PROBLEM TO BE SOLVED: To precisely estimate the vibration states of tires by using a vehicle model that is divided and layered into a vehicle body model, a chassis model, and a tire model. SOLUTION: The tire model 20 in the vehicle model is formed of a rear wheel tire model 21, a front wheel tire model 22, and a virtual coupling element model 23 that virtually couples the rear wheel tire model 21 and the front wheel tire model 22. Influence of the vibration state that is conducted between the front wheel tires and the rear wheel tires is considered while the tire model 20 and the chassis model 24 are separated from each other, thereby making it possible to estimate the vibrations that occur in the front wheel tires and the rear wheel tires.
