PROBLEM TO BE SOLVED: To maintain drivability during slope-descending by automatically increasing or decreasing a target vehicle speed of a vehicle according to gradient change of a traveling road surface during slope-descending speed control.SOLUTION: A slope-descending speed controller for a vehicle controls a vehicle so that the vehicle speed coincides with a target vehicle speed during slope-descending satisfying a predetermined condition. Further, the slope-descending speed controller for a vehicle includes: gradient change determination means for determining whether or not the gradient of a traveling road surface has changed by a predetermined amount or more; and target vehicle speed determination means for changing the target vehicle speed according to the amount of change in the gradient when it is determined by the gradient change determination means that the gradient of the traveling road surface has changed by the predetermined amount or more.SELECTED DRAWING: Figure 3
【課題】降坂速度制御時において、走行路面の勾配変化に応じて車両の目標車速を自動的に増減させ、降坂時におけるドライバビリティを保持すること。【解決手段】車両の降坂速度制御装置は、所定の条件を満たした降坂時に、車速が目標車速に一致するように車両を制御する。また、車両の降坂速度制御装置は、走行路面の勾配が所定量以上変化したか否かを判定する勾配変化判定手段と、前記勾配変化判定手段により前記走行路面の勾配が所定量以上変化したと判定した場合に、勾配の変化量に応じて前記目標車速を変更する目標車速決定手段と、を備える。【選択図】図3
