Integrated Execution Specification Design and Engineering Verification for ICV Simulation Testing

Aiming at the problems in the engineering implementation of intelligent connected vehicle (ICV) simulation testing, including inconsistent requirement parsing, manual-dependent use case generation, poor cross-platform adaptability, low batch regression efficiency, and low scene reproduction consistency, this paper proposes an integrated execution specification for simulation testing covering intelligent requirement parsing, parameterized use case construction, constraint screening, instruction mapping and closed-loop execution. Taking the unified test semantics as the core, this specification establishes a multi-dimensional parameterized model and realizes pre-verification of use case validity through regulatory constraints, physical constraints and safety constraints. The standardized instruction mapping engine is adopted to convert test semantics into executable instructions of simulation platforms automatically. Engineering verification results show that the specification can greatly improve the accuracy of requirement translation, the efficiency of batch execution and the precision of scene reproduction, transforming simulation testing from "manual organization"to "specification-driven". It provides a deployable, reusable and extensible engineering method for virtual verification of intelligent connected vehicles.
