Summary of UNECE activities related to automated vehicle systems and driving.

Comments on the draft amendment to UN R79 addressing automated steering as it stood at the end of the third ACSF informal group session. This document also raises links to rear vision (UN R46), AEBS (UN R131), and park assist systems.

Presentation proposing a requirement for defensive braking on vehicles equipped with ACSF because automated steering may result in driver inattention and therefore require compensating environment monitoring and automatic braking. This type of “protective braking” is viewed as a different order of braking than AEBS given that the principle involves maintaining of distances and avoiding accidents at speed rather than as an emergency or abrupt braking.
