Sensitive sensors: TPMS for commercial vehicles

Measuring and controlling tyre pressure offers safety and efficiency when driving. From July 2024, tyre pressure monitoring systems (TPMS) will therefore also be mandatory for heavy commercial vehicles in the EU. They will then have to be standard equipment on newly registered lorries, vans, buses and motorhomes. The control sensors are not only intended to increase driving and road safety, but also to reduce pollutant emissions and fuel consumption.

There are direct and indirect measurement systems for checking tyre pressure. The tyre trade association BRV assumes that direct systems will predominantly be used for the TPMS obligation for commercial vehicles. They measure the air pressure via sensors in the tyres and provide a warning display on the dashboard in the event of deviations from the target value. However, TPMS are much more complex in the commercial vehicle sector than in passenger cars. For example, they must also function perfectly on trailers.

Manufacturers are developing suitable monitoring systems to fulfil the legal requirements of the TPMS obligation for commercial vehicles. Innovative sensor technology and data analysis enable precise monitoring of tyre pressure and early detection of potential problems. Complete systems offer real-time tyre monitoring for trailers. They effectively measure tyre pressure and temperature and provide alerts via text message or app in the event of deviations or punctures.

But how can lorry drivers and fleet operators benefit from the TPMS obligation? First of all, the early warning of pressure loss, over-inflation or other tyre problems ensures increased safety in traffic and for freight. Comprehensive monitoring systems also help to reduce downtime for fleets, save fuel in the long term and thus lower operating costs. Up-to-date software solutions are available for fleets of all sizes and ensure the continuous inspection and evaluation of tyres to optimise individual vehicles and overall performance.

However, the BRV association still sees many unanswered questions regarding the TPMS obligation when it comes to tyre servicing on trucks, trailers and buses. According to the association, over 90 percent of tyre servicing in the commercial vehicle segment is carried out by specialist tyre dealers.

There is therefore still a need for clarification on topics such as handling and storage or interfaces for data transmission for trailers. THE TIRE COLOGNE 2024 will focus on the challenges and opportunities associated with the TPMS obligation for the tyre industry. From 4 to 6 June, numerous new products will be presented at the international platform for the tyre and wheel industry. In addition, specialist presentations by experts will shed light on the new TPMS obligation for commercial vehicles. Shortly before its introduction, the trade fair will offer important impulses and practical tips for manufacturers and dealers.
