With the R141 legislation now in full effect, it mandates that all trailers across Europe are equipped with a Tyre Pressure Control System.
Alongside a Tyre Pressure Monitoring System, many fleets are now choosing to advance their system further by installing a Tyre Pressure Refill System (TPRS) or a Central Tyre Inflation System (CTIS), to comply with the new standards.
Understanding the R141 Legislation
The R141 regulation came into full effect in July of this year as a way to standardise tyre pressure control across the European Union, ensuring that all trailers are equipped with systems that monitor and maintain optimal tyre pressure. The R141 legislation aims to deliver the following advantages:
•Enhanced Safety: proper tyre pressure reduces the risk of blowouts and improves vehicle handling.
•Improved Fuel Efficiency: under-inflated tyres increase rolling resistance, leading to higher fuel consumption. Maintaining optimal tyre pressure can result in significant fuel savings.
•Reduced Tyre Wear: correct tyre pressure ensures even tyre wear, extending the lifespan of tyres and reducing replacement costs.
•Environmental Benefits: efficient fuel consumption and longer tyre life contribute to lower carbon emissions and reduced environmental waste.
Fleets are now faced with the choice of opting for a standard or advanced management system. A functioning Standard TPMS that can monitor tyre pressure in real-time is what every trailer must have. Another option, however, is the Advanced TPMS or CTIS, which, when integrated, can enhance their compliance and operational efficiencies. These systems automatically refill tyres and maintain them at the optimal pressure.
Celerity DRS offering
In partnership with US market leaders, Pressure Systems International, Celerity DRS offers the market both advanced (TPRS) and standard (TPMS) solutions and are the only European provider homologated with all major axle manufacturers.
The Tyre Pressure Refill System (TPRS) from PSI is used globally and has demonstrated its reliability on more than two million trailers. In order to meet all requirements of R141, PSI and CDRS have redesigned the original TPRS control unit to allow for greater connectivity. The updated version features a new, streamlined design and enhanced functionality all while maintaining the system’s high quality.
The new functions include electronic pressure control, which allows more precision, as well as system status communicated by CANbus to the dashboard of the truck, showing the tyre status without an additional in-truck display unit.
In addition to TPRS, Celerity DRS have recently added the TPMS system ‘TireView’ to their range of products.
“Our primary goal was to provide a functional and cost-effective TPMS that meets European requirements,” said Celerity DRS General Manager, Andre Gerken. “Through close cooperation with PSI, we have successfully adapted their proven TireView system to fulfil all of these requirements.”
The TireView system is a simple design and consists only of an ECU, sensors and, if necessary, a repeater. The ECU is powered by the EBS and allows monitoring of up to 38 sensors. Alongside pressure, the sensors are also reading the temperature.
All of this information is sent to the dashboard of the truck via CANbus or can be integrated into a telematic system, such as their own ‘TireView live’ system. Both solutions, TPRS or TPMS, allow companies to fulfil their R141 obligations and improve the efficiency and safety of their fleet
“TPRS include automated inflation capabilities, which not only ensure tyres are consistently maintained at the correct pressure, but also remove manual intervention,” Gerken said. “By leveraging these advanced systems, fleets can not only meet regulatory requirements, but also gain substantial operational advantages, including increased tyre longevity, optimised performance, and significant cost savings. Embracing these technological innovations will position fleets at the forefront of safety and efficiency in the evolving landscape of transportation.”
Celerity DRS will be showcasing their latest advancements in tyre pressure monitoring at IAA Transportation 2024 in hall 27, stand A23
