Abstract

This paper presents a computation method of a speed profile which minimizes energy loss considering an identified energy loss characteristics and slope inclination of the road. At first, the real driving data are observed to measure the energy consumption and the energy loss, and the energy loss model of target vehicle is identified from measured information. Secondly slope of the driving path is also expressed as a function of the location. Then, the optimization problem is formulated as a non-linear programming problem [11] including identified energy loss model and slope function together with a simple vehicle model. Then the speed profiles which minimizes the energy loss is obtained by solving a formulated optimization problem. Finally the energy efficiency of the obtained speed profile is confirmed.
