In such a vehicle test, it is required to measure the electric energy consumption rate (hereinafter, also simply referred to as "electric power cost") as one of the evaluation items. In this measurement of electricity cost, for example, as described in Patent Document 1, a running test of a vehicle is performed on a road or a chassis dynamometer, and the amount of power consumed in the running test is measured, and this power consumption and running are performed. Electric energy is calculated using the mileage in the test.
　従来、このような電費の測定では、例えば走行試験で測定された車両の消費電力量は、走行試験を管理するコンピュータにオペレータにより手入力され、この手入力された消費電力量に基づいて電費が算出されるのが一般的である。 Conventionally, in such measurement of electricity cost, for example, the power consumption of a vehicle measured in a driving test is manually input by an operator to a computer that manages the driving test, and the electricity cost is calculated based on the manually input power consumption. It is generally calculated.

　しかしながら、上記した電費の測定方法では、電力計等で測定した消費電力量を、オペレータが自ら電費算出用のコンピュータに手入力しているので、消費電力量を示す電力データに入力ミスが含まれる恐れがある。また、例えば複数の車両に対して走行試験や充電を行っており、電力データと走行距離を示す走行距離データとが複数存在している場合には、コンピュータに入力する電力データを取り違えてしまう恐れがある。 However, in the above-mentioned method for measuring the power consumption, since the operator manually inputs the power consumption measured by the power meter or the like into the computer for calculating the power cost, the power data indicating the power consumption includes an input error. There is a fear. Further, for example, when a running test or charging is performed on a plurality of vehicles and there are a plurality of mileage data indicating the mileage and the power data, there is a risk that the power data input to the computer may be mistaken. There is.
　そこで本発明は、走行試験における車両の電費を計測する電費計測システムにおいて、ヒューマンエラーによる電力データの入力ミスや取違えの発生を低減し、電費算出の精度を向上することを主たる課題とするものである。 Therefore, the main object of the present invention is to reduce the occurrence of input errors and mistakes in power data due to human error in the power cost measurement system for measuring the power cost of a vehicle in a running test, and to improve the accuracy of power cost calculation.

（１）走行試験工程
　まず車両Ｖの走行試験を実施する。具体的には、ソーク室内において満充電状態で保管されている完成車両Ｖを試験室に移動させ、シャシダイナモメータ１上にセットする（ステップＳ１）。当該車両Ｖに付された二次元コードを電力データ管理装置２３のカメラで撮影して車両識別子を読み込み、これを走行データ管理装置に転送する（ステップＳ２）。そしてシャシダイナモメータ１によりローラ１１を制御して、当該車両Ｖに対して所定の走行モードで走行試験を行う（ステップＳ３）。車両Ｖのモード走行の開始後、車両Ｖのバッテリの残量が所定値を下回ると、モード走行を終了させる。シャシダイナモメータ１のローラ１１の累積回転数に基づき、モード走行開始から終了までの車両Ｖの走行距離を算出し、走行試験開始前に取得した車両識別子と紐付けて記憶する（ステップＳ４）。なお、車両ＶがＰＨＶ（プラグインハイブリッドカー）である場合、ステップＳ３の走行試験は、車両Ｖのエンジンでの動作を停止させた状態で行うものとする。 (1) Running test process First, a running test of vehicle V is carried out. Specifically, the completed vehicle V stored in the soak chamber in a fully charged state is moved to the test chamber and set on the chassis dynamometer 1 (step S1). The two-dimensional code attached to the vehicle V is photographed by the camera of the power data management device 23, the vehicle identifier is read, and this is transferred to the travel data management device (step S2). Then, the roller 11 is controlled by the chassis dynamometer 1 to perform a running test on the vehicle V in a predetermined running mode (step S3). After the mode running of the vehicle V is started, when the remaining amount of the battery of the vehicle V falls below a predetermined value, the mode running is ended. Based on the cumulative rotation speed of the roller 11 of the chassis dynamometer 1, the mileage of the vehicle V from the start to the end of the mode running is calculated and stored in association with the vehicle identifier acquired before the start of the running test (step S4). When the vehicle V is a PHV (plug-in hybrid car), the running test in step S3 shall be performed with the operation of the vehicle V in the engine stopped.
