20090271071 | METHOD FOR CONTROLLING A DRIVER ASSISTANCE SYSTEM - A method for controlling a driver assistance system having an LKS function of a vehicle is described. In the region of lane widening, a hypothetical lane which connects a starting lane to a destination lane is generated by the driver assistance system. In the region of the lane widening, the vehicle is guided along the hypothetical lane. | 10-29-2009 |
20100004821 | KS Lateral Guidance System Having a Modified Control Characteristics When Cornering - A device for keeping a vehicle in its lane, including a reference model, which obtains geometric data regarding the position of the vehicle in the lane as well as data relating to the course of the lane from a lane detection system, and from these calculates a setpoint variable for controlling the vehicle position. In order to allow for corners to be cut, the guiding behavior of the control system is modified in such a way when cornering that, in the event of a deviation of the path of motion of the vehicle from the setpoint path of motion in the direction of the inside of the curve, no or only low steering forces are applied to the steering system. | 01-07-2010 |
20100138101 | DRIVER ASSISTANCE DEVICE AND METHOD FOR CONTROLLING IT - A driver assistance device for a vehicle having a plurality of safety functions, such as in particular an LDW function and an LKS function, in which system-related boundary values are provided for the safety functions such that when they are undershot the safety function is activated and when they are exceeded the safety function is deactivated. The boundary values are developed to be variable. | 06-03-2010 |
20100185363 | METHOD AND DEVICE FOR THE CONTROL OF A DRIVER ASSISTANCE SYSTEM - The invention relates to a method and a device for the control of a driver assistance system ( | 07-22-2010 |
20100228438 | METHOD FOR ADJUSTING A STEERING SYSTEM IN A VEHICLE - In a method for adjusting a steering system in a vehicle, a setpoint trajectory is produced to which a tolerance corridor is assigned, a basic steering torque for guiding the vehicle within the tolerance corridor being generated. In the event that the vehicle leaves the tolerance corridor, a steering guidance torque which acts upon the vehicle in the direction of the tolerance corridor is superimposed on the basic steering torque. | 09-09-2010 |
20100286866 | METHOD FOR CONTROLLING A DRIVER ASSISTANCE SYSTEM - In a method for controlling a driver assistance system, the activation of LKS (lane keeping support) function may result in lateral pendulum motions of the vehicle. Zones having specified conditions are defined in a region of the traffic lane in front of the vehicle. Within the zones, a check is performed to determine whether the respective driving state of the vehicle matches the specified conditions. In the event of a match, the existence of a pendulum motion of the vehicle is assumed. | 11-11-2010 |
20110001617 | METHOD FOR WARNING THE DRIVER OF A MOTOR VEHICLE OF INCREASED RISK OF AN ACCIDENT - In a method for warning the driver of a motor vehicle, the yaw rate is altered in the event of an increased risk of an accident, and the change in the yaw rate serves to warn the driver of the increased risk state. | 01-06-2011 |
20120206708 | METHOD AND CONTROL UNIT FOR ROBUSTLY DETECTING A LANE CHANGE OF A VEHICLE - A method for detecting a lane change of a vehicle or for providing a curvature of a target line for lane guidance of a vehicle is described, the method including a step of receiving a first piece of traffic lane information which represents an optically detected first traffic lane boundary adjacent to or in front of a left-hand vehicle side and/or receiving a second piece of traffic lane information which represents an optically detected second lane boundary adjacent to or in front of a right-hand vehicle side. The method further includes a step of detecting a lane change if the first and/or the second piece(s) of traffic lane information represent(s) a traffic lane boundary which is less than a predetermined lateral distance to a vehicle side, or ascertaining a curvature of a desired target line for lane guidance of a vehicle from the first piece of traffic lane information weighted using a first weighting factor and the second piece of traffic lane information weighted using a second weighting factor, on the basis of a correlation observation. | 08-16-2012 |
20130096767 | METHOD AND DEVICE FOR LANE KEEPING ASSISTANCE REGULATION - In a lane keeping assistance method for a vehicle which is traveling in a lane, it is checked whether an activation criterion for an automatic driving dynamics intervention is satisfied, and in response to the satisfaction of the activation criterion, control signals are output for the driving dynamics intervention. A remaining travel time to crossing or reaching a lateral lane line is ascertained and compared to a threshold value as the activation criterion. During the automatic driving dynamics intervention, a deactivation criterion for ending the automatic driving dynamics intervention is checked, the deactivation criterion including a comparison of a vehicle alignment to a lane direction. | 04-18-2013 |
20130158960 | METHOD AND CONTROL UNIT FOR VALIDATING AN ILLUMINATION-RANGE TEST VALUE OF A LIGHT CONE OF A VEHICLE HEADLIGHT - A method for validating an illumination-range test value of a light cone of at least one headlight of a vehicle. The method includes reading in a reflection intensity of a point on at least one road marking illuminated by the light cone; generating a reflection intensity model for the road marking, based on the obtained reflection intensity and a particular distance of the point from the vehicle, the reflection intensity model being designed to assign different reflection intensities to different positions on the road marking in front of the vehicle; determining an illumination-range plausibility value, at which, according to the reflection intensity model, a reflection intensity is reached, which corresponds to a reflection-intensity threshold value; and comparing the illumination-range plausibility value to the illumination-range test value, to validate the illumination-range test value, if the illumination-range plausibility value is inside a tolerance range around the illumination-range test value. | 06-20-2013 |
