PROBLEM TO BE SOLVED: To set the range and timing of buffering of the position information data of a preceding vehicle for preventing a deterioration in the calculation accuracy of a travel track without excessively increasing an arithmetic load in a configuration in which the travel track of the preceding vehicle is calculated for preceding vehicle track control as the driving support control of a vehicle.SOLUTION: A preceding vehicle travel track calculation device is configured to determine a range (buffering range D) of a distance of the position information data of a preceding vehicle stored so as to be used for calculating a preceding vehicle travel track on the basis of an error of the position information data of the preceding vehicle, and to store the position information data of the preceding vehicle in a storage period (buffering timing) of the position information data of the preceding vehicle determined on the basis of the buffering range D, and to calculate the travel track of the preceding vehicle by using the position information data in the buffering range D among the stored position information data of the preceding vehicle.SELECTED DRAWING: Figure 4

    【課題】 車両の運転支援制御としての先行車追跡制御のために先行車の走行軌跡の算出する構成に於いて、演算負荷を過大にせずに、走行軌跡の算出精度の低下を防止できるように、先行車の位置情報データのバッファリングの範囲とタイミングを設定すること。【解決手段】 本発明の先行車走行軌跡算出装置は、先行車の位置情報データの誤差に基づいて、先行車走行軌跡算出のために保存され利用される先行車の位置情報データの距離の範囲(バッファリング範囲D)を決定し、そのバッファリング範囲Dに基づいて決定された先行車の位置情報データの保存時期(バッファリングのタイミング)に先行車の位置情報データを保存し、保存された先行車の位置情報データのうちのバッファリング範囲D内の位置情報データを用いて、先行車の走行軌跡を算出する。【選択図】 図4
