To flexibly collect vehicle data before and after collection conditions for vehicle data are met, while suppressing oppression on communication and cost increase.SOLUTION: A vehicle data collection device 5 includes: a setting unit 40 for determining a collection setting which is setting information to each ECU in response to a collection request; a collection condition determination unit 51 that sets collection conditions based on the collection setting and determines whether or not the collection conditions are met: a collection data output unit 52 that sets collection data based on the collection setting and acquires the collection data from each ECU; a multi-stage retention unit 53 that holds the collection data before the collection conditions are met and the collection data after the collection conditions are met based on the collection setting; a transmission standby unit 60 that waits for transmission of the held collection data; and a transmission unit 31 that transmits the collection data that is on standby in transmission standby unit 60 to the request source. The collection request includes a set value related to the number of the held collection data in the multi-stage retention unit 53. The setting unit 40 determines the collection setting by changing the number of the held collection data by the multi-stage retention unit 53 from the set values.SELECTED DRAWING: Figure 3

    【課題】通信圧迫及びコスト増加を抑制しながら、車両データの収集条件が成立する前後の車両データを柔軟に収集することを目的とする。【解決手段】車両データ収集装置5は、収集要求に応じた各ECUへの設定情報である収集設定を決定する設定部40と、収集設定に基づいて収集条件を設定し、収集条件が成立するか否かを判定する収集条件判定部51と、収集設定に基づいて収集データを設定し、収集データを各ECUから取得する収集データ出力部52と、収集設定に基づいて、収集条件成立前の収集データと収集条件成立以降の収集データとを保持する多段保持部53と、保持された収集データの送信を待機させる送信待機部60と、送信待機部60に待機された収集データを要求元に送信する送信部31と、を備える。収集要求は、多段保持部53の収集データの保持数に関する設定値を含む。設定部40は、多段保持部53の収集データの保持数を当該設定値から変更して収集設定を決定する。【選択図】図3
