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

Handling Track
