Abstract: Northern environments cause unique terrain conditions for vehicle mobility, the most common of which are snow, ice and freezing or thawing ground. The cold regions mobility algorithms in NRMM (NATO Reference Mobility Model) were developed and implemented in the early 1990s. Meanwhile, vehicle technology has changed considerably and antilock braking, traction control, independent suspension, stability control and other drivetrain and suspension improvements are now common. Recently, we evaluated the legacy NRMM algorithms for 1) validation using modern vehicles; 2) updating sinkage algorithms for snow; 3) updating motion resistance calculations for snow; and 4) incorporating the use of chains or other traction multipliers for traction improvements on snow and ice. This paper presents recent work on validation and enhancements to the NRMM vehicle mobility model for snow and ice and the needs for future improvements.
