Without exiting from the component or system test, the technician can simply select the “Repair Info” button 63 to view a menu of additional vehicle technical information available to be accessed directly from the current screen.
- the menu can be a single-level menu—that is, the menu options do not lead to additional menus or other options, but rather directly access a related technical information screen.
- the menu options can be minimized, or limited to technical information specifically related to the current component or system test, in order to simplify the menu structure and avoid potential user confusion.
- the information available to be accessed by way of the “Repair Info” button 63 menu during a vehicle component functional test can be limited to only related information that corresponds to the vehicle type and component currently being tested.
- the information available to be accessed by way of the “Repair Info” button 63 menu during a vehicle type-independent system diagnostic test can be limited to only general, or generic, related information that corresponds to the system currently being tested.
- the technician can then select the desired information, such as a circuit description, a circuit diagram, a connector diagram, or technical specifications from the menu to view the information. For example, while viewing a full-screen data display, the technician can select to view a related circuit diagram, which then replaces the data screen. Similarly, while viewing a dual-display screen that includes a data portion and an information portion, the technician can select to replace the information portion with a related circuit diagram while also continuing to view the data portion of the dual-display. Thus, with a single menu selection, the vehicle technician can access a variety of related vehicle technical information in a single step from the data display.
- the related technical information display can include one or more logical display buttons 62 , including a “BACK” or “EXIT” button 124 , for example, so that the vehicle technician can return directly to the previous display screen with one click of a button.
- the vehicle technician in order to avoid potential user confusion the vehicle technician is not given other options, or menus, from the related technical information display.
- the vehicle technician can switch directly between the data display and the related information display, or between the information portion of the dual-display and the related information display, preventing user confusion that could otherwise result if the technician were given a hierarchy of menu options from the data display.

Thisdisplay panel 66 also can includeadditional data representations 82, for example, aminimum data value 84, anaverage data value 86 and amaximum data value 88 attained during a specified time frame. As yet another example, thedisplay panel 66 can include agraphing meter representation 90 of a data parameter. Here again, thedisplay panel 66 can additionally include a digital numeric representation of thecurrent data value 92 andadditional data representations 94, for example, a minimum data value 96, an average data value 98 and amaximum data value 100 attained during a specified time period. - Furthermore, the digital
multimeter display layout 64 can include one or morelogical display buttons 62 configured to receive user input. One embodiment includes fourlogical display buttons 62 as shown inFIG. 5 . The digitalmultimeter display layout 64 is configured to have the general appearance of a digital multimeter and can display a variety of vehicle diagnostic data, for example, voltage measurements, current measurements, resistance measurements, frequency, alternating current voltage levels (root mean squared), duty cycle, or the like. - The
display screen formatter 46 inFIG. 3 can format the graphical coordinate data or other information data for display in a graphical user interface format on thedisplay device 26. For example, thedisplay screen formatter 46 can format both graphical coordinate data and other vehicle technical information data in a dual-display mode 102, as shown inFIG. 6 , for simultaneous display on separate portions of thedisplay screen 26. As an example, as shown inFIG. 6 , thedisplay screen formatter 46 can format the graphical coordinate data to occupy theupper half 104 of thedisplay screen 26. - In
FIG. 6 , ascope display layout 48 has been formatted to occupy theupper half 104 of thedisplay screen 26, and a vehiclefunctional test procedure 106 has been formatted to occupy thelower half 108 of thedisplay screen 26. Thedisplay screen formatter 46 can reconfigure thescope display layout 48 to have a reduced vertical dimension so that thescope display format 48 can be fitted into theupper half 104 of thedisplay screen 26. In some embodiments the coordinategrid 52 can maintain the same dimensions, but fewer divisions may be shown. In other embodiments, thedisplay screen formatter 46 can reduce the vertical dimension of the coordinategrid 52 to include the same number of divisions in half the vertical space. - Similarly, as shown in
