  • System and method for improving vehicle driveline operation
    Patent number: 10597025
    Abstract: Methods and systems for operating a hybrid driveline that includes an engine and an electric machine are presented. In one non-limiting example, the engine and electric machine are operated according to a solution of a Hamiltonian that includes a first co-state and a second co-state, an engine fuel flow parameter, a rate of change of battery state of charge parameter, and an emissions flow rate parameter.
    Type: Grant
    Filed: August 18, 2016
    Date of Patent: March 24, 2020
    Assignee: Ford Global Technologies, LLC
    Inventors: Kukhyun Ahn, Mohammad Shakiba-herfeh, David Richens Brigham, Alexander T. Zaremba, Mark John Jennings
  • Adapting engine-on time to driver aggressiveness in a hybrid vehicle
    Patent number: 10252712
    Abstract: A vehicle includes an engine and at least one controller. In response to a change in a rate of change of a driver control input to the vehicle, the at least one controller is programmed to alter conditions under which the engine will be started and stopped such that engine-on time increases due to the rate increasing and decreases due to the rate decreasing.

  • Minimizing engine pull-ups and gear shifts in a hybrid vehicle
    Patent number: 10023179
    Abstract: A hybrid vehicle includes powertrain components such as an engine, an automatic transmission, and a traction motor selectively coupled to the engine via a clutch and to the transmission. At least one controller is programmed to control these powertrain components. The vehicle is driven over a drive cycle that includes multiple engine starts and transmission gear shifts. An amount of fuel consumption used during these engine starts and transmissions gear shifts is stored on an on-board storage device. Subsequently, the engine is inhibited from starting and the transmission is inhibited from shifting gears based on the amount of fuel consumption associated with the engine starts and transmission gear shifts performed during the drive cycle as recalled from the storage device.
