  • Patent number: 9140500
    Abstract: When performing heat storage in a heat storage container accommodating a plurality of kinds of heat storage materials with different melting points, heat storage in the heat storage materials is performed such that a higher melting point heat storage material is in a latent heat storage state as much as possible. In other words, heat storage in the heat storage materials is performed in such a manner that the heat storage materials are in the latent heat storage state in which heat can be stored most effectively. In addition, when performing heat release from the heat storage container to heat coolant water in a circulation circuit, heat release is performed from the heat storage material in the sensible heat storage state as a priority, out of the heat storage materials. Accordingly, heat release from the heat storage container in the heat storage state is performed in such a manner that the heat storage materials are maintained in latent heat storage state for as a long period of time as possible.

  • Patent number: 9142846
    Abstract: Whether a gas leakage occurs or not is accurately determined in a simple configuration. When receiving a request for activation of a fuel cell, a control unit opens a main shutoff valve to start hydrogen gas supply from a hydrogen tank to the fuel cell. The control unit thereafter performs gas leakage determination processing for a hydrogen piping system. If it is determined in the gas leakage determination processing that a gas leakage occurs, a gas leakage alert is output to stop the activation of the fuel cell. If it is determined in the gas leakage determination processing that a gas leakage does not occur, a compressor is activated to start oxidant gas supply to the fuel cell, and the fuel cell continues being operated.

  • Patent number: 9140761
    Abstract: Each detection unit is configured to compare a voltage output from a battery cell associated therewith a predetermined criterion voltage. A plurality of detection units operate sequentially in response to a start trigger and also sequentially transmit a signal that reflects a result of comparing the voltages to detect whether a battery pack has a low cell voltage fault. A fault monitoring device detects an internal resistance fault when it receives from a transmission circuit a determination signal indicating that the battery pack when electrically discharged has any of its battery cells outputting a voltage decreased to be lower than the criterion voltage and if a current detected has a value smaller in magnitude than a criterion current corresponding to a value of a current obtained by dividing a difference in voltage between an open circuit voltage of the battery cell and the criterion voltage by an upper limit value for internal resistance.

  • Publication number: 20150259021
    Abstract: An inverted vehicle comprises a first sensor that detects an angular speed around an axis inclined from a pitch axis by a first predetermined angle, a second sensor that detects an angular speed around an axis inclined from the pitch axis by a second predetermined angle, a third sensor that detects an angular speed around the pitch axis, an acceleration detection unit that detects accelerations along the axes, and a control unit that performs the inversion control based on the detected angular speeds.

  • Publication number: 20150260280
    Abstract: Torque shares that express an exchange of torque are set as a constraint condition of an equation of motion of an automatic transmission, so it is suitable to control an exchange of torque between engagement devices, which is difficult in shift control, and it is possible to solve the equation of motion. In other words, it is possible to handle any shift pattern with the use of a predetermined shift model. Furthermore, at the time of a shift in which two elements are released and two elements are engaged, a first shift and a second shift in each of which one element is released and one element is engaged are carried out, so three control operation amounts are used in each of the first shift and the second shift, with the result that it is possible to solve the equation of motion.
