[0004] not applicable Technical Field

[0005] This invention relates to the field of material handling vehicles, and more specifically to a touch screen display and keypad that includes multiple operating modes and integrates a telematics system with a vehicle control system. Background Technology

[0006] Material handling vehicles are designed with different configurations to accomplish a variety of tasks. These types of vehicles are commonly used in warehouses and factories to transport, store, and recycle materials and finished products.

[0007] In warehousing operations, material quantities and inventory turnover rates grow rapidly. Therefore, to remain competitive, it is crucial for warehousing operations to ensure that every piece of equipment and every employee is efficient. Recent research indicates that, in fact, 70-80% of the costs associated with owning and operating material handling vehicles are attributable to labor. For warehouses competing on a global scale, continuously improving operator productivity is key to cost reduction. To achieve these goals, warehouse management systems are frequently used, among other things, to automatically detect and wirelessly transmit data to and from material handling vehicles, as well as monitor operator efficiency. Within these warehouse management systems, a central computer system can be used to monitor inventory flow, the maintenance status of the industrial vehicle fleet, operator performance parameters, and vehicle parameters.

[0008] To provide these telemetry capabilities, wiring harnesses and sensors are typically added to vehicles in a fleet of post-manufacturing material handling vehicles. These harnesses connect sensors and other devices to the system and add numerous connection points within the vehicle. Due to the large number of connection points, these additional systems can malfunction.

[0009] What's needed is a warehouse management system that can view the efficiency of the vehicle fleet and determine when operational changes are required. These changes include scheduling material handling vehicles to appropriate locations, acquiring additional material handling vehicles, and identifying the different types of material handling vehicles needed.

[0010] A further need is to provide truck operators with the most efficient way to use their trucks, delivering operator and vehicle data to them. In some solutions, there can be multiple truck operator displays showing different types of data. One display can be integrated with a warehouse management system, which can be an add-on system. Another display can be built into the vehicle, typically indicating vehicle-related operational data such as battery life and weight on the forks. Multiple displays not only reduce vehicle operating efficiency for the operator, but the systems driving these displays also cannot be well integrated, forcing the operator to understand the operation and function of multiple systems and related displays. A display device is needed that addresses the problems of existing vehicle display systems. Summary of the Invention

[0011] Embodiments of the present invention overcome the deficiencies of existing systems and methods by providing an integrated display with a full-featured graphical user interface (GUI), which combines multiple aspects of a telematics system and a vehicle control system.

The term "memory" may also include other known types or future-developed memories or combinations thereof.

[0064] As used herein, various aspects of the invention will be described in conjunction with an integrated display structure on a material handling vehicle, the integrated display having multiple operating modes. It is precisely these features and advantages that make embodiments of the invention highly suitable for this purpose. However, it should be understood that various aspects of the invention can be applied to other vehicles and to achieve other objectives.

[0065] Now refer to the attached diagram, and especially Figure 1 ,exist Figure 1 An embodiment of a material handling vehicle 10 is shown, which may include embodiments of the present invention. The embodiment illustrates a material handling vehicle 10, such as a lift truck, and includes an operator's compartment 17 with an opening 19 for operator entry and exit. The operator's compartment 17 may include a control handle 14. Figure 2 ), integrated display 55 ( Figure 2 and 9 ), and a "deadman" switch 20 located on floor 21. No motor on the material handling vehicle can be operated until the "deadman" switch 20 is turned off by the operator's foot. Steering wheel 16 ( Figure 2 It can also be installed in the operator's compartment 17. The antenna 75 for wireless communication with the external warehouse system can be coupled to the material handling vehicle, and, as described more fully below, is connected to the internal vehicle controller 12. Figure 2 ), to provide bidirectional communication from vehicle controller 12 to warehouse system.

[0066] The material handling vehicle 10 shown is an upright forklift. It should be understood that material handling vehicles are designed with different configurations to perform a variety of tasks. For example, while vehicle 10 is shown as an upright forklift, it will be apparent to those skilled in the art that the embodiment is not limited to this type of vehicle and can be configured with a variety of other types of vehicles, including, for example, cars, vans, trucks, flatbed trucks, forklifts, front and rear stand-up operator cranes, handcarts, high-lift trucks, counterbalance forklifts, swing-up trucks, as non-limiting examples. The integrated display 55 is suitable for driver-controlled, pedestrian-controlled, and remotely controlled (AGV) material handling vehicles, as well as other powered vehicles used in warehouses or plants for transporting, storing, and retrieving goods.

