WEIGHT DETECTION DEVICE FOR VEHICLE AND METHOD FOR DETECTING WEIGHT OF VEHICLE COMPONENT
First Claim
1. A weight detection device configured to detect a weight of a vehicle body of a vehicle, the vehicle including a wheel and the vehicle body connected with each other via a suspension having a spring, the weight detection device comprising:
- an oscillation detection unit configured to detect an oscillation of the vehicle body in forward and backward directions;
a resonance frequency detection unit configured to detect a resonance frequency of the vehicle body according to the oscillation detected by the oscillation detection unit; and
a weight determination unit configured to determine a weight of the vehicle body according to the resonance frequency detected by the resonance frequency detection unit.

Abstract
A vehicle includes a wheel and a vehicle body connected with each other via a suspension having a spring. An oscillation detection unit detects an oscillation of the vehicle body in forward and backward directions. A resonance frequency detection unit detects a resonance frequency of the vehicle body according to a detection result of the oscillation detection unit. A weight determination unit determines a weight of the vehicle body according to the resonance frequency detected by the resonance frequency detection unit.
