Abstract: A device for power transmission within a hybrid motor vehicle and a method of operating the device. The device is a P2 module and includes a torque converter, an electric motor, a connect/disconnect clutch and a one-way clutch. The torque converter is configured to be coupled to an input member of the transmission. The electric motor includes a rotor that is fixedly connected to the input of the torque converter. The connect/disconnect clutch has an input member configured to be coupled to the output of the engine and has first and second clutch members moveable between a disengaged and engaged positons. The second clutch member is also fixedly connected to the torque converter. The one-way clutch is coupled between the connect/disconnect clutch and the torque converter and has a locked up configuration and an overrunning configuration.

Abstract: A clutch assembly includes a first clutch having a first translator and a friction pack and a second clutch having first and second coupling members, a locking element, and a second translator. The friction pack includes a first plate fixed to the first coupling member and a second plate fixed to the second coupling member. The first translator of the first clutch is movable to an actuated position in which the plates of the friction pack are engaged with one another thereby causing angular velocities of the first and second coupling members to be synchronized. The second translator of the second clutch is movable to an extended position in which the locking element engages the first and second coupling members with one another thereby causing a power flow path through the first and second coupling members.

Abstract: A device for power transmission within a hybrid motor vehicle and a method of operating the device. The device is a P2 module and includes a torque converter, an electric motor, a connect/disconnect clutch and an electro-magnetic controllable clutch. The torque converter is configured to be coupled to an input member of the transmission. The electric motor includes a rotor that is fixedly connected to the input of the torque converter. The connect/disconnect clutch has an input member configured to be coupled to the output of the engine and has first and second clutch members moveable between a disengaged and engaged positons. The second clutch member is also fixedly connected to the torque converter. The electro-magnetic controllable clutch is coupled between the connect/disconnect clutch and the torque converter and has a locked up configuration and a freewheeling configuration.

Abstract: A device for power transmission between an output of a drive engine and an input of a transmission. The device includes a torque converter, an electric motor at least partially axially overlapping the torque converter, a damper system having an input adapted to be driven by the output of the drive engine, and a clutch coupled between the damper system and the torque converter and configured to connect and disconnect the damper with the torque converter.

Abstract: A vehicle includes a transmission mechanical park system, an electronic park brake, and at least one controller. The at least one controller is programmed to in response to (i) a speed difference of a measured speed and an expected speed of a downstream component of the vehicle that transmits torque downstream of the transmission mechanical park system exceeding a calibratable threshold and (ii) an ignition state of OFF, apply the electronic park brake to restrain movement of the vehicle.

Abstract: A rotary switch, used to select the operating range of an automatic transmission, controls solenoid-operated valves corresponding to the selected range to open and close a connection between a range valve assembly and a control pressure source. A forward range selection electric circuit includes a forward range high side driver, a solenoid-operated control valve, the rotary switch, a power source, and a current monitor. There is a similar circuit for the reverse range. A forward range valve and reverse range valve respond to control pressure produced by the circuit to open a fluid pressure source to a line that is pressurized to produce forward drive, a second position opens a connection between the fluid pressure source and a line that is pressurized to produce reverse drive and vents those lines to sump.
