CarMaker model Driver-In-TheLoop on THE rFpro
VEHICLE DYNAMICS PROVING GROUND
A FICTITIOUS
BUT ENTIRELY
REPRESENTATIVE
VDPG WITH ALL THE
FEATURES OF A
REAL FACILITY
CarMaker model links directly to rFpro
Driver inputs via G27 / SensoWheel
Torque feedback CM -> rFpro -> Handwheel
Results:
No perceptible phase delay between input, graphics or feedback
Vehicle difficult to control in enthusiastic manoeuvres

Drivability Improvements - Driver-in-the-loop at Proving Ground
Needed to Develop - Yaw Damping - Drivability in higher speed manoeuvres
By refining - Elasto kinematics - Roll damping - Steering ratio & PAS - Limited Slip Differential

Result:
- Much improved Drivability
