The first vehicle manufacturers have been successfully certified for idem TPMS and telematics in accordance with R.156!
The implementation of OTA updates for trailer control units within the context of UN ECE R156 is often portrayed as impossible.
In fact, however, the regulation does not impose a blanket exclusion –
on the contrary: it defines a clear framework for secure and traceable software updates.
What is crucial here:
• A robust and validated rollback strategy
• A stable and secure power supply for updates and recovery
• Proof that functional vehicle safety remains guaranteed at all times
• A reliable communication channel to the user
idem’s approach offers solutions for precisely these requirements. This means that the benefits of OTA updates can also be utilised in a R.156-compliant manner for telematics units and TPMS control units.
