Case 15450/15451

Optimizing fuel efficiency for HEV by path forecast and RHC algorithm

Keywords:

Hybrid electric vehicles (HEV), dynamic programming, path forecasting, fuel efficiency, state of charge

Applications:

Improving Hybrid Electric Vehicle fuel efficiency by path forecasting

Problem:

Fuel consumption of hybrid electric vehicles and high computation requirements of Dynamic Programming

Technology:

The invention includes a receding horizon control (RHC) algorithm in combination with a novel approach of route decomposition and control of battery charging and discharging when vehicle decelerates/accelerates, to minimize fuel consumption over a pre-planned or predicted route. In addition, the RHC strategy creates a virtual terminal road segment to optimize the Dynamic Programming (DP) procedures, in order to save computing time and efforts.

Advantages:
  • Improve HEV fuel economy
  • Reduce computation requirements
  • Incorporates changes in route information during the trip
