Background

Standardization Recommendation (STANREC) Development is a complementary activity to AVT-248 (January 2016 to December 2018) directed at the Development of a Next Generation NATO Reference Mobility Model (NG-NRMM). The efforts of AVT-248 are directed at improving the current NRMM, which predicts the capability of vehicles to move over specified terrains. NRMM is used for on-road and cross-country scenarios and it can account for parameters such as terrain type, moisture content, terrain roughness, vehicle design, and driver capabilities. Through development of this STANREC, NG-NRMM will become much more than a specific computer code. Rather, it will be a ground vehicle mobility modeling and simulation architectural specification. This TAP intends to support the commitment to the on-going maintenance and evolution of the NG-NRMM STANREC.

Objectives

This standard will be applicable to the full range of ground vehicle geometric scales and will provide: 1) standard M&S methods; 2) modular interoperability, portability, and future expansion, and 3) verification and validation scales and benchmarks appropriate to multiple levels of theoretical, geometric, and numerical model resolution.

Topics

The capabilities of NG-NRMM addressed by the STANREC are the following seven scientific thrust areas: 1. GIS-Terrain and Mobility Mapping: Identify a GIS-based mapping tool that implements and integrates existing valid mobility metrics (%NOGO and Speed Made Good) in an open architected environment. 2. Simple Terramechanics: Identify most promising existing terramechanics methods supporting NG-NRMM requirements that provide a means of correlating terrain characteristics to remotely sensed GIS data. 3. Complex Terramechanics: Establish a vision for the long-term terramechanics approaches that overcome the limitations of existing models. 4. Intelligent Vehicle Mobility: Identify unique mobility metrics and M&S methods necessary for mobility assessments of intelligent vehicles over a sliding scale of data and control system resolutions. 5. Uncertainty Treatment: Identify the practical steps required to embed stochastic characteristics of vehicle and terrain data to extend and refine the current deterministic mobility metrics. 6. Verification and Validation (V&V): Implement near-term vehicle-terrain interaction benchmarks for verification of candidate NG-NRMM M&S software solutions and lay the groundwork for long term validation data through cooperative development with test organizations standards committees. 7. Data Gaps and Operational Readiness: Refine the operational requirements of NG-NRMM and identify where the gaps exist.
