Status report on e-axle trailer development within GRVA, covering taxonomy, regulatory approach, and progress. The document presents use cases for electric axles in trailers of categories O2, O3, and O4, comparing simplified frameworks for O2 with fully integrated heavy vehicle frameworks for O3/O4. Progress includes updated taxonomy, ISO 11992 standardization work, and completed workshops. Step 2 adoption is targeted for January 2027, with Step 3 planning for O2 trailers to be clarified.
Proposal to amend para. 3.4.1. and para. 3.4.4. in Annex 8 to require manufacturers to address how the braking system strategy will not prejudice safe operation due to failures with other systems involved in achieving the function of the system, and insert new para. 4.5. in Annex 6 to require consideration of the effect of implausible wheel-speed information on anti-lock system operation in fault analysis. The proposal responds to a United Kingdom collision involving tyre failure and ABS activation that resulted in unsafe operation.
Proposal to insert a new para. 5.1.12. requiring that whenever an assessment of compliance to a requirement of this regulation is unachievable without reading internal signal(s) of an electronic system, the vehicle manufacturer shall provide instructions and tools to read signals on in-vehicle networks for the technical service to extract and interpret the signal(s), with this information appended to the test report.
