Fuel economizing cruise control

摘要

A cruise control has a throttle controller for maintaining the speed of a vehicle at a desired speed. The cruise control can operate in a conventional cruise mode and a fuel economy cruise mode. When in the fuel economy cruise mode, the throttle is held at a fixed position as the vehicle travels within a prescribed range of speeds from the desired speed. The throttle remains fixed until an exit condition occurs or acceleration/deceleration input is supplied at which point the cruise control provides throttle adjustment at less than normal rates.
