To predict steering response, this paper proposes a string tire model based on relaxation length and a vehicle model designed by using effective cornering force. The cornering force, lateral static, and distortion characteristics of a tire are significant factors that describe steering response. Nevertheless, it is difficult to define the contribution of each factor when a tire's cornering motion is evaluated through subjective assessment. A new concept of tire model, which adopts distortion stiffness ( K D ), is defined. A modified vehicle dynamics model is adapted to represent tire force lag and converted cornering stiffness ( C ) based on effective cornering force. This integration scheme is proposed to provide a more accurate modeling for steering response performance. The integration model is confirmed by dynamic response and validated through comparison with a steering response assessment by a subjective test engineer. The test results demonstrate the ability of this approach to predict steering response.
