  • Patent number: 11933025
    Abstract: Each time clogging of a filter (5) of an air cleaner is determined on the basis of intake negative pressure of an engine (2), and the air filter (5) is cleaned, an accumulated value of operating time of the engine (2) from previous cleaning until clogging is determined is taken as a cleaning interval (S), and sequentially measured. A plurality of stages are previously set by classifying a minimum value and a maximum value of the cleaning interval (S), and the measured cleaning interval (S) is added to the stage to which the measured cleaning interval (S) is to belong, among the stages. A histogram in which an axis of abscissas is taken as the stage, an axis of ordinates is taken as frequency of the cleaning interval (S) is constructed, and an approximate straight line (L2) illustrated by a solid line is obtained by approximating a characteristic line (L1) of the histogram illustrated by a dotted line to a straight line.

  • Patent number: 9865167
    Abstract: A traffic control assisting system (“assisting system”) stores action data on an action of a moving object, geographic data in which geographic attribute information, which is information on a reference of movement of the moving object, is imparted to individual segments that are meshes into which a map is divided, and responsiveness data on the moving object's responsiveness to an instruction. The assisting system estimates an ideal action of the moving object based on the responsiveness data; calculates a difference between the estimated action and an action in the action data; updates the responsiveness data based on a result of the calculation; estimates probability of presence of the moving object at certain coordinates at each time point based on the action data, the geographic data, and the responsiveness data and generates a geographic E map; and predicts future coordinates of the moving object based on the geographic E map.
