摘要： A transmission system associated with a vehicle includes a shaft to rotate about an axis of rotation. The shaft is coupled to a gear set. The transmission system includes a target wheel to be coupled to the gear set and to rotate with the gear set. The target wheel includes at least one void. The transmission system includes a giant magnetoresistance (GMR) sensor spaced apart from the target wheel by a gap. The giant magnetoresistance (GMR) sensor is configured to observe the at least one void of the target wheel to determine a rotation speed of the shaft based on a giant magnetoresistance (GMR) effect. The transmission system further includes a rotating shell located in the gap between the target wheel and the giant magnetoresistance (GMR) sensor.

摘要： A park valve performs a multi-plexing function in which an out-of-park circuit is connected to line pressure when the valve is in an out-of-park position and is vented when the valve is in a park position. When particular clutches are released, the out-of-park circuit biases the park valve toward the out-of-park position. To initiate engagement of park, a controller commands a low line pressure, reducing the forces that bias the park valve toward the out-of-park position. Once the valve reaches an intermediate position in which the line pressure circuit is no longer fluidly connected to the out-of-park circuit, the controller commands an increase in line pressure, increasing the forces that bias the park valve toward the park position.

摘要： During a transmission upshift, a torque capacity of an off-going clutch is maintained at a non-zero state during the transition from the torque phase to the inertia phase and throughout a substantial portion of the inertia phase. This permits the inertia phase to be completed faster without an unacceptable increase in output torque during the torque phase. Monotonically reducing the off-going clutch torque and using feedback from an output torque sensor enable sufficiently precise control of the off-going clutch torque capacity during this interval.

摘要： A planetary gear train of an automatic transmission for a vehicle is disclosed. The planetary gear train may include: an input shaft receiving torque of an engine; an output shaft outputting torque; a first planetary gear set including first, second, and third rotation elements; a second planetary gear set including fourth, fifth, and sixth rotation elements; a third planetary gear set including seventh, eighth, and ninth rotation elements; a fourth planetary gear set including tenth, eleventh, and twelfth rotation elements; and a fifth planetary gear set including thirteenth, fourteenth, and fifteenth rotational elements.