FIG. 7 , thedisplay screen formatter 46 can format a digitalmultimeter display layout 64 to occupy theupper half 104 of thedisplay screen 26, and other vehicle technical information, such as afunctional test procedure 106, to occupy thelower half 108 of thedisplay screen 26. Thus, in dual-display mode 102, a vehicle technician can view vehicle diagnostic data in thescope display layout 48 or in thedigital multimeter layout 64, and other vehicle information such as afunctional test procedure 106 at the same time. Thus, it is not necessary for the vehicle technician to exit the vehicle diagnostic data display mode or consult an external source in order to refer to other vehicle information. - Furthermore, the
display screen formatter 46 can format ascope display layout 48 and a digitalmultimeter display layout 64 for simultaneous display on theupper half 104 and on thelower half 108 of thedisplay screen 26. In this case, thescope display layout 48 and the digitalmultimeter display layout 64 may display the same vehicle diagnostic data in the two different layout formats, or thescope display layout 48 can display different vehicle diagnostic data than the digitalmultimeter display layout 64. In effect, thedisplay screen formatter 46 can format any combination of two display screen layouts to be simultaneously displayed. - In some embodiments, a reference wave form that is typical for a particular vehicle system or component can display on one half of the
display screen 26 while real-time or stored data is displayed on the other half. Thus, while viewing real-time vehicle diagnostic data or stored data regarding a vehicle system or component, the vehicle technician can also view a reference wave form in dual-display mode 102 in order to compare the actual data with the reference data. - In some embodiments, the
display screen formatter 46 can be configured to send the formatted graphical coordinate data representing vehicle diagnostic data to thestorage device 40 to be saved. Similarly, thedisplay screen formatter 46 can be configured to retrieve stored formatted graphical data from thestorage device 40 for display at a later time. - Moreover, in some embodiments, the
display screen formatter 46 can be preprogrammed with a variety of different predetermined display formats, and thedisplay screen formatter 46 can automatically select a display format in which to display the vehicle diagnostic data, based on the type of conditioned vehicle diagnostic data that is received from thesignal conditioning module 16. For example, thedisplay screen formatter 46 can select between ascope display layout 48 and a digitalmultimeter display layout 64, depending on the type of received vehicle diagnostic data. In addition, thedisplay screen formatter 46 can determine the scale or dimension of the divisions of the coordinategrid 52 based on received data parameters, for example, the frequency and the magnitude of the received vehicle diagnostic data. - The
logical display buttons 62 can be associated with a menu of options. For example, alogical display button 62 can be associated with a pop-up menu of screen settings that allow the user to customize the display format, for example, the scale or dimension of the divisions of the coordinategrid 52, the display mode, or the like. As another example, alogical display button 62 can be associated with a pop-up menu that lists a selection of different types of vehicle technical information that is available to be displayed. In addition, alogical display button 62 can be associated with an operation, such as “freezing” the display in order to provide a fixed display, resetting the display to a default format, alternating between the dual-display mode 102 and a full screen mode (seeFIG. 4 ), or the like. - The
information manager 34, depicted inFIG. 8 , can include avehicle selection feature 110, acomponent selection feature 112 and asystem selection feature 114. Thevehicle selection feature 110 can allow the vehicle technician to select a vehicle type in order to gain access to vehicle technical information specific to that vehicle. For example, as shown in the sequence of representative vehicleselection screen shots 111 inFIG. 9 , the technician can select a manufacturer, year, make, category (e.g., “car,” “truck” or “van”), model, series, engine and system, or any other identifiable factor that can distinguish a vehicle type, to specify the subject test vehicle type. - Once the vehicle type has been selected, or specified, as illustrated in
FIG. 9 , theinformation manager 34 can store the vehicle type, for example, in thememory 30, until a new vehicle selection is made or until the vehiclediagnostic tool 10 is powered down. Furthermore, in some embodiments, the vehicle type selection can be stored in non-volatile memory, for example, in a flash memory device, so the vehicle type selection will remain valid after the vehiclediagnostic tool 10 is powered down and newly powered up. Thus, theinformation manager 34 can retrieve or provide only information applicable to the selected vehicle type, for example, throughout a diagnostic session—which can include a series of component functional tests and system diagnostic tests, as well as other diagnostic tests on the subject test vehicle—or during multiple diagnostic sessions. The technician is not required to reenter the vehicle type for each individual diagnostic test, but rather can continue from one test to another receiving information specific to the subject test vehicle during a series of tests on various vehicle components or systems. - In addition, as illustrated in the sequence of component
