Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to an automatic driving simulation test system and an automatic driving simulation test method. Background technique

[0002] With the development of autonomous driving technology, the automatic driving functions of vehicles are becoming more and more mature. Vehicles operating in autonomous driving mode (eg, driverless) can free occupants, especially the driver, from some driving-related duties. Among them, automatic driving can include different stages of technology such as L1-L5. With the improvement of the stage level, the automatic driving technology becomes more mature. Algorithm function testing at the current L2-L3 stage of autonomous driving involves the investment of modified vehicles, scenario planning, testers and equipment, resulting in low efficiency of the actual vehicle test method and long test cycle, which greatly affects the efficiency of autonomous driving techn...
