Abstract: A vehicle lane change aid system includes a detector that is operative to detect the presence of an other vehicle adjacent the vehicle, an indicator for providing an indication that a lane change maneuver of the vehicle may affect the other vehicle and a control receiving movement information of the vehicle. The control develops a position history of the vehicle at least as a function of the movement information. The control compares the detected presence of the other vehicle with the position history and provides an indication when a lane change maneuver may affect the other vehicle.

Abstract: Preview information is obtained by processing data from image data of a CCD camera, and it is treated as a known disturbance. Then, models for a vehicle and a target road path, typically consisting of DARMA (deterministic auto-regressive moving average) models are prepared so as to give a relationship between a front wheel steering angle command and a lateral deviation of the vehicle. An extended generalized predictive control theory is applied to these models so as to compensate for tracking errors that may arise as a result of the known disturbance. Thus, a favorable tracking capability can be achieved with a relatively simple structure, by executing a prediction control which requires only such variable that can be measured both easily and accurately.

Abstract: An apparatus and method for correctly determining the position of a vehicle in a traffic lane by obtaining correct information about the position of the traffic lane without being affected by variations in the road surface, weather, time of day, or such imaging conditions as fixed or moving lighting, are provided. An edge signal of a high spatial frequency component and a luminance signal of a low spatial frequency component of a digital image signal representing the view of the local area to the front of a vehicle are extracted. A road contour signal is then extracted from the edge signal, and a road region signal is extracted from the luminance signal. The position of the lane Sre is then detected with high precision by evaluating the lane contour Sre based on the road region signal Srr and lane contour data Sre.

Abstract: A road lane recognizing apparatus can accurately recognize a road lane position from an image shown by an actual road surface image signal obtained by picturing a road surface in front of a vehicle by means of picturing means such as a television camera or the like mounted on the vehicle. Whether the vehicle exists on a straight part of road or not is discriminated in accordance with a vehicle-self position detected by vehicle detecting means. When the vehicle exists on the straight part, an attitude angle showing the direction of the vehicle for the road direction at the vehicle-self position is detected. When the attitude angle is detected, a predetermined ideal road surface image is inclined by only the attitude angle, thereby obtaining the corrected road surface image. The actual road surface image signal from the picturing means is compared with a signal of the corrected road surface image. An image difference is used as an offset amount. The actual road surface image is corrected by only the offset amount. The road lane position is recognized on the basis of the image shown by the corrected actual road surface image signal.

Abstract: A vehicle tracking system for determining the lateral position of a moving vehicle relative to an optically distinct line extending along the roadway on which the vehicle travels. A camera periodically scans the roadway including the optically distinct line thereon. Signals representing successive scans are stored then correlated to determine the lateral movement of the vehicle between scans.
