When a vehicle driver selects reverse while a vehicle is moving forward, a transmission controller applies friction shift elements within the transmission to create a partial tie-up condition to decelerate the vehicle. Once the vehicle slows below a threshold speed, the controller engages a selectable one way brake and releases some of the friction shift elements to engage a reverse gear ratio.

A bicycle gear changing control apparatus includes a controller that is programmed to control a gear changing state of a bicycle transmission according to an operation of a gear changing operating device upon determining a bicycle traveling speed is greater than a first speed. The controller controls the transmission automatically to be in a first prescribed gear changing state upon determining the bicycle traveling speed becomes less than or equal to the first speed and upon determining a gear ratio of a current gear changing state of the transmission is larger than a preset gear ratio of the first prescribed gear changing state. The controller controls the transmission automatically, after controlling the transmission to be in the first prescribed gear changing state, to a larger gear ratio than the gear ratio of the first prescribed gear changing state, upon determining the bicycle traveling speed becomes greater than a second speed.

A method for operating a vehicle having a dual-clutch transmission (DCT). The DCT includes first and second clutches; a first shaft operatively connected to the first clutch, the first clutch being selectively actuated to couple the first shaft to a clutch input member; a second shaft operatively connected to the second clutch, the second clutch being selectively actuated to couple the second shaft to the clutch input member; first and second driving members mounted to the first and second shafts respectively; and an output shaft operatively connecting the first and second driving members to a ground-engaging member of the vehicle. The method includes determining if the vehicle is substantially stationary; and in response to being substantially stationary, actuating the first and second clutches to cause simultaneous driving engagement of both the first and second shafts with the output shaft to thereby lock the output shaft.
