Systems and methods include an integrated display having a graphical user interface that combines aspects of a telematic system with a vehicle control system. The integrated display combines a touch screen and a manual input keypad. Using both the touch screen's graphical user interface and the keypad, the integrated display can operate in multiple operation modes, including a touch mode where the operator controls the graphical user interface functions by touching predefined areas or tiles on the screen, and a keypad mode, where the operator controls the graphical user interface functions by touching keys on the manual input keypad. The integrated display can be controlled in a mixed mode operation, where the operator can control the graphical user interface functions using both the touch screen (touch mode) and the manual input keypad (keypad mode) to complete data entry processes, for example, and the integrated display can automatically transition between modes.

A system for controlling an industrial truck with a drive portion including a traction drive portion, a steering portion, and a load portion, comprises a portable transmitting unit configured to be positioned away from the industrial truck. The system further comprises at least three transmitting and receiving units positioned in a predetermined spatial arrangement with respect to one another on the drive portion. An evaluation unit is provided that is configured to determine a position of the portable transmitting and receiving unit relative to the industrial truck by measuring signal propagation times. The industrial truck further comprises a control unit configured to send a control command for traction drive and/or steering if the relative position of the portable transmitting and receiving unit is located within a predetermined spatial region relative to the industrial truck.

Provided is a proximity detection system which is capable of changing a level of alarm depending on a distance between a worker and an apparatus, and setting an alarm-generating distance in an apparatus-side unit. The proximity detection system comprises a magnetic field detecting function-equipped RFID tag attachable to a worker, and a distance detection control unit installable in a self-propelled apparatus. The magnetic field detecting function-equipped RFID tag is configured to be selectively set between a plurality of levels of magnetic field detecting sensitivity, and comprises means to intermittently transmit setup magnetic field detecting sensitivity data and magnetic field detection data. The distance detection control unit is configured to output different levels of alarm according to the data received from the RFID tag.

Systems and methods for collision avoidance include a plurality of sensors respectively disposed on a plurality of movable objects, wherein each sensor is configured to transmit signals indicating the location of the movable object. The system further includes a receiver configured to receive the transmitted signals and a controller in communication with the receiver. The controller is configured to monitor the received signals from the plurality of sensors indicating the locations of the movable objects to determine a direction of travel of each movable object based on locations of the movable objects over time. The controller is further configured to determine an intersection region of the direction of travel of at least two movable objects and generate an output signal to provide an alert at the intersection region of the at least two movable objects, when at least one movable object is within a predetermined proximity of the intersection region.

A materials handling vehicle is provided comprising: a support structure including a first member; a movable assembly coupled to the support structure; a hydraulic system; and a control system. The support structure further comprises lift apparatus to effect movement of the movable assembly relative to the support structure first member. The lift apparatus includes at least one ram/cylinder assembly. The hydraulic system includes a motor, a pump coupled to the motor to supply a pressurized fluid to the at least one ram/cylinder assembly, and at least one electronically controlled valve associated with the ram/cylinder assembly. The control structure may estimate a speed of the movable assembly from a speed of the motor and may control the operation of the at least one valve using a comparison involving the estimated movable assembly speed and a determined speed, and the comparison may not involve use of an operator commanded speed.

A work vehicle includes a frame assembly and an attachment assembly. The attachment assembly has an attachment end pivotally connected to the frame assembly and a distal end configured for receiving a variable load. At least one force sensor senses at least one force associated with the attachment end. The at least one force sensor provides an output signal representing the sensed at least one force. An inclination sensor senses an inclination associated with the frame assembly and provides an output signal representing the sensed inclination. An electrical processing circuit is configured for receiving the output signal from the at least one force sensor, determining a value of a couple at the frame assembly which is associated with the sensed at least one force, comparing the couple with a threshold value which is dependent on the sensed inclination, and controlling the controllable output dependent on the comparison.

A lifting device of an industrial truck includes a load handling arrangement that is raised and lowered on a lifting frame and a hydraulic lift cylinder device that is actuated by an electrically actuatable control valve device, in which an electronic control device is provided to actuate the control valve device. The electronic control device has an automated set-down mode actuated during a lowering of the load handling arrangement. The load is lowered at a lowering speed specified by a deflection of a control element to the designated surface. As the control element continues to be deflected into the lowering position, the lowering of the load handling arrangement is terminated by the electronic control device by actuating the control valve device into a shut-off position to prevent the load handling arrangement from being set down on the designated surface.

Systems and methods to detect and warn proximate entities of interest are described herein. An example method for assessing a possibility of a collision between entities of interest, each having their own characteristics of movement, includes sampling movement of each entity at least two points in time, generating a trajectory vector for each entity based on the movement sampling, expanding the trajectory vector of each entity based on at least one characteristic of movement of that entity, and analyzing the expanded trajectory vector of each entity for overlap to assess a possibility of a collision between the entities of interest.

A system includes a detection device configured to transmit and receive one or more signals in a generally vertical direction above a vehicle. Additionally, the system may include a processing device configured to measure a time of flight associated with the transmission and receipt of the one or more signals in the generally vertical direction. A distance travelled by the one or more signals may be determined based, at least in part, on the measured time of flight, and the distance travelled may be compared with a threshold distance to determine an overhead clearance of the vehicle. In response to determining the overhead clearance, a vehicle system may be activated.

The present disclosure relates to a forklift and a forklift control method. The forklift and the forklift control method according to the present disclosure may adjust a fork/mast inclination with reference to the coefficient of friction, and precedently and appropriately adjust a fork/mast inclination right before the forklift enters or exits from a slope by referring to geological information. Further, when a degree of danger is not decreased even when a fork/mast inclination is tilted backward to the largest extend, the forklift and the forklift control method according to the present disclosure may decrease a travelling speed of a vehicle by decreasing an output of the forklift or operating a brake, thereby remarkably decreasing the danger of the load falling.
