  • Patent number: 10210407
    Abstract: A traffic signal detection device includes a narrow-angle camera, a wide-angle camera having an angle of view wider than the narrow-angle camera, and a traffic signal detector configured to detect a traffic signal from at least any of a narrow-angle image captured by the narrow-angle camera and a wide-angle image captured by the wide-angle camera. The traffic signal detector selects, as a detection result, any of a traffic signal detected from the narrow-angle image and a traffic signal detected from the wide-angle image, on the basis of a deceleration start region in which a vehicle should start deceleration, the deceleration start region calculated from a position of a traffic signal with respect to the vehicle and a speed of the vehicle in order to stop the vehicle at a stop position with respect to the traffic signal.

  • Publication number: 20190040830
    Abstract: An object of a control method to control a direct injection internal combustion engine that directly injects fuel in a cylinder is to reduce an increase in PN caused by attachment of the fuel to a fuel injection valve distal end. The control method cools the fuel before a fuel temperature when the fuel passes through an injection hole on a fuel injection valve reaches a temperature at which an amount of attached fuel to the fuel injection valve distal end increases.

  • Patent number: 10198950
    Abstract: A parking assist method for assisting parking of a subject vehicle uses a parking assist apparatus comprising a controller that guides the subject vehicle to a parking space and a display that displays the parking space. The parking assist method comprises: specifying an available parking space into which the subject vehicle can be parked; displaying the available parking space on the display; when the available parking space is in a parking-unavailable state that represents a state in which the subject vehicle cannot be parked into the available parking space, determining whether or not the parking-unavailable state is canceled; and when the parking-unavailable state is canceled before a first time passes, maintaining a display form of the available parking space on the display.