selection screen shots 113 inFIG. 10 , thecomponent selection feature 112 can allow the vehicle technician to select a particular component of a vehicle to be tested, such as an intake temperature sensor, an oxygen sensor, a cooling water temperature sensor, or the like. The component selection can then be stored throughout a component functional test session, in order to provide access to component-specific vehicle technical information, which may be specific to a particular vehicle or may be vehicle-independent. Theinformation manager 34 can then display an appropriate set of vehicle-specific test instructions. For example, as shown inFIG. 10 , the technician can select a specific component test, such as an intake air temperature test, and theinformation manager 34 can provide an associated information display, such asfunction test instructions 106, along with an appropriate data display, such as a digitalmultimeter display layout 64. - As illustrated in the sequence of system
selection screen shots 115 inFIG. 11 , thesystem selection feature 114 can further allow the vehicle technician to select a particular vehicle system for testing, such as an engine, a transmission, an anti-lock brake system, a power train system, or the like. The system selection can then be stored throughout a system diagnostic test session, in order to provide access to system-specific vehicle technical information, which may be specific to a particular vehicle or may be vehicle-independent. In some embodiments, the vehicle system can be independent of the vehicle type; for example, vehicle system tests can include general instructions for testing systems that can be found on many vehicle types, but which are generally similar enough to permit a generic functional test. Theinformation manager 34 can provide an associated information display, such asfunction test instructions 106, along with an appropriate data display, such as ascope display layout 48. - The
information manager 34 can be configured to access the vehicletechnical information database 32, and retrieve a selected segment of the vehicle technical information. Theinformation manager 34 can then send the vehicle technical information to theuser interface builder 38 for display. Thus, theinformation manager 34 can provide the specific vehicle, system or component technical information requested by the vehicle technician. - For example, the
user interface builder 38 can receive a functional test procedure 106 (seeFIGS. 6 and 7 ) from theinformation manager 34 and format thefunctional test procedure 106 for display on thedisplay device 26. InFIG. 6 thedisplay screen 26 is displaying an oxygen BAR test procedure (promulgated by the California State Bureau of Automotive Repair) in thelower half 108 of thedisplay screen 26. A second example of a representativefunctional test procedure 106 is shown inFIG. 7 , where thedisplay screen 26 includes an input air temperature (IAT) test procedure in thelower half 108 of thedisplay screen 26. In one embodiment, thedisplay screen formatter 46 provides a dual display screen by default, including ascope display layout 48 and afunctional test procedure 106 for the current vehicle component that has been selected. - Moreover, the vehicle technician can select vehicle technical information from a menu at a data display screen or a dual-display screen. For example, using a
logical display button 62, such as the “Repair Info”button 63 shown inFIG. 7 , the vehicle technician can choose to display additional vehicle technical information related to the component test or system test currently being performed. Without exiting from the component or system test, the technician can simply select the “Repair Info”button 63 to view a menu of additional vehicle technical information available to be accessed directly from the current screen. The menu can be a single-level menu—that is, the menu options do not lead to additional menus or other options, but rather directly access a related technical information screen. - Furthermore, the menu options can be minimized, or limited to technical information specifically related to the current component or system test, in order to simplify the menu structure and avoid potential user confusion. For example, the information available to be accessed by way of the “Repair Info”
button 63 menu during a vehicle component functional test can be limited to only related information that corresponds to the vehicle type and component currently being tested. Similarly, the information available to be accessed by way of the “Repair Info”button 63 menu during a vehicle type-independent system diagnostic test can be limited to only general, or generic, related information that corresponds to the system currently being tested. - The technician can then select the desired information, such as a circuit description, a circuit diagram, a connector diagram, or technical specifications from the menu to view the information. For example, while viewing a full-screen data display, the technician can select to view a related circuit diagram, which then replaces the data screen. Similarly, while viewing a dual-display screen that includes a data portion and an information portion, the technician can select to replace the information portion with a related circuit diagram while also continuing to view the data portion of the dual-display. Thus, with a single menu selection, the vehicle technician can access a variety of related vehicle technical information in a single step from the data display.
