Publication number: 20120035802Abstract: A learning diagnostic system for a working machine is capable of making a fault diagnosis of the working machine universally relative to various types of sensor information, and preventing a failure in the working machine by enabling a fault diagnosis even in a transient operating state that represents a transitional state between operating states. A state learning device 201 sorts inputted sensor data 101a into one under a steady operating state and one under a transient operating state, and generates, through learning, steady state data 102a and intermediate state data 103a, each including a permissible error. A state diagnostic device 202 uses the steady state data 102a to determine whether an operating state of the working machine related to the inputted sensor data is the steady operating state or the transient operating state, and make a fault determination in the steady operating state.Type: ApplicationFiled: February 19, 2010Publication date: February 9, 2012Inventors: Hideaki Suzuki, Yoshinori Furuno, Kenji Araki, Kozo Nakamura, Shinya Yuda, Hirotaka Takahashi

Patent number: 8054045Abstract: In a status detector for a power supply, a power supply, and an initial characteristic extracting device for use with the power supply, a measuring unit obtains measured values of at least current, voltage and temperature of the electricity accumulating unit. A processing unit executes status detection of the electricity accumulating unit by using the measured values and the characteristic information of the electricity accumulating unit which is stored in a memory unit. A discrepancy detecting unit detects the presence of a discrepancy away from a theoretical value when a result of the status detection is changed over a predetermined threshold or reversed with respect to the measured values. A modifying unit modifies the characteristic information depending on the detected discrepancy.Type: GrantFiled: October 13, 2009Date of Patent: November 8, 2011Assignee: Hitachi Vehicle Energy, Ltd.Inventors: Youhei Kawahara, Akihiko Emori, Shuko Yamauchi, Hirotaka Takahashi, Masami Shida, Akihiko Kudo
