Claim One:
1. A method for selecting one or more power sources in a hybrid electric vehicle (HEV) at a particular moment in time for a current route to optimize energy consumption for the HEV, wherein the HEV includes one or more electric engines (EC) and one or more internal combustion engines, comprising off-line and on-line steps: determining, in an off-line processor, a regression model that predicts a terminal cost of a state along a route from features associated with the route and the vehicle, using a computed true costs-to-go of multiple states from multitude of real or imaginary routes; performing, in an online processor in the HEV, truncated dynamic programming, using the regression model to estimate a terminal cost at an end of a truncated time horizon for a current route; and selecting one or more of the power sources for the one or more EC and the one or more ICE based on a minimal cost-to-go of a current state.