[0067] Reference Figure 2The material handling vehicle includes a vehicle controller 12 that receives operator input signals and, based on the received signals, provides command signals to each lift motor controller 23 and drive system 25, which includes a traction motor controller 27 and a steering motor controller 29. The drive system 25 provides power to drive the material handling vehicle in a selected direction, while the lift motor controllers 23 drive the forks 31 to raise or lower the load 35 along the support 33, as described below. The material handling vehicle and vehicle controller 12 can be powered by one or more batteries 37 coupled to the vehicle controller 12, drive system 25, steering motor controller 29, and lift motor controller 23 via fuses or circuit breakers 39.

[0068] Operator inputs include a key switch 18, a "stop" switch 20, a steering wheel 16, an operator control handle 14, and an integrated display 55. The key switch 18 is activated to apply power to the vehicle controller 12, thus starting the material handling vehicle. The "stop" switch 20 provides a signal to the vehicle controller 12 to operate the brake 22, providing a "stop" braking device that prevents the vehicle from moving unless the "stop" switch 20 is activated by the operator. The lift motor 51 or steering motor 47 can only be operated after the "stop" switch 20 has been turned off.

[0069] The operator control handle 14 provides a travel request signal to the vehicle controller 12. Normally, the handle 14 rotates in the vertical plane to provide commands for the travel direction and speed of the material handling vehicle. A four-way switch 15 located on the top of the handle 14 provides tilt-up / down functionality when activated in the forward and backward directions, and right / left shift functionality when activated in the right and left directions. Multiple control actuators 41 located on the handle 14 can provide additional functions and may include, for example, an arrival button, a retraction button, and a horn button, as well as a potentiometer providing a lifting function. Many other functions may also be provided, depending on the material handling vehicle's structure and intended use.

[0070] A traction motor controller 27 drives one or more traction motors 43 to provide power to the forklift, the traction motors 43 being connected to wheels 45. The speed and direction of the traction motors 43, and the associated wheels, are selected by the operator via an operator control handle 14. Vehicle speed and direction are typically monitored and controlled via speed and distance signals provided by a rotation sensor 44, which may be an encoder or other feedback device coupled to the traction motors 43, and these signals can provide feedback to determine the distance traveled by the material handling vehicle. The wheels 45 are also connected via the traction motors 43 to friction brakes 22 for servicing and parking braking functions for the material handling vehicle. The friction brake 22 may be a spring-loaded brake, which defaults to a "brake on" state, thus enabling switch 20 and the associated brake 22 to provide a "stop" braking function. The operator must provide a signal indicating that the "stop" brake is released to drive the truck, as described above, here provided by the "stop" switch 20. The traction motors 43 are typically electric motors, and the associated friction brakes 22 may be electrically or hydraulically operated. Although a friction brake 22, a traction motor 43, and a wheel 45 are shown, a material handling vehicle may include one or more of the aforementioned elements.

[0071] As described above, in the direction selected by the operator by turning the steering wheel 16, the steering motor controller 29 is connected to drive the steering motor 47 and the associated steering wheel 49. The direction of rotation of the steering wheel 49 determines the direction of movement of the material handling vehicle.

[0072] The lift motor controller 23 provides command signals to control the lift motor 51, which is connected to a hydraulic circuit 53 for driving the fork 31 along the support 33, thus moving the load 35 up or down, depending on the direction selected by the control handle 14. In some applications, the mast 33 may be a telescopic mast. Here, an additional hydraulic circuit is provided to raise or lower the mast 33 and the fork 31. As shown here, a height sensor 59 is provided in the mast control system to provide a signal to the vehicle controller 12 indicating the height of the mast 33. The height sensor 59 may be, for example, an encoder, a flow sensor in the hydraulic system, a beam, or other type of sensor. Similarly, a weight sensor 57 is provided on the fork 31. The weight sensor 57 may be, for example, a load cell, a strain gauge, a beam, or a pressure sensor in the lift system, and provides a signal to the controller 12 indicating whether the load is on the fork and the weight of the load.

[0073] In addition to providing control signals to the drive system and lift control system, the vehicle controller 12 can also provide data to an integrated display 55, which provides information to the operator. The information displayed on the integrated display 55 may include, for example, the weight of the cargo tray or load located on the fork 31, the vehicle speed, time, or maintenance information. Although not shown here, temperature sensors may also be included to monitor the temperature of the motor and other components. A variety of other information may also be displayed, such as the number of cargo trays moved, the number of cargo trays moved over a period of time, and the average number of cargo trays moved by the vehicle, as non-limiting examples.

