VEHICLE WEIGHT CALCULATION DEVICE, WAVY ROAD, AND VEHICLE WEIGHT CALCULATION METHOD
First Claim
1. A vehicle weight calculation apparatus that calculates a weight of a vehicle, the apparatus comprising:
- a storage section that stores position information and an angular frequency of a bumpy road in association with each other; and
a control section that calculates the weight of the vehicle, whereinthe control section calculates the weight of the vehicle based on acceleration of the vehicle in a vertical direction and the angular frequency of the bumpy road corresponding to a current position of the vehicle stored in the storage section.

Abstract
The purpose of the present invention is to make it possible to reduce the computation load for calculating vehicle weight and to allow vehicle weight to be computed with little error. Provided is a vehicle weight calculation device (10) that calculates the weight of a vehicle (1) and is provided with a storage unit (105) for associating and storing position information and angular frequencies of a wavy road, and a control unit (101) for computing the weight of the vehicle (1). The control unit (101) computes the weight of the vehicle (1) on the basis of the vertical acceleration of the vehicle (1) and the angular frequency of the wavy road corresponding to the current position of the vehicle (1) as stored by the storage unit (105).
