Proposal for amendment to Regulation No. 79

Reference Number: GRRF/2016/45

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.

Consolidated draft amendment to UN R79 with regard to corrective steering functions (CSF), including test requirements

Reference Number: ACSF-08-11/Rev.1

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.
