Steering Performance

E-mail Print PDF

Objective testing of steering performance is typically the most repeatable and used for tire, damper and suspension development or competitive vehicle benchmarking programs. Testing includes low-g sine-steer, swept steer, parking efforts, frequency response and returnability tests.  Maneuvers are performed at various predetermined speeds or specific speeds requested by the customer or dictated by the vehicle.

Sensor set (typical)
 Steering Wheel Angle
 Steering Wheel Torque
 Yaw Rate
 Lateral Acceleration
 Vehicle Speed
 Vehicle Position

 Output Data (sample, not all-inclusive)
 Yaw Rate Gain
 Lateral Acceleration Gain
 Torque/Angle Deadband
 On-Center Torque/Angle
 Friction/Hysteresis
