[0002] In today's era of rapid development in vehicle-to-everything (V2X) technology, Telematics Box (TBOX) devices have become an indispensable component of automobiles. As a communication node for vehicle internet access, the TBOX device enables 4G / 5G network communication capabilities, while simultaneously collecting vehicle information and transmitting it to a backend system, providing convenient query services and user-friendly functions for businesses and users. Crucially, the TBOX device also features an emergency call (ECALL) function, automatically dialing rescue numbers when the vehicle encounters danger, providing timely assistance to passengers.
[0003] However, the development of TBOX devices has presented numerous challenges for testing. Due to differences in hardware configurations across different vehicle models, testers need to prepare multiple test samples and frequently change the samples under test. This leads to low testing efficiency, difficult sample management, and a high risk of test anomalies. Furthermore, existing testing methods have several shortcomings, such as a lack of standardized testing fixtures, inconsistent testing environments, difficulties in hardware fault injection testing, and ECALL testing relying heavily on manual operation, which is inefficient and prone to errors.
[0004] To address the aforementioned issues, this invention proposes an automated TBOX testing device, aiming to improve the testing efficiency of TBOX devices, reduce testing cycle time and manpower input, while simultaneously enabling programmed control of configurable circuits, improving the manufacturing method for hardware fault injection, and automating the entire ECALL testing process.
