Lane keep control apparatus and method for automotive vehicle
First Claim
1. A lane keep control apparatus for an automotive vehicle, comprising:
- a traffic lane detecting section that detects a traffic lane on which the vehicle is running;
a traveling state detecting section that detects a traveling state of the vehicle;
a deviation determining section that determines whether the vehicle has a tendency to be deviated from the traffic lane according to the traffic lane detected by the traffic lane detecting section and the traveling state of the vehicle detected by the traveling state detecting section; and
a vehicular behavior controlling section that controls a behavior of the vehicle in such a manner that a yaw moment of the vehicle is developed in a direction to avoid a deviation of the vehicle from the traffic lane in accordance with the traveling state detected by the traveling state detecting section when the deviation determining section determines that the vehicle has a tendency of the deviation of the vehicle from the traffic lane, the traffic lane detecting section including a lane marker detecting section that detects lane markers, each lane marker representing one side of the traffic lane, and the vehicular behavior controlling section controlling the behavior of the vehicle on the basis of the detected lane marker at one side of the traffic lane when the lane marker detecting section transfers a detection state from a state in which both of the lane markers at both sides of the traffic lane are detected to a state in which the lane marker only at one side of the traffic lane is detected.

Abstract
In lane keep control apparatus and method for an automotive vehicle, a behavior of the vehicle is controlled in such a manner that a yaw moment is developed in a direction to avoid a deviation of the vehicle from the traffic lane in accordance with the traveling state of the vehicle when determining that the vehicle has a tendency of the deviation of the vehicle from the traffic lane and lane markers are detected, each lane marker representing one side of the traffic lane, and the behavior of the vehicle is controlled on the basis of the detected lane marker at one side of the traffic lane when a detection state of the lane markers is transferred from a state in which both of the lane markers at both sides of the traffic lane are detected to a state in which the lane marker only at one side of the traffic lane is detected.
