Device for controlling the speed of a vehicle

The arrangement has an object detection system for detecting vehicles in front of the vehicle (1) and whose measurement value are used to regulate the vehicle speed and/or inter-vehicle distance. The object detection sensing system (3) has a first detection region (4) with a long range with increasing detection width with increasing distance and a maximum width corresponding to the lane (2) in which the vehicle is traveling and further detection regions (5-8) with shorter covering regions to the left and right of the first detection region.
