Driver assistance system
First Claim
1. A method for assisting a driver of a motor vehicle during a lane departure, the method comprising the acts of:
- determining at least a low degree of danger and a high degree of danger for a lane departure via a side area monitoring device of the vehicle, wherein the low degree of danger corresponds to when the side area monitoring device detects an open passing lane and the high degree of danger corresponds to when the side area monitoring detects that the passing lane is not open;
determining a deliberateness of the driver in departing the lane;
upon determining the high degree of danger, triggering a first driver-aid reaction at least in a form of a first counter-steering of the vehicle for steering the vehicle back into the lane, wherein the first counter-steering has a strength that is independent of the determined deliberateness of the lane departure, and wherein the triggering is controlled by a coupling between the side area monitoring device and a lane directional stability monitoring device; and
upon determining the low degree of danger, triggering a second driver-aid reaction as a function of the determined deliberateness of leaving the lane, wherein the second driver-aid reaction comprises a second counter-steering having a strength that is proportional to the determined deliberateness of the lane departure.

Abstract
A driving aid system is provided for assisting a motor vehicle during a change of lane. The system includes a device monitoring the lateral side space and a device monitoring the directional stability. The lateral space monitoring device is designed to determine the degree of risk (for example, two levels: dangerous/not dangerous, or three levels: low/medium/high risk) represented by a change of lane. At the high risk level, a first driving aid reaction occurs, at least in the form of a counter-steering, which is regulated by a link existing between the lateral space monitoring device and the directional stability monitoring device and is expressed by a reorientation towards the specific traffic lane or by maintaining the directional stability. At the low risk level, a second driving-aid reaction is triggered, which is less perceptible and depends on the degree of likelihood of the intention to change lane.
