LANE DEVIATION ALARM DEVICE, METHOD OF CONTROLLING LANE DEVIATION ALARM DEVICE, AND PROGRAM FOR THE METHOD

摘要

A lane deviation alarm device which, when a vehicle deviates from a driving lane, allows the driver of the vehicle to instantaneously know the direction of the deviation. The lane deviation alarm device (10) has a lane recognizing section (14) for recognizing the driving lane on which a vehicle (1) is driving, a lane deviation determining section (15) for determining deviation of the vehicle (1) from the driving lane recognized by the lane recognizing section (14), and a notification controlling section (16) which, when the lane deviation determining section (15) determines that the vehicle (1) has deviated from the driving lane, issues warning to the driver. The warning is issued by a speaker, which is either of at least two speakers (33a, 33b) arranged at the left and right, as viewed from the seated driver, inside the vehicle (1) and which is located on that side of the vehicle (1) which has deviated the driving lane, such that the speaker emits a scratch sound or a collision sound having a greater volume than a sound emitted from the speaker on the side opposite the side which has deviated the driving lane.
