[0048] Currently, most ADAS equipment is manually tested one by one for each indicator. This testing method is time-consuming, labor-intensive, and has high testing costs.

[0060] Specifically, the passing standard of the camera test is: if the whole machine test module can receive an image obtained by the camera facing a predetermined calibration cloth, and the image is clear, then the camera is normal.

[0061] In one embodiment, the pass criteria for the voltage test in the PCBA test module and the whole machine test module are: 0.75V node, corresponding to the normal voltage working range of 0.71V-0.75V; 1.0V node, corresponding to the normal voltage working range of 0.9V-1.1V; 1.5V node, corresponding to the normal voltage working range of 1.4V-1.6V; 1.8V node, corresponding to the normal voltage working range of 1.7V-1.9V; 3.3V node, corresponding to the normal voltage working range of 3.2V-3.4V; 5V node, corresponding to the normal voltage working range of 4.9V-5.4V; 24V power supply voltage, corresponding to the normal voltage working range of 10V-26V; if the voltage test results are all within the normal voltage working range of each node or power supply voltage, the voltage test passes.

[0062] In the second aspect, the embodiment of the present application also provides an automated production test method based on ADAS, referring to Figure 3 , the method comprises the following steps:

[0063] S101. Obtain data information of ADAS equipment.

[0064] S102: Perform a performance test on the ADAS device, determine whether the performance of the ADAS device is normal according to the data information, and obtain a test result.

[0065] S103, storing the test results. The test data can be saved in local SQL database and automatically synchronized to the server when there is a network. When necessary, the stored data can be retrieved to generate a test report.

[0066] S104: Display the detection result.

[0067] Furthermore, the performance test specifically includes PCBA test and whole machine test.

[0068] The steps of PCBA testing refer to Figure 4 , including:

[0069] S1021. Record basic information of the PCBA board to facilitate subsequent search.

[0070] S1022, determine whether the power supply of the PCBA board is normal. In the specific test, the operating voltages of each power supply during the test process, including important node voltages 0.75V, 1.0V, 1.5V, 1.8V, 3.3V and 5V, and the PCBA board power supply voltage 24V are obtained through external test equipment, and uploaded to the automated production test system for evaluation to determine whether the power supply of the PCBA board is normal.

[0071] S1023, determine whether the communication of the PCBA board is normal. Mainly includes testing of the serial communication port, CAN communication interface, and software version and hardware version. The CAN interface test is that the external test equipment sends the current and voltage information obtained from the test to the MCU of the ADAS device through CAN. If the ADAS device can normally receive the message sent by the automated production test system, it means that the CAN interface is normal. The serial port test is to use an external test device to send data A to the product through the serial port; the product processes the received data A (such as inverting the data B), and then sends it to the external test equipment through the serial port. If the product can receive the data A sent by the external test equipment through the serial port, and the test fixture can receive the data B sent by the product, it means that the serial port is normal.

[0072] The steps of the whole machine test refer to Figure 5 , including:

[0073] S1021. Record basic information of the whole machine.

[0074] S1022, burning SN information into the whole device and reading SN.

[0075] S1023, judging whether the power supply of the whole machine is normal. The power supply test of the whole machine only includes a power supply voltage of 24V of the whole machine. If it is within the normal working voltage range, it means that the power supply is normal.

[0076] S1024, judging whether the communication of the whole machine is normal, the testing method refers to the testing method of the PCBA board.

[0077] S1025. Determine whether the peripheral components of the whole machine are normal. The peripheral components include speakers, buzzers, buttons and cameras. The speakers, buzzers and buttons can be tested manually to check whether they are normal. For the camera, it is manually determined whether the camera has a picture and whether there are problems such as screen distortion. The camera needs to be facing the predetermined calibration cloth and the image needs to be uploaded to the automated production test system via a USB cable. If the image of the camera is correctly uploaded to the PC and is clear, it means that the camera is normal.

[0078] The ADAS-based automated production testing method provided in the embodiment of the present application can quickly test various indicators of ADAS equipment within 10 seconds, conveniently locate whether various indicators are normal, and has the advantages of simple and convenient operation and the ability to quickly test product quality.

[0079] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
