Document Title: UN R140: Proposal to amend provisions for steering amplitude

Document Reference Number: GRVA-15-55

Description:

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:

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.
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.
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.

Document Title: UN R79: Proposal to amend GRVA/2023/6

Document Reference Number: GRVA-15-54

Description:

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:

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.
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.
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.
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.
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.
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.

76th GRRF session (17-21 Feb 2014)

35. The expert from OICA introduced ECE/TRANS/WP.29/GRRF/2014/13, as amended by GRRF-76-39, proposing the wording of a draft regulation on the Tyre installation for M₁ vehicles. The proposal received some comments and GRRF agreed to revisit this item on the basis of a revised proposal that the expert from OICA volunteered to prepare.

75th GRRF session (17-19 Sep 2013)

41. The expert from OICA introduced GRRF-75-20 proposing a first draft for a new UN Regulation on tyre installation and requested guidance. The expert from EC proposed to extend the scope of the proposal to vehicle categories M, N and O to harmonize the proposal with the corresponding Commission Regulation No. 458/2011. He announced that the EC would consider applying this Regulation and replacing the corresponding Commission Regulation. The expert from the Russian Federation proposed to refer explicitly to UN Regulations Nos. 30, 54 and 117 in the draft. GRRF invited the experts to send comments to the OICA expert not later than 29 November 2013. GRRF agreed to resume consideration of this proposal at its next session on the basis of a revised document that the expert from OICA volunteered to prepare.

78th GRRF session (16-19 Sep 2014)

47. The expert from OICA presented GRRF-78-28 amending ECE/TRANS/WP.29/GRRF/2014/13 on the tyre installation for M1 vehicles. The proposal received some comments. GRRF agreed to revisit this item at its next session on the basis of a revised proposal by OICA.

79th GRRF session (16-20 Feb 2015)

44. The expert from OICA presented GRRF-79-08, superseding ECE/TRANS/WP.29/GRRF/2014/13 on the tyre installation for M1 vehicles. The proposal received some editorial comments. GRRF agreed to revisit this item at its September 2015 session on the basis of a revised proposal by OICA.

80th GRRF session (15-18 Sep 2015)

59. In absence of new proposals tabled by the expert from OICA, the Chair recalled the purpose of ECE/TRANS/WP.29/GRRF/2014/13 amended by GRRF-79-08 proposing a draft Regulation on tyre installation and that the expert from OICA agreed to table a revised proposal addressing the comments received. The expert from Japan tabled GRRF-80-26 addressing concerns expressed at the seventy-ninth session of GRRF. The expert from EC kindly informed GRRF that the lack of harmonization between the draft UN Regulation and the existing EC Regulation 458/2011 might prevent the EU from applying this regulation. The expert from OICA submitted GRRF-80-36 at the end of the session for review and comments by the experts of GRRF in view of the submission of an official document for the February 2016 session of GRRF.
