POWER CONTROL METHOD AND SYSTEM OF HYBRID VEHICLE USING DRIVING INFORMATION

摘要

The present invention relates to a dynamic power control method and a dynamic power control system of a hybrid vehicle using driving information. More particularly, the dynamic power control method of the present invention includes the steps of: acquiring driving information including at least one of altitude information about speed profile or driving information about a section for a vehicle to travel; calculating a dynamic power value required during driving of the vehicle on the basis of the acquired speed profile; calculating a parameter to perform power distribution of an engine or a motor of the vehicle according to the dynamic power value; and distributing the dynamic power of the vehicle by applying the parameter to Pontryagin's minimum principle (PMP) theory. By the above configuration, the dynamic power control method and the dynamic power control system using driving information of the present invention can control the dynamic power of the hybrid vehicle having an engine and a motor as a dynamic power source easily, by predicting the driving speed of the vehicle in advance.
