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.

From Data Overload To Decisive Action

Webfleet

As commercial vehicle operators face mounting pressure from regulations, rising costs and the shift to electric power, Webfleet, a subsidiary of Bridgestone, is focusing on turning ever-growing volumes of vehicle data into practical recommendations that improve performance and ease the daily burden on fleet managers.

Founded in Leipzig in 1999 as one of the world’s first web-based fleet management platforms, Webfleet has grown from a pioneering software-as-a-service (SaaS) start-up to Europe’s leading solution and a core part of Bridgestone’s global offering. Today it serves drivers across more than 180 countries with AI-powered insights, electric-vehicle tools and sustainability data that turn complex operations into clearer, more efficient decisions.

In an exclusive interaction with Tyre Trends, Marc Notenboom, Director of Product Management at Webfleet, shares how the company has watched the fleet-management sector evolve over more than a quarter of a century. Interestingly, it was just last year the company marked its 25th anniversary.

From its inception, Webfleet has seen the volume of available data explode, yet the real challenge remains converting that information into meaningful guidance.

“Fleets give you more data but not more insights, which continues to be a challenge. Because of new regulations, new sensors, increasing competition and customer demands, we end up generating more data. We also have access to more data, which is growing exponentially. And then comes the real question, how do you make sense of that data?” Notenboom observed.

Marc Notenboom, Director of Product Management, Webfleet

Webfleet obtains its information through black-box devices installed in vehicles, sensors or direct connections to original-equipment manufacturers. This includes telematics, GPS, video, driver behaviour and vehicle diagnostics, among others. The company then processes that stream to deliver fleet-management services.

The next step, he explained, is moving beyond retrospective analysis. “Insights tell you what happened and why it happened, perhaps, but not what you need to do to improve your performance. That is what we are doing now with the help of artificial intelligence (AI). For example, we analyse data, see if patterns are different or you have anomalies in your data to predict what is happening or what is going wrong. And then we also use AI to analyse our data to see how you are performing, for instance, against competition. And then give customers suggestions on how to improve on certain topics like fuel consumption or driver safety,” he said.

The industry, in Webfleet’s view, is therefore evolving from raw data collection towards insights, recommendations and concrete actions.

SHARED PRESSURES ACROSS DIVERSE FLEETS

Webfleet serves a wide spectrum of customers, from large transport and logistics operators to small fleets of one or two vehicles, service-and-maintenance businesses and last-mile delivery companies.

Each customer faces distinct operational issues, yet common themes emerge. “What they all have in common is that the amount of data and the pressure to enhance their performance is increasing a lot. And then there is the regulatory compliance pressures as well,” said Notenboom.

Performance, in this context, covers delivery times, cost per kilometre, driver wages, safety and fuel consumption – metrics that matter differently according to the sector, but all that demand continuous improvement.

One of Europe’s most persistent difficulties is the shortage of skilled drivers, which has led to greater reliance on migrant workers whose experience of road conditions may vary widely between countries.

Webfleet addresses part of this challenge through tools such as OptiDrive, which shows fleet managers how individual drivers perform on fuel use and safety. Language barriers are tackled with automatic translation features built into the driver’s work app or tablet.

“They can interact with their fleet manager in their own language, and the fleet manager can also interact back in their own language,” explained Notenboom. The same interface delivers active coaching: if a driver exceeds the speed limit, for example, an immediate warning appears. These software-based interventions help maintain standards without requiring constant direct supervision.

MEASURABLE GAINS AND EV TRANSITION

Notenboom agrees that customers understandably scrutinise the return on any additional technology cost. He reported that Webfleet users typically achieve efficiency improvements of up to 15 percent, though results depend heavily on the starting point. This ranges from fuel savings, faster turnaround, downtime reduction or improved driver behaviour, among others.

“If a company is already really good at saving fuel, then adding tools and driver coaching and technology might not change a lot. At the same time, even if it’s a small improvement, especially with the high fuel prices today, it could already translate to a lot of savings,” averred Notenboom.

The arrival of electric trucks introduces a fresh set of complexities. Research indicates that driver behaviour exerts an even greater influence on energy consumption in electric vehicles than in conventional combustion models. Smooth operation becomes critical to range, while decisions about when and where to charge add further layers of planning. Webfleet supports the transition by helping managers determine the right vehicle for each duty cycle.

“If you do long-distance transport, electric trucks are perhaps not the best option. But if you do inner-city deliveries, then electric trucks become an interesting option. And trying to find out where the optimum is, when to use Internal Combustion Engine-vehicles, where to use electric vehicles, that is also a part where we can help the fleet manager to make that decision,” he said.