[0074] The integrated display 55 allows the operator to use the touchscreen 122 and the manual input keypad 124. Figure 9 and 10 The input data can be used alone or in combination, as described in more detail below. Data input via the integrated display 55 allows operators, administrators, or other personnel to input data into the vehicle controller 12, and can be implemented as a touchscreen 122, a manual input keypad 124, while in other embodiments, a keyboard, a series of input keys, a mouse, a joystick, and / or other input devices can be integrated into the integrated display 55.

[0075] In addition to inputting data using a touchscreen and manual input keypad, several other data input and output devices can be connected to the vehicle controller 12, including, for example, an inventory scanning device 65, vehicle sensors 66 for parameters (e.g., temperature), and a communication port 69. The inventory scanning device 65 can be, for example, a barcode reader, a radio frequency identification (RFID) reader, a data input pad, a RuBee.TM. or other IEEE P1902.1 standard reader, or other devices capable of reading corresponding identifiers (e.g., RFID tags, IEEE P1902.1 tags, barcodes, or symbols associated with pallets or other loads).

[0076] Communication port 69 is connected to warehouse communication interface 71, which can be installed on a material handling vehicle and connected to battery 37 of the vehicle's electrical system. Warehouse communication interface 71 includes circuitry 73 and antenna 75 for bidirectional wireless communication with a communication system in the warehouse using any known protocol.

[0077] Now refer to Figure 3-5The communication port 69 can be located in the wiring harness of truck 10, close to the housing for vehicle controller 12. Communication interface 71 may include a mating connector that can be directly connected to communication port 69. As shown here, an additional junction box can also be connected to provide power to battery 37. However, it should be understood that battery power can also be routed directly through communication port 69. Communication interface 71 can establish a bidirectional communication link with vehicle controller 12 through communication port 69. This link allows sensor data, operational status data, and switch and control status data to be sent from vehicle controller 12 to external devices. Furthermore, since communication interface 71 is directly connected to vehicle controller 12, command signals from external devices can be applied to the vehicle, enabling signals to limit vehicle speed, limit acceleration, provide data to the integrated display 55, lock the vehicle, and control other vehicle functions, such as...

[0078] Although communication port 69 and the associated communication interface 71 are shown herein, it should be understood that information from the warehouse management system can be sent directly to and from vehicle controller 12. In some embodiments, however, the standard RS-232 communication protocol can be used to provide information to or from vehicle controller 12, thus enabling the use of different communication interfaces 71 with vehicle 10 and the warehouse computer system. By providing simple connectivity and standard protocols, prior art systems and methods are suitable for use with multiple different warehouse systems.

[0079] Refer again Figure 2 The vehicle controller 12 can store data regarding the operation of the material handling vehicle. This data may include the amount of operation time, the battery's state of charge (BSOC), and encountered fault codes, for example. The operation time can be calculated based on the duration the "stop" switch 20 is pressed, referred to as the "stop time." Alternatively, the operation time can be the time the key switch 18 is turned off, the lifting motor 51 is activated, or the material handling vehicle 10 is moving based on feedback from a rotation sensor 44 connected to a traction motor 43. Furthermore, the activation time of the lifting motor 51 can be used to monitor lifting operations. Various speed parameters, such as the speed and acceleration of the vehicle and mast 33, can also be monitored. Vehicle operation data can be acquired and stored in a memory or other storage device within the vehicle controller 12.

[0080] Vehicle operation data may also include operator identifiers, such as names or employee numbers, which can be entered via an integrated display 55 connected to the vehicle controller 12. Furthermore, daily operator lists can be presented to the operator on the integrated display 55. Data obtained from these lists can be correlated with the operator along with data related to individual driving performance. For example, average vehicle acceleration and data, as well as collision data, the number of pallets moved, or other data useful for monitoring operator performance, productivity, and efficiency can be monitored. The operator can respond to the list items using any input mode on the integrated display 55.

[0081] Now refer to Figure 6 A vehicle information system 100 is provided for one or more warehouses 101 in which material handling vehicles 10 operate. The invention is described in the case of an exemplary company having a facility in the form of three warehouses. Each warehouse 101 includes a communication system 102 that connects the vehicles therein to a central warehouse computer system 104. The communication system 102 has multiple wireless access points 106 distributed throughout the warehouses 101, for example, at loading docks and goods storage areas. The central warehouse computer system 104 communicates with the wireless access points 106 via communication links 105, shown as a hardwired local area network; however, the communication links can be implemented as connections via the Internet, Wi-Fi systems, or other wireless links.

