According to a research report, by 2026, TMPS penetration will up to 79% and 25.26 million units be installed from the installation 16.49 million units in 2019. China will be the main growth driver for the TPMS segment

Growing legal compulsions and focus on safety, comfort and fuel efficiency will drive demand for tyre pressure monitoring systems (TPMS), says Agneta Ronceret, EMEA TPMS Manager for OEM, truck and industrial markets at ATEQ.

ATEQ is the leader in supplying a wide range of TPMS activation tools for tyre workshops and assembly lines at auto manufacturing plants across the globe. ATEQ’s TPMS range covers simple TPMS triggering tools, TPMS reset tools, complete TPMS relearn tools and more advanced TPMS diagnostic and programming tools, which can either be used autonomously or in combination with an OEM scan tool.  The company’s TPMS decoding tool can trigger or activate sensors, receive TPMS sensor information and send the TPMS sensor information to the vehicle’s ECU. The TPMS sensor information collected by the TPMS decoding tool includes the pressure within the tyre, the temperature of the TPMS sensor, the wheel rotating speed, the TPMS sensor unique ID, the battery status of the TPMS sensor, and more.

TMPS legal requirement was introduced in 2008 after Firestone recalled more than 6.5 million vehicles due to tread separations. As per the first version of the Tread Act, from 2008, all passenger vehicles and light trucks with GVWR of 10,000 lbs and less should be equipped with a TPMS. Europe, in 2012, too formulated EU TPMS regulations to make to TPMS compulsory in all new passenger vehicles from November 2014.

As of now the European Union, the United States, South Korea and China have already made TPMS mandatory in the vehicles, while other countries such as Japan, Indonesia, India, the Philippines and Malaysia are in the process to introduce TMPS legislation in the respective markets soon.

“Many countries and auto companies have a vision of zero road accidents or casualties. Followed by the US and Europe, other major markets, such as China, which is the largest automotive market, have also made TMPS mandatory. Multiple companies are also voluntarily implementing TPMS in their vehicles to optimize safety, mileage, and comfort. These trends will drive the growth for the TMPS market,” Ronceret told Tyre Trends.

According to a research report, by 2026, TMPS penetration will up to 79% and 25.26 million units be installed from the installation 16.49 million units in 2019. China will be the main growth driver for the TPMS segment.

Ronceret was appointed to the position last year to tap growing demands of the OEM, Truck and Industrial segments for Europe, Middle East, Africa and Australia and New Zealand regions. “There are lots of new activities that are happening in the OEM, Truck and Industrial segments. We have different objects for different segments. As the market grows and technology changes, ATEQ will bring innovations to increase our presence in the OEM, Truck and Industrial markets,” Ronceret said.

Air inflation

Tyres are the only component of the vehicle that touches the road. From safety and comfort and mileage largely depend on the air inflation in the tyres. Generally, a tyre naturally loses 0.2 atmospheres (2.9 PSI) every three months, and a slow puncture precedes 85% of all tyre blasts. Inappropriate tyre cause to the instability of the vehicle, and less mileage and the total life of tyres.

According to a study, around 30% of underinflated tyres increase fuel consumption by 5%. NHTSA, US EPA and US GAO studies say that in the US alone the overall deterioration in fuel economy due to underinflated tyres is 3.3% and the average annual wasted fuel is between 1.2 and 2.8 billion gallons. Over 2 billion gallons of fuel are wasted in Europe annually due to underinflation, as per Bridgestone Europe. At the same time, tyre life reduces by 50% if it runs at 20% under-inflation.

A TPMS updates the driver on air pressure conditions of the tyres. Inside the tyre, behind the valve, sensors measure pressure and temperature all the time, and as soon as the tyre pressure starts to drop, the sensors begin omitting alert signals to the ECU. 

There are two types of TPMS sensors, direct and indirect. Using the TMPS inside the wheel, the direct TPMS sensor, mounted on the wheels or tyre, reports accurate data on tyre pressure to the ECU. The direct TPMS systems are used European, the US and Asian markets.

Based on the ABS sensors, the in-direct TPMS system analyses the acceleration of the tyre and if the dimension of the tyre changes, so will the acceleration of the tyres. The ABS sensors notice the changes in the dimension of tyres and indicate the same. “The direct the TPMS is more precise as it gives you real-time data on pressure, whereas the ABS sensors only give you an indication,” said Ronceret.

Today the company operates in the three TMPS segments- Workshop Tools, Truck TPMS and Industrial TPMS.

ATEQ workshop tools are used in OEM garages and vehicle workshops for activating, diagnosing, programming and fitting TPMS valves and sensors. The workshop tools also help to replace the broken sensors in the tyre and even programme the sensors. “There are companies that make universal sensors, so ATEQ TPMS tools help to write programmes for those sensors. The tools also help to pair the sensors with the ECU,” explained Ronceret.

