ISO DIS 21717

Description / Abstract: 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 Partially Automated In-Lane Driving Systems, in the following referred to as PADS.

PADS is fundamentally intended to provide partially automated driving by longitudinal and lateral control of equipped vehicles while travelling on roads where non-motorized vehicles and pedestrians are prohibited. Free-flowing as well as congested traffic conditions could be addressed by PADS. The functionality of the longitudinal control will be standardized referring to ISO 15622 Adaptive Cruise Control systems. The intention of the lateral control is to keep the vehicle in the lane and not to perform lane changes.

The responsibility for safe operation of the vehicle always remains with the driver. The driver shall have means to override the PADS at any time. Automated driving systems of level 3 or higher (as defined in SAE J3016:2016) are not in the scope. The standard shall apply to passenger cars, commercial vehicles and buses.
