Title:
MISALIGNMENT DETECTION FOR A VEHICLE RADAR SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/186868
Kind Code:
A8
Abstract:
The present disclosure relates to a vehicle radar system (2) that is arranged to detect a plurality of objects outside a vehicle (1) and that comprises a radar detector (3) and a processing unit arrangement (4). The processing unit arrangement (4) is arranged to obtain at least one total detection angle (φdT, φατ' ) relative an x-axis (7) and at least one corresponding detected target Doppler velocity ( vDoppler) relative the radar detector (3) for each detected object (5, 6; 10,11). Each detected object is classified as moving or stationary, and a relation is determined between the stationary detections and the total number of detections. The processing unit arrangement (4) further is adapted to determine whether the radar detector (3) is misaligned based on said relation, where the total detection angle (φdT, φdτ' ) equals the sum of a known mounting angle (φm) between the x- axis (7) and the radar detector' s mounting direction (8 ), and a detection angle (φd, φd' ). The present disclosure also relates to a corresponding method.
