The computationally demanding Dynamic Programming (DP) algorithm is_x000D_ frequently used in academic research to solve the energy management problem of an_x000D_ Hybrid Electric Vehicle (HEV). This paper is focused exclusively on how the computational_x000D_ demof such a computation can be reduced. The main idea is to use a local_x000D_ approximation of the gridded cost-to-go derive an analytic solution for the optimal torque_x000D_ split decision at each point in the time state grid. Thereby it is not necessary to ..._x000D_
