Abstract: In a first step of a watercraft control method, a command signal to activate an automatic cruise function is received. In a second step, a target vessel velocity of a watercraft is set. In a third step, an actual vessel velocity of the watercraft is obtained. In a fourth step, a command signal is generated that is a signal to perform an automatic cruise control to control a thrust of the watercraft such that a difference between the target vessel velocity and the actual vessel velocity falls in a predetermined range of values. In a fifth step, it is determined whether or not a predetermined interruption condition has been established. In a sixth step, a command signal is generated that is a signal to perform the automatic cruise control with the thrust having a different magnitude from the thrust to be generated under normal circumstances without establishment of the interruption condition when the interruption condition has been established.

Abstract: A hydraulic driving system includes first to third liquid-pressure pumps and control valves. The first boom control valve is connected to the first hydraulic pump, and the second arm control valve and the first bucket control valve are connected to the second liquid-pressure pump. Further, the turning control valve and the second bucket control valve are connected to the third hydraulic pump.

When the pilot pressure XAk0 is output from the bucket operating device while the turning operation is performed, the command switching device outputs a pilot pressure XAk2 to a second bucket control valve.

Abstract: A hydraulic drive system includes control valve and operating devices, a variable displacement pump, and a flow regulator. When an operating lever inclination angle becomes a value, a control valve opening area becomes a reference. When the operating lever inclination angle maximizes, the opening area maximizes. The flow regulator: until the operating lever inclination angle becomes the value, increases the pump discharge flow rate with the inclination angle, so a differential pressure between pump discharge and actuator load pressures is constant; when the operating lever inclination angle becomes the value, controls the pump discharge flow rate, so a control valve passing flow rate is an actuator maximum flow rate when the differential pressure is constant; and when the operating lever inclination angle is between the value and the maximum, defines a maximum pump discharge flow rate, so the pump discharge flow rate is kept to the actuator maximum flow rate.
