    摘要： It is an object to provide a lane departure warning device capable of generating almost no false warning if a driver performs an avoiding operation of a lane departure. The lane departure warning device estimates the steering amount of the own vehicle toward the center of the lane or the amount correlating with this steering amount based on the parameter representing the vehicle behavior such as the steering angle, the yaw rate and the lateral G, thereby detecting the state of the vehicle steering toward the center of the lane when a driver is performing an avoiding operation to avoid the lane departure (quick steering), and determining whether or not the possibility of the vehicle's departure from the lane is high without using the time TLC and its threshold value Ts, but only based on the determination whether or not the distance D1 or D2 from the outer edge of the front wheel to the marking line is less than the threshold value Ds if the driver performs the avoiding operation to avoid the lane departure (quick steering).

    摘要： There is provided a lane departure warning apparatus capable of preventing false warnings and absence of a warning regarding lane departure which is attributed to special road geometries such as junctions and tollgates. The lane departure warning apparatus for outputting a warning signal upon determining departure of a vehicle from a lane, performing the steps of: when one dividing line in a vehicle width direction of the vehicle is non-detected, estimating a position of the one dividing line based on a position of the other dividing line as a first estimation dividing line; estimating a position of the non-detected one dividing line based on a position of the one dividing line prior to non-detection as a second estimation dividing line; and comparing the first estimation dividing line with the second estimation dividing line to determine lane departure.
