  • Publication number: 20180233920
    Abstract: In a solar power generation control device, a memory stores an output voltage at which maximum power is obtained, for each illuminance on a panel surface of a solar panel, acquisition circuitry acquires a vehicle speed, a present illuminance on the panel surface, and first information indicating an illuminance in a prescribed area ahead of a vehicle, and calculation circuitry calculates a predicted illuminance on the panel surface, which is an illuminance after a lapse of a prescribed length of time, based on the first information and the vehicle speed. When determining that an absolute value of a difference between first and second output voltages, at which maximum powers are obtained respectively at the present and predicted illuminances, exceeds a prescribed threshold, control circuitry makes correction such that an output voltage of the solar panel coincides with the second output voltage upon the lapse of the prescribed length of time.

  • Publication number: 20180233756
    Abstract: A shutoff valve, a first gas pressure sensor, a pressure reducing valve, a second gas pressure sensor, and a gas supply component are provided, sequentially from a gas tank side, in a gas supply flow channel that extends from the gas tank to a gas consuming component. Besides, a buffer tank is provided, via an on-off valve, in a branch flow channel that branches off from the gas supply flow channel between the pressure reducing valve and the gas supply component. This buffer tank is in a situation where the pressure of the buffer tank is not higher than a consumption prescribed gas pressure. In calibrating the first gas pressure sensor, with the shutoff valve closed and with the on-off valve open, a detection value of the first gas pressure sensor is calibrated through the use of a detection value of the second gas pressure sensor.

  • Publication number: 20180230918
    Abstract: An operating range boundary for switching a cam for driving an intake valve (drive cam) is changed in a direction of increasing an engine load if a target EGR rate is predicted to increase across the contour line shown in FIG. 3 during an acceleration operation. As can be seen from comparing FIG. 6 and FIG. 7, a switching boundary in FIG. 7 is changed in a higher load direction than that in FIG. 6. By changing to such a high load direction, a range in which a large cam is selected is enlarged. That is, switching of the drive cam from the large cam to a small cam is delayed. Therefore, it is possible to suppress deterioration of the combustion state in the cylinder.