Revenue-wise, the workshop tool is segment is the largest business for ATEQ.  “For the workshop tools, we have to be evolutive. A bigger challenge for the company is to have the compatible tools for the existing and future vehicles,” said Ronceret.

The industrial tools, fitted at one place, are used in the vehicle production line to check whether tyres are accurately inflated before mounting on the vehicles.

ATEQ has a comprehensive range of TPMS control equipment for small to large manufacturing. On the assembly lines, its TPMS test antennas are key for the installation of TPMS sensors and the pairing of TPMS sensors with the vehicle’s ECU. The company supplies customized TPMS tools test TPMS sensors on OEM light vehicle and truck production lines, as well as wheel and tyre assembly lines, laboratories and test benches all over the world.

In trucks, a 10 PSI, less air pressure increases, rolling resistance by 2%, while industry surveys show that consistent proper tyre inflation in truck tyres would increase fleet wear by 17%.  Today, understanding the importance of the right tyre pressure, now many fleet companies have installed TPMS systems to improve the total cost of ownership. For the European truck industry, the company provides the ATEQ VT TRUCK tool, which checks tyre pressure and sensor batteries to prevent under-inflation and reduce vehicle downtime due to tyre blowouts. The tool is compatible with most European truck and bus TPMS sensors and benefits from a continually growing vehicle coverage, thanks to frequent database updates,

The company gets data from all OEMs to make sure it is updated with the times. “We have all data since we work with OEMs since the integration at the production lines to the workshops. It is also essential of them to we can serve them all the times.” The company maintains confidentiality on the secured data. The tools deal with the information collected from sensors but do not store them.

Hankook Tire revealed the Design Innovation 2020 project, which defines a vision for the future driving and innovation in mobility.

Launched in 2012, the Design Innovation is Hankook’s R&D project held every two years, in collaboration with one of the world’s leading design universities.

Under the theme ‘Urban Reshaping’, professors and students from the Department of Industrial Design at the University of Cincinnati in the U.S. focused on the transformation of cities geared by reconfiguring mobility as part of living spaces rather than stand-alone purpose in the future with augmented automation infrastructure and cutting-edge technologies such as eco-friendly technology, autonomous driving and Artificial Intelligence (AI).

Throughout the project, modular platform of mobility concept named ‘Hankook Platform System (HPS)-Cell’ was proposed with tyre representing the root of mobility. It is applied with ‘Hankook Electric Mobility Technology (H.E.M.)’ which represents Hankook’s passion for future technological breakthroughs. Then a scenario was created which distinguishes mobility as a moving platform and its function as a pod (space), clearly elaborating that tire indeed sits at the center of the mobility.

The tyre of HPS-Cell embodied an airless tyres’ double-layered unit-cell structure to acquire complex rigidity. It is a concept tyre that uses sensor technology to not only identify tire treads and road conditions in real time, but also to respond to wear-out risks and change tread patterns according to the road condition utilizing variable wheels and optimized infrastructure.

The scenario was brought into reality in a concept film and a mock-up. The productions suggest that in 2040 urban population will be able to use this mobility platform combined with pods of various forms to each meet a specific purpose. The modular platform can also be combined with commercial pods such as urban farming to maximize the scalability and efficiency of movement within smart cities of future generation.

The unveiled productions will be exhibited at various global channels and will represent Hankook’s capabilities in design innovation globally.

Jimmy Kwon, Vice President of Hankook Tire Brand Lab said, “Hankook Tire is incorporating new ideas with our cutting-edge technology to explore design concepts for the next generation, as Hankook believes creativity is the first step towards bringing the imagination into the reality. We are more than excited to present this year’s works as they speak for the essence of the future mobility that Hankook envisions.”

TATNEFT has announced the development of a new line of ATV tyres called the KAMA Quadro ATM. The first model has been made in 25x8-12 standard size at its Nizhnekamskshina factory in Russia.

The ATV tyre, which is developed by Kama Scientific and Technical Center, has been specially designed for off-road driving, providing excellent cross-country ability in mud and snow. The tyre’s special rubber composition ensures high reliability and traction performance.

The first batch of tyres will go for pilot testing to TATNEFT subdivisions that operate off-road special vehicles.

The KAMA Quadro ATM range is currently being developed in nine tyre sizes covering 12 to 14 inches diameter, with nine more sizes coming up over the next year. The factory will begin production of 25x10 tyres for the rear axle in addition to the already manufactured  25x8 tyres intended for the front axle.

