Abstract
A drive control method controls a drive control amount of a subject vehicle so that the subject vehicle may take a prescribed position with respect to lane markings of a lane in which the subject vehicle is running and reduces a drive control amount adopted when a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking smaller than a drive control amount adopted when lateral positions of both the lane markings move in the same direction.
Claims4
A drive control method comprising recognizing lane markings of a lane in which a subject vehicle is running and controlling a drive control amount of the subject vehicle so that the subject vehicle may take a prescribed position with respect to the lane markings of the lane, characterized in that:
- a judging unit configured to judge if a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking is equipped;
- and
- when it is judged that a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking, the drive control amount is reduced smaller than when lateral positions of both the lane markings move in the same direction.
A drive control apparatus comprising:
- a lane marking recognition circuit to recognize lane markings of a lane in which a subject vehicle is running;
- a judging unit to decide if a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking;
- and
- a vehicle control circuit to control a drive control amount of the subject vehicle so that the subject vehicle may take a prescribed position with respect to the lane markings recognized by the lane marking recognition circuit, characterized in that:
- when it is judged that a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking, the vehicle control circuit reduces the drive control amount smaller than when lateral positions of both the lane markings move in the same direction.
