Summary:To provide an ECU failure injection simulation device capable of shortening a work time required for failure injection verification of an ECU device and contributing to the reliability improvement of an ECU product by preventing a deterioration in the quality of the ECU product.SOLUTION: In an ECU failure injection simulation device, a plurality of computers for simulating reactions between an ECU device and a vehicle are arranged in parallel, a test pattern about a failure of the ECU device is given to each computer, and the reactions between the ECU device and the vehicle are simulated. The ECU failure injection simulation device includes estimation means for preliminarily estimating a simulation execution time of the test pattern in the computer, and distribution means for distributing an estimation time of the total amount of simulation execution times of the test pattern in the computers such that variation becomes small among the plurality of computers.SELECTED DRAWING: Figure 1 【課題】ＥＣＵ装置の故障注入検証に要する作業時間を短縮でき、ＥＣＵ製品の品質の低下を防止して、ＥＣＵ製品の信頼性向上に寄与することができるＥＣＵ故障注入シミュレーション装置を提供する。【解決手段】ＥＣＵ装置と車両との間での応動を模擬する複数の計算機を並列配置し、各計算機に対してＥＣＵ装置の故障についてのテストパターンを与え、ＥＣＵ装置と車両との間での応動をシミュレーションするＥＣＵ故障注入シミュレーション装置であって、計算機におけるテストパターンのシミュレーション実行時間をあらかじめ見積もる見積手段と、計算機におけるテストパターンのシミュレーション実行時間の合計の見積時間が、複数の計算機の間でばらつきが少なくなるように配分する配分手段を備えていることを特徴とするＥＣＵ故障注入シミュレーション装置。【選択図】図１
