CONTROL OF HIGHWAY VEHICLES FOR MINIMUM FUEL CONSUMPTION OVER VARYING TERRAIN
In this paper we develop a feedback algorithm for driving a highway vehicle for minimum fuel consumption. The algorithm allows the driver to choose an arbitrary steady state velocity for a level road, but modifies the speed for optimal fuel consumption on various grades. The algorithm is derived from the Pontryagin maximum principle to provide a mathematically optimal performance subject to the driver's choice of a trip time limit. Computer simulation is used to illustrate the implications of this analysis for gear shifts, braking and throttle settings as the road grade changes. /Author/TRRL/
