Abstract

The specification discloses a method for spacing control for a motor vehicle, in which the current driving speed of the motor vehicle and the current spacing of the vehicle from an object in front of the vehicle are determined by sensor devices, and a spacing-dependent required acceleration is produced from the detected variables. For this purpose, a speed-dependent required acceleration is determined from a desired speed which is manually predetermined by the vehicle driver, and is compared with the spacing-dependent required acceleration. A manipulated variable for the driving engine and/or the braking system of the motor vehicle is then generated as a function of the required acceleration.
