摘要： An apparatus and a method for controlling steering of an industrial vehicle includes a wheel angle detector, a travel determining device, and a control calculation device that calculates a wheel angle average and a maximum variation of wheel angle in the specified period and learns a reference steering limit angle. The control calculation device determines that the steerable wheel is in a steering limit state if an actual traveling speed is maintained at the specified speed or higher for the specified period of time or longer, the average wheel angle in the specified period of time is at a specified angle or greater, and the maximum variation of wheel angle in the specified period of time is at a specified value or less. The control calculation device renews the reference steering limit angle if the steerable wheel is determined to be in the steering limit state.

摘要： A current controller includes a current control circuit and a current detection circuit, which detects a current flowing through a solenoid of an electromagnetic proportional relief valve. The current control circuit sets a current command to a sum of a value obtained by multiplying a feedforward gain by a target current value, a value obtained by multiplying a proportional gain by a current deviation, and a value obtained by multiplying an integral gain by a current deviation integral value. The current control circuit then controls the current flowing through the solenoid in accordance with the current command. When the current detected by the current detection circuit is less than or equal to the predetermined value, the current control circuit resets the current deviation and the current deviation integral value and sets the current command based on the reset values.

摘要： A vehicle speed control device for an industrial vehicle is configured to control a vehicle speed of the industrial vehicle. The vehicle speed control device includes an operation detector that is configured to detect whether an accelerator pedal is being operated and a controller that is configured to control the vehicle speed of the industrial vehicle by controlling the rotation speed of the engine. The controller is configured to derive a vehicle speed limit value that increases during an operated state of the accelerator pedal and decreases during a non-operated state of the accelerator pedal, and set an upper limit value of the vehicle speed to the derived vehicle speed limit value.

摘要： An industrial vehicle includes a hydraulic mechanism, an operation lever, and a pump, a hydraulic control valve unit, a lever operation detector, an internal combustion engine controller, and a valve controller that controls the hydraulic control valve unit. When the lever operation detector detects the operation of the operation lever under a situation in which a speed of the internal combustion engine is less than or equal to a predetermined speed, the valve controller operates the hydraulic control valve unit to discharge the hydraulic oil without supplying the hydraulic oil to the hydraulic mechanism and instructs the internal combustion engine controller to increase the speed of the internal combustion engine, and subsequently operates the hydraulic control valve unit to supply the hydraulic mechanism with the hydraulic oil.

摘要： An industrial vehicle includes an engine, a hydraulic pump, a hydraulic operation device, a supply passage, a drainage passage, an unloading valve that connects the supply passage and the drainage passage to each other, and a controller that controls open/closed state of the unloading valve. If an on-load period at the time of application of load on the engine is less than a first predetermined time, the controller performs open/close control of causing the unloading valve to enter the closed state to set an on-load state, thereby increasing pressure of hydraulic oil passing through the supply passage and then causing the unloading valve to enter the open state.
