Abstract: An industrial vehicle includes a driving device, a travel control device configured to control the driving device, an object detection unit, a first control unit setting a limit value, when a vehicle speed of the industrial vehicle is in a first vehicle speed range, a second control unit setting the limit value when the vehicle speed of the industrial vehicle is in a second vehicle speed range, and a speed limit unit imposing the speed limit according to the limit value. The first control unit includes a starting prohibition control unit that sets the limit value and a starting permission control unit that sets the limit value. The speed limit unit imposes the speed limit according to the limit value set by the first control unit when the limit value is set by the starting permission control unit.

Abstract: An industrial vehicle including: a direction calculation unit that calculates an instructed travel direction of the vehicle based on an operation position of the direction instruction member; a vehicle speed calculation unit that calculates an actual speed of the vehicle; a switching unit that switches between permission and prohibition of regenerative braking limit; and a control unit that controls traveling of the vehicle. The control unit is configured to be switchable between a regenerative braking limit state where the regenerative braking limit is performed and a regenerative braking limit release state where the regenerative braking limit is released, when the vehicle speed limit mode is activated and the regenerative braking limit is permitted. The control unit has at least one control pattern that switches between the regenerative braking limit state and the regenerative braking limit release state when a predetermined condition is satisfied.

Abstract: A forklift truck includes a main controller, a driving motor, a drive controller, and an object detector. The drive controller controls the driving motor. The object detector detects the position of an object being present in the backward direction of the forklift truck. The main controller derives an expected trajectory of the forklift truck. The main controller imposes a speed limit on the forklift truck by setting a vehicle speed upper limit when the object detected by the object detector is located within the expected trajectory and the forklift truck is traveling in the direction of approaching the object. The main controller gives commands to the drive controller to prevent the vehicle speed of the forklift truck from exceeding the vehicle speed upper limit.

Abstract: An engine-type industrial vehicle includes a power transmission; a main controller; an object detector configured to detect a position of an object; a predicted trajectory calculator configured to derive a predicted trajectory followed by a vehicle body; and a vehicle-speed upper-limit setter configured to impose a vehicle speed limitation on the vehicle body by setting a vehicle-speed upper-limit value when the detected object is positioned on the predicted trajectory and a traveling direction of the vehicle body is a direction toward the object. The main controller is configured to prevent a vehicle speed of the vehicle body from exceeding the vehicle-speed upper-limit value by performing at least one of a control so that a force acts in a direction in which movement of the vehicle body is prevented or a control so that a driving force to the driving wheel is cut off.

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: 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.

The power supply control apparatus includes a main relay and a ground relay, a pre-charge relay, an inrush current limiting resistor, a first relay control section, and a time measurement section. The main relay and the ground relay are connected between the battery and the load. The pre-charge relay is connected in parallel with one of the main relay and the ground relay. The inrush current limiting resistor is connected in series with the pre-charge relay, and limits an inrush current from the battery to the load. The first relay control section temporarily turns ON the pre-charge relay and turns ON the main relay and the ground relay upon receiving a power supply connection request from the outside, and turns OFF the main relay and the ground relay upon receiving a power supply interruption request from the outside.
