Abstract

The present invention relates to a method for simulating an autonomous vehicle in a virtual environment, as a moving body simulation method, comprising: a simulation preprocessing step in which a first server generates environment information within a predetermined time, the environment information comprises at least one of simulation object road information, surrounding vehicle information, surrounding pedestrian information, surrounding obstacle information, surrounding traffic signal lamp information, surrounding signboard information and event information; and a simulation step in which the second server calculates sensor unit output data of the vehicle to be simulated, which is generated on the basis of the travel of the vehicle to be simulated, by using the environmental information within the predetermined time, thereby improving the quality of algorithm verification while preventing overload due to resource restrictions of the server.

Description

technical field [0001] The present invention relates to a method for simulating a self-driving vehicle in a virtual environment, and in more detail, to a simulation method in which, in a simulator of a self-driving vehicle that is a virtual environment for verifying a control algorithm of a self-driving vehicle, by efficiently data processing to keep resources optimized. Background technique [0002] A self-driving vehicle is a car that can run without a human driver directly driving the vehicle. Such self-driving vehicles usually follow a driving route based on two-dimensional / three-dimensional map information, measure surrounding objects in real time during driving, and change the driving route if a change occurs. [0003] In addition, the above-mentioned self-driving vehicle performs automatic driving based on the data recognized from the surrounding terrain features and the driving control algorithm that processes it. In the case of the above-mentioned recognition, the ...
