Calibration assisting method, device and system

A calibration assisting device includes a reference load data storage means 30 d for storing, as a reference load data, the reference load data produced from load sensor 10 when a desired reduced quantity is generated in a vehicle weight measuring device 40 , a load data fetching means 30 a 1 for fetching the load data produced from the load sensor 10 , a tire load data fetching means 30 a 2 for fetching a tire load data produced from the vehicle weight measuring device 40 , a reduced quantity detecting means 30 a 3 for detecting a reduced quantity on the basis of the tire load data thus fetched, a calibration information creating means 30 a 4 for creating calibration information on the basis of the load data fetched by the load data fetching means 30 a 1 corresponding to the tire load data and the reference load data stored in the reference load data storage means 30 d when the reduced quantity is detected, and a calibration information outputting means 30 a 5 for outputting the calibration information produced from the calibration information creating means 30 a 4 . In such a configuration, the calibration assisting device can assist the calibration of the weight meter.
