Abstract:
1. A vehicle state analyzing method, comprising: a suspension/chassis setting step for setting an optimum alignment state in a suspension/chassis of a vehicle; an initialize mode measuring step in which a lateral force from all wheels to a vehicle body is measured, by using a force sensor for detecting input of force from each wheel to the vehicle body, when the vehicle, which is set to an optimum alignment state, is run on a substantially flat road surface as reference under a predetermined condition, and deviation of fluctuation or fluctuation rate of the lateral force with respect to the optimum alignment state is measured; a monitor mode measuring step in which the lateral force is measured, by using the force sensor, when the vehicle, which has run a predetermined distance or for a predetermined time from a time of performing the initialize mode measuring step, is run on a substantially flat road surface, and deviation of fluctuation or fluctuation rate of the lateral force with respect to the optimum alignment state is measured; and an analyzing step in which a change of the alignment state of the vehicle is analyzed on the basis of a ratio of the deviation obtained at the monitor mode measuring step and the deviation obtained at the initialize mode measuring step.
