<P>PROBLEM TO BE SOLVED: To provide a traveling road determination device for vehicle capable of suppressing repeated ON/OFF of a system or generation of an erroneous alarm by a deviation alarm system. <P>SOLUTION: In the traveling road determination device 20 for vehicle for detecting marking lines 5L and 5T on a road surface, a condition T2 for determining the detection of the marking lines based on the frequency or ratio of erroneous detection for the marking lines. The erroneous detection can include the case that no detection of the marking lines is determined. When the frequency or ratio of erroneous detection for the marking lines is high, the condition for determining the detection of the marking lines can be changed more strictly so that the detection of the marking lines is determined only when the marking lines are detected (present) more stably than in the case with a low frequency or ratio of erroneous detection for the marking lines. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
