Intelligent transport systems — Motorway chauffeur systems (MCS) — Part 1: Framework and general requirements ISO/AWI 23792-1

Scope

Motorway Chauffeur Systems (MCS) perform level 3 automated driving [1] on limited access motorways with the presence of a fallback-ready user (FRU). MCS will be implemented in various forms capable of responding to different driving scenarios. This document describes a framework of MCS including system characteristics, system states/transition conditions, and system functions.
MCS is equipped with a basic set of functionalities to realize in-lane operation and may be equipped with additional functionalities such as lane changing.
This document specifies requirements of the basic set of functionalities and test procedures to verify these requirements. The requirements include vehicle operation to perform the entire dynamic driving task (DDT) [1] within the current lane of travel, to issue a request to intervene (RTI) [1] before disengaging, and to extend operation and temporarily continue to perform the DDT after issuing an RTI.
Requirements and test procedures for the additional functionalities are provided in the later documents of this set.
Means related to setting a destination and selecting a route to reach the destination are not in the scope of this document. This document applies to MCS installed in light vehicles [2].
