The system includes an antenna, a transceiver, and a controller. All rights reserved. Also, this initial calibration does not compensate for changes of response due to aging or changes in environmental conditions, which can and often do lead to deterioration in system performance. ��C]�s�Ƃ�GWE?$k^�Dn�.�l��s�>l�/���ŕurn�D�5�i~S?�(���zj�X�ys��I�[#�)���dgq��NH1H�����'�h���>Z��oʿϟ}����H���ҕ���M�T�%���^��W���.F��k�b��nOe�{�K�oKzyd C� ���.��d��� �wD%�?������̕d�>(����j$] Aptiv Technologies Ltd has 200 total employees across all of its locations and generates $7.71 million in sales (USD). endobj As such, the calibration may not be optimal as the calibration does not compensate for the effects of the fascia, frame, or other features of the host-vehicle that may influence the response of the radar system. %���� The transceiver determines a distance, an angle, and a range-rate of the object relative to the antenna based on the radar-signal and the reflected-signal. The transceiver determines a distance, an angle, and a range-rate of the object relative to the antenna based on the radar-signal and the reflected-signal. %PDF-1.5 The range of physical angles of the stationary object depends on its relative position with respect to the host-vehicle, which is tied to the initial range. The antenna is mounted on a host-vehicle. 4 is a top-edge view of an antenna used by the system of FIG.

An automated vehicle radar system capable of self-calibration includes an antenna, a transceiver, and a controller. There are 204 companies in the Aptiv Technologies Ltd corporate family. CMC Engine Management System. 2A and 2B is an illustration of the relative locations of a host-vehicle equipped with the system of FIG. endstream In the calibration mode, the system may be switched into a sensing mode which gives it the highest Doppler resolution that is appropriate with the vehicle speed. Box 5052 endobj This can be based on miles traveled, weather changes, a time-interval (periodic), or a time-delta from the initial time of sensor operation. The calibration can be performed while the host-vehicle is traveling throughout the operating lifetime of the system.
However, when the object is at the 40 degrees, the Doppler resolution only needs to be 185 mm/s. 4 illustrates a non-limiting example of the antenna While this invention has been described in terms of the preferred embodiments thereof, it is not intended to be so limited, but rather only to the extent set forth in the claims that follow.

The controller determines a speed of the host-vehicle; determines when the object is stationary based on the speed, the angle, and the range-rate; stores in a memory a plurality of detections that correspond to multiple instances of the distance, the angle, and the range-rate as the host-vehicle travels by the object; selects an ideal-response of angle versus range-rate based on the speed; determines a calibration-matrix of the system based on a difference between the plurality of detections and the ideal-response when the object is stationary; and adjusts an indicated-angle to a subsequent-object in accordance with the calibration-matrix.Further features and advantages will appear more clearly on a reading of the following detailed description of the preferred embodiment, which is given by way of non-limiting example only and with reference to the accompanying drawings.The present invention will now be described, by way of example with reference to the accompanying drawings, in which:FIG.

M/C 483-400-502, Troy, MI, 48007-5052, US) This provides for a more precise calibration of the system even as parts of the system or the host-vehicle change (e.g. CMC is one of the most popular interfaces for Engine Management and Electronic Control Units in the automotive industry because of its compact size, high density connectors, sealed connection systems for Electronic Control Units application and lastly it is suitable for harsh environment
