    • A powertrain in a vehicle includes an electro-mechanical transmission having a selectable one-way clutch mechanically-operatively coupled to an internal combustion engine and configured to selectively transmit mechanical power to an output member. A control method includes monitoring a vehicle speed, monitoring a transmission gear state, comparing the vehicle speed to a threshold low speed range, transitioning a selectable one-way clutch into an engaged mode when said vehicle speed is not in a forward direction in excess of the threshold low speed range, and maintaining the selectable one-way clutch in the engaged mode based upon the transmission gear state remaining in a first gear state and the vehicle speed remaining within said threshold low speed range, a neutral state, or a reverse state.

    • A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has an input member connected for common rotation with one of the members of four planetary gear sets and an output member connected for common rotation with another of the members of the planetary gear sets. Four interconnecting members connect different members of the planetary gear sets for common rotation. A first brake is selectively engagable to ground the first member of the first planetary gear set to the stationary member. A first, a second, and a third rotating clutch are each selectively engagable to connect a different respective pair of the members of the planetary gear sets for common rotation. A selectable one-way braking clutch is configured to brake in one rotational direction and is selectively reversible to brake in an opposite rotational direction, and freewheels in some speed ratios.
    • 用于车辆的多速变速器设置有可选择的单向制动离合器(SOWBC)。 变速器具有与四个行星齿轮组的构件中的一个共同旋转的输入构件和与行星齿轮组的另一个构件共同旋转连接的输出构件。 四个互连构件连接行星齿轮组的不同构件以进行共同旋转。 第一制动器选择性地可接合以将第一行星齿轮组的第一构件接地到固定构件。 第一,第二和第三旋转离合器各自选择性地可接合以连接用于共同旋转的行星齿轮组的不同相应的一对构件。 可选择单向制动离合器构造成在一个旋转方向上制动并且选择性地可逆地在相反的旋转方向上制动,并且以一定的速度比自由轮。
