Controlling internal combustion engine performance in a motor vehicle

A system 10 for controlling internal combustion engine performance in accordance with driver behavior includes a vehicle control computer 12 operable to receive a plurality of vehicle operating parameter signals and control engine fueling based thereon. In accordance with an operational status, or an operational state determined over a predefined time interval, of one or more of the vehicle operating parameter signals such as idle time, excess speed or low mpg, rapid acceleration/deceleration, the system is operable to control available engine performance and notify the driver. The control system 10 is thus operable to reward/penalize driver performance by correspondingly adding/subtracting available engine performance in the form of available engine output power and/or available vehicle speed. Subtracting available engine performance occurs automatically, and adding available engine performance may be either done automatically or according to driver demand. The criteria which determine whether the driver should be rewarded/penalized can be reset, possibly via a satellite link.
