This document describes the corresponding test methods for the driving safety test of intelligent connected vehicles. This document applies to the driving safety test of intelligent connected vehicles with Level 3 driving automation (conditional automated driving) and above as specified in GB/T 40429, including intelligent connected passenger cars, buses, trucks and special- purpose vehicles. Other vehicles with automated driving function shall refer to this guideline.2 Normative references

For the purpose of this document, the following terms and definitions, as well as those given in GB/T 43766 and GB/T 43758.1, apply. 3.1 driving safety test Activity of evaluating the basic driving capability, safe and courteous driving capability, and emergency evasive capability of intelligent connected vehicles using methods such as field test, road test, and simulation test. 3.2 target vehicle; TV Passenger cars, simulators, and other equipment used in conjunction with vehicle under test to complete testing. 3.3 design operational condition A general term of the collective conditions determined during the design of the automated driving system that are suitable for its functional operation. Note 1.The operational conditions for the automated driving system include the operational design domain, vehicle status, driver and passenger status, and other necessary conditions. Note 2.The operational design domain refers to the external environmental conditions suitable for its functional operation that are determined during the design of the automated driving system. Typical external environmental conditions include roads, traffic, weather, and lighting. [Source. GB/T 40429-2021, 2.12, modified]4 Test items
