Power management strategies for a series hydraulic hybrid drivetrain

International Journal of Powertrains (IJPT), Vol. 1, No. 1, 2011

Abstract: This paper presents implementation details for two optimisation-based energy management strategies for a series hydraulic hybrid drivetrain. The first strategy is a causal, real-time implementable instantaneous consumption minimisation strategy that requires minimal information about future loads on the system. The second strategy is a non-causal but formally trip-optimal power allocation scheme involving Dynamic Programming (DP). Both strategies are applied to a medium duty urban truck featuring independent hydrostatic wheel drives and fuel economy results are compared to those obtained with a commonly cited real-time implementable, rule-based power management strategy.