[0082] Reference Figure 7 The warehouse computer system 104 includes a processor 80 capable of executing program instructions stored in memory 82, which forms part of a storage section 83. The processor 80 may be a commercially available device designed to use commercially available operations, for example. It may include internal memory and I / O controllers for system integration and overall memory management circuitry for handling all external memory 82. The processor 80 may also include a bus driver providing a direct interface with a multi-bit bus 84.

[0083] Bus 84 may be an industry-standard bus that transmits data between processor 80 and multiple peripheral controller modules. These may include disk controller 85, which provides high-speed data transfer to and from CD-ROM drive 86 and disk drive 87 (or other known storage devices). Graphics controller 89 may be coupled to monitor 90 via standard video connector 92, and keyboard and mouse controller 88 may receive data manually entered via keyboard 91 and mouse 93. Keyboard 91 and mouse 93 are both “user input devices” through which a person interacts with the computer system. Warehouse computer system 104 may include printer 95 coupled to bus 84 via printer interface 94, thereby enabling the printing of reports and monitoring screen displays in hard copy form. When appropriate software is executed, graphics controller 89, monitor 90, and processor 80 are considered to constitute a report generator. Bus 84 is also connected to a communication system interface 96, which is connected to a wireless access point 106, and a network interface 98, which can be used to couple the warehouse computer system 104 to a wide area network, such as the Internet.

[0084] return Figure 6 For the purposes of this invention, the warehouse management computer system 114, located at the headquarters of the warehouse company, can be described similarly to that of the warehouse computer system 104. Therefore, both the warehouse computer system 104 and the headquarters computer system 114 can execute the same software to analyze and report the operational information of material handling vehicles.

[0085] Warehouse computer system 104 can be connected to a wide area network (WAN), which may be Internet link 108 as shown herein, or other types of wired or wireless networks. Through Internet link 108, warehouse computer system 104 can connect to database 110, which stores vehicle-specific data provided by the manufacturer through manufacturer computer system 112. The selected data can also be accessed, for example, by warehouse managers or vehicle dealers who can connect to database 110 via Internet link 108.

[0086] Data belonging to a specific vehicle stored in database 110 can be accessed using the vehicle serial number, and detailed data may include, for example, truck documentation and parts & service manuals; field repair reports and other information; Bill of Materials (BOM) creation; add options (truck modification history); create performance information (QAP); service history (parts, labor, technical observations); operation history (collisions, timers, fault codes, lifespan); usage / maintenance history (timers, fault codes, BSOC); sales / resale history; service end date, etc. The model number can be used to access basic information about material handling vehicles of that type, such as parts & service manuals.

[0087] Reference Figure 2 and 6 Communication interface 71 and antenna 75 can be used to wirelessly transmit vehicle data (including, for example, serial number, operator identifier, and vehicle operation data) from the vehicle to communication system 102. The information is received by communication system 102, which transmits the serial number and operation data to warehouse computer system 104. These wireless transmissions can occur continuously while the vehicle is running, within defined time intervals, or when a given event (e.g., end of shift or malfunction) occurs. Information collected from each vehicle 10 can then be relayed inter- or inter-regional to database 110 via internet link 108, and can also be sent to computer system 114 at the warehouse company headquarters.

[0088] Due to the bidirectional communication between the vehicle controller 12 and the warehouse communication system 102, the warehouse communication system 102 can also control the operating parameters of the material handling vehicles. Specifically, the system can control the maximum speed and acceleration of the trucks in the forward and backward travel directions. Other vehicle functions, such as the horn, can also be activated by the warehouse computer system 104 as an alarm when certain operating conditions are detected.

[0089] Therefore, for example, a warehouse control system can correlate the workload of a vehicle with the level of wear experienced by critical components. For instance, if a temperature sensor indicates that a component temperature is rising at a higher rate than expected, but the overall productivity level is not excessive, it can be inferred that the operator is using the truck to its limit for a period of time before leaving it idle. To prevent the vehicle from overheating, the warehouse communication system can limit the truck's acceleration and maximum speed. Truck operating parameters, such as speed and acceleration, can also be limited to control the vehicle's energy consumption and promote the use of "green" trucks.

[0090] Similarly, if the battery's state of charge is low and nearing the end of a shift, the warehouse communication system can limit the vehicle's acceleration and maximum speed to delay the battery's charging needs. Based on inventory data, if the "fragility" of the load is known, the vehicle's acceleration and speed can also be limited accordingly. In taxi fleets, truck operating parameters can be restricted when payment is not received on time.

