摘要： A vehicle includes an engine, torque converter, transmission, accumulator, sensor, and controller. The engine is automatically restarted in response to a start signal during an engine auto-start event. The transmission has a calibrated line pressure and a plurality (n) of clutches. The (n) clutches are engaged to execute the engine auto-start event. The accumulator delivers fluid under pressure to the transmission in response to the start signal. The controller controls (n−1) of the plurality (n) of clutches to the calibrated line pressure in response to detecting the start signal. The controller also modifies clutch fill parameters which control a fill sequence of the remaining clutch, i.e., the designated control clutch, as a function of a deviation of the measured turbine speed from a theoretical no-slip turbine speed. A system includes the transmission, sensor, accumulator, and controller. A method for controlling the designated clutch is also disclosed.

摘要： A vehicle includes an engine, a multi-speed transmission with a neutral idle (NI) mode capability, and a controller. The controller allows direct entry into the NI mode during a garage shift (GS) event. One clutch is actuated during the GS event, and a different clutch is actuated to directly enter NI mode after completing the GS event. A method allows for direct entry into a neutral idle (NI) mode during a garage shift (GS) event using a multi-speed transmission. The method includes automatically actuating a first clutch of a plurality of clutches to complete the GS event, and a second clutch of the plurality of clutches to directly enter the NI mode after completing the GS event. The method may include holding the NI clutch at a pre-learned NI pressure during a fill stage of the GS clutch, and varying a turbine pull-down rate to provide different GS shift feels.

摘要： A vehicle includes an engine, a torque converter, a transmission, and a controller. The transmission has an input member connected to a turbine of the torque converter. The transmission includes a neutral idle (NI) state and a designated NI clutch actuated to enter the NI state. The controller calculates a reference slip error as a function of engine speed and turbine speed, detects when the designated NI clutch is exhausting while operating in the NI state as a function of the reference slip error, and executes a control action when the exhausting NI clutch is detected. A method includes measuring engine and turbine speed, calculating the reference slip error value as a function of the engine and turbine speeds, detecting when the designated NI clutch is exhausting while operating in the NI state using the reference slip error, and executing a control action when the exhausting NI clutch is detected.

摘要： A transmission includes a plurality of clutches that are selectively engageable alone or in combination with each other to establish a plurality of forward drive modes, wherein one of the clutches is configured as a neutral idle (NI) clutch that is selectively actuated to shift the transmission into an NI state, and a controller. The controller is adapted to shift the transmission from a forward drive mode into the NI state during a coast-down maneuver prior to the transmission reaching a zero output speed. A method of shifting the transmission into the NI state includes determining the presence of a predetermined one of the forward drive modes using the controller, and using the controller to actuate a designated one of the clutches as an NI clutch to enter the NI state during the forward drive mode, during a coast-down maneuver, and prior to the transmission reaching a zero output speed.
