摘要： A control system for a hybrid vehicle that includes an internal combustion engine and an electric motor includes an engine speed control module, an air pressure control module, and an engine torque control module. The engine speed control module increases engine speed during a first calibration period based on a driver torque request and a predetermined torque threshold. The air pressure control module decreases intake manifold pressure (MAP) of the engine during a second calibration period based on the driver torque request and the predetermined torque threshold. The engine torque control module starts the engine during a period after the first and second calibration periods by activating N of M cylinders of the engine, wherein N is based on the driver torque request and the predetermined torque threshold.

摘要： A method of output torque smoothing for a hybrid powertrain having an electric machine and a spark ignition engine with a first cylinder and a second cylinder includes commanding a fuel-cut transition, including consecutively initiating and completing deactivation of the first cylinder and initiating and completing deactivation of the second cylinder. The fuel-cut transition is characterized by an absence of retarding spark to the first cylinder and second cylinder. Fuel is supplied to the first cylinder until the first cylinder completes deactivation and to the second cylinder until the second cylinder completes deactivation. The electric machine captures a first torque from the first cylinder by generating electricity until the first cylinder completes deactivation and captures a second torque from the second cylinder by generating electricity until the second cylinder completes deactivation.

摘要： A method is provided for controlling engine stop position in a vehicle having an engine with auto stop/auto start functionality. The method includes automatically ramping down engine speed upon initiation of an auto stop event, executing closed-loop speed control of the engine when the engine speed begins to ramp down, and for as long as the engine speed remains above a threshold engine speed while ramping down the engine speed; executing closed-loop position control of the engine while ramping down the engine speed once the engine speed is less than the threshold engine speed and greater than zero; and stopping the crankshaft to within a calibrated range of a targeted engine stop position. A controller is also provided that includes a hardware module and an algorithm adapted for executing the foregoing method, and a vehicle is provided having an engine with auto stop/start functionality and the controller noted above.
