Title:
MOVING BODY
Document Type and Number:
WIPO Patent Application WO/2016/147520
Kind Code:
A1
Abstract:
The purpose of the present invention is to inexpensively create a malfunction-sensing configuration for sensing malfunctions in the travel function of a moving body. A malfunction sensor of an electric wheelchair is provided with a first speed estimation unit for estimating the straight-travel speed of the electric wheelchair on the basis of an operation signal from an operation device, a second speed estimation unit for estimating the straight-travel speed of the electric wheelchair on the basis of an actual drive amount detected by an actual-drive-amount detection device, a speed difference calculator for calculating a first straight-travel speed difference which is the difference between the straight-travel speed estimated by the first speed estimation unit and the straight-travel speed estimated by the second speed estimation unit, and a malfunction determination unit for determining that there is a malfunction in the travel function when the first straight-travel speed difference calculated by the speed difference calculator is equal to or greater than a first straight-travel speed difference determination value.
