摘要： A vehicle condition detecting apparatus utilizes a camera mounted on the rear of a vehicle for providing an image including lines indicative of lane boundaries. The image is processed to determine the distances from the vehicle to each line. The distances are compared with predetermined distances by an image processor. A warning device provides a warning based on variations of observed distances with respect to the predetermined distances to warn the driver if the vehicle begins to drift out of a line.
