2022 Automotive Tech Concert Viewer Q&A
Research on hardware-in-the-loop simulation systems

Morai announced that it is currently collaborating with domestic automobile OEMs and Tier 1 companies.

Park Hyun-jin, Group Leader of the Moray Software Module Group, answered questions that could not be answered due to time constraints during the presentation on 'Precision Road Map Utilization and Seoul City Autonomous Vehicle Simulator' at the 2022 e4ds Automotive Tech Concert on the 7th.

■ Morai's simulation error investigation and research and development

The most common error investigation involves observing the plant's response to identical control commands. After conducting identical tests in real and simulated environments, the collected data is compared and analyzed. Similar data and discrepancies are examined in each data interval, and models are then modified to minimize them.

Based on our experience acquiring data from tests conducted in actual fields or test sites, we are developing and researching a toolset that can extract various parameters and data trends from the data and then reflect them back into simulation models. Additionally, we are researching a hardware-in-the-loop simulation system that links with actual equipment to address the lack of virtual data.

■ Best Practices of Morai Simulation

MORAI SIM: Drive is cited as a best practice. Its greatest strength lies in its ability to digitally recreate and simulate diverse real-world driving environments, tailored to the needs of customers. Its ease of use and powerful data processing tools make it accessible to everyone from students to working engineers. It has already been provided to numerous domestic universities, research institutes, and companies, where it is being applied in actual testing processes.

■ Can road conditions and weather be reflected in the simulation?

This feature was considered from the early stages of development, as it is the most frequently requested feature in simulations. It changes based on user input, such as weather, time, and road conditions, and impacts the actual driving and sensor data acquisition system.

■ I wonder if collaboration with the domestic automobile industry is possible and whether the content presented in the webinar is actually being applied in the automobile industry.

Morai is currently collaborating with domestic automotive OEMs and Tier 1 companies. Furthermore, the simulation testing processes presented in the webinar are technologies already actively being used or adopted in the autonomous driving industry.

■ What support is needed to build an autonomous driving simulation?

Building a good simulator requires a large amount of high-quality data. To give a simple example, the various elements involved in creating a range environment must be structured in a way that makes sense to the user. △The more accurately the location of the traffic light, the composition of the actual signal, and the operating cycle of the signal are reflected, the more meaningful the test results can be.

Meanwhile, the second session of the 2022 e4ds Automotive Tech Concert will be held on the 14th with the theme of 'Trends in Standardization of Precision Road Maps for Autonomous Driving', and Jaejun Yoo, a senior researcher at ETRI, is scheduled to speak.
