Abstract
A lane boundary recognition system for a self-navigating vehicle which enables the vehicle to self-navigate on an expressway or other such roadway having lane boundaries while simultaneously identifying and discriminating the continuity of the lane boundaries. Vehicle position to the lane boundaries are determined at times T0 and T1. A vehicle locus occurred in a period between the times is estimated and the position at the time T0 is corrected. A difference between said corrected position and said position at the time T1 is calculated and is adding to lane boundary numbers and by comparing them with each other, it is determining if the lane boundaries recognized at the times T0 and T1 are continuous. If determined to be continuous, the same number is assigned and is stored in a common memory.
