Abstract
Official abstract text for this publication.
Fault detection and response systems and processes can be used for pumps, e.g., pump/motors used in hybrid vehicles. The fault detection systems determine when certain operating conditions, which may affect the proper operation of the system, occur. 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A limit method for limiting a speed of an engine of a vehicle having a first power source and a second power source, the method comprising: determining that the vehicle has failed to disengage the second power source from the engine; obtaining a pump speed of a pump of the second power source; obtaining a gear ratio of the pump of the second power source; determining a maximum allowable pump speed based at least partially on the gear ratio; and…
