To provide a vehicle speed control device capable of appropriately controlling a vehicle speed when a vehicle travels through a curve while suppressing a sense of discomfort felt by a driver about the behavior of the vehicle.SOLUTION: A vehicle speed control device includes: a lane detection section 31 for detecting an own lane in which a vehicle 10 is traveling; a curvature estimation section 32 for detecting a start point at which a curved road section starts within a prescribed distance ahead of the vehicle 10, and estimating the curvature of the own lane in the road section; a determination section 33 for determining whether the own lane is a high-speed lane or a low-speed lane; a reference speed setting section 34 for setting a reference speed so that the reference speed of the vehicle 10 decreases as the curvature of the own lane increases, and so that the reference speed when the own lane is the high-speed lane is higher than the reference speed when the own lane is the low-speed lane; and a control section 35 for controlling the speed of the vehicle 10 so that the speed of the vehicle 10 when the vehicle 10 reaches the start point of the road section is equal to or lower than the reference speed.SELECTED DRAWING: Figure 3

    【課題】ドライバが車両の挙動に違和感を生じることを抑制しつつ、車両がカーブを走行する際の車速を適切に制御する車速制御装置を提供する。【解決手段】車速制御装置は、車両10が走行中の自車線を検出する車線検出部31と、車両10の前方の所定距離以内のカーブとなる道路区間が開始する開始地点を検出するとともにその道路区間における自車線の曲率を推定する曲率推定部32と、自車線が高速車線か、あるいは、低速車線かを判定する判定部33と、自車線の曲率が大きいほど車両10の基準速度が低くなり、かつ、自車線が高速車線である場合の基準速度が、自車線が低速車線である場合の基準速度よりも高くなるように、基準速度を設定する基準速度設定部34と、車両10が上記の道路区間の開始地点に達したときの車両10の速度が基準速度以下となるように車両10の速度を制御する制御部35とを有する。【選択図】図3
