NBN ISO 19638:2021

This document contains the basic control strategy, minimum functionality requirements, basic driver
interface elements, minimum requirements for diagnostics and reaction to failure, and performance
test procedures for road boundary departure prevention systems (RBDPS). RBDPS is a driving safety
support system which acts on vehicles to prevent road departures. RBDPS is designed to reduce damage
and accidents arising from road boundary departures.
This document is intended to be applied to systems that predict road boundary departures and
maintain the vehicle within the road boundaries by both lateral acceleration control and longitudinal
deceleration control. RBDPS is intended to operate on roads (well-developed and standardized freeways
or highways) having solid lane markers. Roadwork zones or roads without visible road boundary
markers are not within the scope of this document. RBDPS is intended for light duty passenger vehicles
and heavy vehicles. RBDPS is not designed to operate continuously, but to operate automatically only
when possible road boundary departures are detected or predicted. However, the driver’s decision and
operation takes priority at all times.
