Abstract
An efficiency gauge may be used for controlling an automotive vehicle. At least one vehicle parameter is sampled during vehicle operation and at least one measure of driving efficiency is determined from the sampled vehicle parameters. Efficiency measurement may include determining an estimate of kinetic energy lost. One such estimate is the sampled braking velocity cost found based on the difference of the squares of the last two vehicle velocities if the vehicle has decelerated and braking has occurred.
