Whistle down the wire

Collaboration between OEMs and suppliers leads to new advances, and challenges, for electrohydraulic system control.

Off-highway OEMs have found that electrohydraulics are particularly suited to platforms where there is a high degree of coordination required between the propulsion and work functions, as well as those where functional complexity or repetition of task is more suited to an automated approach. Now, they are turning to the technology to help them meet emerging emissions regulations in the U.S. and Europe.

“A major development has been the rapid and increasing demand for hydraulic-hybrid propulsion systems that are highly reliant on electronic controls and software functionality to allow them to deliver better fuel savings, reduce mechanical wear, and improve emissions in conjunction with the mechanical and fluid power subsystem,” said Clyde Thomas, Senior Manager of Technical Services at Eaton.
