ABSTRACT:
A method of setting a parameter in a method of detecting a decreased tire air pressure for detecting a decreased tire air pressure based on a wheel rotational speed obtained from tires attached to a four-wheel driving vehicle. The method includes a vehicle model preparation step of preparing a vehicle model including a suspension member; a tire model preparation step of preparing a tire model; a step of inputting a friction coefficient between a tire and a road surface; and a simulation step of performing a running simulation of the vehicle model attached with the tire model. A determination parameter for determining whether the tire has a decreased air pressure or not is set based on wheel rotational speeds of the tires of the respective four wheels obtained in the simulation step.
