    Abstract: A continuously variable transmission control system includes a continuously variable transmission (CVT) including a primary variator pulley and a secondary variator pulley each including a set of pulley members defining a variable-width gap, and a flexible member positioned within the variable-width gap and movable to define a CVT ratio. The transmission control system also includes a primary pulley valve controlling a primary pulley pressure of a fluid to the primary variator pulley, a secondary pulley valve controlling a secondary pulley pressure of the fluid to the secondary variator pulley; and a pulley pressure control system configured to recognize and mitigate pressure oscillations occurring in the primary pulley pressure or in the secondary pulley pressure.

    Abstract: A centrifugal pendulum vibration absorber (CPVA) absorbs vibration and transmits a torque between an output of an engine and an input of a transmission of a vehicle. The CPVA includes a plate with at least one retaining member and a first set of vibration absorbers with at least one mass supported by the at least one retaining member. The at least one mass has a predefined movement path with respect to the plate. The CPVA further includes a first torsion vibration damper assembly that connects the CPVA to a turbine of a torque converter that is selectively engaged with engine, and a second torsion vibration damper assembly that connects the CPVA to the transmission. The at least one mass absorbs a vibration of a harmonic order generated by the engine.

    Abstract: A continuously variable transmission (CVT) includes input and output members, a primary variator pulley, and a secondary variator pulley. The respective variator pulleys are responsive to primary and secondary pressures. Speed sensors measure a respective rotational speed of each variator pulley. A controller executes a method by receiving the measured rotational speeds, calculating a current speed ratio of the CVT above a threshold CVT speed ratio using the rotational speeds, comparing the calculated current speed ratio to calibrated threshold ratios during a sudden stop event of the vehicle, and selectively executing a CVT control action after the calculated current speed ratio drops below the threshold CVT speed ratio during the sudden stop event. The control action depends on which of the threshold ratios is exceeded by the calculated current speed ratio after the calculated current speed ratio drops below the threshold CVT speed ratio, and on the measured rotational speeds.

    Abstract: A vehicle includes an engine, torque converter, and transmission assembly. The transmission assembly includes gear sets each having a plurality of nodes, an input member, a binary clutch connected to a node of one of the gear sets, friction clutches, and a controller. The controller detects a requested rolling garage shift of the transmission into a forward drive mode above a calibrated threshold absolute speed, and controls an amount of slip across a selected assisting clutch via modulation of pressure commands to the selected assisting clutch once the vehicle has slowed below the first calibrated threshold speed. The controller also stages the binary clutch to a calibrated staging pressure while controlling slip across the selected assisting clutch, and commands an engagement of the binary clutch and a release of the selected assisting clutch when a speed of the binary node reaches zero or a calibrated low non-zero speed.
