Abstract
A constant horsepower throttle progression control system and method. In order to improve driveability of a vehicle compared to prior art engine controllers, the present invention operates an engine so as to either produce a constant (or nearly constant) output horsepower at all engine speeds for any throttle position, or so as to produce an output horsepower equal to a predetermined percentage of the range between full rated power and motoring horsepower at all engine speeds for any throttle position. The predetermined percentage may or may not be equal to the percentage of full throttle represented by the throttle position, and may or may not be linearly related thereto.
