<p><P>PROBLEM TO BE SOLVED: To provide a lane deviation prevention controller which obtains a steering force at an appropriate support level according to the traveling state of a vehicle. <P>SOLUTION: The line deviation prevention controller includes: a traveling state detection means 140; a line recognition means 110; a target lateral position setting means 120; an own vehicle lateral position recognition means 130; a first steering force operation means 152 for operating a first steering force which is increased according to an increase in the lateral deviation of an own vehicle; a second steering force operation means 153 for operating a second steering force which is increased according to an increase in deviation, and is set to be smaller than the first steering force in an area with smaller deviation whose increasing rate is increased according to the increase in deviation; a target steering force setting means 150 for setting the target steering force by changing ratios of the first steering force and the second steering force according to the traveling state; and a steering force control means 160 for giving the steering mechanism 10 the steering force based on the target steering force. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