[0091] Furthermore, vehicle control can be used to "zone" vehicles. Using location-based input data, such as via wireless access point 106, GPS receiver 68, beacons installed at specific locations, or other inputs, virtual geographic areas can be defined for vehicles in use to ensure they follow predetermined routes. Notifications with time, date, and location markers can be recorded by the warehouse control system when designated boundaries intersect. Additionally, the warehouse computer system can shut down vehicles or limit maximum speed and acceleration when boundary lines intersect. An integrated display 55 in the vehicle can also be used to provide instructions to the operator when approaching or crossing a boundary. The system can be used to help prevent excessively tall trucks from entering areas with low ceilings or door heights, to keep non-compliant material handling vehicles outside areas requiring EE-rated battery-powered vehicles (as defined in Underwriters Laboratories standard UL583), or to keep non-compliant material handling vehicles outside refrigerated areas, as a non-limiting example.

[0092] Similarly, vehicle acceleration and speed can be limited based on operator feedback. During operator training, the warehouse computer system 104 can restrict the speed or other functions of vehicles logged in by such operators.

[0093] The warehouse computer system 104 can also provide signals to lock trucks, rendering them completely unusable. For example, when a truck requires service, it can be locked in a disconnected position until it is started by an authorized service personnel.

[0094] Since the integrated display 55 is accessible within vehicle 10, it can also be used by the warehouse system. For example, warehouse service reports can be sent to the integrated display 55. As described above, the vehicle can also be locked in place when service is required, intentionally restricting vehicle operation to guide service execution. The vehicle controller 12 can then send a report indicating that service has been completed. The vehicle controller 12 can also track the time required for maintenance and send information that maintenance has been completed, thus providing a means for tracking the efficiency and effectiveness of service and maintenance operations.

[0095] Additionally, messages can be sent from the warehouse computer system 104 to the integrated display 55 to alert the operator to conditions in the warehouse / plant, such as spills in aisles. This information can also be linked to alarms, such as fire or chemical release alarms. The operator may have to perform an action, such as pressing a dynamic tile on the touchscreen 122 or an available button on the keypad 124, to confirm receipt of the information. Paging messages, news summaries, and other information can also be written from the warehouse communication system or from another computer connected to the warehouse communication system to the integrated display 55 in the vehicle.

[0096] Similarly, when a software update is required, based on data in database 110, the update can be sent to the entire vehicle fleet, or only to those vehicles with a specific version of the software. Furthermore, the warehouse computer system can be used to configure or reconfigure the software in selected vehicles 10 or the fleet of vehicles 10.

[0097] Other commands can be transmitted from the warehouse computer system 104 to the vehicles. For example, maintenance commands can be set individually for each vehicle or performed simultaneously on all vehicles. When maintenance is complete, the vehicle controller 12 can send a message back to the warehouse computer system to reset the maintenance clock.

[0098] Additionally, a dedicated actuator or button on the vehicle, or an existing actuator such as a horn button, can be dedicated by the vehicle controller to providing a signal to the warehouse computer system 104 to activate another function, such as opening a lift door, refrigerator entrance, or other device. Here, it is preferable to combine the function and device in a way that associates the vehicle's location with the activation device. Thus, for example, the lift door can be activated when the signal length of the wireless device indicates that the vehicle 10 is near the lift door and the actuator is engaged.

[0099] This invention can also provide a variety of other functions. For example, when the warehouse computer system determines that a vehicle has stopped operating, or may stop operating due to detected problems or vehicle charging needs, critical tasks can be reassigned to other vehicles in the fleet, thus improving efficiency and limiting downtime.

[0100] The vehicle information system 100 can also determine, based on factors such as operating parameters, driver skill, and material handling dynamics, which vehicles in the fleet operate at a higher level of efficiency than others. Some types of material handling vehicles perform better in horizontal transport, while others excel at loading or unloading loads. Some are better suited for both high- and low-level picking operations. In a given warehouse, the dynamic demand for moving materials can change hourly. The calculation system can assign or reassign vehicles to certain tasks and improve productivity as the situation evolves.

