摘要： The present invention provides a control system for a dual clutch automatic transmission having a torque converter. The transmission provides seven forward speeds or gear ratios and reverse. The control system includes a hydraulic pump, a pressure regulator assembly and control valves that provide and release pressurized hydraulic fluid to the torque converter, a pair of input clutches and eight synchronizer clutches. A first pair of control valves are high flow rate valves which are capable of rapidly engaging and disengaging the input clutches. A second pair of high flow rate valves, control valves and spool valves provide a branching control circuit which controls engagement and disengagement of the synchronizer clutches. A control valve linked to the shift lever blocks hydraulic fluid flow to the first pair of high flow rate valves to inhibit input clutch activation when the shift lever is in Park or Neutral.

摘要： A method of controlling the engagement force of the synchronizers of a dual clutch transmission having a plurality of synchronizers to selectively engage and disengage various gear sets, and a plurality of shift actuators adapted to move the synchronizers. The method includes the steps of initiating a control routine to pressurize a shift actuator to move a synchronizer to a predetermined engagement position and determining the necessary level of force required to move the desired shift actuator to the predetermined engagement position such that the engagement movement is effected without excessive force. The method also includes the steps of determining the hydraulic pressure that corresponds to the determined level of force and varying the amount of available hydraulic line pressure delivered to the shift actuator such that the delivered pressure is the amount that corresponds to the determined level of force.

摘要： A method of controlling the positioning of the synchronizers of a dual clutch transmission having a plurality of synchronizers to selectively engage and disengage various gears sets, and a plurality of shift actuators adapted to move the synchronizers. The method includes the steps of initiating a control routine to move a synchronizer to a full engagement position with a gear set and monitoring the positions of all engaged synchronizers. The method also includes reinitiating the control routine to move a synchronizer back into the full engagement position when any engaged synchronizer slips out to a minimum engagement position. Further, the method includes initiating a control routine to move a synchronizer to a neutral position and monitoring the position of all disengaged synchronizers. Also, reinitiating the control routine to move a synchronizer back to the neutral position when any disengaged synchronizer drifts beyond a pre-determined neutral hysteresis position.
