  • Publication number: 20240069314
    Abstract: A concentrating lens includes an incident surface, an emitting surface, and a reflective surface. The incident surface includes a central portion and an outer portion. The incident surface is formed by an inner surface of a depression portion. The reflective surface surrounds the emitting surface. The reflective surface extends so as to go toward a first side as going toward an outside. A first light incident on the outer portion of the incident surface transmits through the outer portion, is reflected by the reflective surface, reflected by the incident surface, and incident on the emitting surface. A second light incident on the central portion of the incident surface transmits through the central portion and is incident on the emitting surface. The central portion of the incident surface reflects the first light reflected by the reflective surface, toward the emitting surface and transmits the second light.

  • Patent number: 11912256
    Abstract: To suppress a sharp variation in the posture of a vehicle in a control apparatus that is configured to control the posture of the vehicle by adjusting a distribution ratio of a braking force between the front and rear during braking of the vehicle. The control apparatus includes a distribution setting unit that is configured to change the braking force distribution ratio from a basic braking force ratio during braking of the vehicle so that a posture of the vehicle follows a posture indicated by the target posture value. If the target posture value is varied when the braking force distribution ratio is different from the basic braking force ratio, the distribution setting unit sets the amount of change, by which the braking force distribution ratio is changed per unit time, equal to or smaller than a restriction amount.

  • Patent number: 11908199
    Abstract: Image data captured from a traveling vehicle is considered, and it is not possible to reduce the transmission band of the image data. It is assumed that a radar 4 mounted in a traveling vehicle 10 detects a certain distant three-dimensional object at a time T in a direction of a distance d1 [m] and an angle ?1. Since the vehicle 10 travels at a vehicle speed Y [km/h], it is predicted that a camera 3 is capable of capturing the distant three-dimensional object at a time (T+?T) and an angle ?1 or at a distance d2 [m]. Therefore, if a control unit 2 outputs a request to the camera 3 in advance, so as to cut out an image of the angle ?1 or the distance d2 [m] at the time (T+?T), when the time (T+?T) comes, the camera 3 transfers a whole image and a high-resolution image being a cutout image of only a partial image, to the control unit 2.
