Abstract: A CCD camera or equivalent sensor is mounted on a vehicle and used to detect lane markings (usually the white or yellow painted lines) on a roadway. An electric motor coupled to a steering system is used to provide a torque input to the steering, which may either assist or oppose the steering torque from a driver. A steering controller is designed to assist the driver to maintain the vehicle lane position by holding the vehicle at a target point using a biasing torque. The controller resumes application of the biasing torque upon expiration of a predetermined period of delay time since a change from the absence of detection of lane marking to the presence of detection of lane marking after the presence of detection of lane marking that continues for a period of time less than a predetermined period of time has occurred a predetermined number of times within a predetermined period of monitoring time or the absence of detection of lane marking continues for a predetermined period of time.

Abstract: A system for assisting a lane-keep traveling of a vehicle is comprised of a camera for detecting a view ahead of the vehicle, a vehicle behavior detector including a vehicle speed sensor and a yaw rate sensor, and a controller. The controller is arranged to estimate a road shape on the basis of lane markers detected by the camera, to detect a target yaw rate necessary to return the vehicle at a center of the lane markers, and to determine that there is a possibility that the vehicle deviates from the lane when a difference between the target yaw rate and an actual yaw rate detected by the yaw rate sensor becomes greater than a threshold.

Abstract: An apparatus for vehicle lane following in which a look ahead sensor including a CCD camera and an image processor detects a lane marking on the surface of a roadway. The image processor estimates a lateral displacement of a point at a preview distance in front of a vehicle from a target line. The target line is a line between lane markings defining a lane. An electric motor coupled to the steering mechanism is used to provide a bias (a torque input) to the steering, which may either assist or oppose to the steering torque from the driver. A steering controller is designed to assist the driver to maintain the vehicle's lane position by holding the vehicle at the target line using a biasing torque if the lane following is selected by the driver. In order to reflect the driver preference in the lane following, the controller collects a sufficient number of measures of the vehicle lateral displacement when the lane following is not selected.
