  • Patent number: 8196687
    Abstract: An extended-range electric vehicle includes drive wheels, an engine having an output shaft, a planetary gear set having a node driven by the output shaft of the engine when the engine is on, and first and second electric machines. The first electric machine is connected to another node, and operates as a generator when the engine is on. A one-way clutch is connected to the remaining node. The second electric machine is connected to an output side of the one-way clutch, with a shaft connecting the drive wheels to the second electric machine. A controller provides a forward electric-only (EV) mode, a reverse EV mode, power-split mode(s), and series mode(s). The series mode(s) provide a direct mechanical path between the engine and drive wheels, with the one-way clutch overrunning in the forward EV mode. The one-way clutch may be activated passively or by a PRNDL device.

  • Patent number: 8123656
    Abstract: A hybrid transmission is provided with a motor and a torque-transfer device is operable to transfer torque from the motor to a transmission input member upstream in power flow from the transmission gearing arrangement. The torque transfer device may be a fluid coupling, such as a torque converter, including a torque converter lock-up clutch. In other embodiments, the torque transfer device is a launch clutch that may be either a wet clutch engagable via pressurized transmission fluid, or a dry clutch, such as used in a manual transmission. A disconnect clutch is selectively engagable to operatively connect an engine connection member with the motor to permit the motor to start the engine, such as after a stop. Many embodiments of the transmission include a one-way clutch arranged in parallel with the disconnect clutch. A method of starting the engine using such a transmission is also provided.

  • Patent number: 8036785
    Abstract: A method for controlling a powertrain of a hybrid vehicle having an engine, a motor/generator, a battery that is rechargeable using at least one of the engine and the motor/generator, and a powertrain control module (PCM) includes determining a current location of the vehicle as a starting point of a preferred route, recording a user-selected ending point of the preferred route, and processing route information using the PCM to thereby determine an optimally fuel efficient route for reaching the ending point. The method includes automatically executing the powertrain control strategy over the optimally fuel efficient route by substantially depleting a charge level of the battery as the vehicle travels over the optimally fuel efficient route such that the charge level of the battery is depleted when the vehicle reaches the ending point. When the ending point is not recorded, the PCM can default to a charge-sustaining mode.

  • Patent number: 8011464
    Abstract: A vehicle has a motor and axles which are selectively rotatable by the motor, a reduction gear set, a differential transferring torque from the motor to the axles, and selectable one-way clutch (SOWC) assemblies. The SOWC assemblies are connected to a different one of the axles, and are engaged to transfer torque to the drive axles whenever the motor is energized. The SOWC assemblies are disengaged when the motor is de-energized to prevent rotation of the rotor and various elements of the reduction gear set and differential. A method minimizes parasitic spin losses in an electric rear drive motor (eRDM) system. The method includes engaging a pair of SOWC assemblies when the motor is on to transfer torque from the motor to the axles, and disengaging the SOWC assemblies when the motor is off to prevent rotation of a rotor and of elements of the reduction gear set and differential.

  • Patent number: 7914416
    Abstract: A hybrid transmission is provided that is operatively connectable to an engine. The transmission has an electric motor and a clutch, which may be a brake-type clutch or a rotating-type clutch, depending on the embodiment, integrated within the transmission. Absent the electric motor and the clutch, and with the addition of a torque converter and torque converter lock-up clutch, the transmission would be a non-hybrid, operable automatic transmission. The transmission is operable to provide an electric-only operating ode, an engine-only operating mode, an electrically-variable operating mode and a parallel hybrid operating mode.

  • Publication number: 20110070985
    Abstract: A drive belt tensioner assembly for a motor-generator unit is comprises a motor-generator unit having a rotatable drive pulley, configured to engage a drive belt, extending therefrom. A drive belt assembly housing is fixed to the motor-generator unit and has an inner surface defining an opening through which the rotatable drive pulley of the motor-generator unit extends. A tensioner mounting ring is mounted to, and rotatable with respect to, the drive belt assembly housing. A tensioner pulley is mounted for rotation on the tensioner mounting ring and is configured to engage the drive belt on a side of the motor-generator unit drive pulley. A biasing assembly having a first end mounted to the tensioner mounting ring and a second end mounted in a fixed relationship to the motor-generator unit exerts a biasing force on the tensioner mounting ring to rotate the ring and the tensioner pulley against the drive belt.

  • Publication number: 20110066308
    Abstract: A method for controlling a vehicle having a hybrid powertrain includes monitoring vehicle navigation and traffic patterns associated with a predicted travel path. It extends the powertrain instantaneous controller into a predictive control framework, and utilizes previewed traffic and geographic information based on on-board sensing and navigation information. An impending road load is predicted from which a fuel cost factor is optimized under a model predictive control framework. A state-of-charge trajectory is predicted from the impending road load and operation of the hybrid powertrain system is controlled in response thereto.
