On-board vehicle control system and method for determining whether a value is within an area of interest for extraneous warning suppression
First Claim
1. A condition monitoring method comprising:
- storing information representing a plurality of boundary points of a boundary that circumscribes an area of interest in which the boundary points are defined by at least two prescribed parameters;
obtaining via an on-board controller at least one condition point defined by current values of the prescribed parameters;
determining via the on-board controller a first boundary point from the plurality of boundary points that is closest to the condition point;
generating via the on-board controller geometric data representing a geometric relationship between the first boundary point, the condition point and a second boundary point of the boundary points, the geometric relationship including a first straight line connecting the first boundary point and the condition point, a second straight line connecting the second boundary point and the condition point, and a third straight line connecting the first boundary point and the second boundary point;
calculating via the on-board controller reference point data representing a reference point based on the geometric data;
determining via the on-board controller coordinate condition data based on an angle between a predetermined direction and a reference line connecting the first boundary point and the reference point; and
determining via the on-board controller 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 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.
