  • 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.

  • Patent number: 11367175
    Abstract: Provided is an in-vehicle stereo camera which enables the continuation of automated driving if failures occur during imaging. A pair of captured images 301, 302, which is captured by a pair of imaging units so that both contain an overlapping region, are acquired (S201), it is determined whether an abnormal region is present in at least one of the pair of captured images, and if an abnormal region is present, the degree of impact from the abnormal region on an object recognition process of an object recognition unit is diagnosed (S202), and the processing content of the object recognition process is updated according to the degree of impact (S203).

  • Patent number: 11093763
    Abstract: The purpose of the present invention is to provide an onboard environment recognition device exhibiting high accuracy of measurement in a wider range of view fields. The present invention pertains to an onboard environment recognition device (1) that utilizes two cameras (100, 110) for sensing, wherein the onboard environment recognition device (1) is characterized in that: two camera view fields include a stereo-vision area and a monocular-vision area; and the device laterally searches for parallax images that are output results of the stereo-vision area, estimates a road surface distance in the stereo-vision area, and measures the distance of the monocular-vision area by using the estimated road surface distance after extending the same to the monocular-vision area in the lateral direction.

  • Publication number: 20210179123
    Abstract: Fail-safe is performed appropriately when an automatic driving ECU has a failure. Provided is an in-vehicle electronic control system including a recognition device that recognizes a situation outside a vehicle, a track calculation unit that calculates a track on which the vehicle travels, a failure diagnosis unit that diagnoses a failure of the track calculation unit, and an output unit that outputs a control signal used to control the vehicle, in which a control signal generated based on a brake control instruction generated by the recognition device and a control signal generated based on a track control instruction generated by the track calculation unit are input to the output unit, and when the failure diagnosis unit diagnoses that the track calculation unit has a failure, the output unit outputs a control signal generated based on the brake control instruction generated by the recognition device.
