Energy Management of HEV in Platoon Operation with Constant Headway Policy

This paper proposes a real-time energy optimization algorithm for hybrid electric vehicles that operates in a platoon using constant headway control strategy. The driving power of a hybrid electric vehicle can be distributed between the electric motor and the combustion engine. The power distribution makes evaluable energy efficient improvement. Combining the control strategy proposed by a classic cooperative adaptive cruise control (CACC) algorithm, an optimal energy management strategy is evaluated for the host vehicle in a platoon. Through the establishment of simulation experiments, the string stability and real-time energy optimization performance of the control system are verified.
