Download in .pdf format Download in .docx format

Proposal to expand the scope to include N category vehicles and to apply the minimum performance for service braking systems (5 m/s²) as required in the 11 series of amendments to UN Regulation No. 13, for vehicles of the Categories M2, M3, N2 and N3. The overall objective of the former Informal Working Group (IWG) on Automatically Commanded Steering Function (ACSF) was to develop technical requirements for Automated Lane Keeping Systems (ALKS). The initial limitation to passenger cars (M1 category vehicles) was agreed in order to deliver within the given timeline. After having successfully accomplished the work for the system in a first step, the automotive industry has now reviewed and examined the existing requirements under the premise of including all vehicle categories M and N.
