Method and device for the position determination of objects in road traffic, based on communication signals, and use of the device

Abstract

The invention relates to a method for the communication signal-based position determination of objects in road traffic, in which at least one data-transporting communication signal is wirelessly transmitted from at least one sender (217, 218, 219, 220, 221, 34) and is reflected at least proportionally as a reflection signal on at least one object (211, 212, 213, 214, 215, 216, 35), wherein the at least one communication signal and the reflection signal are received by a receiver (222, 33), and wherein the receiver (222, 33) knows its own position and a location of the at least one sender (217, 218, 219, 220, 221, 34). The method is characterized in that a propagation time difference of the communication signal and the reflection signal is determined by the receiver (222, 33). The invention further relates to a corresponding device (100) and to the use thereof.

Description

technical field [0001] The invention relates to a method for determining the position of objects in road traffic based on communication signals according to the preamble of claim 1 and a method for determining the position of objects in road traffic based on communication according to the preamble of claim 21 Apparatus for position determination by signal and application thereof. Background technique [0002] A wide variety of sensor devices for detecting the environment are known from the prior art. Examples of commonly used sensors suitable for detecting the environment are eg monocular or stereo camera devices, radar devices and ultrasonic devices. It is also known not only to acquire but also to transmit information about the surroundings of the vehicle via wirelessly transmitted vehicle-to-X communication devices. In general, there is a rapid and significant development towards more and more reliable vehicle systems capable of detecting information through a number of...

AI Technical Summary

Problems solved by technology

[0006] However, the methods and devices known from the prior art have the disadvantage that a plurality of different sensors of different sensor types are required for reliable and especially redundant detection of objects, which in turn is associated with relatively high outlays

Furthermore, if information about an object is detected by means of vehicle-to-X communication, it is often necessary to undergo a computationally cumbersome authentication process or to use Environmental sensor information to verify, because malicious emitters may intentionally emit wrong information
