UN R167 Base text (01 series) · UNECE Regulation No. 167 (ECE R167) — Uniform Provisions Concerning the Approval of Motor Vehicles with Regard to Their Direct Vision.
UN R167 — 01 series of amendments
Changes from 00 series of amendments (supplement 1)
- What changed
- New paragraph 2.9.4. defines the “Subsection Frontal Visible Volume (SFVV)”. It is a portion of the assessment volume that includes the volume directly in front of the vehicle, between the offside and nearside planes.
- The SFVV is 26.1 per cent (Level 1) or 16.3 per cent (Level 2 and 3) of the result calculated (paragraphs 5.4.1. and 5.4.2.).
- New paragraphs 12. to 12.5. give transitional provisions with the dates 1 September 2031 and 1 September 2036.
- Why
- Design changes in levels 1, 2 and 3 could allow vehicles to pass the original frontal requirements without adequate direct vision directly in front.
- The SFVV proposal aims to keep VRUs directly in front of the vehicle out of a blind spot between direct and indirect vision.
- The specifications of the 3-D “H”-point machine have been updated and transferred from R.E.3 to M.R.1.
Q1What changed23 changes
New Subsection Frontal Visible Volume (paras. 2.9.4. and 5.4. to 5.4.2., Table 1)
New paragraph 2.9.4. defines the “Subsection Frontal Visible Volume (SFVV)”. It is a portion of the assessment volume that includes the volume directly in front of the vehicle, between the offside and nearside planes. Table 1 has a new row “Subsection Frontal Visible Volume” with the entry “See Paragraph 5.4”. Under new paragraph 5.4., the IAPD must be measured and the frontal volume calculated using the appropriate IAPD equation for the vehicle level being assessed. For Level 1 vehicles, the SFVV is 26.1 per cent of the result calculated (paragraph 5.4.1.). For Level 2 and 3 vehicles, the SFVV is 16.3 per cent of the result calculated (paragraph 5.4.2.).
High capacity vehicles and vehicles with competing objectives (para. 5.2.2.2.)
Paragraph 5.2.2.2. covers N3 vehicles in Level 3 that meet the design and construction criteria (a) to (d). These vehicles do not need to meet the required Front Visible Volume and Subsection Frontal Visible Volume. The words “and Subsection Frontal Visible Volume” are new in criterion (d).
Visible volume calculation in Annex 7 (paras. 5.1., 5.1.4. and 5.2.)
In Annex 7, paragraph 5.1. adds the SFVV to the views that must be constrained to only those volumes within the assessment zone. New paragraph 5.1.4. reads “The Subsection frontal visible volume”. Paragraph 5.2. now says that the total visible volume is the sum of the nearside, front and offside volumes. Before, it was the sum of the visible volumes to each side.
Transitional provisions (paras. 12. to 12.5.)
These paragraphs are for Contracting Parties applying this Regulation. From the official entry into force of the 01 series, no Contracting Party applying this Regulation may refuse to grant or accept 01 series type-approvals. Under paragraph 12.2., from 1 September 2031, Contracting Parties are not obliged to accept preceding-series type-approvals first issued after that date. Under paragraph 12.3., until 1 September 2036, they must accept preceding-series type-approvals first issued before 1 September 2031. Under paragraph 12.4., from 1 September 2036, they are not obliged to accept type-approvals issued to the preceding series. Under paragraph 12.5., notwithstanding paragraphs 12.2. and 12.4., they must continue to accept original-version approvals for vehicles not affected by the 01 series changes.
References to M.R.1 and R.E.3 (paras. 2.13. to 2.15. and footnotes)
Paragraphs 2.13. to 2.15. now refer to Addendum 6 of Mutual Resolution No. 1 (M.R.1). Before, they referred to the Consolidated Resolution on the Construction of Vehicles (R.E.3). A new footnote gives the M.R.1 document: ECE/TRANS/WP.29/1101/Amend.5. The footnote on the distinguishing numbers of the Contracting Parties to the 1958 Agreement now cites ECE/TRANS/WP.29/78/Rev. 7 instead of Rev.6. It also has a new web address.
Approval mark example (Annex 3)
The approval mark figure in Annex 3 is replaced. The example text now says “UN Regulation No. 167” instead of “UN Regulation No. [XXX]”. The text also says that the approval was granted to UN Regulation No. 167 as amended by the 01 series of amendments, instead of “in its original form”.
Figure 1 of Annex 4
Annex 4 has a new image for Figure 1, “Definition of the Assessment Volume, Based on a Category N3 Vehicle as an Example”.
Q2Why it changed
- Proposed by
- Experts from the United Kingdom of Great Britain and Northern Ireland and from the Netherlands
- Working party
- GRSG, 127th session (April 2024)
Reasons
Design changes in levels 1, 2 and 3 could allow vehicles to pass the original frontal requirements without adequate direct vision directly in front. The original volume score came from its correlation with the average of three VRU distances directly in front of the vehicle. The intent was to allow the driver to see these VRUs, and that they are not in a blind spot between direct and indirect vision.

“design changes could be made to vehicles in levels 1, 2 and 3, which could allow the vehicle to pass the frontal requirements defined in the original version, but without enabling adequate direct vision directly in front of the vehicle”
“This volume score was derived from the correlation between volumetric score and the average of three VRU distances directly in front of the vehicle.”
“the intent was to allow that these VRUs be seen by the driver, and not be in a blind spot between direct vision and indirect vision”
The revised proposal was to define a subsection frontal visible volume within the area of greatest risk. It aims to make sure that VRUs directly in front of the vehicle cannot be in a blind spot between direct and indirect vision.

The proposal is to update the references to the 3-D “H”-point measurement and calibration procedure, which is updated and moved from R.E.3 to M.R.1. A calibration procedure has also been added. Its purpose is consistent test results for the 3-D “H”-point machine across UN Regulations and UN Global Technical Regulations.

“A calibration procedure has also been added to ensure that the 3-D "H" point machine used for all testing in UN Regulations and UN Global Technical Regulations is consistent and provides consistent test results across Regulations.”
The footnote change is to correct the location of R.E.3 on the ECE/WP.29 website and to update to the latest amendment (Revision 7) of R.E.3.

Proposer's reason (informal document GRSG-127-07-Rev.1)
New paragraph 5.4. is to describe how the SFVV should be calculated to take account of the reduced volume for vehicles with narrower cab designs. The change to paragraph 5.2.2.2.(d) is to make clear that high capacity vehicles and vehicles with competing objectives need not meet the SFVV requirement.
