摘要： A materials handling vehicle technology monitor receives wirelessly, from a fleet of materials handling vehicles, electronic vehicle records. Each electronic vehicle record includes technology feature data recorded by a controller on an associated materials handling vehicle. Typically, the electronic vehicle record is generated in response to a corresponding technology feature on the materials handling vehicle being operated in a work environment. Moreover, each electronic vehicle record includes an operator identification of an operator of the materials handling vehicle at the time the technology feature data is recorded. The monitor also generates for each operator, an electronic measurement based upon a comparison of expected technology feature usage, e.g., a threshold, compared to the technology feature data in the received electronic vehicle records, which are associated with the corresponding operator. The process further comprises outputting to a dashboard, a graphical representation of the generated measurements.

摘要： Testing operational characteristics of a remote control device associated with a materials handling vehicle can include waiting for receipt of a first input indicative that a first button of the remote control device has been pressed, wherein the first button comprises a travel button of the remote control device. The testing may further comprise waiting for receipt, subsequent to receiving the first input, of a second input indicative that at least a second button of the remote control device has been pressed, wherein the second button relates to a first auxiliary vehicle function. The testing still further comprises determining whether or not a predetermined button pressing sequence is successful based at least in part on receiving or not receiving the first and second inputs; and optionally driving a display on the vehicle to provide a visual indication that the button pressing sequence is successful or not successful based on the determination.

摘要： A materials handling vehicle comprising a hitch system, and a drive mechanism. The hitch system comprises a hitch and a hitch controller. The hitch comprises a latch, one or more sensors, an actuator, and a receiving member. The latch is positionable between open and closed positions. The actuator is positionable between retracted, intermediate, and extended positions. The receiving member is configured to lead a cart hook to engage the latch when in the closed position. The one or more sensors are configured to detect a position of the latch and a presence of the cart hook received within the receiving member. The hitch controller is configured to position the actuator in one of the retracted position, the intermediate position, and the extended position, and to position the latch in one of the open position and the closed position in response to signals received from the one or more sensors.

摘要： A method for operating a materials handling vehicle is provided comprising: monitoring, by a controller, a first vehicle drive parameter corresponding to a first direction of travel of the vehicle during a first manual operation of the vehicle by an operator and concurrently monitoring, by the controller, a second vehicle drive parameter corresponding to a second direction different from the first direction of travel during the first manual operation of the vehicle by an operator. The controller receives, after the first manual operation of the vehicle, a request to implement a first semi-automated driving operation. Based on the first and second monitored vehicle drive parameters during the first manual operation, the controller controls implementation of the first semi-automated driving operation.

摘要： A processing device having a graphical user interface includes a touch screen display that receives touch gesture commands from a vehicle operator and a controller. In operation, computer code implements a set of widgets such that at least one widget is normally viewable on the touch screen display. The set of widgets are organized to include at least one home screen, such as a motion home screen that displays at least one travel related widget, a lift home screen that displays at least one lift related widget, etc. When a current operating state of a control module of the industrial vehicle indicates that a designated control is engaged, the controller causes the display to snap to the associated home screen position.

摘要： A materials handling vehicle including a vehicle-side charging contact assembly coupled to a battery, a steerable drive wheel defining a drive wheel track width W, and a pair of load wheels defining a load wheel gap G between the pair of load wheels that is larger than the drive wheel track width W. A charging station includes a pair of floor-side charging contacts configured to transfer charging current to the vehicle-side charging contact assembly. The pair of floor-side charging contacts define an inner contact spacing S1 that is larger than the drive wheel track width W, and an outer contact spacing S2 that is larger than the inner contact spacing S1 and smaller than the load wheel gap G to permit passage of the steerable drive wheel between the floor-side charging contacts, followed by passage of the pair of load wheels outside of the floor-side charging contacts.
