A bias estimation device includes a determination unit configured to determine whether a forklift is stationary based on a measurement value from a first sensor configured to detect information regarding movement of the forklift and a measurement value from a second sensor configured to detect information regarding a cargo handling device included in the forklift, an accumulation unit configured to accumulate an IMU measurement value that is a measurement value from an inertial measurement unit included in the forklift when the determination unit determines that the forklift is stationary and stop accumulation of the IMU measurement value when the determination unit determines that the forklift is not stationary, and a calculation unit configured to calculate a bias of the IMU measurement value based on the IMU measurement value accumulated in the accumulation unit.

A control method for a mobile object is a control method for a mobile object that automatically moves. The control method includes detecting a position of a target object to be conveyed with respect to the mobile object, and acquiring, based on a detection result of the position of the target object, positional information on the target object indicating the position of the target object with respect to the mobile object in a state in which a fork disposed on the mobile object is inserted into a hole formed on the target object.

A position identification system includes a point group acquisition part 22 that horizontally irradiates light into a space above a loading platform Ta to acquire a point group PG, an analysis part, and a position identification part. The analysis part analyzes the acquired point group PG using frequency distribution with a distance in the X-axis direction as an axis. The position identification part identifies a region D 2 with substantially no frequency as a cargo placing space based on an analysis result of the point group PG, and identifies sections S 1 and S 2 with a predetermined frequency or more adjacent to the cargo placing space as the positions of edges in the X-axis coordinate of an object adjacent to the cargo placing space.

A visibility support system includes: a positioning unit that estimates a position of an industrial vehicle; a route prediction unit that predicts a route of a part of the industrial vehicle or an object moving together with the industrial vehicle with reference to the position estimated, and calculates an interference position at which an obstacle interferes with the route on the basis of map data containing position information of the obstacle; a display unit configured to be worn on a head of a person, the display unit having transparency and being capable of displaying image data; and a control unit that displays image data of the route such that the image data is superimposed on a position of the route in a real world viewable through the display unit, the route starting from the part or the object at the position estimated and ending at the interference position.

An unmanned carrier vehicle switchable between normal and lateral driving mode includes: wheels (a left front wheel, a right front wheel, a left rear wheel, and a right rear wheel), a drive unit that restricts rolling of the left front wheel and the left rear wheel, a steering device that changes direction of the wheels, and a control device. The control device controls the steering device to change direction of the right front wheel and the left rear wheel after changing direction of the left front wheel and the right rear wheel when switching between normal and lateral driving mode; and further controls the drive unit to restrict rolling of the left rear wheel when changing direction of the left front wheel and the right rear wheel, and to restrict rolling of the left front wheel when changing direction of the right front wheel and the left rear wheel.

An industrial vehicle has a first mode and a second mode. The industrial vehicle includes: a detection device configured to detect a person and/or an object in a surrounding region of the industrial vehicle and a person in a driver's seat as a detection target; a notification device configured to output an alarm by light and/or sound; a notification control part that causes the notification device to output the alarm upon detection of the detection target by the detection device; and a mode selection part operated to cause the industrial vehicle to transition to the first mode and the second mode. The detection device includes a range setting part that sets the surrounding region as a detection range to detect the detection target without setting the driver's seat as the detection range in the first mode, and sets the driver's seat as the detection range in the second mode.

A transport vehicle is provided, which is capable of adjusting a cargo loading position afterward even if a mobile shelf, a truck, or the like deviates from a predetermined position. The transport vehicle 1 includes: forks 16 ; a point group acquisition unit 22 that acquires a point group PG by horizontally irradiating a laser; and a distance specifying unit that specifies a distance in a left-right direction between the cargo loaded on the forks 16 and an object adjacent to a cargo loading position based on the acquired point group PG. The point group acquisition unit 22 is arranged at a position to be capable of irradiating the cargo loaded on the forks 16 and the cargo loading position with a laser.

A position estimation system is a position estimation system for estimating a position of a forklift equipped with a camera and includes: a position estimation unit configured to estimate a position of the forklift on the basis of a feature included in an image captured by the camera; and an inclusion determination unit configured to calculate, on the basis of a position in a height direction of a mast with which the forklift is equipped, an inclusion range indicating a range in which the mast is in the image and determine to stop estimation of the position by using the position estimation unit when the inclusion range calculated exceeds an allowable range.

An alert system includes a vehicle control unit controlling a traveling device and a cargo handling device, an alarm device outputting an alarm by sound and/or light, and an information processing device connected to the vehicle control unit and the alarm device. The information processing device includes an event detection unit detecting a hazardous event based on vehicle information, an alarm control unit activating the alarm device when the event detection unit detects any of the hazardous events, and causes the alarm device to output an alarm, and a restriction command unit transmitting a restriction command to the vehicle control unit to restrict operation of the cargo handling vehicle when the event detection unit detects a part of specific hazardous events among the hazardous events. When receiving the restriction command, the vehicle control unit restricts traveling operation of the traveling device and/or cargo handling operation of the cargo handling device.
