The Tyre Pressure Monitoring System (TPMS) tech, despite its huge safety benefit, is still seen as a premium feature in most mass-market passenger vehicle segment and two-wheelers in India. Aurangabad-based component supplier Varroc’s Indirect TPMS with over 90 percent accuracy aims to make smart inroads. Tier 1 automotive supplier Varroc is looking to harness the data from GPS sensor and Anti-Lock Braking System (ABS) sensors to provide tyre pressure information to two-wheelers and four-wheelers. 

The company is looking to make smart gains through Indirect Tyre Pressure Monitoring Systems (ITPMS), which rely on existing sensors in a vehicle to generate the information without compromising on quality and time-lag.

Fritz Abraham, Chief Technology Officer, Varroc, told Tyre Trends that “the direct TPMS uses pressure sensors at the air inlet of each tyre and communicates the information to the vehicle dashboard using wireless communication or through complex harness. This is not only expensive but also require heavy maintenance. If there exists a solution that can use the existing sensors and provide the information of tyre pressure, it is the ‘Indirect/Intelligent Tyre Pressure Monitoring System’. This system provides information of the tyre pressure without the need of a pressure sensor.”

The radius of the tyre changes with respect to air pressure and hence the linear displacement per one rotation of tyre changes with respect to the pressure. The linear displacement can also be measured using GPS by calculating the rotational speed of the wheel and radius of the tyre.

The ITPMS solution simply put is a software stack that can be integrated with Varroc’s cluster and telematics solutions. The machine learning (ML) software analyses various parameters set by the company to provide tyre pressure reading to the user. Since it does not require any additional TPMS hardware, it is substantially cheaper compared to solutions using battery-based sensors.

“The ITPMS exploits the deviations in linear displacement with respect to wheel rotations and predicts the tyre pressure. This relation is not straightforward; it is a complex method to derive the mathematical equations. Hence, ML techniques are used to quantify the relation,” said Abraham.

The ITPMS primarily requires a GPS sensor (telematics data) and ABS, which is integrated during the vehicle assembly level. Varroc states that OEMs will be able to provide access to the tyre pressure on any HMI (Human-Machine Interface) device like the vehicle instrument cluster, vehicle telematics and connectivity app, among others, to easily provide the information of the tyre pressure.

Varroc had initially initiated the development of the ITPMS specifically for two-wheeler applications. The company mounted a GPS device on a two-wheeler equipped with ABS. It collected the data during vehicle operation across varied scenarios, including differing tyre pressures, diverse road conditions and various weather conditions such as sunny and rainy days.

“This data was then post-processed and analysed using data science and machine learning techniques to develop a model that accurately captures the relationship between tyre pressure, wheel speed and the speed as measured by the GPS. This model forms the foundation for understanding and monitoring tyre pressure indirectly using available data points from the vehicle’s operation,” he shared.

Demand scenario for TPMS

It is no secret that while TPMS technology has been around for more than a couple of decades, its adoption in India still remains a very small percentage. In India, most TPMS solutions available in the OE as well as aftermarket are Direct TPMS.

They are said to have their own set of challenges, such as its reliability due to varying temperatures, environmental and climatic conditions. Then there are the challenges associated with wireless communications. Sensor battery issues and cost too are deterrent factors.

On the other hand, the small percentage of vehicles that utilise existing ITPMS categorise the tyre pressure in broad classifications (low pressure or high pressure). They do not provide precise measurements, which limits their adoption and effectiveness in ensuring optimal tyre performance and safety.

However, Varroc already has developed the ITPMS to provide basic information (low or high); now it is in advanced stages of development to provide precise tyre pressure information with over 90 percent accuracy.  While the company has been tight-lipped about the introduction of the solution in the market, Varroc is said to be in discussions with its clients to bring it to the market soon.

Abraham further shared, “The primary reason for the limited adoption of TPMS is cost. Premium segment vehicles often include TPMS as a standard feature due to the higher price range, making it more feasible to absorb the associated costs. In contrast, aftermarket TPMS solutions are generally expensive and demand ongoing maintenance, which can be a deterrent for many vehicle owners.  Additionally, there is a general lack of awareness regarding the importance of maintaining optimal tyre pressure. Many drivers may not fully understand the safety, performance and fuel efficiency benefits of consistent tyre pressure monitoring, further impacting the adoption rate of TPMS systems.”

As per the company, the ITPMS comes with self-learning feature and is designed with 80 percent cold tyre pressure threshold and tested per AIS 154. The threshold can be further optimised and customised as per the requirement of the customer.
