Vehicle basic characteristic
measurement contract test(K&C TEST)

※As of October 2021

- Usage -

Suspension and steering system parameter

Acquisition of input data for various vehicle simulation software

- Compatible simulation software -

■ Carsim ■ Carmaker ■ VI-CarRealTime

※We also support simulation software other than the above.

Measuring changes in suspension geometry

Measurement of suspension stiffness properties

Measurement item

  • Tire ground contact 4 component forceVertical direction・Left-right direction・Longitudinal direction・Aligning torque
  • Wheel alignment change measurementCamber angle・Caster angle・Toe angle・Front-back displacement・Left-right displacement・Vertical displacement
  • Tire ground contact displacementVertical direction・Left-right direction・Longitudinal direction・Aligning angle
