Method of smoothing output torque
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.
