ABSTRACT:
There is provided a lane deviation prevention apparatus which can make a lane deviation prediction judgment more accurately. The lane deviation prevention apparatus includes driving lane shape recognition device to detect a lane mark on a road included in a front image within a lane mark detection distance range and to recognize a shape of a driving lane boundary, and a deviation prediction judgment device that judges, based on the shape of the driving lane boundary, whether the vehicle deviates from a driving lane after a previously set deviation prediction time and outputs a deviation prevention output in a case where it is judged that the vehicle deviates, and the driving lane shape recognition device that dynamically sets the position of the lane mark detection distance range in accordance with a vehicle speed of the vehicle and the deviation prediction time.