On the technology package itself, every Webfleet customer receives the software platform. Hardware can be selected according to need, or in some cases, dispensed with entirely through the OEM.connect service (access vehicle data directly from OEMs via APIs), without installing extra hardware that draws data directly from the vehicle manufacturer.

“A number of customers are preferring to use OEM.connect. So that is a solution where we don’t install hardware but take the data directly from the OEM offerings,” he explained. On the other hand, where original-equipment data fall short, Webfleet’s own devices remain available.

PRIVACY, BENCHMARKING AND THE ROAD AHEAD

Growing data volumes inevitably raise questions of privacy and regulatory compliance. Webfleet adheres strictly to General Data Protection Regulation (GDPR) – a strict European Union (EU) law that protects information privacy and data rights for individuals in the EU and the European Economic Area (EEA) – requirements.

Certain categories of information can be processed only with explicit customer permission, and for benchmarking purposes, the company anonymises data so that individual vehicles or fleets cannot be identified.

A recent example is Webfleet’s Commercial Trip Monitor, which aggregates anonymised information across the entire customer base to generate comparative insights.

Looking three to five years ahead, Notenboom identified three principal challenges for the commercial-vehicle industry: the practical difficulties of electrification, the continuing shortage of drivers (with autonomous vehicles potentially addressing certain use cases over a longer horizon) and relentless competitive pressure to deliver higher quality service at lower cost.

He regards these same pressures as sources of opportunity for those able to convert them into advantage.

Interestingly, he shared that Webfleet itself continues to evaluate new markets beyond its established presence in Europe, South Africa, South America and Australia. Bridgestone’s ownership of the US-focused Azuga platform complements the portfolio, while Asia-Pacific, including India, remains under active review even if no immediate plans have been confirmed.

As Notenboom puts it, the goal is not to simply collect more information but to translate that information into clearer decisions that keep vehicles productive, drivers safer and costs under control – regardless of whether the powertrain is diesel or electric.

Yokohama Rubber, dotData Partner On Human-In-The-Loop AI Agent For Manufacturing R&D

Yokohama Rubber, dotData Partner On Human-In-The-Loop AI Agent For Manufacturing R&D

The Yokohama Rubber Co., Ltd. and dotData, Inc. have announced joint development an AI agent to help engineers form hypotheses, interpret findings and make decisions in manufacturing R&D. Before full deployment, the initiative will validate the agent's required capabilities and technical feasibility.

The solution combines technical documents such as design specifications and experimental reports with engineers' accumulated expertise and features extracted from measurement data via dotData's Signal Intelligence technology. It will provide insights tailored to each project's objectives, circumstances and constraints.

The agent is not meant to produce a single correct answer. Operating in a human-in-the-loop framework where engineers retain decision-making authority, it will present multiple possibilities, perspectives and risks to broaden thinking and support professional development.

Manufacturing R&D generates diverse data through experiments, simulations, production and evaluation. Developing hypotheses requires specialised knowledge and context. Since new technology R&D rarely has one predetermined answer, abductive reasoning plays a key role. AI can add value by using data and organisational knowledge to widen engineers' perspectives rather than replace judgment.

The agent will explore measurement and experimental data patterns beyond factors engineers previously identified, combining quantitative insights with design documents and expert knowledge to reveal difficult-to-spot relationships. It will offer input from materials, design, analysis, production and evaluation perspectives, challenge existing hypotheses and raise questions about alternative interpretations and conditions. Engineers will then test hypotheses and feed results back into further dialogue, guiding Signal Intelligence processes so non-specialists can explore data features as needed.

Yokohama Rubber has advanced HAICoLab since 2020, using dotData as a foundational technology in tyre design and rubber mixing. This joint development expands those efforts, with engineers interpreting and evaluating the agent's suggestions using their own expertise rather than accepting them unquestioningly. The companies aim to transform R&D processes while strengthening engineers' creativity and judgment, establishing a new model for human-AI collaboration in manufacturing R&D.

Motoji Fujita, Head of Research & Advanced Development Division, The Yokohama Rubber Co., Ltd., said, “Since 2020, we have conducted research and development under the HAICoLab framework, drawing on the complementary strengths of people and AI to create a collaborative environment. We believe AI agents will give engineers access to perspectives beyond their own experience and enable them to evaluate hypotheses from multiple angles. Through this development initiative, we aim to advance our R&D capabilities while supporting the continued growth of our engineers.”

Ryohei Fujimaki, CEO, dotData, Inc., said, “Success in manufacturing R&D depends heavily on an organisation’s ability to connect its proprietary data and knowledge with AI. The quantitative context generated from data through automated Signal Intelligence provides a foundation for AI agents to engage engineers in practical, data-driven discussions. Together with Yokohama Rubber, which has many years of experience in advanced data utilisation, we intend to establish standards for using AI in highly specialised business domains.”
