Abstract: A vehicle includes an internal combustion engine, brake actuators configured to slow the vehicle in response to braking commands, and a transmission. The transmission includes a plurality of gear sets each having a plurality of nodes, an input member that is continuously connected to the engine and to a node of one of the gear sets, a reverse clutch, a binary clutch assembly, and a controller. The binary clutch assembly is connected at least to the same gear set as the input member, and is applied with the reverse clutch when entering a reverse gear state. The controller executes a method to transmit the braking commands to the brake actuators in response to a requested garage shift into a reverse gear state when the vehicle is rolling above a calibrated speed threshold, and thereby slows the vehicle until a calibrated target slip is achieved across the binary clutch assembly.

Abstract: A system for controlling a hybrid powertrain having an electric motor, an engine and a transmission includes an engine control module that receives a torque request, and when the hybrid powertrain is being powered by the electric motor, determines whether to switch from the electric motor to the engine based on the torque request. A transmission control module, in response to a determination to switch from the electric motor to the engine, determines a target engine speed based on the torque request, and switches the hybrid powertrain from the electric motor to the engine based on a comparison between a current engine speed and the target engine speed.

Abstract: A vehicle includes an engine and transmission assembly, the latter having a stationary member, a plurality of gear sets, an input member, a friction clutch, a binary clutch assembly, and a transmission control module (TCM). The binary clutch assembly includes a freewheeling element and a binary device such as a selectable one way clutch or dog clutch. The TCM selectively delays a release of the binary clutch assembly via a binary clutch indicator method by detecting a requested shift of the transmission requiring an engagement of the friction clutch, and commanding the release of the binary clutch assembly. The TCM determines an amount of slip across the binary clutch assembly and executes the requested shift of the transmission only when the determined amount of slip exceeds a calibrated slip threshold. Slip may be measured or calculated.

Abstract: A vehicle includes an engine and a transmission assembly having a stationary member, gear sets, an input member connected to one of the plurality of gear sets, a binary clutch assembly, and a transmission control module (TCM). The binary clutch assembly includes a freewheeling element which holds torque only in a first rotational direction and a binary device that, when engaged, prevents rotation of the binary clutch assembly in a second rotational direction, and that allows the binary clutch assembly to freewheel in the second rotational direction when released. The TCM executes a method via instructions to determine a total amount of clutch energy of the binary clutch assembly, compare the determined total amount of clutch energy to a calibrated clutch energy threshold, and delay an execution of the requested shift when the determined total amount of clutch energy exceeds the calibrated clutch energy threshold.

Abstract: 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.

Abstract: A vehicle includes an engine and a transmission, the latter of which includes a controller which executes an adaptive speed-based control method. The transmission includes gear sets each having multiple nodes, an input member continuously connected to the engine and to one of the gear sets, and a binary clutch assembly connected to the same gear set as the input member. The controller is programmed to detect a requested transmission shift into an engine braking state while the vehicle is coasting. The controller also commands an increase in engine speed to a target engine speed in response to the requested shift, and applied the binary clutch assembly when the engine output speed reaches the target engine speed. The controller calculates slip across the binary clutch assembly and adjusts the target engine speed as needed over time until the target slip is achieved at the target engine speed.
