发明名称 WORKS VEHICLE AND METHOD FOR CONTROLLING WORKS VEHICLE
摘要 A pump displacement control cylinder is configured to control the displacement of a hydraulic pump according to pressure of hydraulic fluid which is supplied to the pump displacement control cylinder. The pump displacement control cylinder is configured to switch the discharge direction of the hydraulic fluid from the hydraulic pump according to the supply direction of the hydraulic fluid to the pump displacement control cylinder. A forward and backward progression switching valve is configured to switch the supply direction of the hydraulic fluid to the pump displacement control cylinder. A pressure control valve is configured to control the pressure of the hydraulic fluid which is supplied to the pump displacement control cylinder according to a command value which is input to the pressure control valve. A forward and backward progression operation member is configured to be operated in order to switch forward and backward progression of the vehicle. A control section is configured to execute pump shuttle control which reduces the command value to the pressure control valve when switching between forward and backward progression using the forward and backward progression operation member.
