CDT SRD Appendix D – Version 2.0 21 June 2018 i

Scope This appendix describes the requirements for the Tactical Wheeled Variant (TWV) simulated vehicle driver’s compartment hardware and software. When the driver’s compartment installed on a Common Driver Trainer (CDT) platform, the collective system becomes a CDT TWV that provides training for drivers of various types of TWV vehicles. The CDT TWV will provide training of TWV vehicles to drivers during New Equipment Training (NET) and sustainment training. The trainer will enable training in the critical driver tasks that can repetitively train in a simulator. It will also allow training of driver tasks that are dangerous and/or infrequently trained in the "real world" (driving on ice, fording streams, driving under blackout conditions, driving down a steep embankment when coming off an improved road, etc.).

This appendix contains the requirements for the vehicle specific kits. Each kit includes the vehicle specific driver’s compartment hardware and simulation software needed to convert the base CDT TWV to match a specific vehicle’s physical and functional characteristics.

1.1. Background

The U.S. Army has identified a need for initial and sustainment driver training for the various tracked, wheeled, and heavy equipment vehicles employed by the Army to accomplish its mission. The U.S. Marine Corps (U.S.M.C.) has equivalent driver training requirements with unique vehicle variants required to accomplish its mission. The CDT will be dual use and support both the U.S. Army and the U.S. Marine Corps with driver training capability for the identified military vehicles. The training must incorporate a variety of terrains, driving conditions and tactical situations.

A CDT configuration composes of common training subsystem modules. The common modules are the Instructor Operator Station (IOS), computational subsystem, visual/display subsystem, aural/communication subsystem, motion subsystem, After Action Review (AAR) subsystem and Scenario Generation System. The CDT subsystems have documented hardware, software and electrical configurations and interfaces for simulated variant vehicle driver’s compartment installation.

The vehicle variant subsystem includes the driver’s compartment module and simulation software necessary to provide the configuration and vehicle dynamics of the variant vehicle. The main components of the driver’s compartment module are the controls, instruments, switches, panels, seating and physical structure of the variant vehicle necessary to accomplish the required training tasks. The simulation software provides the driver’s compartment control/switch interaction and simulator response for the controls, instruments, switches, and panels necessary to accomplish the required training tasks.

1.1.1 TWV

The CDT TWV is a variant for the CDT. This variant will include the specific modules necessary to provide the configuration and vehicle dynamics of the TWV family of vehicles. The CDT TWV will use all of the common modules as specified in the CDT Common Specifications Requirements Document (SRD) and the specific modules for the TWV as defined herein. The main components in the specific modules are the driver compartment, swappable vehicle specific dash panels with instruments and controls for the driver, space and visual constraint modules (if necessary) and the software required to operate the driver compartment and interact with the common modules in the CDT.
