Moray and Ansys to Co-host 2022 KADF
As standards complexity increases, collaboration between companies and institutions becomes essential.

Ansys Korea and Moray held a forum on the topic of SOTIF and simulation for autonomous driving development and evaluation (subtitle: toolchain-based), sharing technologies and trends in SOTIF and autonomous driving simulation.

Ansys Korea and Moray co-hosted the 'KADF 2022 (Korea Autonomous Developer Forum)' at the SKY31 Convention Center in Lotte World Tower, Jamsil, Seoul on the 4th.

KADF is ANSYS' flagship annual event related to autonomous driving, designed to serve as a forum for information exchange to promote cooperation and enhance competitiveness in related industries.

In his welcoming address, Moon Seok-hwan, CEO of Ansys Korea, said, “Global issues and trends are complexly intertwined, and the industry is often greatly affected, so we must prepare accordingly.”uo; and said, “I hope this event will serve as an opportunity to explore ways to strengthen competitiveness in the autonomous driving segment.”

Hong Jun, CTO of Morai, who was the first to present, explained that the simulation was developed to ensure safety during autonomous driving tests, reduce test complexity, and secure data.

Morai continued, “To make the testing more complete, we are conducting co-simulation with Ansys, and when we expand the testing, we are utilizing AWS’s Robomaker and EC2.”

MORAI is also accelerating its mobility platform, including UAM and autonomous ship technology development projects, by seeing the potential of its flagship MORAI SIM function.

While ISO 26262 has been used to develop safety systems related to hardware and software, and is a functional safety requirement to prevent unreasonable risks due to system errors, SOTIF (Safety of the Intended Functionality) is interpreted as 'safety of the intended function' and focuses on dealing with the performance limits of the intended safety function or the system's unintended operation without failure, and foreseeable user misuse.

This is in line with the reason why simulation is receiving attention to satisfy SOTIF.

System testing requires hardware-in-the-loop (HIL) simulation to ensure that the software operates correctly on the target hardware, and SOTIF analysis should include simulation testing to identify hazards.

As the complexity of autonomous driving standards increases, there are calls for collaboration between companies and organizations.

Dr. Jeong Gi-yoon of the Korea Automotive Research Institute, who spoke at the KADF event, said, “Satisfying autonomous driving standards is a task that cannot be accomplished by a single company,” and “Companies and institutions must collaborate and integrate to solve the problem.”

Also, Virtual TestWhen asked whether actual testing could be reduced after going through the process, Dr. Jeong said, “It is not an issue to be decided at the national level,” and also mentioned the importance of actual testing, saying, “Actual testing must be accompanied for export.”

Dr. Koh Han-geom of the Korea Automobile Testing & Research Institute said, “We are supporting the development of technology by providing various evaluation environments through K-City, a self-driving car test city,” and “Through cooperation with Morai, we are developing an environment that is more user-friendly and can reproduce various traffic situations and control infrastructure.”

He continued, “We are conducting demand surveys for various tasks across four government ministries and are working to further develop the test bed,” and expressed his hope, saying, “I hope you will provide us with a lot of input on technology development.”

“ANSYS is supporting multiple teams to use ANSYS medini efficiently with a single tool and reduce costs,” said Lee Tae-hee, an ANSYS Korea professional. “BMW is also using ANSYS tools, and Mercedes-Benz has also worked with ANSYS on scenario optimization and safety analysis.”

ANSYS provides solutions in the areas of Safety Analysis, Scenario Validation, and Sensor Performance with its autonomous driving toolchain.

In the area of Safety Analysis, ANSYS can help design safe models through functional safety, SOTIF, and cybersecurity verification, and through scenarios, it can precisely verify perception algorithms using physics-based sensor solutions similar to real-world sensors.

He said, “With the advent of SDV (Software Defined Vehicle), we have reached a point where no single company can handle everything,” and “ANSYS is also working with several overseas companies to make autonomous driving safer.”
