1. A method for longitudinally controlling a vehicle having a navigation system which stores roadway information, the method comprising the acts of:
- obtaining the roadway information from the navigation system;
determining a probability with which the vehicle will drive onto a highway entrance based on the roadway information; and
specifying a longitudinal acceleration for the vehicle that is greater than the longitudinal acceleration during regular operation when the probability is greater than a specified threshold value.

Abstract
In a method for the longitudinal control of a vehicle, where information from a navigation system is recorded and where a target value of at least one parameter for longitudinal control is determined in dependence on the information from the navigation system, the information from the navigation system is used to determine the probability with which the vehicle will drive onto a highway entrance. When the probability is higher than a specified threshold the control unit uses a longitudinal acceleration that is increased compared to regular operation.
