  • Patent number: 11292308
    Abstract: An object of the present invention is to provide a vehicle motion state estimation device capable of estimating a vertical momentum of a vehicle with high accuracy from a wheel speed sensor signal during traveling such as acceleration or deceleration, turning, or the like where wheel slips in longitudinal and lateral directions occur. The present invention estimates and removes a variation component caused by a wheel slip from variation components of a wheel speed sensor signal to extract a variation component caused by a displacement of a suspension, and estimates a vertical momentum of a vehicle from the extracted variation component caused by the displacement of the suspension.

  • Publication number: 20220073133
    Abstract: A steering control device for reducing a steering load on the driver by adjusting a gain of a rear wheel steering angle with respect to a front wheel steering angle operated by the driver according to a relative relationship between the vehicle and the parking frame to enable fine steering of the own vehicle near the parking frame when the four-wheel steering vehicle is parked. The steering control device is configured to control a rear wheel steering angle by a rear wheel steering system based on a front wheel steering angle operated by a driver, and includes an arithmetic device configured to reduce an absolute value of a gain of the rear wheel steering angle with respect to the front wheel steering angle as a positional relationship between an own vehicle and a parking frame comes closer when an own vehicle shifts to a parking driving mode.

  • Patent number: 11055474
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for locating, using a content binder library, content elements of a publisher page. For each content element, the library determines presentation attributes of the content element and at least one other library detects a mode parameter that specifies a type of user device that is requesting the publisher page. The library selects a particular content element from the publisher page as a reference point for positioning a digital component at the publisher page using the presentation attributes of the particular content element. The library determines a location of the publisher page for rendering the digital component, where the location is determined based on the reference point and the mode parameter. The library provides the digital component for display at the location of the publisher page.
