Vehicle traveling control system and vehicle control device

摘要

A vehicle traveling control system and a vehicle control device whereby markers are detected with reliability and information about a local vehicle is transmitted to a succeeding vehicle. Information collecting unit of a preceding vehicle acquires information about the traveling state of the local vehicle associated therewith and supplies the acquired information to modulating unit. The modulating unit modulates the information supplied thereto and supplies the modulated information to blinking unit. The blinking unit causes the markers to blink in accordance with the information supplied thereto. Imaging unit of the succeeding vehicle acquires images of the markers and supplies the acquired images to specifying unit. The specifying unit specifies the marker images from within the image data output from the imaging unit. Validity determining unit determines validity of the specified marker images. Using the marker images, distance measuring unit measures a distance to the preceding vehicle. Demodulating unit demodulates information superimposed on the markers to reproduce the original information. In accordance with the information obtained from the distance measuring unit and the demodulating unit, control unit controls the traveling state of the local vehicle associated therewith.
