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.

Abstract: A vehicle contact warning method and system are provided in a host vehicle. A communication device of the host vehicle receives a remote vehicle message including information pertaining to a remote vehicle including a remote vehicle location and a remote vehicle trajectory. A controller of the host vehicle prepares a host vehicle location and a host vehicle trajectory. The controller determines a possibility of contact between the host vehicle and the remote vehicle at a contact location at a contact time based on a host vehicle travel time from the host vehicle location to the contact location based on the host vehicle information and a remote vehicle travel time from the remote vehicle location to the contact location based on the remote vehicle information. The controller automatically operates an external warning device to the host vehicle, the remote vehicle, or both, upon determining the possibility of contact exists between the host vehicle and the remote vehicle.

Abstract: An on-board vehicle control 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 a warning condition exists by determining 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.

Abstract: An on-board vehicle control system and method employ a storage device that stores information representing a plurality of boundary points of a boundary that circumscribes an area of interest, and a controller that obtains a vehicle location of a vehicle of interest, determines a first boundary point closest to the vehicle location, and generates data representing a geometric relationship between the first boundary point, the vehicle location and a second boundary point. The controller calculates reference point data representing a reference point based on the data representing the geometric relationship, determines coordinate condition data based on an angle between a predetermined direction and a reference line connecting between the first boundary point and the reference point, and determines whether the vehicle location lies within the area of interest based on a comparison between geographic coordinates of the vehicle location and the coordinate condition data.
