Title:
WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/038268
Kind Code:
A1
Abstract:
A wheel loader (1) comprising steering cylinders (21, 22), a steering pump (31a), a joystick lever (24), a pilot valve (42), an angular velocity corresponding value detection unit (27), a notification unit (29), and a control unit (28). The pilot valve (42) controls the flow rate for oil supplied from the steering pump (31a) to the steering cylinders (21, 22), on the basis of the joystick lever (24) operation amount. The angular velocity corresponding value detection unit (27) detects a corresponding value corresponding to a steering angular velocity that changes on the basis of the oil flow rate. The notification unit (29) sends, to an operator, a notification indicating that the corresponding value has reached a pre-set threshold value, on the basis of the upper limit of the steering angular velocity. If the control unit (28) detects that the corresponding value has reached the threshold value, the control unit (28) causes the notification unit (29) to make a notification.
