  • Publication number: 20200175876
    Abstract: A system for operating an automated vehicle in a crowd of pedestrians includes an object-detector, optionally, a signal detector, and a controller. The object-detector detects pedestrians proximate to a host-vehicle. The signal-detector detects a signal-state displayed by a traffic-signal that displays a stop-state that indicates when the host-vehicle should stop so the pedestrians can cross in front of the host-vehicle, and displays a go-state that indicates when the pedestrians should stop passing in front of the host-vehicle so that the host-vehicle can go forward. The controller is in control of movement of the host-vehicle and in communication with the object-detector and the signal-detector. The controller operates the host-vehicle to stop the host-vehicle when the stop-state is displayed, and operates the host-vehicle to creep-forward after a wait-interval after the traffic-signal changes to the go-state when the pedestrians fail to stop passing in front of the host-vehicle.

  • Patent number: 10366294
    Abstract: An object classification system for an automated vehicle includes a lidar and/or a camera, and a controller. The controller determines a lidar-outline and/or a camera-outline of an object. Using the lidar, the controller determines a transparency-characteristic of the object based on instances of spot-distances from within the lidar-outline of the object that correspond to a backdrop-distance. Using the camera, the controller determines a transparency-characteristic of the object based on instances of pixel-color within the camera-outline that correspond to a backdrop-color. The transparency-characteristic may also be determined based on a combination of information from the lidar and the camera. The controller operates the host-vehicle to avoid the object when the transparency-characteristic is less than a transparency-threshold.
