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.

The subject matter described in this specification is directed to systems and methods for dissipating heat from electronic components supporting autonomous vehicle systems. In particular, the specification describes how the electronic components can be positioned in a duct through which conditioned cabin air can be drawn to convectively dissipate heat from the electronic components.

An object-detection system for an automated vehicle includes an object-detector, a receiver, and a controller. The object-detector detects detectable-objects proximate to a host-vehicle. The receiver receives an indication of an object-presence from other-transmitters proximate to the host-vehicle. The controller is in communication with the object-detector and the receiver. The controller is configured to operate the host-vehicle to avoid interference with a hidden-object when the hidden-object is not detected by the object-detector and the object-presence is indicated by at least two instances of the other-transmitters.

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.

Detection system and method

A vehicle control system includes an object-detector, a location-detector, a configuration-map, and a controller-circuit. The object-detector is configured to detect objects proximate to a host-vehicle. The location-detector is configured to indicate a location of the host-vehicle. The configuration-map is configured to indicate a configuration of the object-detector for the location of the host-vehicle when the host-vehicle is operated in an automated-mode. The controller-circuit is in communication with the location-detector, the configuration-map, and the object-detector. The controller-circuit is configured to operate the object-detector in accordance with the configuration for the location of the host-vehicle when the host-vehicle is operated in an automated-mode, detect a human-override of the automated-mode at the location, and update the configuration-map for the location in accordance with objects detected and in response to the human-override of the automated-mode.

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.

A safe-to-proceed system () for operating an automated vehicle proximate to an intersection () includes an intersection-detector (), a vehicle-detector (), and a controller (). The intersection-detector () is suitable for use on a host-vehicle (). The intersection-detector () is used to determine when a host-vehicle () is proximate to an intersection (). The vehicle-detector () is also suitable for use on the host-vehicle (). The vehicle-detector () is used to estimate a stopping-distance () of an other-vehicle () approaching the intersection (). The controller () is in communication with the intersection-detector () and the vehicle-detector (). The controller () is configured to prevent the host-vehicle () from entering the intersection () when the stopping-distance () indicates that the other-vehicle () will enter the intersection () before stopping.

An infrastructure-device status-verification system suitable for use by an automated vehicle includes a transceiver, an object-detector, and a controller. The transceiver is suitable to install on a host-vehicle. The transceiver is used to receive an indicated-status of an infrastructure-device. The object-detector is suitable to install on the host-vehicle. The object-detector is used to determine a detected-status of the infrastructure-device. The controller is in communication with the transceiver and the object-detector. The controller determines a confirmed-status of the infrastructure-device based on the indicated-status and the detected-status. The system provides for increased confidence and security regarding information about the status of an infrastructure-device such as the traffic-signal (e.g. red, yellow, and green), thereby avoid miss-information caused by, for example, hacking or spoofing of V2I communications from the infrastructure-device, and overcome instances when the field-of-view between the object-detector and the infrastructure-devicebecomes occluded after the confirmed-status has been established or determined.

A learning system for an automated vehicle to learn local traffic customs includes a location-detector, and object-detector, and a controller. The location-detector indicates a location of a host-vehicle on a digital-map. The object-detector detects a lane-marking and other-vehicles proximate to the host-vehicle. The controller is in communication with the location-detector and the object-detector. The controller is configured to determine when an observed-behavior of the other-vehicles is not in accordance with the lane-marking present at the location, and operate the host-vehicle in accordance with the observed-behavior.

An object-detection system suitable for use in an automated vehicle includes a transceiver, and object-detector, and a controller. The transceiver is suitable to install on a host-vehicle. The transceiver is used to receive an indicated-location of an object proximate to the host-vehicle. The object-detector is suitable to install on the host-vehicle. The object-detector is used to detect a relative-location of the object relative to the host-vehicle. The controller is in communication with the transceiver and the object-detector. The controller determines a confirmed-location of the object relative to the host-vehicle based on the indicated-location and the relative-location. Determining the confirmed-location of the object allows for selecting from a variety of optimized algorithms to better track subsequent expected motion of the object, and reducing the risk of unnecessary or erratic action by the host-vehicle caused by hacking of the wireless-transmission or deliberate malicious content in the wireless-transmission.