[0101] Another benefit of collecting operational data from multiple material handling vehicles 10 operating in warehouse 101 is that the data can be compiled in various ways to provide warehouse management with useful reports, charts, and tables showing current vehicle usage and future demand. This compilation can be performed by a vehicle information reporting system implemented by software executed by warehouse management computer system 114 or warehouse computer system 104, depending on the location of the warehouse manager. This allows managers in a specific warehouse 101 to view the operation of material handling vehicles in that facility, and also allows corporate executives at headquarters to analyze the operation of material handling vehicles across the entire company. In some embodiments, designated personnel can access the vehicle information system using, for example, a designated username and password, and each designated person's access can be limited to certain parts of the system. For example, a manager in one warehouse might be limited to viewing data and reports activated only in that specific warehouse, while an executive at warehouse headquarters could access information about all facilities within the warehouse company. In another example, vehicle maintenance personnel could access vehicle performance information, but not information about vehicle operators. Company management can set policies regarding employee types who can request certain types of information.

[0102] Reference Figure 8 The vehicle information reporting system can store user information 118 for each person with access rights. In addition to specifying the individual's username, password, and access level, the user information may also include configuration information that the relevant user can set. This configuration information specifies certain parameter selections for a particular user, such as the data format and type in different types of reporting modes.

[0103] The vehicle information reporting system can process and interactively display collected vehicle information using graphs and charts showing actual performance and predicted trends based on said performance. Unrestricted users can filter the data to display data from all or selected company facilities, the type of material handling vehicle, the type of vehicle event, and operator performance. Users can browse and checklist-type menus through the display panel using different display formats. Furthermore, an overview display mode provides a concise understanding of the operational status of material handling vehicles over a selected time period, enabling brief comparisons of vehicle operations across different facilities and different types of material handling vehicles. The system can provide trend information that can be used by managers to predict future material handling vehicle demand. For example, a trend graph can show the point at which fleet usage increases to the point where additional vehicles are needed.

[0104] It should be understood that warehouse computer system 104, manufacturer computer system 112, and distributor computer system 116 are also capable of executing information reporting systems; however, the specific types of data that these other computer systems can access may be limited by the configuration of the selected software. For example, the operation of warehouse computer system 104 may be limited to information about the relevant warehouse that the company can access, and the manufacturer and distributor computer systems may be restricted to accessing proprietary information of the warehouse company and its employees.

[0105] To gain a full understanding of the capabilities of the integrated display, the integrated display 55 and its various operating modes will be described in more detail below.

[0106] Now go to Figure 9 An integrated display 55 according to an embodiment of the present invention is shown. Figure 9 The illustrated embodiment shows that the integrated display 55 can be integrated with the main body of the vehicle 10, such as the dashboard 120 of a material handling vehicle 10, to enable efficient visual access and data input for the vehicle operator. The illustrated integrated display 55 includes a touchscreen assembly 122 and a manual input keypad 124. The integrated display 55 can receive power from a battery 37, or alternatively, it can receive power from a different source.

[0107] Reference Figure 10 The touchscreen 122 and manual input keypad 124 can be housed within a display housing 128. The display housing 128 can be customized and configured to be installed in a predetermined opening in the dashboard 120. It should be understood that the size and shape of the housing 128 and the corresponding opening in the dashboard 120 can be of any shape to allow the integrated display to be installed in the dashboard 120 or elsewhere on the vehicle 10. It should be understood that more than one housing may be included. Therefore, the integrated display 55 with the touchscreen 122 and manual input keypad 124 facilitates accessibility, visibility, and data input and retrieval. The integrated display 55 allows the operator to control the vehicle at any time.

[0108] When installed in the dashboard 120 of vehicle 10, the integrated display 55 reduces components near the front of vehicle 10, thus providing a more streamlined design. The integrated display 55 also provides a touchscreen 122, which includes a graphical user interface 130. The graphical user interface 130 may include controls easily performed by an operator's fingers or hand and may be integrated with a manual input keypad 124, which may be located near the touchscreen 122. In some embodiments, the manual input keypad 124 may be a standard five-way keypad, including up, down, left, and right buttons, and input buttons 126. It should be understood that other configurations are also conceivable and will be understood by those skilled in the art.

[0109] Reference Figure 11 In other embodiments, the integrated display 55 may be a separate integrated display 134, which can be mounted separately to the vehicle 10 using a mounting bracket (not shown). The mounting bracket provides flexibility in mounting location and allows the integrated display 134 to be pivoted or pivoted to one side or the other side of the forklift 10, so that the operator can view and control the features on the integrated display unit 134 according to the operator's preferences.

