PROBLEM TO BE SOLVED: To provide a vehicular control device that controls a vehicle-body speed so that the speed does not exceed a target speed during traveling on a downhill without brake operation by a driver, which can improve a driving feeling.SOLUTION: A control portion 100 of a vehicular control device, which controls a vehicle-body speed so that the speed does not exceed a target speed during traveling on a downhill without brake operation by a driver, comprises: target speed setting means 130 that sets the target speed; and speed suppression/control executing means 150 that executes speed suppression/control for imparting braking force to a vehicle on the basis of the target speed and present vehicle-body speed during traveling on a downhill. The target speed setting means 130, when the vehicle-body speed is reduced by a predetermined value or more in a state where brake operation and acceleration operation are not performed while the speed suppression/control is not executed, sets, on the basis of the present vehicle-body speed, the target speed to a speed slower than a first target speed to be set according to the operation by a driver.SELECTED DRAWING: Figure 3 【課題】下り坂を走行中に運転者のブレーキ操作によらずに目標速度を超えないように車体速度を制御する車両制御装置において、運転フィーリングを向上させることを目的とする。【解決手段】車両制御装置の制御部１００は、下り坂を走行中に運転者のブレーキ操作によらずに目標速度を超えないように車体速度を制御する装置であって、目標速度を設定する目標速度設定手段１３０と、下り坂を走行中に、目標速度と現在の車体速度に基づいて車両に制動力を与える速度抑制制御を実行する速度抑制制御実行手段１５０とを備える。目標速度設定手段１３０は、速度抑制制御の非実行中にブレーキ操作およびアクセル操作が行われていない状況で車体速度が所定量以上減少した場合、目標速度を、現在の車体速度に基づき、運転者の操作に基づいて設定される第１目標速度よりも小さい値に設定する。【選択図】図３
