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
can 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 are equipped with a basic set of functionalities to perform in-lane operation
and can also 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.
This document describes one specific form of system engagement. Other forms are possible.
These other system engagement forms, especially those provided in combination with
other driving automation system features, are not within the scope of this document.
Requirements and test procedures for the additional functionalities are provided in
other parts of the ISO 23792 series.
