POWER DISTRIBUTION METHOD FOR SERIES HYBRID ELECTRIC VEHICLE

摘要

PURPOSE: A power distribution method of a hybrid electric vehicle is provided to be applied to not only specific driving cycle, but all driving cycles by using an optimized technique based on Equivalent Consumption Minimization Strategy(ECMS). CONSTITUTION: A power distribution method of a hybrid electric vehicle comprises: a step of obtaining a real fuel consumption about required power of an engine-generator; a step of obtaining equivalent fuel at charging or discharging a battery about required power of a battery; and a step of obtaining a distribution rate. In the third step, the sum of the real fuel consumption and the equivalent fuel about required power of the battery is minimized. In the second step, the equivalent fuel about required powder of the battery is minimized.
