Proposal to ensure that endurance braking is assessed in the context of the Type II-A test based on the maximum mass of the vehicle or vehicle combination.

Proposal to resolve the problem of decreasing trailer brake performance caused by brake pads and linings “falling asleep”.

Proposal to introduce provisions for the approval braking systems for e-trailers and Electric Regenerative Braking (ERB) in towed vehicles of Category O.

Proposal to enable the type approval of a park lock device as an alternative to, or in combination with the friction parking braking to hold the vehicle.

Proposal to enable live recording of brake demand values during Periodic Technical Inspections (PTI),

Proposal to permit the type approval of a park lock device as an alternative to the friction parking brake(s).

Proposal to resolve an inconsistency in wording across the series with regard to the parking brake performance requirement.

Proposal to address loss of trailer friction braking efficiency due to increased use of robust endurance braking systems and electrification of trucks. The number of trucks with strong endurance braking systems and increasing electrification of vehicles with more efficient energy recuperating systems reduces the use of friction brakes. As a result, brake pads and linings in some commercial vehicles do not reach a temperature that is needed for the development of optimum brake performance. In particular in trailers, a loss of brake force develops due to brake pads and linings losing effectiveness – they “fall asleep” and need to be replaced although they are not worn out.

Proposal for amendments to the draft provisions on e-trailers.

Proposal to update the regulation in line with technical advances and the emergence of a new type of braking system that employs stored electrical energy for both the control transmission and the energy transmission and to clarify the application of the Type II test.

Proposal to clarify the need to apply, when relevant, the Type II test as required by Annex 4 under paragraph 1.8.2.5 (b) in Annex 15 for alternative brake lining purposes.

Documents as discussed and updated during the 15th FADS task force session.

Proposal to keep a reliable test of heavy-duty vehicle brakes in PTI regardless of technology without creating new obligations to vehicle owners or managers, to ensure braking efficiency is subject to PTI test, and to read only proposal with no cybersecurity threats. Reference braking forces shall be declared at type approval per axle and made available for roadworthiness activities. Wheel brake demand values shall be available live on the vehicle. Either a digital procedure reading wheel brake demand or actuator values through OBD using universal diagnostic tools, or an analogic procedure measuring voltage or power supplied to brake actuators at manufacturer-designated points, shall be used to assess braking forces against reference values using current roller brake testers.

Proposal to allow periodical technical inspection testing and verification of heavy-duty braking systems without burdening the vehicle
owners/managers.

Proposal to clarify the need to apply, when relevant, the Type II test as required by Annex 4 under paragraph 1.8.2.5 (b) in Annex 15 for alternative brake lining purposes.

Proposal to clarify provisions concerning the type-IIA test and the test mass of vehicles authorized to tow trailer(s).
