The disclosure includes embodiments for executing a beam alignment for a millimeter wave (mmWave) communication based on position data. In some embodiments, a method for an ego vehicle includes determining a beam sweeping direction setting for a mmWave beam alignment with an endpoint based on position data that describes a geographic location of the endpoint. The method includes modifying an operation of a Vehicle-to-Everything (V2X) radio of the ego vehicle to perform the mmWave beam alignment with the endpoint based on the beam sweeping direction setting so that an efficiency of the mmWave beam alignment is improved.

Systems and methods for scheduling environment perception-based data offloading for numerous connected vehicles are disclosed. In one embodiment, a method for offloading data includes capturing an image of a view of interest from a vehicle, segmenting the image into a plurality of blocks, and determining a scheduling priority for each of one or more blocks among the plurality of blocks based on block values, wherein the block values relate to one or more objects of interest contained in each of the one or more blocks. The method further includes offloading, from the vehicle to a server, one or more blocks based on the scheduling priority of the one or more blocks.

Systems and methods for scheduling environment perception-based data offloading for numerous connected vehicles

A method for measuring a distance is provided. The method includes receiving a fine time measurement (FTM) message, extracting channel state information (CSI) from the FTM message, determining with a channel condition classifier a probability that the FTM message is multi-path based on the corresponding CSI, and discarding the FTM message in response to the probability that the FTM message is multi-path is above a threshold level of probability.

Methods, systems, and non-transitory mediums for augmented fine time measurement

System, methods, and embodiments described herein relate to dynamically generating a wide field-of-view three-dimensional pseudo point cloud of an environment around a vehicle. A disclosed method may include capturing, via a camera, a first view in a first image, determining a first depth map based on the first image, obtaining, from an external system, a second image of a second view that overlaps the first view and a second depth map based on the second image, inputting the first image and the second image into a self-supervised homograph network that is trained to output a homographic transformation matrix between the first image and the second image, and generating a three-dimensional pseudo point cloud that combines the first depth map and the second depth map based on the homographic transformation matrix.

Cooperative pseudo point cloud for connected vehicles

Systems and methods are provided for utilizing sensor data from sensors of different modalities and from different vehicles to generate a combined image of an environment. Sensor data, such as a point cloud, generated by a LiDAR sensor on a first vehicle may be combined with sensor data, such as image data, generated by a camera on a second vehicle. The point cloud and image data may be combined to provide benefits over either data individually and processed to provide an improved image of the environment of the first and second vehicles. Either vehicle can perform this processing when receiving the sensor data from the other vehicle. An external system can also do the processing when receiving the sensor data from both vehicles. The improved image can then be used by one or both of the vehicles to improve, for example, automated travel through or obstacle identification in the environment.

Systems and methods of cooperative depth completion with sensor data sharing

The disclosure includes embodiments for processing a set of wireless messages by an ego vehicle. A method includes determining a location of an object of interest in a roadway environment that includes the ego vehicle and a set of remote connected vehicles. The method includes segmenting the roadway environment into a plurality of segments. The method includes assigning priority scores to each of the segments based on (1) whether the forward-facing sensors of the remote connected vehicles present in the segment are capable of measuring the object of interest and (2) proximity of the remote connected vehicles in the segment to the object of interest, wherein segments have higher priority scores if the remote connected vehicles present in the segment have forward-facing sensors that are capable of measuring the object of interest and the remote connected vehicles present in the segment are closer to the object of interest.

Message processing for wireless messages based on value of information

An airbag device equipped in a vehicle seat. The vehicle seat has a structure in which a seat frame is arranged with left and right sides inside the seat back. The airbag device according to the present invention includes: an inflator that is secured to the side of the seat frame of the vehicle seat and an airbag that is stowed inside the seat back in an elongated and compressed state and is expanded and deployed by the expansion gas discharged from the inflator. The airbag in the stowed state is arranged along the seat frame, and includes a lower portion area lower than the inflator and an upper portion area above the inflator. The lower portion area is arranged inside the seat frame, and the upper portion area is arranged outside the seat frame.

A message can be received from a first object. The message can include information about a position of the first object. An electromagnetic energy can be caused to be transmitted in a direction of the first object at a time in which the first object is in motion. A reflection of the electromagnetic energy can be received from the direction of the first object. A first possible position of a second object can be determined based on the reflection of the electromagnetic energy having traveled entirely along a path defined by a line formed by the first object and the vehicle. A second possible position of the second object can be determined based on the reflection of the electromagnetic energy having traveled along a path outside of the line. An actual position of the second object being the second possible position of the second object can be determined.

The disclosure describes embodiments for modifying a vehicle component of an ego vehicle based on ranging and misbehavior information determined from digital data included in a Vehicle-to-Everything (V2X) message. In some embodiments, a method includes generating Received Signal Strength (RSS) data describing an RSS value for the V2X message which is originated by a remote vehicle. The method includes determining range data corresponding to the RSS value describing a first range from the ego vehicle to the remote vehicle. The method includes determining that the remote vehicle is providing inaccurate sensor data (an example of misbehavior information) by comparing the first range to a second range which is described by the sensor data which is extracted from the V2X message. The method includes modifying an operation of the vehicle component so that the vehicle component does not consider the sensor data that is provided by the remote vehicle.
