Also helps to reduce worker-hours by
proposing the optimum combination of parts
Toyoda Gosei Co., Ltd. (TOKYO:7282) has developed a new system
that enables automotive developers to experience changes in vehicle
interior sounds with different combinations of the sealing parts
(weatherstrips) installed on those vehicles. This contributes to
the creation of more comfortable moving spaces through improved
quietness in cabin.

The electric vehicles and fuel cell vehicles that are coming
into wider use are quieter than traditional vehicles since they are
driven by motors and have no engine noise. This means that more
wind noise and road noise reach the ear, and demands better sound
insulation parts. To meet these needs, Toyoda Gosei has been
developing high performance sealing parts.
The company’s new system makes it possible, in the design
concept stage before deciding the shape of parts for new models, to
hear driving sounds with sealing parts under development installed.
This will lead to proposals for the best combination of sealing
parts for the creation of quieter cabin space. It also helps to
minimize the design changes in parts that have traditionally
occurred following performance assessments of prototype vehicles,
which is promising for the reduction of development
worker-hours.
This system was achieved with the assessment technology using
actual measurements of sound that Toyoda Gosei has cultivated up to
this time. The company is planning to further raise the predictive
accuracy of the new system by combining machine learning with
artificial intelligence, to predict and reproduce how sound will be
heard even before part prototypes are made. By proposing parts that
raise quietness in the early stages of vehicle development, Toyoda
Gosei aims to contribute to quieter and more comfortable mobility
in society.
