Abstract
A method is provided for controlling a hybrid electric vehicle that includes an internal combustion engine having a cylinder provided with an intake valve, an exhaust valve, and a piston configured to rotate the engine's crankshaft. The method includes determining whether deceleration of the vehicle is desired and also includes ceasing supply of fuel to the cylinder when such condition is satisfied. The method additionally includes selecting a fuel-off actuation arrangement for the intake valve via a mechanism configured to provide variable valve timing and lift, such that a magnitude of compression pulses in the cylinder during deceleration is limited. A system for controlling the hybrid vehicle and a vehicle employing such a system are also provided.
