Introduction
• Preamble-“What”
• Motivation- “Why”
• Analysis Overview- “How”
Vehicle Dynamics Simulation Results
• Vehicle dynamics - remarks
• Skidpad
• Nurburgring Race Track
Simulation results are presented for
• Baseline vehicle -RWD
• Torque Vectoring Rear Axle- “Driveline” system
• Four Wheel Steer- “Chassis” system
• The handling performances are compared
• Steady state (skid pad) and
• Dynamic simulations (race track)
Conclusions – TVS & 4WS
• Cornering performance is enhanced (higher lateral
acceleration and yaw rate)
• High body slip angles can be sustained without loss of
control
• Steering angle requirement is cut down in spite of higher
lateral acceleration
