Abstract : In order to evaluate delivery routes to determine if battery powered vehicles are efficient, it is necessary to predict the power requirements of the vehicle so that a vehicle having sufficient stored power can operate over that route and return to its garage without completely discharging the batteries. In the past, accurate power estimates have not been possible because of relatively inaccurate grade information. A system for recording terrain profile information is disclosed. The system accurately senses incremental distances traveled by a vehicle inclination, recording both with elapsed time. The incremental distances can subsequently be differentiated with respect to time to obtain acceleration. The acceleration can then be used by the comptuer to correct the sensed inclination.
