Abstract
When a vehicle is moving out of a lane of a road, an image processing computer unit judges the hazardous condition. Then, a power steering control computer unit calculates a correction reaction force based on the steering angular velocity and increases a steering reaction force so as to generate a large steering effort. This lane moving-out prevention system is constituted such that only when the steering angular velocity is large, i.e., when a driver turns a steering wheel sharply, the steering reaction force is increased, thereby no additional reaction force is produced when the driver makes a normal turn.