（２）充電工程
　次に、走行試験後の車両Ｖを充電して再び満充電状態にする。具体的には、走行試験後、所定時間内にシャシダイナモメータ１上の車両Ｖをソーク室に移動させ、充電設備２１にセットする（ステップＳ５）。当該車両Ｖに付された二次元コードを電力データ管理装置２３のカメラで撮影して車両識別子を読み込む（ステップＳ６）。充電設備２１に接続されている電力計２２と電力データ管理装置２３との間の通信を確立し、電力データ管理装置２３を操作して、電力計２２による電力量の積算を開始する（ステップＳ７）。そして、充電ケーブルにより車両Ｖと充電用コンセント２１１を接続し、車両Ｖへの充電を開始する（ステップＳ８）。その後、電力データ管理装置２３により測定される積算電力量の変化率が所定値未満になり、車両Ｖのバッテリが満充電状態になったと判断すると、電力データ管理装置２３を操作して電力計２２による電力量の積算を終了する（ステップＳ９）。そして、積算を開始してから積算電力量の変化率が所定値未満になるまでの間における積算電力量を、充電開始前に取得した車両識別子と紐付けて記憶する（ステップＳ１０）。 (2) Charging step Next, the vehicle V after the running test is charged to make it fully charged again. Specifically, after the running test, the vehicle V on the chassis dynamometer 1 is moved to the soak chamber within a predetermined time and set in the charging equipment 21 (step S5). The two-dimensional code attached to the vehicle V is photographed by the camera of the power data management device 23, and the vehicle identifier is read (step S6). Communication between the power meter 22 connected to the charging equipment 21 and the power data management device 23 is established, the power data management device 23 is operated, and the integration of the electric energy amount by the power meter 22 is started (step S7). ). Then, the vehicle V and the charging outlet 211 are connected by the charging cable, and charging of the vehicle V is started (step S8). After that, when the rate of change of the integrated electric energy measured by the electric power data management device 23 becomes less than a predetermined value and it is determined that the battery of the vehicle V is in a fully charged state, the electric power data management device 23 is operated to operate the electric power meter 22. The integration of the electric energy according to the above is completed (step S9). Then, the integrated electric energy from the start of the integration until the rate of change of the integrated electric energy becomes less than a predetermined value is stored in association with the vehicle identifier acquired before the start of charging (step S10).
（３）電費算出工程
　最後に、測定した走行距離と積算電力量に基づいて、走行試験における車両Ｖの電費を算出する。具体的には、電力データ管理装置２３と走行試験管理装置３との間の通信を確立し、データを送受信できるようにする。そして、オペレータが走行試験管理装置３を操作して、電力データ管理装置２３から、走行試験管理装置３に保存されている走行距離データと車両識別子が一致する電力データを選択して取得する。走行試験管理装置３に取り込まれた電力データは、車両識別子が一致する走行距離データに紐付けられる（ステップＳ１１）。そしてオペレータが走行試験管理装置３を操作して、例えば走行試験管理装置３のディスプレイに表示された「電費計算」などのボタンをクリックすると、互いに紐づけられている走行距離データが示す走行距離と、電力データが示す電力量とに基づいて電費が算出され、その算出結果が表示される（ステップＳ１２）。 (3) Electric power calculation process Finally, the electric power of the vehicle V in the traveling test is calculated based on the measured mileage and the integrated electric energy. Specifically, communication is established between the power data management device 23 and the running test management device 3 so that data can be transmitted and received. Then, the operator operates the travel test management device 3 to select and acquire the power data in which the travel distance data stored in the travel test management device 3 and the vehicle identifier match from the power data management device 23. The electric power data taken into the travel test management device 3 is associated with the travel distance data having the same vehicle identifier (step S11). Then, when the operator operates the travel test management device 3 and clicks a button such as "electric energy calculation" displayed on the display of the travel test management device 3, the travel distance indicated by the travel distance data associated with each other is obtained. , The electric power cost is calculated based on the electric energy indicated by the electric power data, and the calculation result is displayed (step S12).
　このように構成した本実施形態の電費計測システム１００によれば、電費算出部３３が走行距離データと電力データとを自動的に紐付けるように構成されているので、電力データをオペレータが自ら入力することによるデータの入力ミスの発生を低減することができる。また、電力データと走行距離データはいずれも車両識別子とともに記憶されており、電費算出部３３は、車両識別子が一致する走行距離データと電力データを紐付けるようにしているので、例えば複数の車両Ｖに対して走行試験や充電が行われ、電力データと走行距離データが複数存在している場合であっても、異なる車両Ｖの電力データと走行距離データとが誤って紐付けられてしまうことを防止できる。これにより、電費算出の精度を向上することができる。 According to the power cost measurement system 100 of the present embodiment configured in this way, the power cost calculation unit 33 is configured to automatically link the mileage data and the power data, so that the operator inputs the power data by himself / herself. By doing so, it is possible to reduce the occurrence of data input errors. Further, both the electric power data and the mileage data are stored together with the vehicle identifier, and the electric power cost calculation unit 33 links the mileage data and the electric power data having the same vehicle identifier. Therefore, for example, a plurality of vehicles V Even if a running test or charging is performed on the vehicle and there are multiple power data and mileage data, the power data and mileage data of different vehicle Vs may be erroneously linked. Can be prevented. As a result, the accuracy of electricity cost calculation can be improved.
