AHS Interoperability Protocol Mapping Matrix (ISO 15066, SAE J3016, MineStar™ v3.2)
The AHS Interoperability Protocol Mapping Matrix is a structured technical framework that aligns functional, safety, and communication requirements across three key standards—ISO 15066 (collaborative robot safety), SAE J3016 (automated driving levels), and MineStar™ v3.2 (Caterpillar’s proprietary autonomous mining system)—to enable seamless integration, validation, and certification of Autonomous Haulage Systems (AHS) in open-pit mining operations. It serves as a cross-walk tool for translating domain-specific terminology, data models, safety constraints, and operational boundaries into interoperable specifications. The matrix supports system architects, safety engineers, and OEMs in achieving regulatory compliance, vendor-agnostic interface design, and lifecycle-aligned verification.
📖 Overview
📑 Key Components
🎯 Applications
- ✓ Certification evidence generation for MSHA/ISO/IEC conformity assessments
- ✓ Inter-vendor AHS subsystem integration (e.g., third-party perception stack with MineStar™ control layer)
- ✓ Automated compliance checking during AHS software release validation cycles
📐 Key Formulas
Dynamic Separation Distance (DSD)
DSD = v² / (2 × a_max) + v × t_reaction + s_buffer
Calculates minimum safe distance between an autonomous haul truck and personnel/equipment, incorporating vehicle velocity (v), maximum deceleration (a_max), human/system reaction time (t_reaction), and safety buffer (s_buffer); derived from ISO 15066 Annex C and constrained by MineStar™ v3.2 braking model parameters.
ODD Coverage Ratio
OCR = (Area_ODD_MineStar ∩ Area_ODD_J3016_L4) / Area_ODD_J3016_L4
Quantifies the spatial and environmental overlap between MineStar™ v3.2’s validated operational envelope and the SAE J3016 Level 4 ODD definition; used to assess readiness for L4 deployment claims.
