J presented the document LKAS-02-05, proposing amendments to GRRF-78-14 for introduction of ACSF provsions into UN R79.

3. (b) | Explanation of GRRF-78-14

The European Commission welcomed LKAS-02-05 as automatic driving is a subject that is currently discussed at EU level, yet found that the subject goes a bit beyond the usual Type Approval regulations.
CLEPA also welcomed the document
OICA presented a short PPT presentation on lane changing maneuvre on highways. The driver must voluntarily activate the system.
OICA supported CLEPA, and supported opening UN R79 to this technology.
NL found the document a good starting point but found necessary to get more precise requirements.
J pointed out that the requirements can be different according to the systems. The expert recalled that the aim is to maintain road safety via an “if fitted” regulation. He acknowledged that this proposal mainly provides design requirements.

The Chair, as S representative, found it a good start: lane keeping and lane changing system.
J found lane changing assist a very important system and was keen to put the necessary resources to provide the relevant requirements, primarily focusing on highway situation. The expert wondered whether such system, in particular for emergency lane change, are covered by the Vienna Convention.
OICA made the comparison with ESP, where the driver must provide an input, but the system intervenes only when the driver cannot anymore master the situation. Concerning the text, OICA found the structure improved compared to the document presented at GRRF-78, e.g. regarding the modified definition of Automatically Commanded Steering Function
The secretary pointed out that there is a need to open the regulation for permitting the Industry to start designing the technology.
CLEPA found the proposal wise as restricted to certain use cases, and the expert was of the opinion that the regulation could evolve in the future with the evolution of the technology.
OICA informed that regins do not have the limitation of 10km/h and that there is a need that the UN region can take profit of the new technologies. The expert voiced that UNECE should not be left behind, but should rather open up to such new technologies, with appropriate requirements to ensure safety.
