  • Publication number: 20210304612
    Abstract: 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.

  • Publication number: 20210289326
    Abstract: 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.

  • Patent number: 10805261
    Abstract: 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.

  • Patent number: 10491405
    Abstract: 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.

  • Patent number: 10401179
    Abstract: 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.

  • Patent number: 10319236
    Abstract: A certification tool configured to communicate with a dedicated short range communication system includes a vehicle identification unit, a message generation unit, and a communication unit. The vehicle identification unit generates unique vehicle identifications for a target number of remote vehicles. The message generation unit generates messages at a target number of transmitted messages per second for each remote vehicle, and the communication unit communicates the messages to the test vehicle to achieve a target congestion level.

  • Patent number: 9936361
    Abstract: Systems and methods for filtering received messages of a dedicated short range communications (DSRC) system are provided. A receiver module receives messages from at least one of a remote vehicle and an infrastructure system. A processing module determines at least one of a central processing unit (CPU) usage and a messages received frequency (MRF) of the DSRC system, determines a received signal strength (RSS) of a received message, determines whether the RSS of the received message is greater than a RSS threshold, and processes the received message in response to the RSS of the received message being greater than the RSS threshold. An RF filter control module adjusts an RSS threshold in response to at least one of the CPU usage being greater than a threshold CPU usage, the MRF being greater than a maximum threshold MRF, and the MRF being less than a minimum threshold MRF.
