Simulation system for accident analysis of autonomous emergency braking device and simulation method thereof

A simulation method for accident analysis of an autonomous emergency braking device, the simulation method comprising:

• inputting virtual driving data including state data about a virtual driving vehicle, a target, and a driving environment to a computing device;
• calculating a relative speed, a relative distance, and an azimuth between the virtual driving vehicle and the target based on the virtual driving data;
• outputting a warning signal or applying a braking pressure to the virtual driving vehicle according to a sequence of the autonomous emergency braking device;
• and
• calculating collision data including a final stopping distance and a collision speed of the virtual driving vehicle,
• wherein the calculating of the relative speed, the relative distance, and, the azimuth includes:
• obtaining a first radar sensor signal, a second radar sensor signal, and a camera sensor signal from the virtual driving data;
• obtaining first fusion data by combining the first radar sensor signal and the camera sensor signal;
• obtaining second fusion data by combining the second radar sensor signal and the camera sensor signal;
• and
• calculating a relative speed, a relative distance, and an azimuth between the virtual driving vehicle and the target based on the first fusion data and the second fusion data.
