摘要： A bi-directional overrunning clutch assembly employed in connection with a reduced capacity low friction clutch to provide low and reverse gears in a transmission. The clutch assembly including an inner race, an outer race, and engagement members supported therebetween. The inner race is operatively coupled to the transmission casing and the outer race is operatively coupled to the ring gear of the gear set as well as the inner race of the friction clutch assembly. The clutch assembly further includes at least one actuating cam. The actuating cam operates to actuate the engagement members to provide four separate modes of operation between the inner and outer races of the clutch assembly. More specifically, the cam is operable to (1) disengage the engagement members to provide freewheeling between the inner and outer races in both rotational directions; (2) to actuate engagement members so that torque is translated in one rotational direction but to allow freewheeling in the opposite rotational direction; (3) to actuate the engagement members so that torque is translated in a direction opposite to that in mode (2) above, but allow freewheeling in the rotational direction opposite to that in which torque is translated in this mode; and (4) to actuate the engagement members so that the inner and outer races are locked relative to each other and torque is translated in both rotational directions.

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 hydraulic actuation of the clutches and the synchronizers in a dual clutch transmission in the event of a clutch or synchronizer fault. The method includes the steps of determining which clutch is faulted when a clutch-on fault is detected, then commanding an interruption of engine torque to the faulted clutch and a neutralization of all synchronizers of the same axis shaft as the faulted clutch. The method further senses if a synchronizer actuator-on fault has occurred, then determines which synchronizer is faulted if an actuator-on fault has is detected. The method steps further include preventing the further actuation of the other synchronizers on the same axis shaft as the faulted actuator.

摘要： A method of controlling the torque transferred across the engaged clutch of a vehicle having a dual clutch transmission to provide predetermined engine acceleration for each gear based on the engine throttle position and subsequent changes of clutch speed that are in response to operatively varying the torque transferred across the engaged clutch as the engine accelerates to a predetermine speed based on the throttle position. The method includes the steps of determining the engine throttle position, determining the currently engaged gear of the transmission, and sensing the speed of the driven member of the engaged clutch. Then, a target engine speed is determined based on the engine throttle position, the currently engaged gear, and the clutch speed. The torque transferred across the engaged clutch is then continuously varied to cause the engine to accelerate toward the target engine speed.
