Toyoda Gosei Co., Ltd. (TOKYO:7282) has introduced a groundbreaking system designed to allow automotive developers to simulate and evaluate variations in vehicle interior acoustics based on different combinations of sealing components, such as weatherstrips. This new technology aims to enhance the overall comfort of vehicles by improving cabin quietness.
As electric and fuel cell vehicles become more prevalent, their inherent lack of engine noise has shifted the focus to minimizing other types of noise, such as wind and road noise. To address this challenge, Toyoda Gosei has been at the forefront of developing advanced sealing solutions that offer superior sound insulation.
The newly developed system enables designers to assess the impact of various sealing components on cabin sound during the early design phase, before finalizing part specifications for new models. This capability allows for the optimal selection of sealing combinations to achieve quieter cabin environments and reduces the need for extensive modifications during the prototype evaluation phase. As a result, this innovation promises to decrease development time and labor costs.
Leveraging its extensive expertise in sound measurement technology, Toyoda Gosei has incorporated advanced predictive methods, including machine learning and artificial intelligence, into the system. These technologies will enhance the accuracy of sound predictions even before physical prototypes are created. By integrating these predictive capabilities, Toyoda Gosei aims to advance quieter and more comfortable vehicle interiors, ultimately contributing to a more enjoyable and serene driving experience.
