  • Hybrid vehicle powertrain with improved reverse drive performance
    Patent number: 7694762
    Abstract: A hybrid-electric powertrain for a wheeled vehicle having an internal combustion engine, an electric generator, an electric motor and a battery. Transmission gearing establishes multiple torque flow paths including a forward drive torque flow path and a reverse drive torque flow path, the motor being isolated from forward drive gearing elements as it acts as a sole reverse drive power source.
    Type: Grant
    Filed: September 22, 2003
    Date of Patent: April 13, 2010
    Assignee: Ford Global Technologies, LLC
    Inventors: Joseph G. Supina, Stefan P. Pototschnik
  • Powertrain for a hybrid vehicle with all-wheel drive capability and method for controlling wheel slip
    Patent number: 7632202
    Abstract: A hybrid-electric powertrain and control method for a vehicle having forward traction wheels and rearward traction wheels in an all-wheel drive configuration. An engine and an electric motor deliver power through delivery paths to the traction wheels. The power delivery paths may have multiple ratio gearing so that more power can be delivered mechanically to improve powertrain performance and to allow the electric motor size to be reduced. The powertrain may include a controller for automatically balancing power distribution to the forward and rearward traction wheels to avoid wheel slip.
