  • Patent number: 10371018
    Abstract: A method, control system, and variable valve timing system are provided for controlling an actuator that can be switched into an on state and an off state with pulse width modulation. The systems and method include controls configured to determine an actual system parameter on a first time schedule and a desired system parameter on a second time schedule. On a third time schedule, a position error difference between the actual system parameter and the desired system parameter is determined. The third time schedule is configured to begin and to determine the position error difference each time that the actual system parameter is determined and each time that the desired system parameter is determined. A desired duty cycle is determined, and a duty cycle command is sent to a pulse width modulation output unit.

    Abstract: A prediction module, based on a set of possible target values for M future times and a model of an engine, determines predicted torques of the engine for the M future times, respectively. M is an integer greater than one. A cost module determines a cost for the set of possible target values based on comparisons of the predicted torques for the M future times with engine torque requests for the M future times, respectively.

  • Patent number: 8825319
    Abstract: A method of controlling the performance of a vehicle from a stationary condition includes operating a vehicle powertrain in a creep mode following the disengagement of a driver-operated braking device; and operating the vehicle powertrain in a launch mode following an engagement of a driver-operated acceleration device subsequent to the disengagement of the driver-operated braking device. Operating a vehicle powertrain in a creep mode includes: applying a friction clutch to couple an engine crankshaft of the vehicle powertrain with an input shaft of the transmission; determining a torque command to accelerate the vehicle powertrain at a predetermined rate; providing the torque command to an engine controller to controllably increase the input torque to the transmission; and operating a closed loop engine speed control module to prevent the crankshaft speed from slowing below a predetermined engine idle speed.

    Abstract: An engine control system includes a spark bound module that determines a bounded spark value based on a desired spark value, a torque bound module that determines a bounded torque value based on the bounded spark value and a desired torque value, and an inverse torque calculation module that determines a desired engine air value based on the bounded torque value and the square of the bounded spark value. The engine air value may be one of a desired air-per-cylinder value and a desired manifold air pressure value. The bounded spark value and the bounded torque value are determined based on one or more of a plurality of engine actuator positions. Related methods for determining the bounded spark value, the bounded torque value, and the engine air value are also provided.
