Abstract
The present disclosure describes systems and methods for controlling the speed of a vehicle comprising: during a pulse phase of cruise control, applying engine torque to raise speed, the amount and duration of which being responsive to engine speed; and during a glide phase of cruise control, discontinuing engine combustion. In this way cruise control may maintain a mean speed equivalent to a desired, threshold speed while reducing fuel consumption, and NVH effects felt by the end user compared to traditional cruise control methods.
