Embodiment Construction

[0031] figure 1 A schematic diagram of a radar sensor 1 according to the invention is shown, which can also be used as a communication device for vehicle-to-vehicle communication, since the antenna device 2 used is actuated by the control device 3 and can be used both for sending and receiving radar signals , can also be used to send and receive messages within the framework of vehicle-to-vehicle communication.

[0032] It should also be noted here that, for the sake of clarity, components of the radar sensor 1 that are not essential to the invention, such as the filter stage directly upstream of the antenna of the antenna arrangement 2 and the LNA on the receiving side, are not shown here. .

[0033] The radar sensor has a plurality of antennas 4 , 5 as part of the antenna arrangement, including at least one transmitting antenna 4 and at least one receiving antenna 5 . even though figure 1 For the sake of clarity, only one antenna 4 and one antenna 5 are shown respectively...

Abstract

The invention relates to a radar sensor (1) for a motor vehicle (21). The radar sensor at least comprises an antenna arrangement (2) for transmitting and receiving radar signals and a control means (3) designed for controlling the operation of the antenna arrangement (2) and for analyzing and processing the received radar signals, wherein the antenna assembly (2) is operable to transmit and / or receive messages as a part of a vehicle-to-vehicle communication under the driving of the control means (3).

Description

technical field [0001] The invention relates to a radar sensor for a motor vehicle having at least one antenna arrangement for transmitting and receiving radar signals and a control device designed for controlling the operation of the antenna arrangement and for evaluating / evaluating the received antenna signals device. The invention also relates to a motor vehicle and a communication method. Background technique [0002] Radar sensors are widely known in the prior art and are also used in motor vehicles. In which the radar signal is emitted and the reflected radar signal is received again by a usually dedicated antenna of the antenna arrangement, so that the signal can be evaluated by means of an evaluation logic (which can be arranged in the form of a control device in the radar sensor itself), In order to detect other objects and their speeds within the detection range of the radar sensor, for example by observing frequency and phase differences. Other evaluation types...
