Proposal

• to clarify the requirements for the type approval of booster seats in the over 135 cm category,
• to update a reference with the new European Committee for Standardization (CEN) published EN 71-3:2019 on 10 April 2019,
• to delete a cut-and-paste error in Annex 6, Appendix 2 taken from UN R44 referring to ECRS as in the “restricted” category which does not exist in UN R129,
• to reconcile and consolidate various references to tolerances for the internal geometry assessment, and
• to exclude the head acceleration criterion in certain cases of contact when testing booster cushions with the larger Q-dummies, in particular the Q10, due to dummy rebound over the back of the test bench during a frontal test.

This document proposes amendments to the ESC prescribed test conditions in anticipation of future developments in steering systems.

Proposal for amendments to the requirements for Automatically Commanded Steering Functions (ACSF) of Category C, introducing specific provisions for the use of a lane change function with a two-step Human Machine Interface (HMI).

Proposal for amendments to the draft proposal concerning changes to the provisions introduced by the 02 series of amendments for remote-controlled parking (RCP).

Matrix illustrating a possible way that use of simulation, track, and real world testing might be applied to the various automated vehicle safety elements identified by WP.29 Contracting Parties.

Proposal concerning assessment of ACSF Category B1 lane keeping systems. Under Annex 8, proposal to delete the warning-to-deactivation cascade testing at high speed because the capability is already demonstrated under the low-speed test and the high-speed variation effectively requires a test track length of more than two kilometers. The proposal would also clarify paragraph 5.6.2.3.1. regarding the use of inputs other than lane markings where lane markings are not present.

Proposal for modifications to draft tolerances in the testing of ACSF B1 and C systems with regard to lane width, coordinate system, lateral acceleration, and overriding-force test.

The 01 series of amendments aims at increasing the performance requirements in the Car to Pedestrian
scenario by permitting only reduced maximum impact speed compared to the original version of this
Regulation. Thereby the same maximum impact speed is required for the Car to Pedestrian as for the
Car to Car scenario. However, in the original proposal (GRVA/2019/16), the permitted maximum impact speed for an N₁ vehicle erroneously corresponds to that of an M₁ vehicle. This proposal corrects the error.

Pursuant to discussions during the 9th session of the informal working group on AEBS for M₁/N₁, paragraphs 6.5.2. (pass conditions regarding “car-to-car moving” collision warning) and 6.6.2. (pass conditions regarding the collision warning in the Car to Pedestrian scenario) were deleted given that pass conditions were already defined by the general requirements. For consistency, this proposal would delete the pass conditions under the car-to-car stationary scenario.

Proposal to allow the use of a haptic signal as an alternative to the current requirement for an acoustic signal for the corrective steering function, provided the vehicle is equipped with a lane-departure warning system approved under UN R130. The proposal also introduces a requirement that the haptic warning must extend beyond the steering wheel (e.g., the signal would also include the driver’s seat) in order to address misuse (i.e., hands off the steering wheel use).

Proposal to correct editorial errors in the consolidated document WP29/2016/58 relating to GRRF-80-37, GRRF/2015/22 and GRRF-81-04-Rev.1 and to insert the word “tolerance” in para. 2.3.3.4.1.

Proposal to allow for the use of the maximum operable steering wheel angle of a steering system’s design in cases where the normalized angle as calculated under the regulation cannot meet the fixed values of the regulation (i.e., between 270 and 300 degrees). The intention is to enable approval of eventual systems (e.g., steer-by-wire) that may use low steering gear ratios.

Proposal to introduce provisions for a “two-step Human Machine Interface” in the requirements for Automatically Commanded Steering Functions (ACSF) of Category C lane-change functions.

Since an Automatically Commanded Steering Function (ACSF) of Category B is required to demonstrate compliance with regard to the warning cascade under testing at low speed, it is proposed to stop the high-speed test after the system has given the optical warning, meaning it has correctly detected the hands to be off the steering wheel.

Proposal to allow a corrective steering function to use haptic signals as an alternative to acoustic signals for M₂ and M₃ vehicles equipped with Lane Departure Warning System compliant with UN R130. The proposal would specify that the haptic warning may not be given solely via the steering wheel (e.g., provided in the driver’s seat).

Proposal to permit a function to cope with temporary driver inability to control the vehicle (e.g. caused by a health problem). The proposed emergency steering function of type (c) would warn and possibly revive the driver while automatically performing emergency lane change(s) with the aim to bring the vehicle to a standstill in an area with a low risk of collision (“target stop area” e.g. hard shoulder).

Proposal to introduce provisions contained in UN R98 and R113 but omitted from the superseding R149.

Proposal to introduce provisions into the cybersecurity recommendations paper and draft UN Regulation addressing access to in-vehicle data, functions and resources by independent aftermarket service providers.
