Paper title: Regulatory requirements for electromechanical brakes Research and/or engineering questions / objective: The introduction of EMB (Electro Mechanical Brakes) in commercial vehicles to be registered in the EU is currently not allowed by the current Regulatory framework. The objective of this paper is to describe the activities which take place within the UNECE-WP29 expert to adapt the existing regulations (UN Regulation N. 13) to the technological development, as well as the challenges that need to be faced. Methodology: IDIADA, as a Technical Service for the type approval of vehicles, designated through different Type Approval Authorities has been part of the discussions of the regulatory expert groups for more than 25 years. In addition to that, IDIADA has a vast experience in the field of braking, both in the development and validation areas. This paper is a summary of the information being discussed in such forums, together with IDIADA own views based in our technical know-how. Results: As a result of the discussions being held in UNECE-WP209 subsidiary expert group GRVA, a proposal for a modification of UN Regulation N. 13, on braking for heavy vehicles, is expected to be released during 2023. This proposal will address two of the main challenges identified during the drafting phase: 1) Effect of ageing in EMB systems: It is expected that the usable performance of the system may be degraded in time, so appropriate requirements need to be developed. 2) Interaction between existing requirements and new ones: The introduction of a new set of requirements specific to EMB may have undesired side-effects on the requirements currently existing for air brakes. Limitations of this study: This paper addresses only the regulatory topics within UNECE environment. Other regions in the world use different sources for regulatory requirements and may not be aligned with the UNECE proposal. This paper is also based on discussions held at a theoretical level, so no test results will be included. What does the paper offer that is new in the field in comparison to others of the author: Even if the regulatory activity in the different forums has been intense during the last years, it has been mainly focused in the technologies linked to ADAS and highly automated vehicles, which has also been the main topic for papers related to the regulatory situation of braking systems. However, the technological evolution is not limited to such cases, and some developments are also present in more traditional areas. This paper cover one of those areas. Conclusion: Brake technology is constantly under evolution, and in some cases, such evolution may collide with some restrictions from the regulations. Such restrictions may impede the introduction in the market of innovative solutions which may be as safe as traditional technologies with enhanced functionalities. To avoid those burdens, it is essential that new technologies are raised for discussion to the relevant forums, in order to assess the need for new versions of the regulations. This paper aims at the dissemination of such information, so as to make visible the relevance of the work from the regulatory forums.
