Abstract
A warning system for a vehicle comprises a pair of stereoscopic cameras, image recognizing means for processing images, two warning devices disposed on the left and right side of a driver, the deviation judging means for judging a possibility of deviation from the lane where the vehicle runs or a possibility of collision to obstacles and warning control means for determining the warning device to be operated. When the vehicle has a possibility of deviation from the lane or a possibility of collision to obstacles, either left or right side of the warning device inform the driver of the possibility of deviation or collision, whereby the driver can take a quick action for avoiding hazard. Further, when the vehicle runs on a narrow load, the driver can know an inability of passing through the road by the left and right warning devices operated simultaneously.
