Abstract: A toll advertisement message (TAM) broadcast from a roadside unit of a roadway is received. The TAM may include a public key of a toll charger cloud. Responsive to receipt of the TAM, a tolling usage message (TUM) is sent. The TUM may include information encrypted with a public key of a toll service provider, information encrypted with the public key of the toll charger cloud, and a public key of the telematics control unit. Responsive to broadcast of the TUM, a toll usage message acknowledgement (TUM-ACK message. A toll receipt message (TRM) is also received. The TRM is encrypted with the public key of the telematics control unit. The TRM is decrypted using a private key of the telematics control unit corresponding to the public key of the telematics control unit.

Abstract: In an opportunistic packet retransmission strategy, responsive to determining that a retransmission mode is set, a retransmission probability is calculated using minimum and maximum channel busy level retransmission thresholds, such that if a channel busy level of a communication channel is less than a minimum channel busy level retransmission threshold then a retransmission probability is set to 100%, if the channel busy level is greater than the maximum channel busy level then the retransmission probability is set to 0%, and within the minimum and maximum channel busy level retransmission thresholds the retransmission probability is set to decrease from 100% to 0% as a channel busy level of the communication channel rises from the minimum channel busy level retransmission threshold to the maximum channel busy level retransmission threshold. The message is retransmitted responsive to randomly determining whether to retransmit according to the retransmission probability.

Abstract: Scheduling communications using a plurality of wireless interfaces is provided. Signals are monitored that are received from a first antenna configured to send and/or receive first messages over a first message protocol. Using the signals, time slot information is updated that is indicative of which equally-sized consecutive future time slots the first antenna is predicted to transmit and/or receive the first messages. A transmission is scheduled of a second message over a second antenna configured to send and/or receive second messages over a second message protocol using the time slot information to avoid out-of-band emission (OOBE) interference.

Abstract: A first connected message is received, by a controller of a host vehicle, from a remote vehicle via a transceiver of the host vehicle. The first connected message indicates a first object along a roadway detected by the remote vehicle. Presence of a second object along the roadway is identified using sensors of the host vehicle. A probability function is utilized to determine a result indicative of whether to send a second connected message indicating the second object. The second connected message is sent responsive to the result indicating to send the second connected message. The second connected message is suppressed responsive to the result indicating not to send the second connected message.

Abstract: Smart tolling leakage prevention is provided. A TUM is stored to a TUM database, the TUM including information with respect to traversal of a vehicle along a roadway for which charges are incurred for travel. The TUM is sent, via a transceiver of the vehicle, to a road-side unit (RSU) in communication with a tolling system. A toll receipt message (TRM) is received, via the transceiver, from the tolling system. The TUM is reconciled with the TRM. A status of the reconciling is indicated.

Abstract: Vehicle-to-everything (V2X) message-based vehicle tracking is provided. Connected messages including position, dimension, and heading of remote vehicles are received from the remote vehicles and collected by a host vehicle. A route of the host vehicle is used to filter the remote vehicles to those within an interest neighborhood of the host vehicle. A map is displayed, to an HMI screen of the host vehicle, including the route of the host vehicle and an overlay of the remote vehicles as filtered.

Abstract: A road resource is identified, according to one or more maneuver sharing intent messages received to the vehicle via a transceiver of a vehicle, where the road resource is contested between the vehicle and one or more other vehicles and includes a portion of a roadway to be traversed by the vehicle and also the one or more other vehicles. A conflict resolution procedure is performed to determine whether the vehicle gains access to the road resource, wherein the conflict resolution procedure is independently performed by each of the vehicle and the one or more other vehicles. One of the vehicle or the one or more other vehicles is granted access to the road resource based on the conflict resolution procedure.

Abstract: Toll advertisement messages (TAMs) are broadcast via V2X communication, each of the TAMs indicating geographic locations of lanes of a roadway for which tolls are due and cost information for traversing the lanes of the roadway. A tolling usage message (TUM) is received via the V2X communication, the TUM indicating, to a roadside unit (RSU), information regarding a vehicle entering one of the lanes of the roadway and a unique random account identifier to be used by the RSU to identify the vehicle. A toll receipt message (TRM) is broadcast via the V2X communication, the TRM including the unique random account identifier and indicating, to the vehicle, a final cost charged to the vehicle for access to the one of the lanes of the roadway.
