Abstract: A working vehicle includes: a vehicle body; and a boom; a bucket; a boom driving unit including a boom cylinder; a bucket driving unit configured to swing the bucket; a boom-bottom pressure sensor configured to detect a boom-bottom pressure of the boom cylinder; and a working equipment controller configured to control at least one of a lift motion of the boom and a tilt motion of the bucket. The bucket includes an inclined portion. The working equipment controller controls the lift motion or the tilt motion by comparing a threshold set in accordance with an inclination angle of the inclined portion with the boom-bottom pressure.

Abstract: A working vehicle (1) includes: a vehicle body (2); and a boom (31); a bucket (32); a boom driving unit including a boom cylinder (36); a bucket driving unit configured to swing the bucket (32); a boom-bottom pressure sensor (460) configured to detect a boom-bottom pressure of the boom cylinder (36); and a working equipment controller (10) configured to control at least one of a lift motion of the boom (31) and a tilt motion of the bucket (32). The bucket (32) includes an inclined portion (44). The working equipment controller (10) controls the lift motion or the tilt motion by comparing a threshold set in accordance with an inclination angle of the inclined portion (44) with the boom-bottom pressure.
Abstract translation: 工作车辆（1）包括：车体（2）; 和吊杆（31）; 桶（32）; 动臂驱动单元，包括动臂缸（36）; 铲斗驱动单元，其构造成使所述铲斗（32）摆动; 动臂底部压力传感器（460），其构造成检测动臂油缸（36）的悬臂底部压力; 以及工作设备控制器（10），其被配置为控制所述起重臂（31）的提升运动和所述铲斗（32）的倾斜运动中的至少一个。 铲斗（32）包括倾斜部分（44）。 工作设备控制器（10）通过将根据倾斜部分（44）的倾斜角度设定的阈值与悬臂底部压力进行比较来控制提升运动或倾斜运动。
