The deadline for the submission of official working documents for this GRVA session is 15 November 2019.

6. (a) Automatically Commanded Steering Functions

GRVA will review three revised proposals tabled by the expert from the European Association for Electromobility (AVERE) aimed at clarifying technical provisions regarding ACSF of Category B1 and C.

GRVA-05-08/Rev.2 | UN R79 : Proposal for amendments to Supplement to the 03 series The proposed text combines the proposed changes in GRVA/2020/8 (proposal for a maximum time of 15 seconds for a lane change) with the adopted changes in GRVA/2019/24.
GRVA-05-09/Rev.1 | UN R79 : Proposal for amendment to Supplement to the 03 series Proposal combining the proposed changes of GRVA/2020/9 with the previously adopted changes in GRVA/2019/24.
GRVA-05-09/Rev.2 | UN R79: Proposal for amendment to Supplement to the 03 series
GRVA-05-09/Rev.3 | UN R79: Proposal for amendment to Supplement to the 03 series Proposal to clarify conditions for automatic deactivation of the direction indicator pursuant to a lane change maneuver.
GRVA-05-24 | UN R79: Proposal for amendments to document GRVA/2020/7 Amendments to refine the proposal to increase maximum lateral acceleration limit values up to 4 m/s² for speeds up to 80 km/h for M1/[N1] category vehicles, provided there is no heavy rain and ambient air temperatures are above 4°C. The proposal sets the speed at 60 kph while specifying a linear reduction of lateral acceleration to a maximum 3 m/s² at 80 kph.
GRVA-05-24/Rev.1 | UN R79: Proposal for amendments to document GRVA/2020/7
GRVA-05-52 | UN R79: Evidence regarding the proposed amendments to ACSF of Category C
GRVA-05-53 | UN R79: Proposal for amendments to the 03 series of amendments ACSF systems in use were brought to market based on exemption approvals in the EU. These systems show a good and safe performance. Approvals according to UN R79/03 would force modifications to currently used systems without any apparent safety benefit. The current formula for the calculation of s<sub>critical</sub> does not take the dynamic behaviour of the vehicles into account, therefore requires gaps that under some traffic conditions don’t usually occur. Since there are different ways of addressing the dynamic behaviour of the vehicles with regard to the original formula, this proposal would allow the manufacturer to specify its own formula provided the safety principle is maintained.
GRVA-05-57 | UN R79: Proposal for amendment to the 03 series of amendments Proposal to allow ACSF-B lateral acceleration above the maximum limit value in cases where the lane position cannot be maintained by the vehicle (for example, on a tightening curve).
GRVA-05-58 | UN R79: Proposal for amendments to GRVA-05-09-Rev.1
GRVA-05-59 | UN R79: Proposal for amendments to GRVA-05-24
GRVA/2020/7 | UN R79: Proposal for a Supplement to the 03 series of amendments Proposal to increase maximum lateral acceleration limit values up to 4m/s² for speeds up to 80 km/h for M1/[N1] category vehicles, provided there is no heavy rain and ambient air temperatures are above 4°C.
GRVA/2020/8 | UN R79: Proposal for a Supplement to the 03 series of amendments Proposal for a maximum time of up to 15 seconds for an Automatically Commanded Steering Function (ACSF) of Category C to start a lane change.
GRVA/2020/9 | UN R79: Proposal for a Supplement to the 03 series of amendments Proposal to stipulate that "Automatic deactivation by the system of the direction indicator is required only if the lane change manoeuvre is initiated automatically, or if the direction indicator control is not fully engaged (latched position) during the lane change manoeuvre."

GRVA may wish to review a document prepared by the experts from the International Organization of Motor Vehicle Manufacturers (OICA) and the European Association of Automotive Suppliers (CLEPA), proposing to amendments to the provisions on ACSF of Category B1 in UN Regulation No. 79.

GRVA-05-30 | UN R79: Proposal for amendments Proposal for provisions concerning:<ul><li>B1 lane centering</li><li>ACSF activation conditions</li><li>Driver override</li><li>Clarification of ACSF standby-mode</li><li>Clarification of “ready-to-intervene"</li><li>Indication to the driver in case of suppression</li><li>Clarification of suppression criteria</li><li>Sensor test before activation.</li></ul>
GRVA/2020/10 | UN R79: Proposal for Supplements to the 02 and 03 series of amendments Since an Automatically Commanded Steering Function (ACSF) of Category B is required to demonstrate compliance with regard to the warning cascade under testing at low speed, it is proposed to stop the high-speed test after the system has given the optical warning, meaning it has correctly detected the hands to be off the steering wheel.

GRVA may wish to consider other submissions, if any.

GRVA-05-50 | UN R79: Proposal for amendments to the 03 series of amendments The proposal to clarify that enabling the system under the test procedure is only necessary in cases where the system is not already in the enabled state.
GRVA-05-63 | UN R79: Proposal for ESF (c) - Emergency Assistance Presentation on the safety benefit of automated emergency steering in case of confirmed driver inability to perform the driving task.
6. (b) Steering equipment

GRVA agreed to review a revised proposal amending the warning provisions related to Corrective Steering Functions, tabled by the experts from OICA and CLEPA.

GRVA/2020/11 | UN R79: Proposal for Supplements to the 02 and the 03 series of amendments Proposal to allow a corrective steering function to use haptic signals as an alternative to acoustic signals for M<sub>2</sub> and M<sub>3</sub> vehicles equipped with Lane Departure Warning System compliant with UN R130. The proposal would specify that the haptic warning may not be given solely via the steering wheel (e.g., provided in the driver’s seat).

GRVA may wish to review a proposal for amendments to the Emergency Steering Function provisions in UN Regulation No. 79, tabled by the experts from CLEPA and OICA.

GRVA/2020/16 | UN R79: Proposal for a Supplement to the 03 series of amendments Proposal to permit a function to cope with temporary driver inability to control the vehicle (e.g. caused by a health problem). The proposed emergency steering function of type <notextile>(c)</notextile> would warn and possibly revive the driver while automatically performing emergency lane change(s) with the aim to bring the vehicle to a standstill in an area with a low risk of collision (“target stop area” e.g. hard shoulder).
6. (c) Remote Control Manoeuvring

GRVA may wish to continue considerations on Remote Control Manoeuvring provisions.

GRVA-05-47 | Remote-controlled parking: Alternative human-machine interface (HMI) Video demonstration of RCP system.
