AI Technical Summary

Problems solved by technology

The alignment procedure performed when assembling the host vehicle does not compensate for pitch or elevation errors due to heavy objects and yaw, azimuth, or roll errors due to misalignment of the host vehicle's wheels or chassis, which may affect the "Capture" or "dog-tracking" of the host vehicle

Embodiment Construction

[0126] Radar alignment is the process of determining the angular misalignment of the radar heading. Correction of these installation errors can be critical to the proper functioning of radar-based tracking methods and most of the features provided by radar sensors that operate on detecting or tracking objects. The two main categories / methods aimed at addressing misalignment are:

[0127] 1) Static alignment methods, which can also be referred to as factory alignment since they require specialized equipment to perform the calibration process; the most commonly used static methods use corner reflectors, Doppler generators, or steel plates;

[0128] 2) Dynamic alignment methods, since they may not require any external (additional) equipment (devices), can also be called automatic alignment. The radar sensor corrects its heading angle based on observations of the environment while the car is moving (i.e., driving).

Abstract

The invention relates to methods and systems for determining alignment parameters of a radar sensor. A computer implemented method for determining alignment parameters of a radar sensor comprises the following steps carried out by computer hardware components: determining measurement data using the radar sensor, the measurement data comprising a range-rate measurement, an azimuth measurement, and an elevation measurement; determining a velocity of the radar sensor; and determining the misalignment parameters based on the measurement data and the velocity, the misalignment parameters comprising an azimuth misalignment, an elevation misalignment, and a roll misalignment.

Description

technical field [0001] The present disclosure relates to methods and systems for determining alignment parameters of radar sensors. Background technique [0002] Radar sensors, for example in automotive applications, need to be aligned with the chassis of the host vehicle in order to know exactly where the detected object is. The alignment procedure performed when assembling the host vehicle does not compensate for pitch or elevation errors due to heavy objects and yaw, azimuth, or roll errors due to misalignment of the host vehicle's wheels or chassis, which may affect the "Capture" or "dog-tracking" of the host vehicle. [0003] Therefore, there is a need to provide reliable determination of alignment parameters. Contents of the invention [0004] The present disclosure provides a computer-implemented method, a radar system, a computer system, a vehicle, and a non-transitory computer-readable medium. Embodiments are given in the dependent claims, the description and t...
