  • Patent number: 10373501
    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.

  • Publication number: 20190213884
    Abstract: A detection system includes a first-sensor, a second-sensor, and a controller. The first-sensor is mounted on a host-vehicle. The first-sensor detects objects in a first-field-of-view. The second-sensor is positioned at a second-location different than the first-location. The second-sensor detects objects in a second-field-of-view that at least partially overlaps the first-field of view. The controller is in communication with the first-sensor and the second-sensor. The controller selects the second-sensor to detect an object-of-interest in accordance with a determination that an obstruction blocks a first-line-of-sight between the first-sensor and the object-of-interest.

  • Publication number: 20190086529
    Abstract: A radar system for an automated vehicle includes a digital-map, a radar, and a controller. The digital-map indicates a characteristic of a roadway traveled by a host-vehicle. The radar detects objects proximate to the host-vehicle. The radar is equipped with a range-setting that is selectively variable. The controller is in communication with the digital-map and the radar. The controller is configured to select the range-setting of the radar based on the characteristic of the roadway. The characteristic may be based on speed-limit, road-shape (e.g. curve-radius), a horizon-distance, and/or an obstruction (e.g. hill, sign, or building). The radar may be equipped with a frame-rate-setting (i.e. pulse repetition frequency or PRF) that is selectively variable, and the controller may be further configured to select the frame-rate-setting based on the characteristic of the roadway.

  • Publication number: 20190041861
    Abstract: A tracking system for semi-autonomous or autonomous operation of a host vehicle is configured to detect and monitor an object. The tracking system includes an object detection device and a controller. The object detection device is mounted to the host vehicle, and is configured to detect and monitor the object, output a first detection signal indicative of the object being detected, and output a second detection signal indicative of the object not being detected. The controller is configured to receive and associate the first detection signal to a terrain slope in a common moment in time, and receive and associate the second detection signal to a change in terrain slope in a succeeding moment in time. The controller outputs a command signal causing the host vehicle to slow down upon receipt of the second signal and the change in terrain slope, both occurring in the succeeding moment in time.
