Proposal to align the text of UN R152 with recent updates to UN R131.

Proposal to clarify that the occurrence flag to be stored according to paragraph 8.2.1. (n) are linked to the abortion of the lane change manoeuvre rather than to the procedure and to make related clarifications for consistency.

Proposal to prevent activation of an Automatically Commanded Steering Function of Category C for a minimum of [10] seconds after the system has verified that the road is of a valid type when merging into a roadway. The activation delay of [10] seconds prevents the system from being used during merging from the motorway’s acceleration lane. According to the proposal, the merging process during the acceleration phase is not fully suitable for an automated lane change due to, among other things, the vehicle dynamics and the limited space available. In addition, the delay shifts the driver’s notification of the automatic activation of the ACSF-C system to a time when the vehicle is already in a stable driving condition on the motorway and the driver’s attentional resources are more available to receive the notification. A manual activation of the system remains possible.

Proposal for amendments to Annex 18 regarding special requirements for electronic control systems and for related transitional provisions for its entry into force.

Proposal for the following amendments:

1. Paragraphs 6.1.1. and 6.1.2.: In the case of category L vehicles application, the same brake lining assemblies could be fitted across a variety of applications. For example, the same brake pads/shoes could be fitted both on vehicle with single disc and on vehicle with double discs. Moreover, the same brake pads/shoes could be fitted both on front application and on rear application vehicle. Since there are too many cases or variables and it’s impossible to have a package based on the axle set for category L vehicles, the proposal of amendment is meant to consider the caliper set/drum set, instead of the axle set.
2. Paragraph 6.1.3.4.: Packaging of brake pads/drums has a limited dimension and it’s impossible to report in the packaging all applications approved, because there is no space available. In addition, should all applications approved be reported in the packaging, the updating of each packaging every time there is a new application available in the market would be needed. This is not feasible and it represents a risk to have a product with no updated information for the final consumer. For these reasons, the proposal aims to allow, as option, to report the approved vehicles/brakes/axle information through digital format (e.g. QR code, website) leading at least to a general catalogue. Moreover, using digital elements, it’s also possible to have a green solution and having a less environmental impact. The modification proposal is optional, and not exclusively for category L vehicles, but it is meant for every type of motor vehicles even if the major criticalities are with category L vehicles because their packaging is smaller than brake pads/drums of passenger car.
3. Paragraph 6.1.4.: The current requirement asks to have fitting instructions inside the packaging with at least an ECE language supplemented by the corresponding text of the language of the country where the product is sold. It means two options:
   • To have a specific fitting instruction for each country where the component is sold; or
   • To have a unique fitting instruction with all languages.
   Option 1 is not feasible from management and logistic point of view. Option 2 is not feasible because there is limit space available in the packaging: For example, to be sold in EU (that recognize UN R90), it’s needed to have all official 24 languages of the EU in a unique fitting instruction paper, but there are applications where the packaging is too small to contain the fitting instruction paper. For these reasons, the proposal of modification asks the possibility to have these fitting instructions also through digital format only (e.g. QR code, internet website, …). Moreover, using digital elements/formats, it’s possible to reduce the environmental impact because the instructions become paperless. The modification proposal is optional, and not exclusively for category L vehicles, but it is meant for every type of motor vehicle even though the major criticalities are with category L vehicles because their packaging is smaller than brake pads/drums of passenger cars.

Proposal to permit the use of virtual testing as an alternative methodology to the physical tests. This approach requires the preliminary assessment of the methodology to be used.

Draft proposal to introduce provisions for the type approval of vehicles with electro-mechanical braking (EMB) systems.

Proposal with tracked changes revising the earlier proposal for a new UN Regulation on Urban Emergency Braking Systems.

Proposal to introduce provisions into the new UN Regulation on commercial vehicle driver direct vision (tentatively UN R167 pursuant to its adoption at the November 2022 WP.29 session). The proposal is based on a previous proposal to establish a new UN Regulation on Urban Emergency Braking Systems (UEBS).

Proposal to introduce the option of using a QR code (or other type of digital data carrier) to replace the paper installation instructions physically included in the packaging.

Proposal to introduce the option of using a QR code (or other type of digital data carrier) to replace the paper installation instructions physically included in the packaging.

Proposal to clarify a logical cascade of actions regarding activation of ACSF B1 and C and the indication on when the vehicle has entered an eligible road based on the following:

1. When the same means is used by the driver to simultaneously activate the Automatically Commanded Steering Function of Category B1 (ACSF B1) and of Category C (ACSF C), both functions switch to standby mode when the vehicle enters an ACSF C eligible road. But if the road is non-eligible to ACSF C, then only the ACSF B1 is activated.
2. With the current text of the regulation, once the vehicle moves to an ACSF C eligible road, the driver must operate again the means to activate the ACSF C. This second deliberate action is confusing for the driver since it makes the manipulation more complex. The current wording discourages most drivers from using this assistance function.
3. The proposed wording permits the following, logical, cascade of actions:
   1. The driver has done a deliberate action to activate ACSF B1 and ACSF C (on a non-eligible road); then
   2. He drives into an eligible road, and is clearly informed thereof; then
   3. He initiates a lane change procedure by activating e.g. the direction indicator.
4. This amendment further clarifies the requirement on the indication of when the vehicle enters an eligible road. It gives some examples of the type of indication to be given to the driver, e.g. additional popup or blinking indication, without being design restrictive.
5. A dedicated status indication of an ACSF C off-mode is by nature already different from the standby or active indication. Therefore, the driver is already sufficiently informed on a potential status change.
