  • System and method for restarting an engine
    Patent number: 12084043
    Abstract: Systems and methods for operating a hybrid vehicle are presented. In one example, an integrated starter/generator (ISG) provides torque to restart an engine after the engine has been shut down and before engine speed is zero. An opening of a throttle is delayed to reduce driveline torque disturbances during engine restarting.

  • Systems and methods for operating a hybrid vehicle with a manual shift transmission
    Patent number: 11066064
    Abstract: Systems and methods for operating a vehicle that includes a manual transmission are presented. In one example, a speed rate of change of a driveline torque source is adjusted during a shifting of gears of the manual transmission responsive to a gear that is being disengaged and a gear that is being engaged during the shifting of gears. The torque source may be an electric machine and/or an internal combustion engine.

  • Methods and systems for hybrid driveline control
    Patent number: 9937913
    Abstract: Systems and methods for operating and hybrid driveline are presented. In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity.

  • Methods and system for operating a vehicle transmission
    Patent number: 9791040
    Abstract: Systems and methods for operating a transmission of a hybrid vehicle's driveline are presented. In one example, the systems and methods adjust operation of an electrically driven transmission pump that supplies transmission fluid to one or more transmission components in response to a rotational stopping position of a mechanically drive transmission pump.

  • Methods and systems for improving hybrid vehicle gear shifting
    Patent number: 9707953
    Abstract: Systems and methods for improving transmission shifting of a hybrid vehicle are presented. In one example, output torque of an electric machine is adjusted in response to a downshift of a fixed step ratio transmission during regenerative braking. The output torque of the electric machine may be adjusted in response to a phase of the transmission shift.

  • Vehicle system and method for providing anticipatory line pressure for transmission engagements
    Patent number: 9477236
    Abstract: A method according to an exemplary aspect of the present discourse includes, among other things, controlling a vehicle by pressurizing a transmission pump in response to an anticipated shift change trigger. The anticipated shift change trigger may include touching a shift device of the vehicle, or detecting that a vehicle occupant is in proximity to the shift device of the vehicle.