- Furthermore, as shown in
FIG. 13 , the related technical information display can include one or morelogical display buttons 62, including a “BACK” or “EXIT”button 124, for example, so that the vehicle technician can return directly to the previous display screen with one click of a button. In fact, in some embodiments, in order to avoid potential user confusion the vehicle technician is not given other options, or menus, from the related technical information display. Thus, the vehicle technician can switch directly between the data display and the related information display, or between the information portion of the dual-display and the related information display, preventing user confusion that could otherwise result if the technician were given a hierarchy of menu options from the data display. - In some embodiments, another
logical display button 62 on the related technical information display, for example, a “PRINT”button 126 to permit the vehicle technician to print the vehicle technical information being displayed with a single click of the “PRINT”button 126. In addition, any of the vehicle technical information screens can include navigation tools such as thescroll bar 128 shown inFIG. 13 . - In some embodiments, the related technical information can include a circuit description, such as the
representative circuit description 116 for a heated oxygen sensor shown inFIG. 12 . When the circuit description is requested by a user, theinformation manager 34 can access a circuit description file in the database and send the circuit description information to theuser interface builder 38. Thedisplay screen formatter 46 can then format thecircuit description 116 for display on thedisplay screen 26. For example, thecircuit description 116 can include a basic circuit schematic 118 as well as atext description 120 of the circuit and its functionality. Thus, the vehicle technician can quickly and conveniently access a detailed description of the currently selected component. Thedatabase 32 can include circuit description information for any number of different vehicle electrical circuits. - Furthermore, in some embodiments, the
information manager 34 can access vehicle wiring information in the database and dynamically create from the wiring information a wiring circuit diagram 122, such as the representative circuit diagram shown inFIG. 13 , representing a wiring circuit for a component or system of the vehicle, for example, including wire colors and names. That is, the wiring information stored in the database does not include an image file, but rather includes relationship information regarding the wiring between vehicle components, which theinformation manager 34 can use to dynamically create at the time a circuit diagram 122 is requested an image file representing the electrical wiring circuit. The created image file is then sent to theuser interface builder 38 and thedisplay screen formatter 46 formats the circuit diagram image for display on thedisplay screen 26. Nevertheless, in an alternative embodiment the wiring information stored in the database can include an image file, such as a bitmap file, JPEG file, TIFF file, GIF file, or other standard or proprietary image format file. - Additionally, the
information manager 34 can access a connector diagram file in the database, for example, showing the connector pin-out and correct connection, and send the connector diagram information to theuser interface builder 38. Thedisplay screen formatter 46 can then format a connector diagram 130 for display on thedisplay screen 26, such as the representative connector diagram 130 as shown inFIG. 14 . Furthermore, theinformation manager 34 can access component specification information in the database, for example, including proper sensor operating values for specific operating conditions, and send the component specification information to theuser interface builder 38. Thedisplay screen formatter 46 can then format thecomponent specification 132, such as therepresentative component specification 132 shown inFIG. 15 , for display on thedisplay screen 26. - Moreover, the
information manager 34 can access a collection of known possible vehicle conditions and associated repair guidelines in the database and send the information to theuser interface builder 38. Thedisplay screen formatter 46 can then format a known possible vehicle condition and associated repair guideline information, such as therepresentative condition 134 andrepair guideline 136 shown inFIG. 16 , for display on thedisplay screen 26. - In some embodiments, the technical information management device can further include a data-only mode, or training mode, in which the
information manager 34 can retrieve vehicle technical information and simulated vehicle diagnostic data from thedatabase 32 and send the information and data to theuser interface builder 38, which can prepare the information and data for display. The training mode display also can include instruction text on the display to help the vehicle technician understand how to use the technical information management device. - In an alternative embodiment, the
database 32 can be designed to receive software updates independent from theinformation manager 34 and theuser interface builder 38. Thus, thedatabase 32 can be updated without updating theuser information builder 38 or theinformation manager 34. Likewise, theinformation manager 34 anduser interface builder 38 can be updated without updating thedatabase 32. This architecture gives vehicle technicians added flexibility to efficiently update the desired portions of the technical information management device. Additionally, in one embodiment, the technical information management device can be updated using the proprietary next generation information system (NGIS) software, manufactured by the OTC Division of the SPX Corporation in Owatonna, Minn. - Furthermore, the
database 32 can be encrypted. That is, the data recorded in thedatabase 32 can be encoded using a cryptographic algorithm that reconfigures the data in such a manner that it is difficult for the data to be interpreted without an encryption key. In this case, theinformation manager 34 can be configured to decrypt, or decode, the vehicle technical information after it has been accessed and retrieved from the database. The encryption method can include any of numerous suitable encryption algorithms known in the art. - The many features and advantages of the invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention which fall within the true spirit and scope of the invention. Further, since numerous modifications and variations will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
