Embodiment Construction

[0030] In the various drawings, the same parts have the same reference numerals; therefore, they are usually only described once.

[0031] figure 1 A security system 1 according to the invention is shown. In the safety system described above, the sensor unit 3 and the control unit 4 connected thereto are installed in the passenger vehicle 2 . The sensor unit 3 is configured to radiate a detection signal D containing a detection frequency within the radar range. The detection frequency may be eg 24 GHz, where other frequencies are of course possible, and the detection signal D may also contain multiple detection frequencies. If the detection signal D hits a regular object (e.g. a tree 10), this leads to reflections, where the reflected signal R matches the detection signal D except for a Doppler shift in frequency, which can be, for example, in the tens of tens or in the 100 Hz range.

[0032] However, various objects such as another passenger car 11, a bicycle 12, a pedest...

Abstract

The invention relates to a safety system (1) for a motor vehicle (2), the safety system (1) comprising an on-board vehicle sensor unit (3) configured to transmit a detection signal (D) comprising at least one detection frequency in the radar range; the on-board vehicle sensor unit (3) is configured to receive a response signal (A) returned from the object (11 to 14) and containing at least one response frequency, the on-board vehicle sensor unit (3) being configured to associate the at least one response frequency with one detection frequency, thereby detecting the object (11 to 14). In orderto enable the safety system for a motor vehicle to reliably detect obstacles, at least one response frequency differs by at least 5% from the detection frequency associated therewith.

Description

technical field [0001] The invention relates to a safety system for a motor vehicle having the features of the preamble of claim 1 . Background technique [0002] Many modern vehicles have an Autonomous Emergency Braking (AEB) system that autonomously initiates a braking action to avoid a collision with an obstacle (such as another motor vehicle, pedestrian or bicycle) located in the direction of travel . Such AEB systems typically identify vehicles, bicycles, and pedestrians based on motion patterns (eg, legs in motion) or specific silhouettes with the aid of cameras and / or radar sensors. However, reliable detection is difficult because reflections, 2D patterns of the surrounding environment, and noise can cause radar as well as cameras to identify objects that are not there (ghosting), leading to false positive results. To address this, very stringent requirements are usually required to identify obstacles before automatic braking maneuvers can be performed. For example...