[0110] The integrated display 55 can be configured to display various information, including but not limited to data and functional information about vehicle 10, warehouse management system applications, and fleet management information. As some examples, data and functional information about vehicle 10 may include vehicle speed, battery power, maintenance time, etc. Warehouse management system applications may include displaying orders for certain items and the location of those items. Fleet management information may include statistics on all vehicles 10 forming part of a fleet, such as the total number and location of all vehicles, the number of vehicles currently in use, and the time each vehicle has been used within a specified time period. Because the integrated display 55 can display information about vehicle 10 functionality, warehouse management system applications, and fleet management information in a single unit 55, this information is accessed efficiently and more quickly than if the information were displayed on multiple display units at different locations on vehicle 10.

[0111] Additionally, the integrated display 55 can provide a navigation module interface, where sensing and situational awareness inputs, as well as control inputs (e.g., throttle, brake, and steering), are all transmitted through a common interface. Sensing and situational awareness inputs may include information obtained from devices such as positioning device 136, which allows vehicle 10 to be used as an AGV, or from other devices configured on vehicle 10 that provide feedback on certain aspects of the vehicle or its environment. In some cases, the integrated display 55 can be programmed to display inputs and messages based on received inputs. Since the integrated display 55 can provide a common interface for sensing and situational awareness inputs and control inputs, it can also be programmed, if applicable, to prioritize outputs and messages displayed on the graphical user interface 130. Other interface modules are also conceivable, including, for example, wireless communication modules for Wi-Fi and / or cellular; USB modules; and universal card reader modules, as non-limiting examples.

[0112] Reference Figure 12 and 13 ,exist Figure 12An exemplary "run screen" of the graphical user interface 130 on the touchscreen 122 is shown. The graphical user interface can provide an intuitive and simple interface including multiple dynamic tiles 140, where data is displayed on the tiles in real time, such as... Figure 12 As shown. The graphical user interface 130 can provide multiple individual and nested levels of depth for exploration. In some embodiments, the graphical user interface 130 can be operator-customized to allow operators or fleet managers, for example, to customize each screen that can be displayed on the graphical user interface 130.

[0113] As a limiting example, the "Menu" button 142 can open a nested screen. The Battery State of Charge (BSOC) button 144 can provide an indication of the battery charging current. The speed indicator 146 can display the vehicle speed. The weight on the fork tile 150 can display the weight of the load currently carried by the vehicle. In some embodiments, these tiles can be read-only tiles without navigation points. Tile 152 can display the current state of the fork, with a certain amount of extension or full retraction, for example.

[0114] Reference Figure 13 Message tile 154 can serve as a communication tool between warehouse managers and each vehicle (individually or across a large fleet). A message icon 156 can appear when a new message is received. Selecting the message icon on the screen displays a message list. Once an activation code or alert exists, an "Alert / Code" icon 158 appears. Selecting the "Alert / Code" button 160 displays the activated alert / warning.

[0115] The dynamic tiles 140 of the graphical user interface 130 can functionally integrate with the telematics and vehicle information system 100 programs. For example, specific areas or tiles of the graphical user interface can be used to display data from various sources and applications, either in real time or stored. This can be pre-programmed or user-customized, for example. In some embodiments, video input, such as analog video, can also be displayed in the defined tiles.

[0116] Reference Figure 13 The allocation of tile positions and sizes can be user-configurable. In some embodiments, the graphical user interface 130 can be divided into a grid pattern, which can allow the operator to view, for example, one dynamic tile, two dynamic tiles (vertical or horizontal), four dynamic tiles (2 x the size of a single tile chart), or eight dynamic tiles containing charts and text. It should be understood that other shapes and patterns are possible and can be based on the functionality and capabilities of the touchscreen interface.

[0117] As shown in the figure Figure 13Various customized screen layouts are shown. The entire screen 164 can be a single dynamic tile. The graphical user interface can also include a header 166, which may include menu buttons 142. The header 166 can also include a tagline 168, which may identify characters such as company names, etc., and other information such as dates, times, and communication conditions, as non-limiting examples. The graphical user interface 130 can also be divided into two separate dynamic tiles, plus the header 166. One or two of the two dynamic tiles can be divided to produce four dynamic tiles, plus the header 166. Furthermore, each of the four dynamic tiles can be divided to produce a graphical user interface with eight dynamic tiles and the header 166. It should be understood that the graphical user interface can be customized to include variations of the layout shown in the figures.

