ADAS is also known as the assisted driving system, and the technical conditions at this stage refer to the L2 level of assisted driving. Although the ADAS functions of various car brands are not the same, there is basically not much difference.
But if the seatbelt is unfastened in ADAS, will the ADAS continue to be maintained, or will it be released immediately? Each car brand is not the same correspondence. Tesla will forcibly eliminate the feature, and Hyundai Motor Group's vehicles will maintain ADAS.
Tesla models, when Autopilot is enabled, emit a red warning pattern and a loud warning sound when the seat belt is released. A warning message will also appear stating that the autopilot function has been removed. This means that the "Traffic Sense Cruise Control" that maintains the distance between the vehicle and the vehicle in front and helps stop if necessary and the "Auto Steering" that keeps the vehicle center in place will all be unusable.
Tesla's starting point for doing so is to believe that seat belts are the basis of all safety, and if seat belts are not fastened, then there is no point in using ADAS functions.
But what about vehicles belonging to the Hyundai Motor Group? If you unfasten your seatbelt when highway driver assistance (HDA) is enabled, a warning sound and a seatbelt warning light will appear on the digital dashboard or dashboard that the seatbelt must be re-fastened. However, the ADAS function will continue to be maintained, waiting for the driver to actively fasten the seat belt.
The starting point of modern cars is that the seat belt is either untied unconsciously by the owner or has to be unfastened because of an emergency. If the ADAS function can no longer be used at this time, then the driver will be more dangerous. So the user will be prompted with a sound and dashboard first, and then the ADAS function will be maintained. Does not cause more inconvenience to the user.
In fact, the current laws of various countries do not stipulate what ADAS should do when the seat belt is unfastened, so there will be certain differences in the seat belt warning system of each manufacturer.
The recent tesla thing is that if the driver does not fasten his seat belt, then the warning sound will not sound.
The recall document released by the National Highway Traffic Safety Administration says the problem only occurs when the driver leaves the vehicle during the previous driving cycle and the bell rings.
Tesla will address this issue earlier this month with an over-the-air software update. If the bell is not ringing, drivers may not know that their seat belts are not fastened, increasing the risk of injury in a crash, the safety agency said.
The company said in the filing that it was not aware of any collisions or injuries caused by the problem. Visual seatbelt reminders are still displayed.
The Korea Automotive Testing and Research Institute discovered the problem on January 6. Tesla investigated and determined that a recall was required on Jan. 25, the filing said.
According to test results from the Automotive Safety Research Institute of the Ministry of Land, Infrastructure, Transport and Tourism, tesla motors' system does not comply with U.S. safety regulations. In the United States, when a vehicle is started and confirms that the driver's seat belt is not fastened, a warning sound is immediately sounded.
For Hyundai Motor Group brand vehicles, even if it is confirmed that the seat belt is not fastened during highway assisted driving, the ADAS function will not be immediately removed.
Tesla plans to address this issue through over-the-air software updates (OTAs) within this month.
