Nexen Tire announced that it has developed an Artificial Intelligence (AI) and big data-driven methodology that can help reduce tyre noise.
The big data research for Noise, Vibration, and Harshness (NVH) was jointly conducted with Hyundai-Kia Automotive Group and Inha University in Korea.
Since 2018, Nexen Tire conducted the joint research with long-standing partner Hyundai-Kia Automotive Group to increase customer satisfaction and improve the environment by reducing noise levels. More importantly, the research is set to make an impact that can help reduce research and development (R&D) time period and costs.
Due to worldwide regulations the increasing trend on noise reduction for electric vehicles, Nexen Tire set up an anechoic chamber containing dozens of microphone sensors to measure noise, analyse pass-by noise (PBN), and detect causes of noise from vehicle powertrain. In addition, Nexen Tire created Korea’s first 4-drum research equipment facility and is currently conducting tests with actual vehicles. The results of the braking test performance on snow, hydroplaning, and wet surfaces were successful with the technology that includes AI and Big Data; internal and external noise generated by cars can be reduced to 1 dB (decibel) and 3 dB (decibel), respectively.
Nexen Tire will continue to invest in research and development and other forms of joint research such as enhancing NVH performance of autonomous vehicles by using advanced technologies like AI and big data in readiness for the Fourth Industrial Revolution.