[0118] Submenus can be generated on touchscreen 122 by touching menu button 142, or by using keypad 124 to highlight and select menu buttons. These submenus can include a list of additional menu items 170, such as... Figure 14 As shown. Selecting any of the listed menu items 170 will bring up further details of the selected menu item. Figure 15 Further details are shown after selecting the "Timer" button 172. These further details may include data, or may include input fields where the operator can enter data into the graphical user interface. Selecting the "Close" button 174 will exit the current screen and return the operator to the screen where they selected the menu button 142. As a non-limiting example, the appearance of the ">" symbol 178 on the right edge of menu item 170 informs the operator that an additional navigation layer is available. It should be understood that any other symbol may be used. The "[Value]" 180 (shown as 12345) on the right edge of the navigation buttons informs the operator of the settings input on the next screen. The "[Value]" displays the current setting and, in some embodiments, may be non-editable.

[0119] Navigation modes - touch mode and keypad mode

[0120] Reference Figure 16 The graphical user interface 130 may be fully touchscreen-enabled. For some operations where the operator is wearing one or more gloves (e.g., when the vehicle is operating in a refrigerator or freezer environment), the touchscreen 122 may be inconvenient to interact with and is not preferred by the operator. In this case, the graphical user interface 130 may also be based on a full menu utilizing the manual input keypad 124, instead of the touchscreen 122 or using it in conjunction with it.

[0121] In some embodiments, the graphical user interface 130 may be touchscreen-oriented and may automatically switch between touch mode and keypad mode depending on how the graphical user interface is used.

[0122] When the integrated display 55 is operating in keypad mode, the graphical user interface 130 may include a highlighted cursor state 184. The operator can use the keypad 124 to move the highlighted cursor 184 to a button, in this example, the "M" button, and can then press an input button on the keypad to "select" or "input" the highlighted cursor button, depending on the button's function.

[0123] In some embodiments, when the touchscreen 122 is touched, the graphical user interface 130 switches to touch mode, and the highlighted cursor state 184 is removed. Removing the highlighted cursor state 184 while in touch mode helps avoid potential uncertainty about the current operating mode of the integrated display 55. If the operator then continues pressing any arrow on the keypad 124, the highlighted state 184 reappears, automatically switching the integrated display 55 back to keypad mode. Touch mode can then be restored when an input button 126 on the keypad 124 is selected, or when the touchscreen 122 is touched again. While in touch mode, only a single keypad input can be used to provide a one-time memory state for switching to keypad mode.

[0124] The integrated display 55 can also support a mixed input mode. In mixed input mode, the integrated display 55 automatically senses input from the touchscreen 122 and the keypad 124, and can accept input from currently available graphical user interface functions. As an example, in mixed mode, when the operator uses the touchscreen keyboard 186 (… Figure 16 When inputting a string of data, keyboard input can be performed after pressing the input button 126 on the keypad 124, rather than pressing the input button 188 on the touchscreen 122. As mentioned above, in touch mode, the highlighted cursor state can be removed. Since there is no highlighted cursor state in the example described, using the input button 126 on the keypad 124 will indicate that the input string of data is complete, compared to inputting the preceding character touched on the touchscreen 122.

[0125] In keypad mode, pressing the input button 126 after moving the arrow button on keypad 124 can be interpreted as a "selection" function. Touching the input button 126 on the touchscreen display 122, i.e., saving the text string, is equivalent to selecting. Therefore, when the operator uses the touchscreen 122 to make a selection and then presses the input button 126 on keypad 124, the input button 126 functions as a "save or input" button.

[0126] Figure 17 As shown Figure 9 The rear exploded view of the integrated display 55 shown includes a touch screen 122, a circuit board 192, a gasket 194, and a cover 198, wherein the cover can also be used as a heat sink.

[0127] Figure 18-19 Other views available on screen 122 according to an embodiment of the present invention are shown. Figure 18 The user configuration for dynamic tiles is shown, as well as the arrangement of multiple dynamic tiles. Figure 19 It shows the touch Figure 15 The screen that displays additional menu items is shown after the down arrow 182.

[0128] Illustrative embodiments of the invention have been described in detail above. Various modifications and additions can be made without departing from the spirit and scope of the invention. Furthermore, since many modifications and variations can be made by those skilled in the art, it is not intended to limit the invention to the exact structures and operations shown and described. For example, according to alternative embodiments, any different features described herein may be combined with some or all of the other features described herein, and details may be changed without departing from the invention as defined by the claims.

[0129] Finally, it will be clearly seen that any processes and steps described herein can be combined, deleted, or reordered. In other embodiments, instructions may be stored in a computer-readable medium, wherein the instructions are executed by a processor to implement one or more processes or steps described herein. Similarly, it will be clearly seen that any process or step described herein can be implemented as hardware, software, including program instructions that execute on a computer, or a combination of hardware and software. Therefore, this specification is also intended merely as an example and not to limit the scope of the invention in any way.
