Abstract
The lane mark recognition device is equipped with a lane mark detecting unit which executes a lane mark detection process in each predetermined control cycle, and adds a detection presence/absence data to a ring buffer, a detection presence/absence data addition inhibiting unit which inhibits addition of the detection presence/absence data to the ring buffer when the vehicle is traveling in the intersection, and a lane mark position recognizing unit which recognizes a relative position of the vehicle and the lane mark, when the lane mark is detected in the situation where a lane mark detection rate calculated from the data of the ring buffer is higher than a reliability threshold value.
