  • Patent number: 11014556
    Abstract: A driving support control unit of a driving support apparatus executes driving support control for supporting at least part of driving by a driver. A support determining unit determines whether or not predetermined conditions for terminating the driving support control are satisfied. A physical amount acquiring unit acquires a physical amount corresponding to a curviness degree of a driving lane on which an own vehicle drives. A curviness degree determining unit determines whether or not a curviness degree indicated by the physical amount acquired by the physical amount acquiring unit is smaller than a predetermined degree in the case where the predetermined conditions for terminating the driving support control are satisfied. A termination command unit commands the driving support control unit to terminate the driving support control if the curviness degree determining unit determines that the curviness degree is smaller than the predetermined degree.

  • Patent number: 10591930
    Abstract: An automatic traveling control apparatus includes an automatic traveling control unit, a function determining unit, a first notifying unit, an abnormality detecting unit, and a second notifying unit. The automatic traveling control unit makes an own vehicle automatically travel along a route to a destination. The function determining unit determines whether or not the state of a function used for automatic traveling is normal. The first notifying unit gives notification of the state of the function determined by the function determining unit. The abnormality detecting unit detects an abnormality in the notification of the state of the function by the first notifying unit. The second notifying unit gives a characteristic notification set in advance, when the abnormality detecting unit detects an abnormality in the notification of the state of the function by the first notifying unit and the function determining unit determines that the state of the function is normal.

  • Patent number: 9669461
    Abstract: Seizure resistance and wear resistance of Cu—Bi—In copper-alloy sliding material are enhanced by forming a soft phase of as pure as possible Bi. Mixed powder of Cu—In cuprous alloy powder and Cu—Bi containing Cu-based alloy powder is used. A sintering condition is set such that Bi moves outside particles of said Cu—Bi containing Cu-based powder and forms a Bi grain-boundary phase free of In, and In diffuses from said Cu—In containing Cu-based powder to said Cu—Bi containing Cu-based powder.
