Abstract
A particular area extending in a widthwise direction of a vehicle is established in a lower part of a picture image taken by CCD cameras and the area is divided into six small areas. It is judged that a stop marker exists when an average brightness of respective three successive small areas of the six small areas rises from a low level to a high level and then descends from the high level. As a result of recognition of a stop marker, in case where a stop marker exists and there is a solid object immediately ahead of the stop marker, a drive assist system gives a warning to a vehicle operator or a congestion follow-up mode is turned off. Further, in case where a stop marker exists and there is a solid object immediately ahead of the stop marker, while the vehicle is in a standstill, the drive assist system prohibits the vehicle operator from starting the vehicle.
