The most effective and effective function in vehicle safety is an airbag device. An airbag is a safety device that rapidly inflates to protect the driver or occupants in an automobile accident. The airbag inflates the airbag by generating nitrogen gas when a collision sensor and an electronic control unit detect the amount of impact of the vehicle during a collision and exceed the collision limit. In general, when driving at a speed of about 30 km/h or more, the collision sensor detects and deploys when a strong collision is received from the front or side within 30°. (Each country has different laws and regulations) An airbag is effective in reducing the risk of fatal injury or death in a frontal collision and may not deploy unless a seatbelt is worn as an auxiliary restraint device for a seatbelt. In addition, there are various types of airbags, such as side airbags and curtain airbags, in addition to those mounted on the steering wheel or dashboard. Automotive airbags are manufactured in accordance with the regulations on certification and inspection methods and procedures (Korean Standards, Ministry of Environment Notice No. 2021-118) and the regulations on manufacturing automobile test inspections and procedures (Korean Standards, Ministry of Environment Notice No. 2022-73). You must undergo an authentication test. In order to receive a certification inspection, you must follow the vehicle certification test and inspection work procedures of the Korea Environment Corporation. A similar certification procedure exists internationally. The cost of certification inspection varies depending on the type of vehicle and test items, but generally costs between several million won and tens of millions of won. The certification inspection time varies depending on the condition of the vehicle and the test items, but generally takes several days to several weeks. In the case of verification through a verification environment through Hil, it is difficult to configure the same environment as an actual vehicle crash test. The disadvantage is that the range of motion for simulation of impulse and ACU movement is small, and it is difficult to accurately simulate the numerical or quantitative values desired by the tester. The virtual verification environment is a simulation platform that emulates the automobile SW platform, system, and vehicle dynamics model as a digital twin and can pre-verify SW logic and vehicle functions. Compared to the Hil verification environment, it has the advantage of configuring an environment identical to reality and being able to verify by simulating shock amounts and ACU movements at a level similar to reality. Through this, time and cost savings can be expected as mentioned above.
