  • Patent number: 10589787
    Abstract: It is an object of the present invention to provide a power steering apparatus control device in which it is possible to suppress generation of the canceling of the automatic steering unintended by the driver. The present invention provides a control device controlling the operation of a power steering apparatus in which there is selected either an assist control (28) in which a steering force is assisted based on a steering torque input through the operation of a steering wheel or an automatic steering control (29) in which a steering angle of a turning wheel is controlled based on a steering angle command value. When, in the state in which the automatic steering control (29) is selected, the steering torque exceeds a predetermined threshold value, the automatic steering control (29) is canceled and the assist control (28) is selected.

  • Patent number: 10511283
    Abstract: A surface acoustic wave filter includes resonators, wherein one of the resonator includes four or more regions with different pitches of electrode fingers, the pitch of electrode fingers in each of the four or more regions is constant, the pitch of electrode fingers in first regions, among the four or more regions, disposed at both ends of the resonator in a surface acoustic wave propagation direction is smaller than the pitch of electrode fingers in the regions other than the first regions, and the pitch of electrode fingers in a second region adjacent to the first region and the pitch of electrode fingers in a third region adjacent to the first region are different from each other.

  • Patent number: 10493985
    Abstract: In the present invention, it is possible to accurately predict, at an earlier timing, that a pedestrian will perform constant speed movement or a route change that is more complex than the constant speed movement. Provided is a travel control device that can accurately determine a change in the route of the pedestrian according to a change in the pedestrian's posture and, in particular, a change in the orientation of the body or a change in an inverted angle, and that can appropriately control the travel of the vehicle.

  • Patent number: 10026318
    Abstract: A vehicle drive control apparatus includes: an object detection unit which detects positions, speeds, and sizes of objects around an own vehicle; and a speed control unit which detects a moving object existing in a place adjacent to a scheduled travelling path of the own vehicle and a speed change induction obstacle inducing a future speed vector change of the moving object from the objects detected by the object detection unit and changes a speed of the own vehicle, on the basis of a relative position relation of the own vehicle and the detected moving object and the speed change induction obstacle.
