To provide a vehicle speed calculation device capable of suppressing deterioration in correction accuracy of a vehicle speed.SOLUTION: A vehicle speed calculation device comprises a target type determination unit, a vehicle speed calculation unit, a positional relation calculation unit, and a vehicle speed correction unit. When a target is an on-road object, the positional relation calculation unit calculates positional relation in a height direction between the vehicle and a fixed target based on an installation height of a radar sensor from a road surface, and when the target is an upper object, calculates positional relation in the height direction between the vehicle and the fixed target based on an up-down detection angle of the target detected by the radar sensor, or an up-down detection angle range of the radar sensor and a front-to-rear distance of the fixed target at the timing when the fixed target is lost from the up-down detection angle range. When the target is an on-road object, the vehicle speed correction unit increases the degree of correction of the vehicle speed using a relative vehicle speed compared to that when the target is the upper object.SELECTED DRAWING: Figure 6

    【課題】車両速度の補正精度の低下を抑制することができる車両速度算出装置を提供することを目的とする。【解決手段】車両速度算出装置は、物標種類判定部と、車両速度算出部と、位置関係算出部と、車両速度補正部と、を備えている。位置関係算出部は、物標が路上物である場合には、レーダセンサの路面からの設置高さに基づいて、車両と固定物標との高さ方向の位置関係を算出し、物標が上方物である場合には、レーダセンサによって検出された物標の上下検知角、又は、レーダセンサの上下検知角範囲及び固定物標が上下検知角範囲からロストしたタイミングにおける固定物標の前後距離に基づいて、車両と固定物標との高さ方向の位置関係を算出する。車両速度補正部は、物標が路上物である場合には、物標が上方物である場合に比べて、相対車両速度を用いた車両速度の補正の度合を大きくする。【選択図】図6
