MBD initiatives

This project aims to build a system that enables a simulator to deliver an experience as if one were actually driving on a road by realistically reproducing sounds and vibrations, allowing evaluation of how people perceive sound and vibration while in motion. Beyond merely providing a sensory experience, it envisions concrete application to manufacturing by modeling in conjunction with design parameters.

The impetus for development came from Mr. Matsumoto’s idea of contributing to MBD (Model-Based Development), which is advancing in the automotive industry.
The starting point was his solo effort to investigate and research how to fuse Ono Sokki’s simulation technology with its sound and vibration measurement technology to create a new system focused on human perception. Later, Mr. Kashiwazaki, an expert in sound recording and playback, and Mr. Muraki, who is interested in affective evaluation, joined, forming the current team. Without setting strict role divisions, each member works autonomously according to their interests and expertise.

Yes, at first I started the research and investigation on my own, then combined it with the research content on sound recording and playback that Mr. Kashiwazaki was working on to create a system. Mr. Muraki, who joined us later, is now examining sensory evaluation and the creation of sensory models using that system. I am truly grateful for the various help I have received from both of them.

"We are not progressing solely on our own; we also receive advice from within the company, such as 'Could this be used with existing technology?'"

I was truly grateful that many people participated when we conducted the internal experiment in the past.

At that time, you also provided various pieces of advice, didn't you?

Participants were asked to suggest the use of existing technologies, and some of these suggestions were actually incorporated into the sensitivity model.

Yes. It's often the case that casual conversations lead to connections. I'm very happy that many people listen positively and find it interesting.

I originally worked in mechanical design and had never been involved with simulation or sound and vibration, so I struggled at first due to a lack of basic knowledge. I went through trial and error and faced failures, but I learned while being taught by my seniors. I have a positive attitude towards engaging with things that interest me, so I enjoyed the learning process itself.

I am usually responsible for contracted measurements of sound and vibration, but since this initiative mainly focuses on automobiles, I needed to study issues related to automotive sound and vibration and the frequency ranges involved. Therefore, I have been involved in many automotive-related measurements in my regular work, and I am currently studying to enhance both this initiative and my regular duties.

This is not limited to this initiative, but since we do not actually make cars ourselves, it is often difficult to imagine 'what kind of system would please our customers.' Personally, I find that challenging. However, our senior colleagues have been involved in automotive development for many years, so I want to deepen my understanding by communicating with them and contribute to creating the best systems for our customers.
