  • Patent number: 10550779
    Abstract: An exhaust gas control apparatus includes a fuel injection device, a NOx occlusion reduction catalyst, a fuel addition valve, an inflow gas adjustment device, and an electronic control unit. The electronic control unit executes a low flow rate reduction treatment for removing NOx occluded in the NOx occlusion reduction catalyst after fuel supply from the fuel injection device is stopped. The electronic control unit controls the inflow gas adjustment device such that a ratio of oxygen to the fuel added to the NOx occlusion reduction catalyst at a time when a temperature of the NOx occlusion reduction catalyst is below an activation temperature becomes higher than a ratio of oxygen to the fuel added to the NOx occlusion reduction catalyst at a time when the temperature of the NOx occlusion reduction catalyst is equal to or higher than the activation temperature during the low flow rate reduction treatment.

  • Publication number: 20190383939
    Abstract: An object capturing device includes light emission, receiving, and scanning units, and distance calculation, and object determination units. The scanning unit measures light from the emission unit to head toward a measurement target space to perform scanning, and to guide reflected light from the object with respect to the measurement light to the receiving unit. The distance calculation unit calculates a distance to the object in association with a scanning angle of the scanning unit. The object determination unit determines whether the object is a capture target based on whether a scanning angle range within which a difference between distances is equal to or less than a predetermined threshold value corresponding to a reference scanning angle range of the capture target, and a determination of whether intensity distribution of the reflected light within the scanning angle range corresponds to reference intensity distribution of the reflected light from the capture target.
