Automatically Commanded Steering Functions (ACSF)
Reports to GRVA

UN Regulation No. 79 contains provisions for the use of an “automatically commanded steering function” (i.e., automated steering) that restricts use to speeds up to 10 km/h. In light of automated vehicle systems (such as lane keeping assistance) that propose automated steering control at higher speeds, including on highways, the ACSF informal working group was formed to consider amending UN R79 to enable the approval of such higher speed automated steering systems.

In addition to the core system capabilities and performance provisions, the group expects to consider malfunction warning requirements and system testing under periodic technical inspections.
