Abstract: Systems and methods for controlling transmissions having CVTs are disclosed with multiple modes and gearing arrangements for range enhancements, where embodiments include synchronous shifting to allow the transmission to achieve a continuous range of transmission ratios, while minimizing “empty” cycling of the CVT during mode shifts. Embodiments provide for wide ratio range and performance and efficiency flexibility, while maximizing CVT usage through synchronous shifting.

Abstract: A bicycle gear hub includes an axle, planetary gear modules, one-way clutches and a shift mechanism. The planetary gear modules are connected in series at the axle. The shift mechanism includes a shift actuator and control pawls movably disposed at different positions of the axle. The shift actuator includes recess portions to control opening and closing of a control protrusion of one control pawl, and further to control a sun gear of the corresponding planetary gear module to the axle. When a high gear is shifted to a low gear, a rotational direction of the shift actuator is identical to a rotational direction for closing the control pawl.

Abstract: A method for operating a drivetrain of a motor vehicle includes elevating a system pressure acting on a plurality of shift elements (A, B, C, D, E, F) when one of at least one positively locking shift element (A, F) is closed in a force-locking-free state, increasing a torque output by a drive assembly (15) and then subsequently reducing the torque output by the drive assembly (15) while the system pressure is elevated by an intervention with the drive assembly (15), and reducing the system pressure after reducing the torque output by the drive assembly (15). The one of the at least one positively locking shift element (A, F) closed in the force-locking-free state or another one of the at least one positively locking shift element (A, F) is opened while the system pressure is elevated and the torque output by the drive assembly (15) changes.

Abstract: A transmission for a motor vehicle includes a first planetary gear set with at least three central gears which are formed by a ring gear and two sun gears or by two ring gears and one sun gear. A second planetary gear set includes two central gears which are formed by one ring gear and one sun gear. One of the central gears of the second planetary gear set is constantly connected in a torque-proof manner to one of the central gears of the first planetary gear set. The one of the central gears of the first planetary gear set differs from and is arranged in a common gear set plane with the one of the central gears of the second planetary gear set. A carrier of the first planetary gear set is constantly connected in a torque-proof manner to a carrier of the second planetary gear set.

Abstract: Provided is an automatic transmission with which a switching mechanism thereof is hardly damaged even if the hydraulic pressure supplied to a hydraulic pressure control circuit temporarily changes. A control part ECU of the automatic transmission TM switches the first brake B1 to the reverse rotation preventing state when a signal indicating that the slider is at a position corresponding to the reverse rotation preventing state is received while the control unit ECU recognized that it has switched the first brake B1 to the fixed state.
