Abstract: A full speed range adaptive cruise control system for a vehicle that stops at an intersection includes one or more controllers that execute instructions to receive localization data and situational data related to the vehicle. The one or more controllers determine, based on localization data and situational data, that the vehicle is approaching an intersection and will come to a stop at the intersection, where the vehicle is part of a queue including one or more surrounding vehicles. In response to determining the vehicle has come to a stop, the controller determines a position of the vehicle within the queue and an overall length of the queue. The controller calculates an adaptive launch time based on at least the position of the vehicle within the queue, the overall length of the queue, the situational data, and a timing delay associated with the queue.

Abstract: An attention-driven streaming system includes an adaptive-streaming module and a transceiver. The adaptive-streaming module includes filters, a compression module, an attention-driven strategy module and a fusion module. The filters filter sensor data received from sensors of a vehicle. The compression module compresses the filtered sensor data to generate compressed data. The attention-driven strategy module generates feedforward information based on a state of the vehicle and a state of an environment of the vehicle to adjust a region of interest. The fusion module generates an adaptive streaming strategy to adaptively adjust operations of each of the filters. The transceiver streams the compressed data to at least one of an edge computing device or a cloud-based network device and in response receive feedback information and pipeline monitoring information. The fusion module generates the adaptive streaming strategy based on the feedforward information, the feedback information and the pipeline monitoring information.

Abstract: A method in a vehicle includes receiving a vehicle-to-infrastructure (V2I) message transmitted from a communication system affixed to infrastructure at a location. The V2I message includes at least one category of information among a plurality of categories of information and the plurality of categories of information include map-based information and road safety information. The method also includes determining, based on performing at least one type of verification, whether a misbehavior has occurred with respect to the V2I message. The misbehavior indicates incorrect information in the V2I message. A counter is maintained of a number of times the misbehavior has occurred with respect to the V2I message at the location, and the misbehavior is reported based on the counter.

Abstract: A method includes approaching, with a vehicle, first stretch of road having a reference target. Next, data is obtained regarding the first stretch of road from both an onboard vehicle sensor and an infrastructure signal provided about the reference target. The information from the vehicle sensor is compared to the information from the infrastructure signal. Finally, the vehicle sensor is calibrated based on the infrastructure signal.

Abstract: A system for analyzing driver fitness to drive with consideration given to any of various conditions such as driver drowsiness, fatigue, and anxiety. The system includes a processing hardware unit, and a non-transitory computer-readable storage device comprising various modules to determine if the driver is impaired. The modules include an input interface module that, when executed by the processing unit, receives sensor data indicating a present driver health factor. A database module includes pre-established driver-profile data particular to a driver. And the modules include an activity module that, when executed by the processing unit, obtains the driver-profile data and the sensor data, and determines, based on the present health factor and the pre-established driver-profile data, fitness of the driver to drive. The disclosure relates in various embodiments to a computer-readable storage device, separately, and processes performed by the system and device.

Abstract: A method of determining the position of a vehicle includes generating a vehicle-based point cloud of objects in proximity to the vehicle, referenced to a vehicle-based coordinate system. The method also includes receiving an infrastructure-based point cloud, referenced to a global coordinate system, of objects detected by a camera mounted at a fixed location external to the vehicle, and registering the vehicle-based point cloud with the infrastructure-based point cloud to determine the vehicle position in the global coordinate system.

Abstract: An infrastructure-supported perception system for connected vehicle applications includes one or more infrastructure perception sensors that capture perception data having a reduced resolution and a reduced frame rate. The reduced resolution includes a reduced number of pixels for a given frame when compared to a standard resolution and the reduced frame rate captures data at a lower rate when compared to a standard frame rate. The infrastructure-supported perception system includes one or more controllers that are part of a connected vehicle. The controllers of the connected vehicle are in wireless communication with the one or more infrastructure perception sensors and one or more servers, and the one or more servers are in wireless communication with the one or more infrastructure perception sensors. The controllers receive dynamic information regarding one or more detected objects in an environment surrounding the connected vehicle from the one or more servers.

Abstract: A method includes obtaining information about a lead vehicle. The lead vehicle is traveling directly ahead of the host vehicle and the information includes velocity of the lead vehicle and a gap g between the host vehicle and the lead vehicle. Based on detecting a change in the velocity of the lead vehicle in the information, a corresponding desired acceleration is computed for the host vehicle using perceived acceleration of the lead vehicle to maintain the gap g within a specified range of gap values. The perceived acceleration of the lead vehicle is based on the change in the velocity indicated by the information. Based on a check of parameters involved in the computing the corresponding desired acceleration, a modified desired acceleration is computed for the host vehicle using a lag for the lead vehicle that results in an intended acceleration of the lead vehicle differing from the perceived acceleration.

Abstract: A vehicle system is provided for correcting in real-time a camera-based estimated position of a road object. The system includes a camera for generating an image input signal including image sensor data associated with the road object. The system further includes one or more input devices for generating a vehicle input signal including vehicle sensor data associated with a position, a speed, and a heading of the vehicle. The system further includes a computer, which includes one or more processors and a non-transitory computer readable medium (CRM) storing instructions. The processor is programmed to match the image sensor data and the vehicle sensor data to one another based on a common time of collection. The processor is further programmed to determine an error model and a deviation of a current camera-based position from a predicted position. The processor is further programmed to update the error model based on the deviation.
