Proposal to define and require countermeasures to ensure that a driver remains available to assume control of a vehicle from an automated lane-keeping/steering system as conditions warrant. This document proposes definitions for a “driver attention recognition [system/function]” and/or a “driver attention confirmation [system/function]”.

Proposals to clarify that references to “other road users” includes pedestrians and large animals and, with respect to ensuring the driver’s availability to assume control of the vehicle, a time frequency limit for driver monitoring systems based upon the time required to travel a distance of 1500 m with an upper limit of 180 seconds (i.e., the time required to travel 1500 m at 30 km/h).

Proposal for amendments to the provisions on Data Storage Systems for ACSF under the draft amendment to enable the use of automated steering systems at higher speeds under UN R79.

New text proposal from the group of Contracting Parties for the definition of the Corrective steering function (CSF) to be included in Regulation 79. The proposal shifts the provision on a sound warning during CSF engagement to the requirements section (from the definitions section).

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.

The Netherlands and Sweden note strongly urging consideration of system safety and software assessment issues before proceeding with approval procedures for Category B2 and/or E ACSF, including a discussion of the role, if any, of ISO 26262 under Annex 6.
