  • Fault detection and mitigation in hybrid drive system
    Patent number: 10030648
    Abstract: 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.
    Type: Grant
    Filed: February 9, 2015
    Date of Patent: July 24, 2018
    Assignee: Eaton Intelligent Power Limited
    Inventors: Michael Anthony Stoner, Thomas D. Hawkins, Douglas D. Simpson
