1. A lane-keep control system for a host vehicle, comprising:
- a control unit configured, to detect a traveling condition of the host vehicle, to determine whether there is a tendency of a lane deviation indicative that the host vehicle is deviating from a traveling lane, according to the traveling condition, to execute a lane-keep control for controlling the host vehicle toward a deviation-preventing direction of preventing the lane deviation according to the traveling condition when there is the tendency of the lane deviation, to limit the lane-keep control when the lane-keep control is executed according to the determination as to the tendency of the lane deviation and when the determination as to the tendency of the lane deviation is made according to the traveling condition under a condition that the host vehicle is traveling a lane-deviation area deviated from the traveling lane.

Abstract
A lane-keep control system for a host vehicle is arranged to execute a lane-keep control of controlling the host vehicle toward a deviation-preventing direction of preventing the lane deviation according to a vehicle traveling condition when there is a tendency of the lane deviation and to limit the lane-keep control when a determination as to the tendency of the lane deviation is made under a condition that the host vehicle is traveling a lane-deviation area deviated from a traveling lane.

17. A method of executing a lane-keep control for controlling a host vehicle toward a deviation-preventing direction of preventing a lane deviation, the method comprising:
-
detecting a traveling condition of the host vehicle;
determining whether there is a tendency of the lane deviation that the host vehicle is deviating from a traveling lane according to the traveling condition;
executing the lane-keep control according to the traveling condition when there is the tendency of the lane deviation; and
limiting the lane-keep control when the lane-keep control is executed according to the determination as to the tendency of the lane deviation and when the determination as to the tendency of the lane deviation is made according to the traveling condition under a condition that the host vehicle is traveling a lane-deviation area deviated from the traveling lane.

18. A lane-keep control system for a host vehicle, comprising:
-
traveling-condition detecting means for detecting a traveling condition of the host vehicle;
lane-deviation determining means for determining whether there is a tendency of a lane deviation that the host vehicle is deviating from a traveling lane according to the traveling condition;
lane-keep control means for executing a lane-keep control of controlling the host vehicle toward a deviation-preventing direction of preventing the lane deviation according to the traveling condition when there is the tendency of the lane deviation; and
control limiting means for limiting the lane-keep control when the lane-keep control is executed according to the determination as to the tendency of the lane deviation and when the determination as to the tendency of the lane deviation is made according to the traveling condition under a condition that the host vehicle is traveling a lane-deviation area deviated from the traveling lane.
