Abstract: 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.

Abstract: 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.

Abstract: An industrial vehicle has a vehicle travel mode including a vehicle speed control mode. The industrial vehicle includes an acceleration control member, a target vehicle speed calculator, a direction indicating member, a vehicle direction calculator, a vehicle speed calculator and a controller. The target vehicle speed calculator calculates a target vehicle speed based on an operation amount of the accelerator control member. The vehicle direction calculator calculates an instructing travel direction of the industrial vehicle based on a position of the direction indicating member. The vehicle speed calculator calculates an actual vehicle speed of the industrial vehicle. In the vehicle speed control mode, when the instructing travel direction is the same as an actual travel direction of the industrial vehicle and the target vehicle speed is lower than the actual vehicle speed, the controller maintains the vehicle travel mode in the vehicle speed control mode for controlling the traveling.

Abstract: An industrial vehicle includes a body, an axle pivotally supported by the body, a lateral acceleration sensor determining lateral acceleration applied to the body when the industrial vehicle is turned, an actuator temporally restricting pivoting of the axle while the industrial vehicle is being turned, a vehicle speed limiter limiting traveling speed of the industrial vehicle when the industrial vehicle is turned, and a controller driving the actuator based on the lateral acceleration determined by the lateral acceleration sensor to temporally restrict pivoting of the axle and to limit traveling speed of the industrial vehicle based on the lateral acceleration. In the controller a first lateral acceleration threshold value which is used in judging whether traveling speed of the industrial vehicle should be limited is set larger than a second lateral acceleration threshold value which is used in judging whether pivoting of the axle should be temporally restricted.

Abstract: 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.
