Abstract: Technical solutions are described for generating a pedestrian detection warning in a vehicle. An example method includes constructing, by a vehicle controller, a pedestrian zone based on pedestrian information that is received from a traffic controller. The method further includes computing, by the vehicle controller, a vehicle trajectory that predicts a path for the vehicle. The method further includes determining, by the vehicle controller, a minimal distance between the pedestrian zone and the vehicle trajectory. The method further includes predicting, by the vehicle controller, a time to collision by computing a time for the vehicle to reach a location corresponding to the minimal distance along the vehicle trajectory. The method further includes in response to the time to collision being below a threshold, generating, by the vehicle controller, a warning for an operator of the vehicle.

Abstract: A method includes approaching, with a vehicle, first stretch of road having a reference target. Next, data is obtained regarding the first stretch of road from both an onboard vehicle sensor and an infrastructure signal provided about the reference target. The information from the vehicle sensor is compared to the information from the infrastructure signal. Finally, the vehicle sensor is calibrated based on the infrastructure signal.

Abstract: A method includes identifying a reference target with both a vehicle sensor and an infrastructure position signal. A position of a host vehicle with respect to the reference target is then determined. A localized position error between the host vehicle position and the determined position with respect to the object is then calculated with a vehicle controller. Finally, a vehicle positioning system is compensated to account for the localized position error.

Abstract: A communication system that determines a context and an intent of a specific remote vehicle located in a surrounding environment of a host vehicle includes one or more controllers for receiving sensed perception data including sensed perception data. The one or more controllers execute instructions to determine a plurality of vehicle parameters related to the specific remote vehicle. The the one or more controllers execute instructions to associate the specific remote vehicle with a specific lane of travel of a roadway based on map data. The one or more controllers determines possible maneuvers, possible egress lanes, and a speed limit for the specific remote vehicle for the specific lane of travel based on the map data, and determines the context and the intent of the specific remote vehicle based on the plurality of vehicle parameters, the possible maneuvers, the possible egress lanes for the specific remote vehicle, and the speed limit related to the specific remote vehicle.

Abstract: A supplier network device is provided and includes a supplier processor and memory that stores a credential package including information for a chip or a vehicle control module (VCM). The supplier processor: receives ID and signature public keys from the chip, where the ID and signature public keys correspond respectively to private keys stored in the chip; transmit the ID and signature public keys to a certificate authority processor of a vehicle manufacturer data center; and receive the credential package including signing certificates from the certificate authority processor prior to assembling the VCM. The supplier processor: reads the ID public key from the VCM subsequent to incorporating the chip in the VCM; identifies the credential package based on the ID public key; and based on the identifying of the credential package, programs the VCM with the signing certificates prior to installation of the vehicle control module in a vehicle.

Abstract: A method of determining the position of a vehicle includes generating a vehicle-based point cloud of objects in proximity to the vehicle, referenced to a vehicle-based coordinate system. The method also includes receiving an infrastructure-based point cloud, referenced to a global coordinate system, of objects detected by a camera mounted at a fixed location external to the vehicle, and registering the vehicle-based point cloud with the infrastructure-based point cloud to determine the vehicle position in the global coordinate system.
