Abstract

A hybrid vehicle includes a drive train, an electrical energy source coupled to the drive train and electrically connected to an electric energy storage device having a state-of-charge, and a non-electrical energy source coupled to the drive-train. A convexification model for the vehicle is used for determining at least one control parameter for operating the vehicle. By applying a convex approach for forming the at least one control parameter it is possible to be sure that the at least one control parameter in fact is a presently optimized parameter. Furthermore, the convex approach minimizes the computational resources necessary for determining the at least one control parameter. The use of a minimal amount of computational resources is specifically desirable in relation to a vehicle on-board solution, typically implementing real-time, continuous, calculations of the at least one control parameter. A corresponding method and computer program product are also provided.
