Document Type and Number:
WIPO Patent Application WO/2010/144793

Abstract:
Fault detection and response systems and processes can be used for pumps, e.g., pump/motors used in hybrid vehicles.

The response systems take appropriate action based on which fault conditions are triggered. Example fault detection systems and processes include detection systems for different types of leaks, sensor malfunctions, or operation errors.
