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 (c) 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).

Proposal to allow a corrective steering function to use haptic signals as an alternative to acoustic signals for M₂ and M₃ 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).

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.

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.”

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.

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.

Amendments submitted from GRVA.

Proposal to introduce provisions for a “two-step Human Machine Interface” in the requirements for Automatically Commanded Steering Functions (ACSF) of Category C lane-change functions.

Presentation on Tesla experience with hands-on lane-keeping and automated lane-change systems, especially with regard to lateral acceleration and distance limits under UN R79.

Text approved by GRVA consolidating input from stakeholders and agreed changes to the original proposal (GRVA/2019/19) for submission to WP.29 at its March 2020 session. The proposal amends the draft text (GRVA/2019/9) submitted to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:

• inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
• sampling rate of at least 100 Hz for dynamic testing,
• specification of filters and cut-off frequency for determination of lateral acceleration,
• option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

Proposal to allow for higher lateral acceleration limits for Automatically Commanded Steering Functions (ACSF) in executing lane changes. The proposal modifies acceleration limits in the original proposal (GRVA/2019/27) and focuses on the timing for lane changes (e.g., 15-second total duration).

Proposal to modify lateral acceleration values for Automatically Commanded Steering Functions (ACSF) of Category B1 (e.g., SAE L2 lane-keeping) and to allow the vehicle under test to change speeds in order to meet maximum lateral acceleration values when navigating curves.

Proposal to allow the use of a haptic signal as an alternative to the current requirement for an acoustic signal for the corrective steering function, provided the vehicle is equipped with a lane-departure warning system approved under UN R130. The proposal also introduces a requirement that the haptic warning must extend beyond the steering wheel (e.g., the signal would also include the driver’s seat) in order to address misuse (i.e., hands off the steering wheel use).

Changes to the proposal to update and clarify Annex 6 on requirements for documentation, fault strategy and verification of the safety of electronic systems and complex electronic vehicle control systems related to vehicle steering.

Updated remote-controlled maneuvering proposal with editorial Improvements, clarification that the actuator of the function is to be included as part of the assessment along with the hardware and software on the vehicle, and to add requirements on the security of the connection between the remote-control device and the vehicle.

Proposal for modifications to draft tolerances in the testing of ACSF B1 and C systems with regard to lane width, coordinate system, lateral acceleration, and overriding-force test.

Proposal concerning assessment of ACSF Category B1 lane keeping systems. Under Annex 8, proposal to delete the warning-to-deactivation cascade testing at high speed because the capability is already demonstrated under the low-speed test and the high-speed variation effectively requires a test track length of more than two kilometers. The proposal would also clarify paragraph 5.6.2.3.1. regarding the use of inputs other than lane markings where lane markings are not present.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems.

Proposal to supplement paragraph 5.6.4.6.7. with additional requirements regarding lane-change driver actions that should allow for a more intuitive user experience while limiting a significant risk of mode confusion.

Proposal to allow for higher lateral acceleration limits for Automatically Commanded Steering Functions (ACSF) in executing lane changes.

Discussion of lateral acceleration values for Automatically Commanded Steering Functions (ACSF) of Category B1 (e.g., SAE L2 lane-keeping) and proposal to allow the vehicle under test to change speeds in order to meet maximum lateral acceleration values when navigating curves.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems.

Proposal to update and clarify Annex 6 on requirements for documentation, fault strategy and verification of the safety of electronic systems and complex electronic vehicle control systems related to vehicle steering. The assessment particularly addresses driver assistance and automated steering.

1. inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
2. sampling rate of at least 100 Hz for dynamic testing,
3. specification of filters and cut-off frequency for determination of lateral acceleration,
4. option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

Proposal to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.

Outcomes from the discussion of the proposal from France to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.

Request to extend the ACSF mandate a further 12 months.
