Benefits of technology

[0050]Many commercial IMU's are now manufactured in excellent quality and large quantities. As a result, they tend to be currently available at reasonable prices. This way, as in some embodiments of the presently-disclosed technology, it is economical to design for, specify, and use commercially-available IMUs, even if not all available functions of the commercially-avail

Problems solved by technology

Also, it may account for errors due to movement/displacement of the radar object-detection package resulting from impact damage, or errors resulting from wear-and-tear or failure of any of the securement components for the radar package on

Embodiment Construction

Referring to the Figures:

[0062]In the generalized schematic flow-chart diagram of FIG. 1, there are depicted in outline form several process steps, which a reasonably-skilled person in the art of vehicle object detection radar systems may understand and utilize for radar-based object detection. Said reasonably-skilled person in the art also will understand, once this document and the drawings have been reviewed, how to incorporate, into the process of FIG. 1 and the equipment represented by FIG. 1 and / or known in this field, methods and apparatus according to embodiments of the invention for practicing improved calibration of a radar sensor system and the resulting improved on-going operation of the radar sensor system.

[0063]In the schematic top detail perspective left side view of FIG. 2, radar object-detection sensor package (or “unit”) 10 with built-in IMU 12 is attached to vehicle left side surface 15. The package 10 comprises IMU 12 having exterior face 16 and being operatively...

Abstract

The disclosed technology is a vehicle object detection radar system incorporating an inertial measurement unit (IMU). The IMU may obtain input signals of, or relating to, for example, relative motion, acceleration, object detection angle, sway and vibration of the vehicle and/or any towed trailer, and process them for relay to the vehicle operator as operating information and possibly alarms. Also, the obtained IMU signals may be relayed directly to the vehicle's object detection radar systems and central control for automatic adjustment and control thereof.

Description

DESCRIPTION[0001]This application claims benefit of Provisional Application Ser. No. 63 / 123,730, filed Dec. 10, 2020, entitled Calibration of Vehicle Object Detection Radar With Inertial Measurement Unit (IMU), and claims benefit of Provisional Application Ser. No. 63 / 123,777, filed Dec. 10, 2020, entitled Operation of Vehicle Object Detection Radar With Inertial Measurement Unit (IMU), the entire disclosures of both Provisional Applications being incorporated herein by this reference.BACKGROUND OF THE DISCLOSED TECHNOLOGYField of the Disclosed Technology[0002]This disclosed technology relates generally to vehicle object detection radar systems. More specifically, this disclosed technology relates to such radar systems incorporating an inertial measurement unit (IMU) to detect, and if necessary, enable the vehicle's operator or the vehicle's automatic monitoring and control systems to adjust to issues resulting from inaccurate installation of, or impact damage to, for example, the r...
