摘要： A vehicle includes an engine, torque converter, and transmission assembly. The transmission assembly includes gear sets each having a plurality of nodes, an input member, a binary clutch connected to a node of one of the gear sets, friction clutches, and a controller. The controller detects a requested rolling garage shift of the transmission into a forward drive mode above a calibrated threshold absolute speed, and controls an amount of slip across a selected assisting clutch via modulation of pressure commands to the selected assisting clutch once the vehicle has slowed below the first calibrated threshold speed. The controller also stages the binary clutch to a calibrated staging pressure while controlling slip across the selected assisting clutch, and commands an engagement of the binary clutch and a release of the selected assisting clutch when a speed of the binary node reaches zero or a calibrated low non-zero speed.

摘要： A method of executing a double transition shift in a transmission includes determining via a controller that one of four clutches involved in the shift has a clutch slip direction relative to input member rotation direction in one of the current gear and the commanded gear and an opposite clutch torque direction relative to input member torque direction in the other of the current gear and the commanded gear. The controller then calculates clutch torques for at least some of the offgoing clutches and at least some of the oncoming clutches, and controls torque at the offgoing clutches and the oncoming clutches during the shift according to the calculated clutch torques to ensure that the clutch with the opposite slip and torque directions does not provide reaction torque during the shift unless clutch slip across said one of the four clutches is zero or in the clutch torque direction.

摘要： A vehicle includes an engine, a transmission having a friction clutch and a binary clutch assembly, and a controller. The controller executes a method to detect the requested shift of the transmission to neutral, and when a set of conditions are satisfied during the requested shift, to automatically decrease a pressure command to the friction clutch such that torque capacity of the friction clutch decreases from a full torque capacity and begins to slip. The controller holds the binary clutch assembly at a calibrated pressure while the friction clutch slips, disengages the binary clutch assembly only when the binary clutch assembly is released and not loaded, and increases the pressure command to the friction clutch to restore full torque capacity to the friction clutch and complete the requested shift to neutral.

摘要： A vehicle includes a transmission having a plurality of clutches, including an oncoming binary clutch and an off-going clutch. The oncoming binary clutch is a binary device and the off-going clutch is a non-binary device. An internal combustion engine is operatively connected to the transmission and configured to generate an engine torque based on an input torque request. A controller is operatively connected to the transmission and has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for controlling a power-on downshift with the off-going clutch and the oncoming binary clutch. The controller is configured to generate a first pressure command at below a threshold pressure to at least partially pressurize the oncoming binary clutch and initiate a clutch slip for the off-going clutch. Among other steps, the controller is configured to determine if synchronization is met.
