摘要:
The subject matter of the invention is a driver assistance system (100) for keeping the vehicle (18) in its lane (20). A controller which regulates the steering adjuster comprises a transmission member with a characteristic curve. Depending on the deviation (F) between the calculated curvature and the curvature predefined by the driver, an advantageous, hysteric warning is emitted.

The invention relates to a driver assistance system 1 for a vehicle 100 having a plurality of safety functions, such as particularly an LDW function and an LKS function, system-dependent limit values being provided for the safety functions, the safety functions being activated if they are not maintained and being deactivated if they are exceeded. The limit values are designed to be variable according to the invention.
摘要:
The invention relates to a device for keeping a vehicle (18) in its traffic lane (20). Said device comprises a steering actuator (3) which exerts a steering torque (M A ) on the steering system (1) of the vehicle (18), a traffic lane detection system (17) determining the relative position of the vehicle (18) in relation to the traffic lane (20) it is in and the traffic lane curvature, and a reference model (11) which calculates a reference steering angle (delta ref ) depending on the position of the vehicle (18). The vehicle (18) can be automatically guided in its traffic lane if a control circuit (21) for controlling the steering angle is provided which comprises a transmission element (13) and the steering actuator (3). The transmission element (13) is characterized by a regulative behavior that efficiently regulates a deviation of the steering angle (delta).

The invention relates to a servo steering system for motor vehicles, comprising a steering adjuster (11) by means of which a supporting moment (Mu) can be applied to the steering mechanism (12) of the vehicle (1), a lane recognition system (13) for recognizing information regarding the course of the lane, a reference model (3) that calculates a reference steering angle (δRef) in accordance with the data received from the lane recognition system (13), and a transmitting member (16) that determines the supporting moment (Mu) transmitted to the steering mechanism (12) by the steering adjuster (11) in accordance with the driving condition. The transmitting member (16) is designed such that the neutral position of the steering characteristics (17) is identical to the reference steering angle (δRef) and moves along with the reference steering angle (δRef) in accordance with the course (15) of the lane.

摘要:
A method for situation analysis for a driver assistance system on board a motor vehicle comprises steps of provision of a representation of surroundings of the motor vehicle, wherein the representation comprises an arrangement of cells that are reversibly explicitly associated with predetermined sections of the surroundings, of scanning of surroundings of the motor vehicle by means of at least one sensor in order to sense an obstacle, and of marking cells on the basis of the scan such that a cell that is associated with an obstacle-free section of the surroundings carries a first marker and a cell that is associated with a section of the surroundings in which an obstacle has been sensed carries a second marker. A morphological filter is then applied to the representation in order to provide cells that cannot be reached by the motor vehicle with the second marker.
摘要:
Described is a method for operating a driver assistance system (100) for a vehicle (300) driving on a roadway (300), comprising the following steps: - detecting a narrow roadway section (500) lying ahead of the vehicle (300) as well as at least one oncoming vehicle (400) approaching the vehicle (300); - determining the distance (d 2 ) to and the width (b 3 ) of the narrow roadway section (500) as well as the distance (d 1 ) to and the width (b 2 ) and current cruising speed (v 2 ) of the oncoming vehicle (400); - predicting the expected driving paths (310, 410) of the vehicle (300) and the oncoming vehicle (400) and determining a point (250) where the two vehicles (300, 400) are expected to pass each other; - assessing the predicted traffic situation; and - activating a safety device (150) if the point (250) where the two vehicles (300, 400) are expected to pass each other lies in the area of the narrow roadway section (500), the point in time when the safety device (150) is activated being determined according to the current traffic situation.
