WARNING SYSTEM FOR DEVIATION FROM LANE

摘要

PROBLEM TO BE SOLVED: To inexpensively install a lane deviation warning system preventing the deviation of a vehicle from lane and to surely warn deviation from a lane even if the detection precision of vehicle position information for the lane is low. SOLUTION: Magnetism generators 5 outputting magnetism to the vehicle traveling in a lane along the direction of the lane are installed in the lane on the road 3 and magnetism detection means 6L and 6R detecting magnetism from the magnetism generators 5 are provided on the right and left sides of the vehicle 1 in a pair. A warning generation means 17 emitting a lane deviation warning when magnetism from the magnetism generators is detected in the magnetism detection means 6L and 6R is provided for the vehicle 1.
