Classification: CPC G | IPC G

Claim 0:
1. A vehicle action simulation method comprising:
changing an attitude of a tire and a rotational speed of a rotary drum to reproduce a transient change in a tire attitude that occurs during travel of an actual vehicle on the tire in accordance with the behavior of the actual vehicle travel based on input information before a predicted behavior has been determined and based on the predicted behavior thereafter;
measuring a stress that is applied to the tire in contact with the rotary drum that is rotationally driven by a stress measuring portion, which is embedded on the rotatable rotary drum; and
calculating the tire ground contact characteristics on the basis of the measured stress,
wherein the calculated tire ground contact characteristics correspond to a tire attitude at each point in time during a period where the transient change occurs,
and predicting the behavior of the actual vehicle during travel based on vehicle characteristics predicted from the calculated tire ground contact characteristics,
wherein predicting the behavior of the actual vehicle during travel, changing the attitude of the tire and the rotational speed of the rotary drum, the measuring the stress that is applied to the tire, and calculating the tire ground contact characteristics on the basis of the measured stress are performed in parallel.
