Background and Goal
Simulation Design Requirements
Simulation Design Features
Conclusions
Briefing Outline
Background
-Increased fidelity and use of Driving Simulators-New vehicle designs are exploring advanced driving interfaces
(displays, controls, information)
Current Effort- Design a virtual motion simulation to enable
- trade studies- supplement Crew station tech demos(e.g. FTTS, CAT)
…that models the ground vehicle dynamics environment.
Goal-Satisfy FCS, Objective Force mobility, human factors requirements
-“operate on-the-move” (tele-ops, C2, increased op tempo) -“function without adverse physical effects” (mitigate sickness, info overload)
Simulation Design Requirements
Displays – mimic two-man crew, head mounted & flat panelMotion – full 6 DOFProtocol – Design of Experiments (DOE)Console – wheeled vehicle with control loadingVehicle Dynamics – multi-body, Stryker designDatabase – turns, hills, cross-countryAudio – own vehicle soundsData Acquisition – to enable results of trades
Simulation Design Features
Cab display
Console
Symbology
Terrain/database
3-panel, 120x30 FOV, 21 inch
Steering loader, brake, accel, gear
Heading, speed, gearIntegrated with display
Roads, turns, features
Simulation Design Features (Cont’d)
HMD
Head Trackers(2)
Vehicle Dynamics
Motion Base, Audio
COTS, Kaiser ProView™, XL 50, 40x30 FOV
Multi-body, reacts to terrainand driver inputs
COTS, InterSense InertiaCube™Mounted on head and motion base Full 6-DOF, motion, audio cues
Experiment Protocol
Design of ExperimentsTwo fixed factors – HMD versus flat panelAnalysis - Independent variables: Fixed factorial, repeated measures2x4x2 (displays x vibration levels x course segments)
Dependent variables: road following, speed, long and latacceleration, steering wheel reversals, questionnaire ratings
12 subjects, civilian local population
Separate Multivariate ANOVAs- Vibration and course segments
Questionnaires(9) ANOVA
Determine influence ofdisplays, vibration, courseon driver performance.
Conclusions
Experiment not yet conducted (stay tuned)
Simulation design set up for vehicle/crew-station trade studies-Effects of Active, Passive Suspension, hybrids on Crew Performance-Joystick, yoke, steering wheel controls…feed-through vibration, and road feel characteristic settings?
-Optimum display design – what data & information to display,how to best render data – to make informed decisions
-Optimize camera locations
-Relatively? easy to modify simulation for tele-operations, UGV studies
