PROBLEM TO BE SOLVED: To provide a vehicle moment analysis device which can simulate with high reliability, in which a tire physical property in a state of steering without driving, is reflected, in a tire restoration moment generated around a king pin axis in the state of steering without driving of a vehicle.SOLUTION: A vehicle moment analysis device 100 comprises: a real steering angle measurement part 158 for measuring a real steering angle ψ formed with a direct advance direction of a vehicle 102 and a direction where a tire 108 is directed by steering; a tire property value measurement part 160 for measuring a tire property value; and a simulation part 152 for, using a tire model including an elastic force moment Mz1(ψ) based on a tire rigidity property obtained from the real steering angle ψ and the property value, and a friction force moment Mz2(ψ) based on a tire friction property, for approximating a restoration moment Mz(ψ) to the real steering angle ψ.SELECTED DRAWING: Figure 3
