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.

摘要： A low noise, high efficiency solenoid pump includes a housing containing a hollow electromagnetic coil. Within the coil resides a pump assembly defining a tubular body having a pair of opposed ends which respectively include an inlet or suction port and an outlet or pressure port and within which a plunger or piston resides. The piston is biased in opposite directions by a pair of opposed compression springs. A first compression spring limits and arrests travel of the piston during the suction or return stroke and a second compression spring limits travel of the piston during the pumping stroke and returns the piston after the pumping stroke. The piston includes a first check valve that opens to allow hydraulic fluid into a pumping chamber during the suction stroke and closes during the pumping stroke to cause fluid to be pumped out of the pumping chamber. A second check valve opens to allow pumped fluid to exit the pumping chamber and the pump body through the outlet or pressure port and closes to inhibit reverse flow.

摘要： A centrifugal pendulum vibration absorber (CPVA) for absorbing torsional vibration created by operation of an engine includes a plurality of pendulums moveable with respect to a rotatable shaft. The pendulums are connected to the rotatable shaft by a plurality of pins that extend through apertures in the pendulum.

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.
