    摘要： The present invention relates to a vehicle (1) having a torque generating machine (4); and one or more driven wheel (WD). A driveline (6) is provided for transmitting torque from the torque generating machine (4) to said one or more driven wheel. The driveline (6) includes a torque transmitting means (8). A first decoupling mechanism (11) is operable to decouple the torque transmitting means (8) from the torque generating machine (4). The first decoupling mechanism (11) is closed to couple the torque transmitting means (8) to the torque generating machine (4) and is opened to decouple the torque transmitting means (8) from the torque generating machine (4). A second decoupling mechanism (12) is operable to decouple the torque transmitting means (8) from the one or more driven wheel. The second decoupling mechanism (12) is closed to couple the torque transmitting means (8) to the one or more driven wheel and is opened to decouple the torque transmitting means (8) from the one or more driven wheel. A controller (2) is provided having at least one electronic processor for controlling operation of the first and second decoupling mechanisms (11, 12). The at least one electronic processor (P) is configured to close the second decoupling mechanism (12) to couple the torque transmitting means (8) to the one or more driven wheel, determine a target operating speed of the torque generating machine (4), control an operating speed of the torque generating machine (4) in dependence on the determined target operating speed and close the first decoupling mechanism (11) when the operating speed of the torque generating machine (4) at least substantially matches the determined target operating speed. The present invention also relates to a corresponding method of controlling first and second decoupling mechanisms (11, 12) to control the transmittal of torque from a torque generating machine (4) to one or more driven wheel of a vehicle (1).

    摘要： A vehicle includes an engine, transmission, and controller. The transmission has gear sets each having multiple nodes, an input member continuously connected to the engine and one of the gear sets, and a binary clutch assembly. The controller executes a method to detect a requested event of a binary clutch engagement and to command a calibrated energy pulse from the engine to the input member in response to the requested event. The energy pulse reduces slip across the binary clutch assembly. The controller applies the binary clutch assembly within a calibrated window of initiation of the pulse, and may shift the transmission into reverse or drive. A transmission has the controller, at least first, second, and third gear sets, an input member selectively connected to the first gear set and continuously connected to the second gear set, and a binary clutch assembly connected to the first and second gear sets.
