Abstract

A driving assistance method is provided for a vehicle in which the speed of the vehicle is controlled by means of a longitudinal guidance control system and the lateral guidance of the vehicle is controlled by means of a lateral guidance control system, and wherein lateral guidance control, which includes yaw-rate control and/or lateral acceleration limitation, has priority over speed control. To reduce the danger of an unstable handling condition of the vehicle, and to assist the vehicle operator in driving the vehicle, the longitudinal guidance control system is activated during lateral guidance control and, after lateral guidance control has ended, the longitudinal guidance control system is turned off or is shifted to an operating condition that accelerates the vehicle with longitudinal acceleration below a predetermined index longitudinal acceleration.
