Scope: It stipulates the principles of automatic driving classification for shield machines, the elements of automatic driving classification, the requirements for implementing automatic driving, and provides a table showing the relationship between automatic driving classification levels and key elements, as well as a table describing the characteristics of automatic driving levels for shield machines. Main technical content: This document specifies the standards for automatic driving classification levels for shield machines, and is applicable to the automatic driving classification of various types of earth pressure balance shield machines and sludge balance shield machines. It clarifies the principles of automatic driving classification levels for shield machines from L0 to L4; proposes five automatic driving judgment elements, including situational constraints, autonomous decision-making, task execution, safety supervision, and human intervention; determines the technical conditions for automatic driving classification levels; stipulates the requirements for implementing automatic driving and the technical requirements for shield machines; and forms a table showing the relationship between automatic driving classification levels and key elements, as well as a table describing the characteristics of automatic driving levels for shield machines.
