  • Publication number: 20210362698
    Abstract: A braking control device includes an upstream mechanism control unit, a determination unit, and a control unit. The upstream mechanism control unit is configured to feedback control the upstream mechanism in such a manner that a detected hydraulic pressure detected by a hydraulic pressure sensor is brought to an upstream target hydraulic pressure. The hydraulic pressure sensor detects a hydraulic pressure of the hydraulic pressure circuit. The determination unit is configured to determine, based on the detected hydraulic pressure by the hydraulic pressure sensor, whether hydraulic pressure hunting is occurring. The control unit is configured to control the downstream mechanism based on the upstream target hydraulic pressure and the target wheel pressure in a case where the determination unit determines that the hydraulic pressure hunting is occurring.

  • Patent number: 11180123
    Abstract: This vehicle control system is provided with an input monitoring unit and a determination time changing unit. When a state in which first target data is not input to a second control unit continues for a first determination time or longer, the input monitoring unit determines the first target data to be in a non-input state. When a state in which second target data is not input to the second control unit continues for a second determination time or longer, the input monitoring unit determines the second target data to be in a non-input state. When the first target data is determined to be in a non-input state, the determination time changing unit shortens the second determination time.

  • Publication number: 20210319218
    Abstract: An image acquisition section of an information processing apparatus acquires, from an imaging apparatus, polarization images in a plurality of orientations. A normal acquisition section of an image analysis section detects a surface of a subject by acquiring a normal vector on the basis of orientation dependence of polarization luminance. A surface assumption section assumes the presence of an undetected surface continuing from the detected surface. A subject detection section confirms whether or not the assumed surface is present using a normal vector estimated for the assumed surface. An output data generation section generates and outputs output data using information regarding the detected surface.

  • Patent number: 11108966
    Abstract: A point-of-interest information acquisition section of an information processing apparatus acquires, by using a polarization image captured from a viewpoint of an imaging apparatus, an incident plane relative to the viewpoint at a point of interest ‘a’ on a subject. A viewpoint control section determines a direction of movement of the imaging apparatus in such a manner as to suitably acquire an angle formed with the incident plane and presents the direction to a user. When the post-movement viewpoint of an imaging apparatus is determined to be appropriate, an incident plane at the point of interest ‘a’ is acquired by using the captured polarization image, and a line of intersection with the incident plane is assumed to be a normal vector n of the point of interest ‘a.
