Researchers develop new cost-cutting controls for hybrid vehicles

For a hybrid electrical bus, Oak Ridge National Laboratory researchers person developed and demonstrated algorithm-based controls that yielded up to 30% vigor savings compared with existing controls.

The Integrated Eco-Drive exertion utilized a operation of powertrain power techniques, precocious instrumentality learning and aggregate sensors to find an optimal driving velocity that conserves the astir energy. The technology, developed successful collaboration with the University of California, Riverside, and US Hybrid Corporation, offers important vigor savings for medium- and heavy-duty vehicles operated connected defined autobus and transportation motortruck routes. The strategy was subsequently licensed by US Hybrid.

"Co-optimizing the combustion motor output, electrical centrifugal output and battery authorities of charge—and taking into relationship the repeated route—helps america guarantee the champion performance," said ORNL's Zhiming Gao.

"We tin use this aforesaid strategy to light-duty cars and trucks, particularly networks of connected vehicles, and recognize important vigor savings," ORNL's Tim LaClair said.
