Corner Positions Overview

In accordance with the NHTSA Lane Departure Warning System NCAP Confirmation Test December 2008, “Lane departure is said to occur when any part of the two dimensional polygon used to represent the test vehicle breaches the in board lane line edge. In the Case of tests performed in this procedure, the outside front corner of the polygon will cross the line edge first”.

“The corners of the polygon are defined by the lateral and longitudinal locations where the plane of the outside edge of each tire makes contact with the road. This plane is defined by running a perpendicular line from the outer most edge of the tire to the ground.”

Before corner positions are set, please connect the VBOX equipment within the vehicle as shown in Lane Departure Test Schematic.
