  • System and method for adjusting engine speed and/or engine load to improve fuel economy without causing vehicle vibration that is perceivable by a vehicle occupant
    Patent number: 9284903
    Abstract: A system according to the principles of the present disclosure includes a vibration level module and an engine operation control module. The vibration level module estimates a first level of vibration in a vehicle due to contact between tires of the vehicle and a road surface as the vehicle travels over the road surface. The vibration level module estimates a second level of vibration in the vehicle due to an engine in the vehicle. The engine operation control module selectively adjusts at least one of a speed of the engine and a load on the engine when the second vibration level is less than the first vibration level.
