PROBLEM TO BE SOLVED: To provide a method, equipment and a device for planning a vehicle speed.SOLUTION: This method includes: a step at which an initial plan speed at an object path point and a reference path point is determined based on curvature radiuses of an object front road and a reference front road so that first and second lateral accelerations are so made as to be no greater than a lateral acceleration threshold; and a step at which an object longitudinal direction acceleration and the object plan speed at the object path point are determined based on the initial plan speed and a reference itinerary at the object path point and the reference path point so that the object longitudinal direction acceleration falls within a regulated range. Consequently, a vehicle can avoid sudden deceleration and lateral direction off-set by traveling based on the object plan speed and the object longitudinal direction acceleration at the object path point, and therefore, travel safety and riding comfortability of the vehicle are improved, and energy can be saved.SELECTED DRAWING: Figure 2

    【課題】車両速度を計画する方法、機器、および装置を提供する。【解決手段】この方法は、対象前方道路および基準前方道路の曲率半径に基づいて、対象経路点および基準経路点における初期計画速度を決定することにより、第1および第2の横方向加速度が横方向加速度閾値よりも大きくならないようにするステップと、対象経路点および基準経路点における初期計画速度ならびに基準旅程に基づいて、対象経路点における対象縦方向加速度および対象計画速度を決定することにより、対象縦方向加速度が規定の範囲内となるようにするステップとを含む。したがって、車両は、対象経路点における対象計画速度および対象縦方向加速度に基づいて走行することにより、急激な減速および横方向オフセットを回避可能であるため、車両の走行安全性および乗車快適性が改善され、エネルギーが節約される。【選択図】図2
