Driver Assistance System
First Claim
1. A driver assistance system for assisting a driver of a motor vehicle during a change of lane, the driver assistance system comprising:
- a side area monitoring device that determines a degree of danger for a lane change;
a lane directional stability monitoring device operatively coupled with the side area monitoring device; and
wherein in an event of a high degree of danger determined by the side area monitoring device, independently of a degree of probability concerning a deliberateness of leaving the lane, a first driver-aid reaction is triggered at least in a form of a counter-steering, which is controlled via the coupling between the side area monitoring device and the lane directional stability monitoring device in order to steer the vehicle back into the defined traffic lane or to maintain the directional stability within the defined traffic lane.

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.

14. A method for assisting a driver of a motor vehicle during a lane departure, the method comprising the acts of:
-
determining a degree of danger for a lane departure via a side area monitoring device of the vehicle;
determining a probability degree with respect to a deliberateness of the driver in departing the lane;
upon determining a high degree of danger, triggering a first driver-aid reaction at least in a form of a counter-steering of the vehicle for steering the vehicle back into the lane, wherein the triggering is controlled by a coupling between the side area monitoring device and a lane directional stability monitoring device; and
upon determining a low degree of danger, triggering a second driver-aid reaction as a function of the probability degree of the deliberateness of leaving the lane. - View Dependent Claims (15, 16, 17, 18, 19)
