  • Patent number: 11440471
    Abstract: In one embodiment, a system perceives an environment surrounding an ADV including a vehicle in front of the ADV. The system determines whether the vehicle in front is slipping backwards based on the perception. The system determines whether the vehicle in front is situated on a road with a slope based on map information. The system determines whether a tail light or a brake light of the vehicle in front is turned on based on the perception. If it is determined that the vehicle in front is situated on a sloped road, is slipping backwards, and the tail light or the brake light is not turned on, the system calculates a time to impact or a distance to impact based on the distance and speed of the vehicle in front.

  • Patent number: 11442168
    Abstract: A vehicular driving assist system includes a plurality of lidar sensors having respective fields of sensing exterior the vehicle, with the fields of sensing of first and second lidar sensors partially overlapping at an overlap region. The lidar sensors emit a respective pattern of light and provide a respective output to an ECU based on sensed light that is reflected by objects present in the field of sensing of the respective lidar sensor. The pattern of light emitted by the second lidar sensor differs from the pattern of light emitted by the first lidar sensor. The ECU determines misalignment of the second lidar sensor relative to the first lidar sensor based at least in part on the light sensed by each of the lidar sensors that is reflected by an object present in the overlap region when the respective pattern of light is emitted by the respective lidar sensor.

  • Patent number: 11420627
    Abstract: A driving assistance device is configured to perform deceleration control in such a way that a vehicle stops at a target position determined by a deceleration target ahead of the vehicle. The driving assistance device is configured to calculate a predicted vehicle speed of the vehicle at the target position when the deceleration control is performed, based on the current vehicle speed of the vehicle, the distance to the target position, and the deceleration that varies depending on the type of the deceleration target. When the predicted vehicle speed is higher than a predetermined value, the driving assistance device is configured not to perform the deceleration control or to reduce the deceleration in the deceleration control.

  • Patent number: 11402848
    Abstract: A collision-avoidance system for use with an autonomous-capable vehicle can continuously receive image frames captured of the roadway to determine drivable space in a forward direction of the vehicle. The system can determine, for each image frame, whether individual regions of the image frame depict drivable space. The system can do so using machine-learned image recognition algorithms such as convolutional neural networks generated using extensive training data. Using such techniques, the system can label regions of the image frames as corresponding to drivable space or non-drivable space. By analyzing the labeled image frames, the system can determine whether the vehicle is likely to impact a region of non-drivable space. And, in response to such a determination, the system can generate control signals that override other control systems or human operator input to control the brakes, the steering, or other sub-systems of the vehicle to avoid the collision.

  • Patent number: 11402221
    Abstract: Some embodiments provide an autonomous navigation system which enables autonomous navigation of a vehicle along one or more portions of a driving route based on monitoring, at the vehicle, various features of the route as the vehicle is manually navigated along the route to develop a characterization of the route. The characterization is progressively updated with repeated manual navigations along the route, and autonomous navigation of the route is enabled when a confidence indicator of the characterization meets a threshold indication. Characterizations can be updated in response to the vehicle encountering changes in the route and can include a set of driving rules associated with the route, where the driving rules are developed based on monitoring the navigation of one or more vehicles of the route. Characterizations can be uploaded to a remote system which processes data to develop and refine route characterizations and provide characterizations to one or more vehicles.

  • Patent number: 11380203
    Abstract: Recent location and control information received from “lead” vehicles that traveled over a segment of land, sea, or air is captured to inform, via aggregated data, subsequent “trailing” vehicles that travel over that same segment of land, sea, or air. The aggregated data may provide the trailing vehicles with annotated road information that identifies obstacles. In some embodiments, at least some sensor control data may be provided to the subsequent vehicles to assist those vehicles in identifying the obstacles and/or performing other tasks. Besides, obstacles, the location and control information may enable determining areas traveled by vehicles that are not included in conventional maps, as well as vehicle actions associated with particular locations, such as places where vehicles park or make other maneuvers.
