摘要： An improved method and apparatus for detecting end-of-fill at a hydraulic clutch in an automatic transmission with a variable force solenoid are provided. The method includes: initiating clutch fill mode by commanding a high current to the solenoid whereby a high fluid pressure is delivered to the clutch apply volume; monitoring clutch fill time; determining if the fill time is greater than a threshold fill time; monitoring the current (e.g., actual and filtered) being actively drawn by the solenoid during clutch fill mode in response to the fill time being greater than the threshold fill time; detecting if an aberration occurs in the current; and stopping distribution of fluid to the hydraulic clutch in response to the current aberration. Detecting if an aberration occurs preferably includes determining a change in instantaneous armature velocity, and determining if the change in instantaneous velocity is greater than a threshold change in armature velocity.

The summer module determines a sum of a derivative of the difference and a product of the difference and a predetermined gain. The position control module controls the current position of the gear actuator based on the sum. The current position of the gear actuator controls a position of a gear synchronizer that slides along an output shaft of the DCT.

摘要： A multiplexed electromechanical shift mechanism includes a single linear actuator with multiple independently selectable linkages actuating a clutch and multiple gears for use in motor vehicle transmissions such as a dual clutch transmission. The linear actuator may be a ball screw, a planetary roller screw or hydraulic or pneumatic operator capable of controlling bi-directional linear motion of an output member. A plurality of linear clutches selectively couple the output member to one of a plurality of linkages adapted to transfer the bi-directional motion of the output member. One of the linkages is coupled to and engages an input (main) clutch of the transmission and the remaining linkages are coupled to and bi-directionally translate shift forks and synchronizer clutches which achieve gear selection and engagement.

摘要： A method of detecting substantial filling of a hydraulic cylinder of a hydraulically operated clutch of a vehicular transmission is disclosed and claimed. A pressure sensor disposed in a hydraulic line to the clutch cylinder provides a signal that the hydraulic pressure has dropped as the clutch cylinder begins to fill and also that the pressure has returned to a substantially normal level. The pressure sensor may be a continuously variable output such as an analog sensor, pulse width modulation (PWM) sensor, a similar device or, less desirably, a two state sensor. An iterative algorithm utilizes data from the sensor and a timer to determine when clutch fill is substantially complete.

摘要： A system for controlling a transmission of a vehicle includes an engine control module that generates a command, while the vehicle is rolling in either a forward or reverse direction, to change a transmission of the vehicle from a reverse drive gear to a forward drive gear. The transmission includes a first clutch, a second clutch, a third clutch, and a fourth clutch. A transmission control module, in response to the command, maintains a first clutch in an engaged state, releases a second clutch and a fourth clutch, with the first clutch in the engaged state and the second clutch and the fourth clutch released, applies a third clutch with a synchronizer to engage the third clutch, and, after the third clutch is engaged, reapplies the fourth clutch to engage the fourth clutch.
