  • Patent number: 9873422
    Abstract: A vehicle includes a motor positioned between an engine and a driveline connected to a vehicle wheel, and a controller. The controller controls engine torque and maintains motor torque during wheel torque and driveline component torque reversals to limit a vehicle output torque rate of change through a lash region associated with a range of driveline torque ratios. A method of controlling a hybrid vehicle includes controlling engine torque to a specified profile and maintaining motor torque at a generally constant value during at least one of wheel torque and driveline component torque reversals to limit a vehicle output torque rate of change through a lash region associated with a range of driveline torque ratios.

  • Patent number: 9296380
    Abstract: A hybrid vehicle includes an engine and an electric machine selectively coupled to one another via a clutch. In one mode of operation, the vehicle can be propelled by only the electric machine while the engine is off. When additional torque is required from the engine, at least one controller transmits an engine start request. In order to start the engine, the clutch can be prestroked such that it fills with pressure prior to the engine to start the engine. While the vehicle is on, at least one controller is programmed to prestroke the clutch prior to the engine start request based at least upon the electric machine and the engine generating substantially zero torque. This reduces the overall engine start time.

  • Patent number: 8954215
    Abstract: A hybrid electric vehicle has a traction motor, a driveline connected to a vehicle wheel, and a controller. The controller is configured to control motor torque through a region surrounding vehicle wheel torque reversal, control driveline input torque during torque reversal of driveline output torque to limit rate of change of driveline output torque, and control motor torque during a torque reversal of at least one driveline component to limit rate of change of the torque applied to the driveline component. A method for controlling a vehicle having a traction motor includes controlling the traction motor torque through a region surrounding a vehicle wheel torque reversal, controlling driveline input torque during torque reversal of driveline output torque to limit rate of change of output torque, and controlling traction motor torque during a torque reversal of a powertrain component to limit rate of change of the torque applied to the component.

  • Patent number: 8565990
    Abstract: A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine upon an engine start request, thereby eliminating the need to transfer torque from the motor/generator to the engine. This helps to further reduce torque disturbances in the driveline when the engine is started.

  • Patent number: 8285470
    Abstract: A method and system for limiting a fast transient in an engine in a hybrid vehicle is provided. The predicted fuel loss percentage is calculated from an inferred air-fuel ratio (inferred lambda). The rate limit term is calculated from a measured air-fuel ratio (measured lambda) and an engine torque command change rate. The predicted fuel loss percentage and the rate limit term are inputs into a calibration table to determine an engine power rate limit and an engine torque rate limit. An engine torque command is limited using the engine torque rate limit to control a fast engine torque transient for an engine. An engine power command is limited using the engine power rate limit to control the fast engine power transient for the engine.

  • Patent number: 8192324
    Abstract: A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine at the lowest engine speeds when the engine-required torque is the highest. This reduces the amount of torque necessary to be supplied from the motor/generator, and further helps to reduce torque disturbances in the driveline. If the motor/generator is producing torque to propel the vehicle at the time the engine start is requested, a launch clutch or one or more transmission clutches can be controlled to provide slip between the motor/generator and the vehicle drive wheels to further reduce torque disturbances in the driveline.
