摘要： 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.

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

摘要： 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.

摘要： 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.
