摘要： An operation-security system for an automated vehicle includes an object-detector and a controller. The object-detector includes at least three sensors. Each sensor is one of a camera used to determine an image-location of an object proximate to a host-vehicle, a lidar-unit used to determine a lidar-location of the object proximate to the host-vehicle, and a radar-unit used to determine a radar-location of the object proximate to the host-vehicle. The controller is in communication with the at least three sensors. The controller is configured to determine a composite-location based on a comparison of locations indicated by the at least three sensors. Information from one sensor is ignored when a respective location indicated by the one sensor differs from the composite-location by greater than an error-threshold. If a remote sensor not on the host-vehicle is used, V2V or V2I communications may be used to communicate a location to the host-vehicle.

摘要： A vehicle perception sensor adjustment system includes a perception-sensor, a digital-map, and controller-circuit. The perception-sensor is configured to detect an object proximate to a host-vehicle. The perception-sensor is characterized as having a field-of-view that is adjustable. The digital-map indicates a contour of a roadway traveled by the host-vehicle. The controller-circuit in communication with the perception-sensor and the digital-map. The controller-circuit determines the field-of-view of the perception-sensor in accordance with the contour of the roadway indicated by the digital-map, and outputs a control-signal to the perception-sensor that adjusts the field-of-view of the perception-sensor.

摘要： A sensor failure compensation system for an automated vehicle includes a forward sensor, at least one side sensor, and a controller. The forward sensor is configured to monitor a forward scene and output a forward signal. The side sensor is configured to monitor a side scene and output a side signal associated with the side scene. The controller is configured to receive and process the forward signal to selectively establish a forward task in association with the forward scene, and receive and process the side signal to selectively establish a side task in association with the side scene. The controller selects the side task if the forward sensor is not functional, or selects the forward task if the side sensor is not functional.

摘要： 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.

摘要： A tire-wear detection system for an automated vehicle includes a steering-angle-sensor, a vehicle-path-detector, and a controller. The steering-angle-sensor indicates a steering-angle of a host-vehicle. The vehicle-path-detector indicates a turning-radius of the host-vehicle. The controller is in communication with the steering-angle-sensor and the vehicle-path-detector. The controller determines a wear-status of a tire of the host-vehicle based on the turning-radius and the steering-angle.

摘要： 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.

摘要： A system for semi-autonomous, or autonomous, operation of a host vehicle includes an object detector and a controller. The object detector is configured to detect an object proximate to a lane boundary and output an object signal. The controller is configured to process the object signal and direct the host vehicle away from the lane boundary upon detection of the object.

摘要： An object-classification system for an automated vehicle includes an object-detector and a controller. The object-detector may be a camera, radar, lidar or any combination thereof. The object-detector detects an object proximate to a host-vehicle. The controller is in communication with the object-detector. The controller is configured to determine a density of the object based on a motion-characteristic of the object caused by air-movement proximate to the object, and operate the host-vehicle to avoid striking the object with the host-vehicle when the density of the object is classified as dense.

摘要： 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.

摘要： A sensor failure compensation system for an automated vehicle includes first and second sensors, and a controller. The first sensor is configured to monitor a first condition and output a first signal associated with the first condition. The second sensor is configured to monitor a second condition and output a second signal associated with the second condition. The controller is configured to receive and process the first signal to establish a first reaction relative to the first condition and toward reaching a goal, receive and process the second signal to establish a second reaction relative to the second condition and toward reaching the goal, and establish a third reaction relative to the second condition and toward reaching the goal if the first sensor is malfunctioning.
