A path prediction system includes a transceiver, a memory and a control module. The transceiver is configured to receive a map message at a host vehicle, the map message comprising path information of vehicles through an intersection. The memory is configured to store map data including global navigation satellite system information. The control module is configured to (i) determine if the host vehicle is approaching, at or in an intersection based on the map data, (ii) in response to determining that the host vehicle is approaching, at or in the intersection, predict a path of the host vehicle through the intersection based on the path information, and (iii) based on the predicted path of the host vehicle, perform at least one collision warning operation.

Path prediction based on intersection information from map messages

A remote station includes a transceiver, a memory and a control module. The memory is configured to store (i) baseline static paths of vehicles moving through an intersection, and (ii) map data. The control module is configured to obtain road obstruction information, based on the baseline static paths and the map data, determine whether the road obstruction information affects one or more of the baseline static paths of the vehicles through the intersection and update the one or more baseline static paths based on the road obstruction information, and broadcast, via the transceiver, a map message indicating the updated one or more baseline static paths.

Intersection-based offboard vehicle path generation

A roll-over alert system for a vehicle when navigating a curve in a road. The system includes a transceiver, a memory, and a control module. The transceiver is configured to receive a map message including a general curve speed recommendation for the curve. The memory is configured to store the map message and vehicle-specific data relevant to safely navigating the curve. The control module is configured to: (i) calculate a vehicle-specific curve speed based on the vehicle-specific data and the general curve speed recommendation included in the map message; and (ii) generate an alert to an operator of the vehicle when an actual vehicle speed exceeds the vehicle-specific curve speed during navigation of the curve by the vehicle.

V2-based roll-over alert in an intersection

A system for generating virtual lane markers of an intersection so that the virtual lane markers are visible to an operator of a vehicle at the intersection. The system includes a remote station having a transceiver, a remote memory module configured to store map data and baseline static paths of vehicles moving through the intersection, and a remote control module configured to broadcast via the transceiver a map message indicating the baseline static paths. A vehicle transceiver is configured to receive the map message. A vehicle control module is configured to generate virtual lane markers through the intersection based on the baseline static paths included with the received map message.

Lane monitoring during turns in an intersection

A method for broadcasting a basic safety message (BSM) packet from a host vehicle includes storing at least one path history entry of the host vehicle. The method includes determining whether a global navigation satellite system (GNSS) position fix is available. The method includes performing a corrective action on the at least one path history entry in response to the GNSS position fix not being available. The method includes, in response to the GNSS position fix being available, calculating a path history entry to be stored among the at least one path history entry based on the GNSS position fix. The method includes generating and broadcasting the BSM packet based on the at least one path history entry.

Methods and systems for transmitting basic safety messages

A method for broadcasting a basic safety message (BSM) packet from a host vehicle includes receiving sensor data from one or more vehicle sensors provided at the host vehicle. The method includes determining whether the sensor data indicates a lane change of the host vehicle. The method includes performing a corrective action on at least one path history entry that is stored in a database in response to the sensor data indicating the lane change. The method includes generating and broadcasting the BSM packet based on the at least one path history entry.

An emergency communication system for a vehicle. The system includes a drone docking station configured to be mounted to a vehicle. An aerial drone is configured to be docked to the docking station and released from the docking station when the vehicle is disabled and/or a driver is incapacitated at a location that is out of range of communication with emergency authorities.

Emergency communications system for vehicle

The present disclosure provides an apparatus mounted on a host vehicle to detect a duplicate temporary ID in basic safety messages (BSMs). The apparatus includes a receiver and a duplicate identifier. The receiver is configured to receive the BSMs from surrounding vehicles through packet transmission. The duplication identifier configured to identify the duplicate temporary ID based on the BSMs having an identical temporary ID value commonly used by at least two surrounding vehicles. A locator is configured to detect a location for each of the packets based on locational information. An absolute distance calculator is configured to calculate an absolute distance between the locations for two successive packets. The duplication identifier is configured to identify the duplicate temporary ID when the absolute distance calculated by the absolute distance calculator is greater than an absolute distance threshold.

Apparatus for detecting duplicate temporary ID

A vehicle communications system includes a pair of antennas, a radio, and a controller. The controller is configured to enable and disable antenna diversity between communication over a safety channel and communication over a service channel.

Intelligent antenna system

Systems and method for using a single dedicated short range communication (DSRC) radio of a vehicle to receive basic safety messages (BSMs) and to communicate with an internet server. The method includes the following: transmitting and receiving BSMs with the single DSRC radio of the vehicle on a safety channel; receiving with the DSRC radio on the safety channel an advertisement transmitted by road-side equipment, the advertisement regarding internet connectivity to a server; and establishing a connection between a vehicle communication module of the vehicle and the server with the DSRC radio in accordance with the advertisement.

Systems and methods for cryptographic security verification include receiving, using a dedicated short range communications system, a message from a remote vehicle or an infrastructure system. A processor determines whether a current number of attempted message verifications per second is less than a predetermined threshold. The processor performs verification of the message in response to determining that the current number of attempted message verifications per second is less than the threshold. The processor determines whether the message falls within at least one predetermined category of message type and performs verification of the message in response to the current number of attempted message verifications per second not being less than the threshold and the message falling within the at least one predetermined category of message type. The processor processes the message in response to the message being verified.

Cryptographic security verification of incoming messages

A system for detecting inaccuracies in a global network satellite system receiver or a global positioning system receiver within a vehicle includes a global network satellite system receiver or a global positioning system receiver, an average position and standard deviation determination unit, an inaccuracy determination unit, and a vehicle controller. The global network satellite system receiver or global positioning system receiver receives a signal indicating a current position of a vehicle. The average position and standard deviation determination unit determines an average position and a standard deviation for a position of the vehicle. The inaccuracy determination unit determines whether the standard deviation for the position is greater than a standard deviation threshold. The vehicle controller adjusts safety applications of one of the vehicle or a remote vehicle if the standard deviation for the position is greater than the standard deviation threshold.
