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 (12) are precalculated by dynamic modeling of the objects, characterized in that a plurality of dynamic models (16) 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 (P1, P2) of the hypotheses for the prediction.

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.

A method for determining a variable associated with an object, the object having a plurality of points suitable for reflecting measuring signals, a probability of reflections occurring at these points is taken into account for evaluating at least one measuring signal.
摘要:
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.

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.
摘要:
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.
摘要:
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.
