Leverage your investment in CarMaker
Model based Development Hardware integration early in lifecycle
Re-introduce the Human test driver into the Model Based Development Process
Test Vehicle Dynamics & ADAS with a human driver Before real hardware exists
Ensure ADAS works despite human driver
Reducing costs, shortening development cycles, improving quality and increasing the performance of a wide variety of automotive solutions
Calibrating CarMaker
- Driver-in-the-loop
Richard Hurdwell -
Concept chassis parameters with representative masses and
powertrain
Initial calibration - with IPG Driver
Steering Pad
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
