Abstract: A system for determining the number of remote vehicles following a host vehicle includes a receiver and an electronic controller. The receiver receives information related to a plurality of remote vehicles, including, for each remote vehicle, a vehicle location and a vehicle travel path. The electronic controller determines a location and a travel path of the host vehicle, compares the location of the host vehicle with the vehicle location of each of the remote vehicles, compares the travel path of the host vehicle with the vehicle travel path of each of the remote vehicles, and causes the host vehicle to perform a mitigation operation when the electronic controller determines that a predetermined number of the remote vehicles are disposed behind the host vehicle, and the travel path of the host vehicle and the vehicle travel path of each of the predetermined number of the remote vehicles is the same.

Abstract: A method and apparatus for use in traversing a vehicle transportation network may include receiving a remote vehicle message including remote vehicle information indicating remote vehicle geospatial state information and remote vehicle kinematic state information, identifying host vehicle information including host vehicle geospatial state information and host vehicle kinematic state information, determining convergence information indicating whether a remote vehicle expected path for the remote vehicle and a host vehicle expected path for the host vehicle are convergent based on the host vehicle information and the remote vehicle information, and traversing a portion of the vehicle transportation network in response to the convergence information. Determining the convergence information may include determining an orientation sector based on a geodesic between the host vehicle and the remote vehicle, and determining relative position information for the host vehicle and the remote vehicle based on the orientation sector.

Abstract: Operating a host vehicle is described as including identifying remote vehicle information indicating at least a geospatial state for a remote vehicle and identifying host vehicle information indicating at least a geospatial state for the host vehicle. For a sequence of sampling points, a distance between the remote vehicle and the host vehicle within a transportation network is determined based on the remote vehicle information and the host vehicle information, an angle from a centerline extending from the host vehicle for the distance is calculated, the angle varying as a function of the distance, and a conically-shaped zone is determined using the angle. Responsive to the remote vehicle being located within the conically-shaped zone, the host vehicle is operated based on the remote vehicle being in a lane in which the host vehicle is traveling. The host vehicle is behind the remote vehicle in a direction of travel. 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 condition monitoring system and method employ a storage device that stores information representing a plurality of boundary points of a boundary circumscribing an area of interest in which the boundary points are defined by two prescribed parameters, and a controller that obtains at least one condition point defined by current values of the prescribed parameters, determines a first boundary point of the boundary points that is closest to the condition point, and generates geometric data representing a geometric relationship between the first boundary point, the condition point and a second boundary point of the boundary points. The controller performs further calculations taking into account the geometric data to generate coordinate condition data, and determines whether the condition point lies within the area of interest based on a comparison between coordinates of the condition point and the coordinate condition data.
