Abstract

The invention discloses an ultrasonic radar FOV test table frame calibration system suitable for a passenger door sensing system. The system comprises a DC power supply, an ultrasonic radar test controller, a test table frame, a computer, an all-round work CAN card, an ultrasonic radar, and a test rod, wherein the ultrasonic radar is fixedly installed on the test table frame, and the ultrasonic radar test controller is connected with the DC power supply. The invention relates to ultrasonic radar probe calibration applied to the field of automobiles. By using the test table frame and using the computer to read CAN data in the ultrasonic radar controller, data of the ultrasonic radar for different positions of an object can be measured in real time, ultrasonic radar FOV data can be conveniently obtained, the test efficiency is greatly improved, and the cost and time are saved; and the ultrasonic radar data are read in real time by using the computer, so that the reliability of calibration data is improved, and the requirement for the technical proficiency of testers is lowered.

Description

technical field [0001] The invention relates to the application of ultrasonic radar probe calibration in the field of automobiles, in particular to an ultrasonic radar FOV test bench calibration system suitable for passenger door perception systems. Background technique [0002] Ultrasonic radar probes may sound strange, but they have been widely used in vehicles. For example, the common reversing reminder system uses ultrasonic radar. The difference from millimeter-wave radar is that ultrasonic waves can be reflected by obstacles of any material, millimeter Waves can only be reflected by metal objects, and the detection distance of ultrasonic radar is very short. Among vehicle sensors, ultrasonic radar is currently one of the most common sensing systems. In short-distance measurement, ultrasonic radar probes have great advantages in ranging . It is mostly used in reversing radar or automatic parking. The principle of the ultrasonic radar probe is very simple, that is to u...
