  • Patent number: 9683861
    Abstract: An estimated route presentation apparatus including a control device is provided. The control device executes an image acquisition function to acquire a captured image captured by a camera provided on the vehicle, an estimated route calculation function to: detect an end part of a diagram displayed on a road surface from an image of the road surface included in the captured image; obtain a center of gyration of the vehicle traveling, on the basis of changes in the direction and distance of the movement of the end part as the vehicle travels; and calculate an estimated route of the vehicle with reference to the center of gyration, and a presentation control function to present the calculated estimated route.

  • Publication number: 20160227098
    Abstract: An information presentation system comprising a control device is provided. The control device executes an image acquisition function to acquire a captured image around a vehicle captured by an onboard camera, a delay state determination function to determine a delay state using a delay time of wireless communication between an onboard apparatus and a terminal apparatus, a predicted image generation function to calculate a position of the vehicle after the delay time on a basis of state information of the vehicle and generate a predicted image using the captured image that has been acquired so as to predict the predicted image to be captured by the camera at the calculated position of the vehicle and a presentation function to present the predicted image.

  • Patent number: 8947259
    Abstract: A vehicle wrong-way travel detection device includes a map information storage unit where map information is stored, a decision-making point setting unit that sets, based upon the map information stored in the map information storage unit, the connecting point located ahead along a subject vehicle traveling direction as a decision-making point, a wrong-way travel decision-making area setting unit that sets wrong-way travel decision-making areas for at least one of a plurality of roads connected to the decision-making point, and a wrong-way travel decision-making unit that makes a decision, based upon the direction of traffic flow set for a unidirectional traffic road connected to the decision-making point and the subject vehicle traveling direction, as to whether or not the subject vehicle is traveling against the flow of traffic on the unidirectional traffic road.
