Creating the future of autonomous driving with chemical materials by uncovering hidden needs in this field. Creating the future of autonomous driving with chemical materials by uncovering hidden needs in this field.

Untapped needs still exist for the devices and precision equipment that support the realization of autonomous driving. By knowing the current situation of what technology is necessary for autonomous driving, a glimpse of the role that each manufacturer plays comes into view. Naoki Suganuma is an associate professor at Kanazawa University, which in 2015 became the first university in Japan to conduct verification tests for autonomous driving on public roadways. He joins Nobuhiro Shinka, Marketing Department Manager in the Chemicals Division at Daikin Industries, to discuss what chemical manufacturers can do in the field of autonomous driving.

The Chemicals Division has a research center in San Jose, United States. Here we have committed resources to activities in pursuit of advanced technologies to leverage the special properties of chemical materials, including applications for autonomous driving and life science. Professor Suganuma, during your approximately 20 years of conducting research on autonomous driving, have you ever collaborated with overseas research institutes?

Suganuma

I’m a member of various international societies and participate in international conferences where information is exchanged. Because we have roughly much of technology, we perform peer reviews and are able to learn the general trends of laboratories with cutting edge research.

Shinka

When looking from a global perspective, which country do you think the manufacturers are one-step ahead?

Apart from the information that a manufacturer discloses to the media, manufacturers generally do not provide details. In the scientific community, there is a strong impression that U.S. and German manufacturers are more active in announcing results. European and American manufacturers typically have people engaged in research who have doctorate degrees. Unfortunately, in Japan, rather than conducting research from the aspects of tangibles and intangibles, cars belong to the world of engineering and are regarded as a mature field of study.

Expertise of chemical manufacturers necessary to refine sensors and radar

Recently, there have been many incidents of elderly people mistaking the accelerator for the brake. Just preventing this would be meaningful for society. Do you have any advice for how chemical manufacturers can contribute in the field of sensors for autonomous driving to eliminate this problem?

Suganuma

One example would be the great need for technology that automatically cleans dirt and stains on sensors and makes it difficult for sensors to get dirty in the first place.

When driving several hundred kilometers on the highway, there are many cases of hordes of insects sticking to the car. Because the stain sticks on the sensors, there is a need to equip sensors inside the car. However, because of the glass window surfaces, reflections occur. Even in the case of cameras, the light entering the camera generates a diffused reflection between the glass surface and the lens, making it difficult to see. There is even a demand to transmit only the light of the signal component you want to see. When speaking of “visibility,” the visibility of a sensor differs from that of a person. Consequently, there are many ways that a chemical manufacturer can contribute such as technological development that makes it easy for sensors to detect the necessary light.

Our fluorochemicals have the characteristic of being stain-resistant as seen in the case of the coating used for fry pans. Additionally, we also have put efforts into technological development of surface functional materials for controlling reflection, improving surface repellency, hydrophilicity, and durability, and hardening surfaces. Processing technology, including analysis and evaluation, is naturally Daikin’s strength and is used in prevention of camera-related fouling, optical control, and optical fiber materials.

Because visibility as seen by the human eye is easy to evaluate, it is being incorporated into material design, but in the future it will be necessary to evaluate and analyze by combining from the standpoint of visibility as seen by a sensor.

Suganuma

Manufacturers involved with sensor devices and signal processing are searching for materials and chemical components corresponding to the special characteristics of sensors. Because the product development cycle becomes quicker when these manufacturers can effectively collaborate with chemical manufacturers from the initial design stage, I think it is a very good flow.

From the university perspective, there are many opportunities for us to consult with a variety of companies. Companies that practice open innovation give us the impression that they have materials with a bright future.
