A processing device comprising a graphical user interface in an industrial vehicle is provided. The processing device comprises a touch screen display that receives touch gesture commands from a vehicle operator, memory storing executable instructions, and a processor in communication with the memory. The processor when executing the executable instructions: defines a plurality of widgets, wherein each widget comprises a visual representation of a current state of an associated function of the vehicle, displays a subset of the plurality of widgets on a portion of the touch screen display defining a plurality of widget spaces, and displays an icon tray on the touch screen display comprising one or more icons, in which at least one of the one or more icons corresponds to a respective one of the plurality of widgets.

Apparatuses, systems and methods associated with powered vehicles are disclosed herein. In examples, a system for controlling a vehicle may include sensors and a processor coupled to the sensors. The processor may identify one or more values received from the one or more sensors, wherein the one or more values are associated with one or more conditions of the vehicle and/or the vehicle's environment, and determine, based on the one or more values, a net resultant force vector of one or more forces acting on a center of mass of the vehicle. The processor may further determine a relationship between the net resultant force vector and a stability polygon that is superimposed at a base of the vehicle, and determine whether to limit one or more of a speed, rate of change, and/or travel amount for one or more of the operational systems controlled by the processor based on the relationship between the net resultant force vector and the stability polygon. Other examples may be described and/or claimed.

A forklift includes: an armrest that is provided at a driver's seat of a vehicle and is moved between a non-operation position and an operation position by a movable mechanism; a steering member that outputs an operation signal in response to a steering operation; a steering device that changes a steering angle of steering wheels of the vehicle; a control unit that changes the steering angle according to the operation signal; and an armrest detection unit that detects whether the armrest is at the non-operation position or at the operation position in which when the armrest detection unit detects that the armrest is at the non-operation position, the control unit controls the steering device or the steering member such that the steering device does not change the steering angle even if the steering member is operated.

The disclosure provides a vehicle approach notification device and a picking truck. The vehicle approach notification device includes a first illumination portion provided on a cab capable of elevation; a second and a third illumination portion provided on a vehicle body incapable of elevation; and a control unit that (1) turns on the first illumination portion and off other illumination portions when a travel state of the vehicle body is backward travel and an elevation position is lower than a predetermined threshold value; (2) turns on the second illumination portion and off other illumination portions when the travel state is backward travel and the elevation position is equal to or higher than the threshold value; (3) turns on the third illumination portion and off other illumination portions when the travel state of vehicle is forward travel; and (4) turns off all illumination portions when the travel state is travel stop.

A forklift overturning prevention method includes: acquiring a wheel load on a wheel of a forklift; obtaining a center of gravity of the forklift based on wheel loads on all wheels of the forklift; and sending a protection operation instruction when the center of gravity reaches a preset boundary line, so that the forklift stops working and sounds an alarm to prevent the forklift from overturning.

A wheel load estimation device includes an obtaining unit obtaining angular velocities and angular accelerations of a rigid body including an element, accelerations of the rigid body in a front-rear direction and in a lateral direction, a weight of the element, and a position including a height of the element. The element fluctuates a center of gravity of the rigid body. A center-of-gravity inertia value calculation unit calculates information relevant to the center of gravity of the rigid body and an inertia value. A wheel load variation calculation unit calculates variation amounts of wheel loads that each act on a corresponding one of a plurality of wheels supporting the rigid body. A wheel load estimation unit estimates the wheel loads.

An object responsive control system for a work machine having a boom, an attachment pivotally coupled to the boom, an object sensor adapted for sensing the presence of an undesirable object located in a travel path of the work machine and delivering an object signal upon sensing the undesirable object. A controller adapted for receiving a boom position signal, an attachment position signal, and calculating an elevational position based on the boom position signal. The system activating an object response upon calculating an attachment elevation position above a predetermined threshold and receiving an object signal.

A forklift includes a cabin and a seat for use by a driver arranged in the cabin. The cabin has a lateral opening to enter and exit the cabin, and the seat is mounted rotatably relative to the cabin. There is a safety bracket for preventing the driver from involuntarily exiting the cabin through the lateral opening, and for providing lateral impact protection. The safety bracket is mechanically connected to the seat to be rotatable together with the seat.

A proximity detection and collision avoidance system determines whether a collision risk exists between two vehicles by measuring magnetic field vectors generated on each of the vehicles as the relative distance between the vehicles decreases.

A materials handling vehicle comprises an operator compartment, a compartment tower, a multi-field scanning tool, and mechanisms that facilitate movement along a travel plane in a warehouse. The tool establishes a scan field, and, within scan field bounds, an occupancy detection field and an obstacle detection field. Tool scanning hardware is configured to generate the scan field from a point of origin that is elevated relative to the operator compartment and to expand the scan field such that it intersects the operator compartment and extends laterally beyond lateral edges of the operator compartment such that the occupancy detection field falls within the operator compartment, the obstacle detection field falls outside of the operator compartment, and the multi-field scanning tool is configured to indicate the presence of an occupant in the occupancy detection field and obstacles in the obstacle detection field.
