캐드앤그래픽스 CNG TV는 19일 ‘미래 모빌리티 혁신, SDV’를 주제로 웨비나를 열고 남창훈 아이피지오토모티브코리아(IPG Automotive Korea) 대표를 초청해 SDV의 개발 환경과 시뮬레이션에 대해 이야기를 나눴다.

SDV functions such as vehicle control, suspension, and sensors are verified through simulation for development code
Demand for high-definition simulation for autonomous driving and ADAS↑… Improved introduction of gaming engines
As software-defined vehicles, or SDVs, emerge as a trend in the automotive industry, the role of simulations that can test various software-driven functions from the development stage is also diversifying, according to industry insiders.
On the 19th, CAD & Graphics CNG TV held a webinar on the topic of 'Future Mobility Innovation, SDV' and invited Nam Chang-hoon, CEO of IPG Automotive Korea, to talk about the development environment and simulation of SDV.
CEO Nam Chang-hoon explained, “IPG companies aim to enable engineers developing electronic controllers to test vehicle modes required during the vehicle development phase through simulations and evaluate them at the full vehicle level,” and added, “Simulations can also be used for evaluations prior to OTA updates, which is a representative technology of SDV.”
Recently, the trend of installing various software in vehicles has become established.There are various development codes such as SIMULINK, C code, etc.
The role of simulation is to enable the developed codes to be tested in the desired vehicle model, in the desired scenario environment, and under various conditions.
Nam predicted that the way automobiles are developed will not change much in the rapidly changing automobile industry environment centered on software.
It is expected that there will be an increased demand for a tool chain that can share related information and connect OEMs, supply partners, and companies operating mobility services.
There is a lot of talk about Devops (Development + Operations), a methodology for quickly releasing and operating software by integrating software development and operations for automotive-related development, but the automotive industry uses a loop-type methodology.
The software development loop in the automotive industry involves testing whether the code is built correctly, assuming that a new piece of software, such as a highway pilot system, is being developed.
At this time, information on the vehicle type is essential and this is a virtual vehicle model called a virtual prototype.
The control logic is linked to this to test various conditions, such as whether the vehicle is staying in its lane.
The cycle (loop) is repeated through testing against various scenarios and then fixing problematic code.
In addition to the controller, it is also possible to test tire characteristics and suspension characteristics according to road friction, and with the development of vehicle technology, various environments are created in simulations to conduct tests in urgent situations, such as when a person suddenly appears in a blind spot.
In line with recent trends in autonomous driving and ADAS, simulations used by engineers There is also a trend toward introducing gaming engines and other improvements to produce high-quality images.
There are clear concerns about information disclosure, as data disclosure on the relevant vehicle model, parts, and software is essential for development and modification through simulation.
CEO Nam Chang-hoon responded, “As software became mainstream, it became possible to conduct evaluations starting from the individual parts, and many countries including the US and Germany had concerns about the disclosure of data.” He added, “We are developing data so that OEMs and partners can test in an integrated environment while protecting IP when exchanging data.”
