Abstract:
A method and apparatus for use in traversing a vehicle transportation network may include determining a codeword based on host vehicle information and remote vehicle information, and wherein the codeword indicates whether an expected path for the remote vehicle and an expected path for the host vehicle are convergent, and traversing a portion of the vehicle transportation network in response to the codeword. Determining the codeword may include determining an orientation sector based on a geodesic between the host vehicle and the remote vehicle, determining relative position information for the host vehicle and the remote vehicle based on the orientation sector, determining relative elevation information for the host vehicle and the remote vehicle based on the remote vehicle information and the host vehicle information, and determining relative heading information for the host vehicle and the remote vehicle based on the remote vehicle information and the host vehicle information.
Abstract:
A method and apparatus for use in traversing a vehicle transportation network may include determining a stabilized codeword indicating whether an expected path for the remote vehicle and an expected path for the host vehicle are convergent based on the host vehicle information, the remote vehicle information, and a reference direction, wherein a false negative incorrectly indicating that the expected path for the remote vehicle and the expected path for the host vehicle are divergent on a condition that a difference between a remote vehicle heading angle for the remote vehicle and a reference direction is within a heading approximation offset threshold, is identified as convergent. Traversing a vehicle transportation network may include traversing a portion of the vehicle transportation network in response to the stabilized codeword.
Abstract:
Operating a host vehicle is described as including receiving remote vehicle information indicating a geospatial state and a kinematic state for a remote vehicle, identifying host vehicle information indicating a geospatial state and a kinematic state for the host vehicle, determining a converging time to a converging location within a vehicle transportation network based on the remote vehicle information and the host vehicle information, identifying a first threshold at which a fixed deceleration of the host vehicle to the converging location is achieved using a reaction delay of an operator of the host vehicle, wherein the first threshold is a step-wise function based on the kinematic state of the host vehicle, and modifying operation of the host vehicle responsive to the converging time reaching the first threshold. A method, vehicle, and apparatus are described.
Abstract:
A method for providing information to a driver of a vehicle includes receiving remote vehicle information indicating geospatial state and kinematic state for each of the one or more remote vehicles. The method also includes identifying host vehicle information indicating geospatial state and kinematic state for the host vehicle, identifying a queue length representing a number of vehicles queued ahead of the host vehicle, and identifying at least one of the one or more remote vehicles as a conflicting vehicle. The method also includes determining a time-to-contact based on the remote vehicle information corresponding to the conflicting vehicle and the host vehicle information. The method also includes causing a warning alert to be output if the time-to-contact is less than a warning alert threshold and only if the queue length is zero vehicles.
Abstract:
A method for providing information to a driver of a vehicle includes receiving, at a host vehicle via a wireless electronic communication link, messages that each include remote vehicle information for a respective one of the one or more remote vehicles; identifying host vehicle information for the host vehicle; determining that a potential message occlusion exists based at least in part on the remote vehicle information for the one or more remote vehicles and the host vehicle information; and in response to determining that a potential message occlusion exists, causing a message occlusion alert to be output.

Abstract:
A host vehicle receives a remote vehicle message via a wireless electronic communication link. The remote vehicle message includes remote vehicle information indicating remote vehicle geospatial state information and remote vehicle kinematic state information that includes at least a remote heading angle for a remote vehicle. Host vehicle information is identified that includes host vehicle geospatial state information and host vehicle kinematic state information that includes at least a host heading angle for the host vehicle. Projected vehicle transportation network information representing a portion of the vehicle transportation network is generated based on the remote and host vehicle information, the portion including a curved path having a substantially constant radius. An expected host vehicle route for the host vehicle is determined in response to generating the projected vehicle transportation network information representing the curved path, and the host vehicle traverses the curved path using the expected host vehicle route.
