Realising ‘IoT Tyres’ means installing various sensors inside of a tyre in order to collect and transmit information from the tyres to the vehicle, where this information can then be used in various applications. As these sensors require batteries or other sources of energy to operate, we believe that it makes perfect sense to power these devices using the energy produced naturally by the rotation of a tyre: Kazuhisa Fushihara, Manager, Planning & Administration Dept., Research & Development HQ, Sumitomo Rubber Industries
Cutting edge technology researches are on overdrive to enhance the performance of a tyre that can fit into the future definition of mobility, which revolves around sustainability. Tyre as a totally autonomous entity even while being the most vital element in a vehicle is among the ultimate goals of designers and technologists – tyres that can operate on its own, depending less on the mother vehicle, ensuring safety to the user and adding high level of value to strengthen the vehicle’s performance.
Surface friction and rolling resistance have always been the focus of tyre makers. A high amount of heat and energy are being generated during a tyre’s roll on the surface. Making use of this to sustain its function has been a major aim of technologists. Sumitomo Rubber Industries’ (SRI) “Energy Harvester” answers to this effort in a big way.
In mid 2019, Sumitomo, through joint research undertaken with Professor Hiroshi Tani of Kansai University, developed this new technology to generate electric power from the rotation of a tyre. This is accomplished by installing a power generating device (Energy Harvester) inside of a tyre to convert static electricity occurring within a tyre into clean energy. This new device takes advantage of a type of static electricity called “frictional charging” to generate electric power efficiently each time a tyre's footprint deforms as a tyre rotates. Sumitomo, the parent company of Falken Tyres, believes that this technology holds great potential for practical applications as a power source without needing batteries for various automotive digital tools, including in TPMS (Tyre Pressure Monitoring System) and other automotive devices.
The research was selected by the Japan Science and Technology Agency, national research and development agency, as a Type FS Seed Project under A-STEP (Adaptable and Seamless Technology Transfer Program through Target-Driven R&D). Sumitomo Rubber Industries will now advance this research with support from the Japan Science and Technology Agency.
Sumitomo has been engaged in a wide range of joint research studies with various universities, including Kansai University and Gunma University Center of Research among others, on sustainability projects.
Regarding the project on “The Development of Intelligent Tyres Using Friction-Charged Sensors,” Kazuhisa Fushihara, Manager, Planning & Administration Dept.,
Research & Development HQ, Sumitomo Rubber Industries, told Tyre Trends: “We are afraid that we are unable to comment on the scope of this joint research project, or other areas of joint research with Kansai University, due to the existence of a non-disclosure agreement. However, we can say that, with backing from the Japan Science and Technology Agency (JST), we are actively engaged in research and development that envisions future tyres that fully incorporate IoT technology.
‘In-house’ energy source
On Energy Harvester Technology, Fushihara said that “Kansai University carried out the basic research and development for the underlying technology before engaging in joint research and development with our company toward realising applications for this technology in tyres.
Developing energy sources within tyres/vehicles goes a long way in ensuring sustainability in product manufacturing. The degree of energy saved is directly proportional to the reduction of energy used from external sources, including fossil-based sources.
Fushihara said: Realising “IoT Tyres” means installing various sensors inside of a tyre in order to collect and transmit information from the tyres to the vehicle, where this information can then be used in various applications. As these sensors require batteries or other sources of energy to operate, we believe that it makes perfect sense to power these devices using the energy produced naturally by the rotation of a tyre.”
Maintaining right pressure in tyre plays a major role in its performance. “We believe that tyre pressure monitoring systems are an enormously beneficial technology, which is why the EU, China and many other countries around the world have followed the lead of the United States in making TPMS a regulatory requirement. Maintaining appropriate tyre pressure is extremely important in terms of both safety and the environment and, with an eye toward the future of automated vehicles, we believe that it is safe to say that TPMS will only become more and more important in the coming years,” Fushihara observed.
He added: “In the future, we hope to add even more value to these kinds of systems by augmenting their functionality so that they are able to detect not only tyre pressure, but also conditions at the point of contact between tyre and road as well as tyre load and other operational factors.”
Sensing Core
“The Sensing Core Technology that we are currently developing is yet another example of the Sumitomo Rubber Group’s efforts to enhance the value of TPMS so that we may provide greater safety and peace of mind to the increasingly automated mobility society of the future.”
The Sensing Core, a new tyre sensing technology, can detect road conditions, tyre load and other information by analysing the wheel speed signals that are generated by the rotation of the tyres.
SRI has already perfected its proprietary DWS (Deflation Warning System) technology, which analyses wheel speed signals from the rotation of tyres to detect and notify the driver of decreases in tyre air pressure. The DWS technology has been adopted by many automobile manufacturers and can now be found as a factory standard feature in countless vehicles throughout the world, the company website said (information and image courtesy: srigroup.co.jp).
Based on the technical knowhow that SRI cultivated in the development of DWS, the Sensing Core is the next evolution in DWS technology, an advancement that eliminates the need for an additional, dedicated sensors by instead utilising cutting-edge software to detect tyre pressure directly from existing wheel speed signals, thereby reducing the cost of installation and eliminating the need for maintenance.
As the only part of a vehicle that comes into direct contact with the road, tyres must support a vehicle’s entire weight. The Sensing Core technology uses a proprietary algorithm to detect various types of information based on what we know about each specific tyre so that this information can be shared with the driver and with the vehicle itself. This advanced algorithm incorporates and takes full advantage of SRI’s extensive knowledge of various tyre properties, which the company gained through over 100 years of experience in tyre development.
