Real time control of hybrid electric vehicle on a prescribed road

摘要

Hybrid vehicles use two energy sources for their propelling. In order to investigate an optimal splitting of the power flows between the engine and the electric machine, an optimal control algorithm is recalled. A new formulation using maps allows a very fast solving this problem which then may be used in real time control. In the particular case of a hybrid vehicle on a prescribed route, a new control strategy is proposed. It consists in computing an optimal control on the prescribed route and then updating the computed values in order to cope with the difference between the actual and prescribed vehicle route.
