PROBLEM TO BE SOLVED: To accurately detect a preceding vehicle when making a turn to right or left following the preceding vehicle.SOLUTION: An automatic vehicle speed control device 10 comprises: a first detecting portion 161 that detects a preceding vehicle travelling in front of its own vehicle and detects relative speed and an inter-vehicle distance between its own vehicle and the preceding vehicle; an automatic vehicle speed control portion 162 that automatically controls vehicle speed of its own vehicle on the basis of a detected situation of the preceding vehicle, the relative speed and the inter-vehicle distance; a second detecting portion 163 that detects its own vehicle makes a turn to right or left at an intersection where the vehicle enters; and a detection range control portion 165 that when the second detecting portion 163 detects that the vehicle makes a turn to right or left at the intersection, widens a detection range of the preceding vehicle 2 by the first detecting portion 161 in a direction in which the vehicle makes a turn to right or left.SELECTED DRAWING: Figure 2

    【課題】先行車両に追従して右左折する場合に先行車両を精度良く検出する。【解決手段】車速自動制御装置10は、車両の前方を走行する先行車両を検出し、車両と先行車両との相対速度及び車間距離を検出する第1検出部161と、先行車両の検出状況、相対速度、及び車間距離に基づいて、車両の車速を自動的に制御する車速自動制御部162と、車両が進入する交差点において、車両が右左折することを検出する第2検出部163と、交差点において車両が右左折することを第2検出部163が検出すると、第1検出部161による先行車両2の検出範囲を、車両が右左折する方向に拡大する検出範囲制御部165とを備える。【選択図】図2
