Text prepared by the GRVA secretary, based on GRVA/2023/2 as adopted by GRVA during the 15th session, to highlight amendments to the approval number and marking provisions with regard to the series of amendments.

Proposal to add the text, "In case that saturation of the front tyres happens before the above calculated magnitude angle, this angle may be used as the final steering amplitude, but only if this angle is greater or equal to 6.5 A.” based on the following justification:

1. Reaching fixed amplitude, i.e., fixed steering wheel angular speed due to given 0.7 Hz sine frequency, needs much more torque with quick steering gear ratio systems than with slow steering gear ratio systems, and produces much more wheel steer.
2. Car behavior (yaw rate, lateral acceleration and thus trajectory) is similar for all amplitudes above approx. 7 to 8 A (i.e., more than 7 times the steering wheel angle corresponding to 0.3 g), because front tires are saturated. More steer of the tires doesn’t provide more lateral force, so yaw rate and lateral acceleration don’t increase. Continuing to increase steering wheel amplitude after front tire saturation doesn’t give more information.
3. There might appear in the future some vehicles which have significantly low steering gear ratio (i.e., quick steering characteristics) and may need too much steering wheel torque to achieve the 270 degrees sine amplitude at 0.7 Hz (not reachable by conventional steering robots), then jeopardizing the easy approval of future beneficial steering equipment e.g. steering-by-wire systems.

Revised proposal prepared by the GRVA secretary pursuant to discussions during the 15th session 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 justification:

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.
6. Regarding paragraph 5.6.4.2.3.: While entering the eligible road, the driver may be distracted or annoyed by this “prominent” indication. His attention resources shall be totally available during this phase. So the system would switch automatically to standby mode when fulfilling these two conditions: reaching an eligible and regular lane of travel. This second condition may be fulfilled for example by implementing a suitable time delay or by a direct verification of the lane of travel. These criteria should be explained, agreed between the technical service and the vehicle manufacturer.

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

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 from the informal group on on Cyber Security and OTA issues for amendments:

1. To reflect updates and the most current version of relevant standards, notably ISO/SAE 21434:2021 and ISO/PAS 5112, and
2. To update the text in line with Supplement 1 to UN R155 (WP.29/2022/54).

Proposal from the informal working group on Cyber Security and OTA issues (CS/OTA) to update the text:

1. Use of “802.11p” to refer to V2X communications is out of date: 802.11p is properly referred to as 802.11-OCB and other direct communication methods are in use. “V2X” is the preferred term.
2. Platooning is a niche V2X operation and not widely used: The proposal suggests to use more mainstream examples such as cooperative awareness or manoeuvre coordination.
