Driver assistance system
First Claim
1. A driver assistance system for a vehicle having a lane-keeping function, comprising:
- a device for detecting lanes on a roadway;
a control unit for intervening in a steering system of the vehicle for lane-keeping;
a position detecting arrangement for detecting a position of the vehicle with respect to edges of a lane;
a cornering detecting arrangement for detecting cornering of the vehicle, wherein the control unit executes a control function as a function of the position of the vehicle on the lane and as a function of the cornering;
a transverse acceleration detecting arrangement for detecting a transverse acceleration of the vehicle; and
an intervention arrangement for performing at least one of the following;
(i) performing, during an approach to an outer curve, an intervention of steering whose intensity increases with the tightness of the curve or the speed of negotiating the curve, and (ii) performing, during an approach to an inner-curve lane marking, an intervention of steering whose intensity decreases with the tightness of the curve or the speed of negotiating the curve.

Abstract
A driver assistance system having a lane-keeping function, having a device for detecting the lanes on a roadway, and a control unit for intervening in the steering system of the vehicle for lane-keeping. Means are provided in the driver assistance system for detecting the position of the vehicle with respect to the lane marking of the lane. Furthermore, means are provided for detecting a travel of the vehicle through a curve. The control unit executes its control function as a function of the position of the vehicle on the lane and as a function of the cornering. The intervention depends on whether the vehicle is located on the inner side of the curve or on the outer side of the curve.