The KAMA Quadro ATM will meet the needs of the TATNEFT Group’s all-terrain vehicles used in oil fields and will also be used to equip Russian ATV manufacturers and the secondary market. (TT)

Kumho tyres have outperformed 52 rival manufacturers to ace the Auto Bild magazine’s summer tyre test with its ECSTA HS51 high-performance pattern tyre.

The annual test is among the most comprehensive of its type, the results of which are regarded as highly significant by both the European tyre trade and its consumers.

Conducted on both wet and dry surfaces, it left Kumho in a fighting third place overall. However, while the further qualifications caused the two leaders to slide down the order, 33 of the 53 entries were eliminated by the initial braking test. Kumho’s highly competitive and consistent scores in almost every discipline ultimately left it as the sole test winner.

 Awarding the ECSTA HS51 their coveted ‘Exemplary’ badge, the Auto Bild testers commended it for its precise steering response, secure wet grip, well-balanced handling, short braking distance, low wear rate and affordable price.

Unlike some tyre tests, where the products are supplied by the manufacturers, those for the Auto Bild ones are covertly purchased by the magazine from regular retail outlets. The chosen size was 205/55R16, the direct fitment for the bulk of Volkswagen Golfs and Audi A3s etc., and therefore arguably the one most common within the European car market.

UK purchasers currently have the choice of 35 sizes of ECSTA HS51 for wheels of 15 to 18 inches in diameter. The qualification round of the test was carried out at ATP (Automotive Testing Papenburg) in Germany and the other tests were performed at the IDIADA facility in Spain. 

Thus, our newly developed "Tire Leap AI Analysis" utilises advanced AI-based analysis technology to analyse (for example) electron microscope imagery of tyre rubber compounds in order to achieve high-precision analysis that far exceeds human capabilities, thereby making it possible to derive accurate estimates of rubber properties from structural data found in this imagery.

Specifically, it is a technology that estimates rubber properties precise from combining data on the individual raw materials contained in a rubber compound with data on its internal structure. In the future, we will continue to develop this technology and develop technology to estimate the future rubber properties from electron microscope imagery of unused rubber.

■ Technology to Precisely Estimate Rubber Properties Based on Structures & Materials

Tire Leap AI Analysis utilises an AI-based image analysis system to analyse the internal structures of rubber in images captured by an electron microscope in order to infer information about the properties of the rubber based on its structural data (i.e. the results of image analysis). By combining this structural data with data about the materials that make up rubber compounds, this technology is then able to derive information about the physical properties of rubber with a high degree of precision.

■ Technology to Detect Changes in the Internal Structures of Rubber After Use & Estimate Resulting Changes in Rubber Properties

By comparing images of a tyre that has never been used (i.e. that is brand new) with images of a tyre that has been used (i.e. after wear over time), this AI-based image analysis system can determine where changes have occurred in the internal structures of the tyre’s rubber and then estimate the physical properties of the rubber in the areas that have undergone these changes. The practical application of this technology will facilitate the design of new rubber compounds that are less prone to performance degradation due to wear and tear, thus contributing to the development and advancement of Performance Sustaining Technology.

Dr. Miki Haseyama, Hokkaido University: We have developed a new AI technology that is able to estimate the extent of changes in the structures based on analysis of images of the internal structures of rubber. As compiling data for this kind of machine learning would otherwise be extremely time-consuming, one of the main merits of this new technology is the fact that this AI does not require prior field data from structural changes in rubber for machine learning. Rather, this AI uses deep learning to learn about the properties of new rubber (i.e. prior to undergoing structural changes) and then estimates the extent of changes in the structure by analysing how data from old rubber (i.e. after undergoing structural changes) compares to the data that it has previously learned about new data. This approach to machine learning allows the AI to automatically detect various types of changes in the structures of rubber.

Kiyoshige Muraoka, Senior Executive Officer, Sumitomo Rubber Industries: We have been working jointly with Hokkaido University to further advance the development of AI technology that can understand how the internal structures of tyre rubber change through use. We have already put this new technology to use in the development of our latest “ENASAVE NEXT III” fuel-efficient tyres, which not only achieve the highest possible “AAA-a” rating for fuel efficiency and wet grip performance (under Japan’s tyre labelling system), but also reduce changes in tyre performance that occur over time as a result of use by half. Moving forward, we will continue to advance our Tire Leap AI Analysis technology to find and analyse slight variations in the internal structures of rubber that human senses and knowhow have been unable to detect so that we can then use the resulting knowledge to develop new technologies that further enhance tyre performance and ensure that this high performance lasts longer. In this way, we will accelerate research and development toward producing high-performance tyres that provide greater safety and peace of mind with the aim of contributing to the realisation of a sustainable mobility society for future generations.
