To ensure its reliable operation, stability, and excellent driving experience, comprehensive functional and performance testing is required. Responding to the development and verification needs of intelligent cockpit domain controllers, an automated testing system has been designed and developed, aiming to provide an efficient and reliable solution. By analyzing the system testing requirements, corresponding test cases were established, and the overall structure of the automated testing system was designed. In the system implementation, a cabinet-style integrated structure was adopted, with a modular design for core components. Key components and integration technologies such as industrial computers, DC power supplies, data acquisition systems, signal generators, load boxes, and communication modules were innovatively added, achieving excellent automated testing results. With the updating and iteration of intelligent cockpit domain controller technology and functions, pre-research was also conducted on the expansion of LVDS video injection and acquisition, broadcast signal simulation and multi-channel communication protocols, and HMI automated testing system modules, providing important technical support for the forward-looking technology development, testing, and verification of intelligent cockpit systems. This system not only realizes modern automated testing functions but also possesses manual mode operation and functional inspection testing, providing effective guarantees for the stability, reliability, and performance optimization of intelligent cockpit systems.展开更多
