Abstract: The disclosure includes implementations for providing a recommendation to a driver of a second DSRC-equipped vehicle. The recommendation may describe an estimate of how long it would take the second DSRC-equipped vehicle to receive a roadside service from a drive-through business. A method according to some implementations may include receiving, by the second DSRC-equipped vehicle, a Dedicated Short Range Communication message (“DSRC message”) that includes path history data. The path history data may describe a path of a first DSRC-equipped vehicle over a plurality of different times while the first DSRC-equipped vehicle is located in a queue of the drive-through business. The method may include determining delay time data for the second DSRC-equipped vehicle based on the path history data for the first DSRC-equipped vehicle. The delay time data may describe the estimate. The method may include providing the recommendation to the driver. The recommendation may include the estimate.

Abstract: The disclosure describes a method for an ego vehicle. The method includes receiving a vehicle-to-everything (V2X) message that describes an object that is within proximity of an ego vehicle. The method further includes generating a set of data-to-camera (D2C) filters that are specific to the object described by the V2X message. The method further includes applying the set of D2C filters to image data that describes an initial image of the object. The method further includes generating a modified image, based on applying the set of D2C filters to the image data, wherein the modified image includes an indication of (1) a location and a size of the object in the initial image and (2) a type of object in the initial image.

Abstract: The disclosure includes implementations for determining a position of a vehicle using millimeter wave narrow beamforming. A method may include receiving a set of training packets that each uniquely identify a position on a portion of a roadway where the vehicle is located. Each of the training packets included in the set may be associated with only one of the millimeter wave narrow beams. The method may include identifying a training packet included in the set of training packets that has a highest receive power level among the set of training packets. The method may include determining the position uniquely identified by the training packet having the highest receive power level. The method may include determining positional information for the vehicle based on the position uniquely identified by the training packet having the highest receive power level. The positional information may describe a location of the vehicle on the roadway.

Abstract: The disclosure includes embodiments for improving driving commands for vehicular end-to-end driving. In some embodiments, a method for a connected vehicle includes receiving command data describing one or more driving commands for the connected vehicle. The method includes correcting the one or more driving commands to generate modified command data that describes one or more modified driving commands. The one or more modified driving commands control an operation of the connected vehicle to satisfy a trajectory safety requirement. The method includes modifying an operation of a vehicle control system of the connected vehicle based on the modified command data so that the connected vehicle operates based on the one or more modified driving commands.

Abstract: The disclosure includes embodiments for matching riders to drivers for a ride sharing service based on a V2X message variable. In some embodiments, a method for a first connected device includes: receiving a first V2X broadcast message from a second connected device, where the first V2X broadcast message includes a request for the ride sharing service; determining a first V2X-message variable associated with the first V2X broadcast message; executing a ride-share matching process to match the first connected device with the second connected device based at least in part on the first V2X-message variable so that a delay of the ride-share matching process is minimized; and responsive to a completion of the ride-share matching process, modifying an operation of the communication unit to establish a secure communication between the first connected device and the second connected device for exchanging ride share information for the ride sharing service.

Abstract: The disclosure describes embodiments for reducing adjacent channel interference for wireless vehicular messages. In some embodiments, a method includes monitoring, by an onboard vehicle computer, a channel of a Vehicle-to-Everything (V2X) radio for a V2X message. The method includes determining waveform data describing a waveform that is measured on the channel by the onboard vehicle computer when monitoring the channel. The method includes determining interference data which describes an adjacent channel interference waveform which is measured on the channel by the onboard vehicle computer when monitoring the channel. The waveform includes the adjacent channel interference waveform. The method includes canceling out the adjacent channel interference waveform described by the interference data from the waveform described by the waveform data to generate digital data describing a version of the V2X message that substantially does not include the adjacent channel interference waveform, thereby reducing the adjacent channel interference for the V2X message.

Abstract: The disclosure includes embodiments for generating a real-time high-definition (HD) map for an ego vehicle using wireless vehicle data of a remote vehicle. In some embodiments, a method includes receiving a V2X wireless message which includes remote GPS data and remote road parameter data of the remote vehicle. The method includes retrieving ego GPS data of the ego vehicle. The method includes generating ego road parameter data describing an initial estimate of a geometry of a road on which the ego vehicle is located. The method includes fusing the ego road parameter data and the remote road parameter data to form fused road parameter data which describes an improved estimate of the geometry of the road that is more accurate than the initial estimate. The method includes generating a real-time HD map based on the remote GPS data, the ego GPS data, and the fused road parameter data.

Abstract: The disclosure includes a system and method for managing traffic in a roadway system based on Basic Safety Message data (“BSM data”) included in a set of Basic Safety Messages (“BSMs”). The method may include wirelessly receiving a set of BSMs describing a set of vehicles traveling along the roadway system. Each BSM included in the set of BSMs may describe a specific vehicle included in the set of vehicles, including that vehicle's lane, speed and heading of travel. The method may include analyzing the BSM data to determine whether there is an imbalance of traffic flow among a first set of vehicles traveling towards a first heading and a second set of vehicles traveling towards a second heading. The method may include determining that the bidirectional lane will be reconfigured so that traffic in the bidirectional lane flows towards the second heading based on the imbalance of traffic flow.

Abstract: The disclosure includes embodiments for improving an estimate of a geographical position of an ego vehicle using wireless vehicle data of a remote vehicle. A method according to some embodiments includes determining ego estimate data based on remote GPS data and relative position data. The remote GPS data describes a geographical location of the remote vehicle. The relative position data describes a location of the ego vehicle relative to the remote vehicle as measured by onboard sensors of the remote vehicle. The ego estimate data describes the geographical location of the ego vehicle from the perspective of the remote vehicle. The method includes fusing the ego estimate data and ego GPS data to form fused data. The ego GPS data describes the geographical location of the ego vehicle from the perspective of the ego vehicle. The fused data describes the geographical location of the ego vehicle with lane-level accuracy.
