Draft procedure for lane-guidance assistance systems (category B1 ACSF).

Proposal for new paragraphs in the draft ACSF amendment concerning provisions to ensure the system capacity to monitor and adapt to road conditions and the environment surrounding the vehicle in order to ensure safe behavior and minimize risks. This proposal replaces paragraphs in the previous document ACSF-06-28 based on the discussions of the 6th meeting and document ACSF-06-18 by OICA and CLEPA.

Proposal of a research project to assist the ACSF informal group in the development of provisions for the approval of lane-keeping and lane-change assistance and other ACSF systems.

Proposal of provisions regarding the use of a type approval numbering system that includes information on the ACSF capabilities and software version.

The draft amendment to enable automated steering systems for use at speeds above 10 km/h includes provisions for a minimal risk maneuver (MRM) in the event that the driver fails to respond to a demand to assume control of the vehicle. This document proposes provisions for the automatic activation of hazard warning lights under an MRM scenario.

Breakdown of the requirements of the draft consolidated amendment (ACSF-06-28) for each category of ACSF.

Table of ACSF categories as defined by functions and requirements of the draft amendment to UN R79.

Proposal for amendments to document ACSF-07-02.

Consideration of the borderline in distinguishing between corrective steering functions and automatically commanded steering functions towards defining requirements for the approval of automated steering systems.

Proposal towards defining corrective steering functions as a distinct function apart from automatically commanded steering functions.

The ACSF draft requires that the “system shall be designed so that excessive intervention of steering control (e.g. an excessive steering torque) is suppressed to ensure the steering operability by the driver and to avoid unexpected vehicle behavior….” OICA proposes objective thresholds for ensuring driver ability to safely override the system.

OICA input on definition of corrective steering and automatically commanded steering functions.

Report as approved by the group delegates.

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.

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

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.

Latest version of the amendment proposed in document GRRF/2016/45 as Option 3 and under discussion within the ACSF informal group

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.

Proposal for an “Emergency Steering Function” to automatically assist drivers in avoiding an impending collision with an obstacle or other vehicle.

Proposal to include under the complex electronics annex of UN R79, if only as an interim measure, provisions for the approval of automated systems that bring a vehicle safely to a stop in the event of driver incapacitation.

Proposals to clarify and refine provisions in the draft corrective steering function amendment to UN R79 (document GRRF-82-12/Rev.3).
