Position estimation system, position estimation unit, work machine, and extension unit
A position estimation system (50) is provided with a bucket angle sensor (66) and a controller (54). The first work machine (25) has a forearm (11), a bucket (13), and a bucket cylinder (21) that drives the bucket (13), and is swingable with respect to the vehicle body (2). The extension arm (12) has a link mechanism (32) for transmitting the drive of the bucket cylinder (21) to the bucket (13), and can be fitted between the forearm (11) and the bucket (13). The bucket angle sensor (66) can be disposed on the link mechanism (32). The controller (54) estimates the position of the tip (13p) of the bucket (13) on the basis of the shape data of the first work machine (25), the shape data of the extension arm (12), the information relating to the orientation of the first work machine (25), and the detection value of the bucket angle sensor (66).
位置推定系统(50)具备铲斗角传感器(66)和控制器(54)。第一工作装置(25)具有小臂(11)、铲斗(13)及驱动铲斗(13)的铲斗缸(21)，能够相对于车辆主体(2)摆动。伸长臂(12)具有将铲斗缸(21)的驱动传递到铲斗(13)的连杆机构(32)，能够装配于小臂(11)和铲斗(13)之间。铲斗角传感器(66)能够配置于连杆机构(32)。控制器(54)基于第一工作装置(25)的形状数据、伸长臂(12)的形状数据、与第一工作装置(25)的姿势相关的信息、以及铲斗角传感器(66)的检测值，推定铲斗(13)的铲尖(13p)的位置。
