A method for operating a driver-assistance system for a vehicle traveling on a road is described, which includes the steps:

Driver-assistance system and method for operating the driver-assistance system

A method for determining an object angle, especially for a driver assistance system in a motor vehicle, includes the steps of determining directional angles of the object with respect to two sensors, determining the object angle based on the directional angles, determining a cross-misalignment angle as the difference of the determined directional angles, determining a validity signal indicating the validity of the object angle based on the cross-misalignment angle and compensating for the influence of a relative misalignment of the sensors on the determined object angle based on the cross-misalignment angle.

Object sensor

A method and device for identifying and classifying objects, electromagnetic radiation being emitted by a sensor, the radiation components reflected on objects being received by the sensor, the received signals being analyzed by comparison with stored characteristic values and the class of the reflecting object being deduced on the basis of the analysis. To this end, an analyzer is provided for analyzing the received signals, a memory is provided for storing characteristic patterns, its stored patterns being compared with the analyzed signals and thus the class of the reflecting objects being deducible on the basis of the comparison.

A method for predicting object movements in a driver assistance system of a motor vehicle, in which the movements of objects located periodically by a locating device () are precalculated by dynamic modeling of the objects, characterized in that a plurality of dynamic models () are held in readiness which are based on different hypotheses about the object, and that the models are selected and/or weighted as a function of the situation in accordance with the correctness probability (P, P) of the hypotheses for the prediction.

Method for determining a dynamic variable representative for a lateral movement of a located object in a driver assistance system for motor vehicles, which has two angle-resolving distance sensors situated laterally offset to one another for locating the object, using which a radial component of the relative velocity of the object along the particular line of sight is also measurable, wherein the dynamic variable is calculated on the basis of the radial components of the relative velocity measured by the two distance sensors.

In an object verification method for use in radar systems for motor vehicles, the distances and relative velocities of located objects are determined on the basis of received radar echoes. The signature of multiple reflections is searched for in the received radar echoes to verify real objects.

Object verification method for use in radar systems for motor vehicles

A method and device for object detection in the case of a vehicle equipped with an object-detection system, the object-detection system emitting electromagnetic radiation and receiving radiation reflected off objects within the detection range, and the radiation reflected off a detected object, which was additionally reflected off an object extending along the roadway, is analyzed. The analysis consists of a plausibilization in which the directly measured object reflections are verified using the indirect object reflections, or in that the analysis consists of utilizing the indirect object reflections for the further object detection if reflections from a previously detected object are no longer measurable.

Method and device for object detection in the case of a vehicle

A method and device are provided for measuring distance and relative speed of a plurality of objects with the aid of an FMCW radar, transmitted signals being reflected by objects, and the reflected signals being received and mixed with the transmitted signals. A combination of distance and relative speed values is assigned to the mixer output frequencies of each frequency ramp for each object, and the distance and relative speed of a possible object are determined from points of intersection of a plurality of distance and relative speed combinations. The apparent (unreal) objects are eliminated by modifying the frequency slope of at least one frequency ramp according to the random principle in a subsequent measurement cycle.

In a method for estimating the width of radar objects in a position finding system for motor vehicles, which has at least two angle-resolving radar sensors, the reflection points positioned by several of the radar sensors, which are to be assigned to the same object on the basis of their distance data and relative velocity data, are combined into a group, lateral positions of the reflection points from this group are calculated, the difference of the lateral positions is calculated for various pairs of these refection points, and the maximum of these differences is sought out to determine an estimated value for a minimum width of the object.

A method and a system for switching between a first operating mode and a second operating mode of a target control device connected to a data bus are provided. After activation of the target control device, a test device generates a predefined signal to be transmitted on the data bus, the predefined signal having a predefined frequency and a predefined pulse-duty factor. The target control device is switched from the first operating mode to the second operating mode in response to detecting the predefined signal transmitted on the data bus.

Method and device for changing over a first mode of a control device to a second mode, via a data bus

A radar sensor and a corresponding method for distance and cruise control of a vehicle are described; using this sensor and method, objects in front of the vehicle in the direction of travel are detected and at least the variables: distance, relative velocity, and azimuth angle of the detected objects are ascertained with regard to the vehicle, the change over time of the reflection point of the radar beam on the object and classification of the detected object being determined as a function of the change over time of the reflection point.
