Abstract
The present invention relates to a method for regulating clearance for a vehicle, in which a relative velocity (vrel) and a relative distance (a) between the vehicle and a second vehicle driving ahead are detected, and a control signal for an adaptive cruise control device is generated from these quantities. The control signal being derived from a danger criterion (G) is determined from the relative velocity (vrel) and the relative distance (a), this danger criterion which is weighted with an adaptive factor (AF) representing the individual driving behavior of a vehicle driver, and a control signal initiating a deceleration of the vehicle is generated when the danger criterion (GF), weighted with the adaptive factor and adapted to the vehicle driver, falls below a defined threshold value (S).
