1. A method for regulating clearance for a vehicle, in which a relative velocity (vrel) and a relative distance (a) between a vehicle (F1) and a second vehicle driving ahead (F2) is detected, and a control signal (RV) for an adaptive cruise control device of the vehicle (F1) is generated from these quantities, comprising;

  • determining a danger criterion (G) from the relative velocity (vrel) and the relative distance (a);

    weighting the danger criterion (G) with an adaptive factor (AF) corresponding to the individual driving behavior of a driver of the vehicle (F1); and

    generating a control signal (RV) for initiating deceleration of the vehicle (F1) when the danger criterion (GF) weighted with the adaptive factor (AF) adjusted to the vehicle driver falls below a defined threshold value (S).
