Abstract

The embodiments of the invention provide an automatic driving simulation test system and method. The sensor target information, transmitted by a virtual scene module, of a target virtual scene is obtained through a sensor module in the simulation test system, the state parameters of a virtual vehicle in a simulation test process are obtained through a positioning module, a vehicle actuator modulegenerates an automatic driving instruction aiming at the state parameters according to the sensor target information, a dynamics module controls the virtual vehicle to execute a simulation test corresponding to the automatic driving instruction to generate a simulation test result, then a state feedback module generates test feedback information by adopting the simulation test result, and a closed-loop simulation test is formed. According to the simulation test system, functions executed by different modules in the automatic driving process of the vehicle are simulated and tested, the reliability and the operation efficiency of the automatic driving test can be effectively improved, developers can conduct technical research and development under the support of credible data, and the efficiency of algorithm iteration in mass production is improved.

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...
