Description

A test bench for reversing radar system

technical field

The utility model relates to a test stand, in particular to a test stand for testing a parking radar system.

Background technique

The reversing radar system is a device used to assist parking, consisting of a main controller and a probe. Its working principle is that the probe emits ultrasonic waves, which are reflected back after encountering obstacles. After receiving the reflected waves, the probe returns information to the main controller, and the main controller controls the system to issue visual or auditory prompts. Due to its working principle, the effective working range of the reversing radar system will vary greatly with different vehicle heights and different positions where the sensor is installed. Therefore, it is very important to the performance of the product to use the test bench to simulate the test of different installation positions of the probe, and to carry out reliability verification such as pre-commissioning, performance verification, prototype verification, semi-finished product verification, and finished product verification.

In order to debug the system well and get the optimal parameters, it is necessary to constantly change the position between the probe and the obstacle and test a large amount of data. The current commonly used test method is generally to fix a single probe on the test bench, and then move the position of the obstacle to carry out. The biggest disadvantage of this method is that it can only test the test range of a single probe, and the position of the probe cannot be reflected intuitively. During the debugging process, the adjustment of the height and the change of the angle of the horizontal and vertical directions are also insignificant. It is convenient to record accurately; in fact, the reversing radar system cannot only be composed of a single probe; therefore, such a test method is not convenient, is not conducive to the data recording and effect verification of the test, and does not conform to the actual situation.

Another test method is to test on a real car or using the rear bumper model of the real car, but this method is expensive and difficult to have such conditions; and it is necessary to use corresponding real cars or rear bumpers for different models. The bumper model is tested, similar to the above method, the position of the probe is not easy to adjust, so it is not the best test method in the design and debugging stages.
