PROBLEM TO BE SOLVED: To solve the problem of appropriately not copying with a change in a situation in which a carrier is placed, a loading condition, or the like.SOLUTION: A power-assisted carrier 1 includes: a motor 12 for driving a carrier having an operating handle and wheels; an operation force acquisition part 11 for acquiring operation force to an operating handle; a storage part 14 for storing operation specification information for associating operation force when a user operates a carrier 2 during non-operation of the motor 12 with acceleration; a target operation acquisition part 15 for using the operation specification information to acquire target operation information being acceleration corresponding to the acquired operation force; a present value acquisition part 13 for acquiring a present speed of the motor 12; and a control part 16 for controlling the motor 12 such that the present speed becomes a speed corresponding to the target operation information. As a result, power assistance is performed such that a similar operation is performed in accordance with a similar operation when the user operates the carrier during non-operation of the motor 12 regardless of a situation in which the carrier is placed.SELECTED DRAWING: Figure 2
【課題】台車の置かれている状況や積載状況等の変化に適切に対応することができないという問題があった。【解決手段】パワーアシスト台車1は、操作用ハンドル及び車輪を有する台車、車輪を駆動するモータ12、操作用ハンドルへの操作力を取得する操作力取得部11、モータ12の非動作時にユーザが台車2を操作した際の操作力と加速度とを対応付ける動作特定情報が記憶される記憶部14、動作特定情報を用い、取得された操作力に応じた加速度である目標動作情報を取得する目標動作情報取得部15、モータ12の現在速度を取得する現在値取得部13、現在速度が目標動作情報に応じた速度となるようにモータ12を制御する制御部16を備える。その結果、台車の置かれている状況等に関わらず、ユーザがモータ12の非動作時に操作したときと同様の操作に応じて同様の動作が行われるようにパワーアシストが行われる。【選択図】図2
