Summary: Due to air quality concerns and rising fuel prices, urban bus fleets are increasingly adopting hybrid electric vehicles (HEVs) for their higher efficiency and lower emissions. This paper proposes an algorithm to adapt the energy management strategy (EMS) of HEVs to specific driving conditions on a particular bus route. The algorithm estimates the driving cycle based on a previous trip and applies dynamic programming and one-step look-ahead to optimize energy consumption. Simulation results show that the proposed method can keep the battery charge within the required range and achieve near-optimal performance.
