Proposal to amend the consolidated draft amendment to UN R79 to introduce technical requirements for Corrective Steering Functions and Level B1 ACSF under UN R79 (document GRRF/2016/45).

Updated version of the draft amendment to introduce provisions for corrective steering and Category B1 ACSF into UN R79 based upon discussions held during the afternoon GRRF session of 21 September.

Proposed changes to the draft amendments to UN R79 concerning ACSF B1 systems. The proposed new wording for the triggering condition of the warning (“any front tyre of the vehicle is crossing the lane marking”) is technically more specific than the original (“the vehicle is going to leave the lane”). The use of a haptic signal as an alternative to the acoustic signal achieves the goal pursued by Germany. This proposal is consistent with the warning strategy of AEBS specified in UN R131. In the case of M2 M3 N2 N3 vehicle categories, it is proposed to take as a base the requirements specified in UN R130 LDWS regulation, which achieves the goal.

UN R79 amendment proposal to introduce provisions for “corrective steering functions” as a separate category of steering system from automatically commanded steering functions (ACSF). Corrective Steering Function (CSF) means the control function within an electronic control system whereby, for a limited duration, changes to the steering angle of one or more wheels may result from the automatic evaluation of signals initiated on-board the vehicle.

FIA comments on data privacy provisions under UN Regulations including remarks concerning the work of the informal groups on automated driving (ITS/AD), automatic emergency calls systems (AECS), and automatically commanded steering functions (ACSF). The presentation covers issues such as protection of personal data, aggregation of data to protect individual identities, protection against unauthorized access (hacking), and prohibition against data use for purposes other than those specifically intended by a regulation. FIA proposes the deletion of data storage (DSSA) provisions under the draft texts for ACSF.

Proposal to amend “option 4” as presented in the proposal introduce technical requirements for Corrective Steering Functions under UN R79 (document GRRF/2016/45). Option 4 for consideration by GRRF proposes to amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1. The proposal includes:

• Clarification of Corrective steering function (CSF) incl. defining of new requirements;
• Establishment of new categories for automatically commanded steering function (ACSF): Categories A, B1, B2, C, D and E;
• Wording for requirements of Category A (incl. remote parking RCP), and Category B1.

Proposal of amendments to the draft proposal concerning technical requirements for automated steering functions operating at speeds up to 10 km/h and for corrective steering functions under UN R79.

Proposal, consolidating document GRRF-82-08 with the proposed test procedures, revising “option 4” as presented in the proposal introduce technical requirements for Corrective Steering Functions under UN R79 (document GRRF/2016/45). Option 4 proposes to amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1. The proposal includes:

• Clarification of Corrective steering function (CSF) incl. defining of new requirements;
• Establishment of new categories for automatically commanded steering function (ACSF): Categories A, B1, B2, C, D and E;
• Wording for requirements of Category A (incl. remote parking RCP), and Category B1.

During its 8th meeting (Stockholm), the ACSF informal group decided that all functions to “assist the avoidance of a collision” would be excluded from the definition of “Corrective Steering Function”. ACSF decided to establish a new definition for “Emergency Steering Functions (ESF)” with specific requirements. The intention was to draft this definition during a second phase effort through which requirements for ACSF categories beyond B1 will be established. In order to enable the approval of ESF systems critical to road safety, OICA has prepared this proposal for an ESF definition and simple requirements based upon provisions for Complex Electronics (CEL) in Annex 6. A footnote has also been added to define the specific conditions for the approval of these systems, until uniform provisions are defined by the ACSF informal group.

In order to enhance the safety of B1 corrective steering functions (by reducing the probability of driver over-reliance and misunderstanding of system limitations), OICA proposes a minimum value of 0.8 m/s² for maximum lateral acceleration in place of the draft 1 m/s² for the speed range between 100-130 km/h for M1 and N1 vehicles. OICA believes that this would ensure that a system is capable under all conditions of generating the required minimum acceleration.

Industry comment in support of “Option 4” in document GRRF/2016/45, the proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation.

VDA research on warning times and proposing a 30s threshold at lower speeds.

French proposal based upon the German proposal (ACSF-08-03)

Proposal to reduce the maximum delay for warning a driver of prolonged ‘hands-off driving’ as a function of vehicle speed. The current calculation is based upon 30 seconds (i.e., t(s) = 30(s) * 130/V, where V is the speed of the vehicle in km/h at the time when the system has detected that the driver is no longer holding the steering control). Korea proposes 15 seconds. Additionally t would not be permitted to be greater than 180 seconds.

Proposal on CAT A based on document ACSF-07-07.

Hyperlink address corrections.

Proposal to introduce technical requirements for Corrective Steering Functions (lane departure prevention, lane-keeping assistance (LKAS), steering angle correction, etc.) as defined in the regulation. The proposal offers four options to ensure appropriate approvals of LKAS and related CSF systems until such time as more precise requirements can be defined:

• Option 1 and option 2: Not to grant any type approvals for corrective steering functions until detailed technical requirements for CSF are incorporated into this Regulation.
• Option 3: Amend the definition of CSF as proposed in this document.
• Option 4: Amend the definition of corrective steering functions and to include technical requirements for LKAS as an ASCF of Category B1 as proposed in this document.

Changes proposed by Germany to the draft ACSF amendment (document ACSF-05-16)

Copy of document GRRF-81-14: Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

Working draft from the ACSF informal group to enable the approval of automated steering systems intended to operate at speeds greater than 10 km/h presented for information and discussion at the 81st GRRF session.

Consolidated draft for the approval of automated steering systems pursuant to the discussions and decisions of the 5th ACSF informal group session (January 2016).

Document GRRF/2016/20 proposes to remove certain design restrictions that impede the application of new technologies, especially related to trailer power steering systems and the use of energy from the towing vehicle, including specification of the connector through which electrical energy is supplied in the proposal. Although this proposal was approved in principle at the 80th GRRF session, it was agreed that the proposal would be reviewed at the 81st GRRF to define an open value [X] in paragraph 2.1.1. of Annex 5. It has subsequently been concluded that this change to paragraph 2.1.1. is not needed. Therefore, this proposal removes the change to the paragraph from GRRF/2016/20.

Presentation on French government views on the approval of automated steering at speeds above 10 km/h under UN Regulation No. 79. The principle recommendation is to restrict amendments to UN R79 to lateral vehicle control as speeds above 10 km/h while setting other work on more advanced capabilities (longitudinal + latitudinal, lane change, passing, etc.) for future separate regulations.

Test procedure application for advanced systems of category D depending upon the steering configuration per category B (B1:hands-on with detection system steering, B2: hands-off enabled steering).

Proposed changes to the working draft text ACSF-04-20.

OICA presentation on approaches and trade-offs in handling driver availability for transitions between automated vehicle system and human driver.

OICA and CLEPA note that the current work on ACSF does not address class O vehicles (trailers) and therefore leaves unsettled the issue of heavy-duty commercial vehicles. The two groups signal that the informal group must coordinate with the GRRF to ensure that trailers are eventually incorporated in the ACSF approval procedures under UN R79.

Schematic flow of events and responses for automatically commanded steering functions, including transition demands and fall-back on minimum risk maneuvers by the system.

Table of requirements for automatically commanded steering function capabilities (e.g., hazard warning activation, driver alerts, minimum risk maneuvers, etc.) according the ACSF category.

Presentation on paragraph 5.6.1.4 of the draft amendment to UN R79 intended to enable the approval of automatically controlled steering functions at speeds above 10 km/h. This paragraph concerns transitions between the human driver and the automated steering system.
