork velocity based on the position, and generates a flow command for the flow control solenoid based on the adjusted fork velocity. A pressure determining module generates a pressure command for the pressure control solenoid. The shift fork is at least one of moved from a sync position to an engaged position and from an engaged position to a neutral position.
