Gelonghui, April 16 | Sinotrans (601598.SH) said on an interactive platform that 1) The level of L4 autonomous driving is divided into R&D tests, demonstration applications, and large-scale commercial implementation from the perspective of implementation applications. Currently, Qingyi Company's L4 is in the demonstration application stage. Implementation applications are being carried out on some demonstration routes to refine autonomous truck technology and processes with actual business requirements. 2) L2 and L4 are fundamentally different on the technical route. First, L2 autonomous driving realizes partial autonomous driving in specific scenarios. It requires the driver to always pay attention to the driving environment and take over vehicle control (such as blurred or unrecognizable lane lines) when prompted by the system. The software and hardware requirements are lower than L4 level. On the other hand, family cars are a consumer market, and the current L2 solution can basically meet current market needs with a high cost performance ratio. Since its inception, Qingping Company has focused on the practice of L4 level autonomous driving. Through in-depth cooperation with My Little Pony Zhixing, Sinotrans has continuously promoted technological innovation and breakthroughs, and has obtained autonomous driving licenses from all first-tier cities. 3) The level of autonomous driving in the logistics industry is no different from that of everyday passenger cars. They are all divided according to the automobile driving automation classification standards set by the Ministry of Industry and Information Technology in 2021.
