With the development of the "New Four Modernizations" (electricization, intelligence, networking, and sharing), automotive test development technology is facing new challenges. Based on the significance of automotive test development, this paper systematically analyzes the development path of automotive test development technology, focusing on the key technical points of core areas such as the test of the three core electric systems (battery, motor, and electronic control) and safety tests. In response to the test changes brought by new energy vehicles and intelligent driving technologies, this paper proposes countermeasures. The research results show that the collaborative optimization of virtual simulation technology, intelligent testing equipment, and big data platforms is the key direction for the development of test technology. The automation, intelligence, and digitalization of the test development system will help the domestic automotive industry gain a leading position in the fierce global competition.
