A method and a driver assistance system for estimating a distance 41 of a vehicle 11 to an object 12, such as a preceding vehicle, in which the distance is estimated by means of elevations of a progression of a surface or road 17 on which the vehicle is moving. The system includes a camera 13 arranged to capture images of the road in front of the vehicle and an image processor 16 which locates an object in the vicinity of the vehicle. A control device 15 estimates the distance between the vehicle and the object, taking into account the gradient of the road between the vehicle and the object. The gradient may be determined from a digital map stored on a digital storage medium such as a CD-ROM device 24. |
