Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79.

Supporting presentation on the proposal to insert a new sub-paragraph 5.6.1.1.4.1 to exempt ACSF Category A functions intended solely to support low-speed vehicle controllability manoeuvres in off-road environments from the obstacle detection requirements of paragraph 5.6.1.1.4, provided the function operates only until 5 km/h with 1 km/h tolerance, is activated deliberately by the driver in off-road environments only, requires the driver to be in the driver’s seat with safety belt fastened, and allows the driver to retain control and override or deactivate the system at any time.

Proposal to modify the specified maximum remote controlled parking operating range from 6 m to 15 m. Large markets including Canada, USA, and China do not regulate maximum remote controlled parking operating range. Remote controlled parking systems exceeding 6 m operating range are already offered in the field. Radio wave-based ranging is inherently inaccurate due to complicated and varying electromagnetic environment in garage and changing orientation of remote device, requiring safety margin integration into product design, which reduces effective usable range below 6 m maximum. Extended range remote controlled parking systems have been used in the field for several years without negative feedback or identified safety threats.

Proposal for amendments to the requirements for Automatically Commanded Steering Functions (ACSF) of Category C, introducing specific provisions for the use of a lane change function with a two-step Human Machine Interface (HMI).

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.

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 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).

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 clarify that a continuation of support by a Category B1 ACSF after its boundary conditions have been exceeded may not be possible under conditions as outlined in the manufacturer’s safety concept.

Proposal to

1. Align lane-centering provisions with principles applied to UN R157 (ALKS)
2. Permit Category C ACSF to remain in stand-by during temporary roadway transitions
3. Clarify overriding provision (para. 5.6.4.3) reference to stand-by mode
4. Introduce a tolerance factor for “critical situation” lane changes
5. clarification to test conditions
6. Align direction indicator deactivation under a pass conditions with previously adopted provisions.

Proposal to introduce provisions for truck/trailer data transmission for Category C ACSF.

Proposal to clarify the provisions for ACSF Cat. A “Remote Controlled Parking (RCP)” for vehicle combinations. The current definition for RCP S_RCPmax sets a maximum limit of 6m distance to the motor vehicle, which is insufficient in situations where the operation is supervised by the driver located behind the vehicle combination.

Proposal to align UN R79 and UN R157 with UN R152 (AEBS for M1 and N1) regarding the conditions for automatic re-instatement of a system at the “initiation of each engine start / run cycle”.

Proposal to clarify the provisions for full power steering systems such as steer by wire systems (based on discussions held under the EBSIG interest group addressing electro-mechanical braking systems under UN R13 and 13-H).

Proposal to clarify provisions concerning the conditions for automatic re-instatement of the system at the “initiation of each engine start / run cycle”.

Proposal to clarify provisions for full power steering systems such as steer-by-wire systems.

Proposal for amendments to the 05 series of UN R79 to enable the type approval of ADS vehicles, including those without manual controls.

Proposal to insert a new sub-paragraph 5.6.1.1.4.1 to establish exemptions for Automatically Commanded Steering Function Category A functions designed for off-road low-speed vehicle recovery manoeuvres, and amend para. 5.6.1.2.7 to increase the specified maximum Remote-Control Parking operating range from 6 m to 15 m.

Proposal first presented to the ACSF informal group for a type-approval mechanism to control for updates to software dependent systems.

Proposed changes to align RxSWIN provisions with the RxSWIN template adopted through WP.29-197-06, remove the proposed requirement to comply with UN R156/01 or later from R157 and R171, remove amendments to UN R155 as decided by the IWG CS/OTA, apply the RxSWIN amendments also to earlier series of amendments in R13, R13-H, R79, R131, R152, R157, and R171, update references to the latest version of R.E.3, ECE/TRANS/WP.29/78/Rev.8, in earlier series, and correct paragraph references and improve structure in R89, R139, R140, R155, R156, and R171.
