Claim:
A lane keep control apparatus for an automotive vehicle, comprising: 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 of a deviation from the traveling traffic lane according to the traveling state detected by the traveling state detecting section; a deviation preventive controlling section that executes a deviation avoidance control for the vehicle in a direction to avoid the deviation according to the traveling state detected by the traveling state detecting section; a steering angle detecting section that detects steering angles before and after a start of the deviation avoidance control executed by the deviation preventive controlling section; and a deviation avoidance controlled variable correcting section that corrects a controlled variable of the deviation avoidance control executed by the deviation preventive controlling section on the basis of a deviation between a steering angle before the start of deviation avoidance control and that after the start of deviation avoidance control detected by the steering angle detecting section when the deviation determining section determines that the vehicle has the tendency of the deviation.
