BLADE CONTROL DEVICE AND BLADE CONTROL METHOD

A blade control device comprises: a correction design face generation unit to generate a correction design face that connects, in an initial design face indicating the target shape of an area to be excavated by a work vehicle blade, a first face present in front of the work vehicle and a second face having a slope different from the first face; and a blade control unit that outputs control instructions to control the height of the blade on the basis of the correction design face. 一种推土铲控制装置，具备：校正设计面生成部，其生成将初始设计面中存在于作业车辆的前方的第一面与坡度不同于第一面的第二面连接的校正设计面，其中初始设计面表示用作业车辆的推土铲进行挖掘的挖掘对象的目标形状；以及推土铲控制部，其基于校正设计面来输出用于控制推土铲的高度的控制指令。
