Description:
FIELD 
       [0001]    The present disclosure relates to assembly line testing of a completed vehicle, and more particularly to a system and method for testing a completed vehicle, wherein the testing system is integrated into the controllers of the vehicle. 
         [0002]    BACKGROUND AND SUMMARY 
         [0003]    When any product, including a work machine, is produced, it is a generally accepted good practice to test one or more of each run for quality assurance purposes. Such testing can take the form of actually using the device, a visual inspection, or otherwise. For some electronic devices, or devices containing software, a visual inspection will not suffice to fully test the device. For some work machines, a distinct testing stand may be produced for the purposes of attaching it to a completed work machine to perform diagnostic procedures for detecting proper operation of various vehicle systems. This test stand is a stand-alone device that is hooked up to completed work machines to be able to access and test the electronic workings and software workings of the work machine. Thus, the test stand is a fully separate system that needs its own designing, building, and maintenance. Additionally, as the work machines being tested are changed and/or improved, similar changes and updates may be necessary for the test stand. Accordingly, what is needed is the ability to test work machines without the above noted drawbacks. 
         [0004]    According to an embodiment of the present disclosure, a vehicle is provided including: a chassis; a ground engaging mechanism configured to support the chassis; an electric motor configured to drive the ground engaging mechanism; a power source configured to provide power to the electric motor; a controller configured to control the electric motor and other vehicle systems, the controller including a processor, an electronic storage device fixedly integrated into the vehicle and having software thereon. When invoked via the controller, the software causes the controller to execute the steps of: instructing a user to perform steps to activate a first vehicle feature; recording electronic communications indicative of whether the steps to activate the first vehicle feature were taken; instructing the user to indicate whether the first vehicle feature was activated as expected in response to the steps taken to activate the first vehicle feature; determining whether the recorded communications and user input indicate a passing or failing of the first vehicle feature; and storing the determination on the electronic storage device. 
         [0005]    According to another embodiment of the present disclosure, a method of testing work machine assembly is provided including the steps of: fixedly coupling a work machine control interface into the work machine such that the control interface is fixedly mounted within a cab of the work machine and readily accessible to an operator of the work machine seated in a seat located in the cab; providing a control system electrically coupled to the work machine control interface, the control system being coupled to an electronic storage device; and using the control interface to access programming stored on the electronic storage device. The programming causing the control system to perform the steps of: instructing a user to perform steps to activate a first vehicle feature; recording electronic communications indicative of whether the steps to activate the first vehicle feature were taken; instructing the user to indicate whether the first vehicle feature was activated as expected in response to the steps taken to activate the first vehicle feature; determining whether the recorded communications and user input indicate a passing or failing of the first vehicle feature; and storing the determination on the electronic storage device. 
         [0006]    According to yet another embodiment of the present disclosure, a method of assembling a work machine is provided including the steps of: receiving a work machine frame; attaching a control system interface and a control system electrically to an electronic storage device and physically to the frame, the control system interface including a screen viewable by a user; attaching a first accessory physically to the work machine frame and electronically to the control system and control system interface; using the control system interface to invoke programming stored on the electronic storage device. The programming causing the control system to test the first accessory by: instructing a user to interact with the control system interface to call for operation of the first accessory, determining if desired signals were sent to the first accessory; and requesting that the user indicate whether the first accessory performed as desired. The method further including the steps of attaching a second accessory physically to the work machine frame and electronically to the control system and control system interface after the first accessory is tested; and using the control system interface to invoke programming stored on the electronic storage device to cause the control system to test the second accessory by: instructing a user to interact with the control system interface to call for operation of the second accessory, determining if desired signals were sent to the second accessory; and requesting that the user indicate whether the second accessory performed as desired.

       DETAILED DESCRIPTION 
       [0013]    The embodiments disclosed herein are not intended to be exhaustive or to limit the disclosure to the precise forms disclosed in the following detailed description. Rather, the embodiments are chosen and described so that others skilled in art may utilize their teachings. 
         [0014]    Referring to  FIG. 1 , an exemplary work vehicle in the form of excavator  10  is provided. Although the utility vehicle is illustrated and described herein as excavator  10 , the utility vehicle may include a loader, motor grader, tractor, a bulldozer, a feller buncher, a crawler, a skidder, a forwarder, or another utility vehicle. Excavator  10  includes a chassis  12  and a ground drive element or ground engaging mechanism  14 . Ground engaging mechanism  14  is capable of supporting chassis  12  and propelling chassis  12  across the ground  15 . Although the illustrated excavator  10  includes tracks as ground engaging mechanism  14 , excavator  10  may include other ground engaging mechanisms, such as wheels or other suitable ground engaging members. 
         [0015]    Excavator  10  further includes Vehicle Control Unit (VCU)  100  and Engine Control Unit (ECU)  120  controllable via Primary Display Unit (PDU)  16 . VCU  100  controls many features of excavator  10  such as Automatic Temperature Controlled (ATC) HVAC unit  20 , AM/FM/Weather band radio  22 , hydraulic systems  28 , lights  30 , washer/wipers  32 , joystick controllers  34 , and many additional electrical components. ECU  120  determines the amount of fuel, ignition timing and other parameters an internal combustion engine needs to keep running ECU  120  reads values from multidimensional performance maps and uses input values (e.g. engine speed) calculated from signals coming from sensor devices monitoring the engine. 
         [0016]    As illustrated in  FIG. 2 , PDU  16  provides a user interface for the electronics and software employed on excavator  10 . PDU  16 , is electronically coupled to VCU  100  and ECU  120 . 
         [0017]    PDU  16  includes a service mode  24 . Within service mode  24  is test stand module  26 . PDU  16  operates via a Controller-area network (CAN or CAN-bus). CAN is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. The CAN is accessible via a JDLink Service ADVISOR connector  46  to which PDU  16  is linked. 
         [0018]    Test stand module  26  provides programming to test the functionality of various excavator  10  functions. The assembly of excavator  10  provides that many different systems of excavator  10  may be assembled at many geographically dispersed locations. At the conclusion of the assembly of a portion of excavator  10 , that portion is tested. As previously noted, the use of external, stand-alone testing stands requires that multiple test stands be provided at each of the various geographically dispersed assembly locations. Furthermore, multiple test stands are necessary within an assembly plant to correspond to each system assembly testing point. PDU  16  of the present disclosure provides the testing software traditionally present on test stand integrally with the PDU  16  and thus excavator  10 . Accordingly, excavator  10  of the present disclosure does not require the manufacturing locations to provide test stands. 
         [0019]    In one embodiment, the test stand module within PDU  16  consists of a single program that executes all tests of excavator  10  at a single time. In another embodiment, the test stand module within PDU  16  is broken into multiple test protocols such that less than all available tests are run at any one time. Such an embodiment is implemented in the case where the assembly of excavator  10  occurs at multiple geographically dispersed locations. However, such an embodiment is also implemented for assembly that occurs in a single geographic location where distinct testing is desired at multiple sub-assembly completion sites. 
         [0020]    As previously discussed, (ATC) HVAC unit  20 , AM/FM/Weather band radio  22 , hydraulic systems  28 , lights  30 , washer/wipers  32 , joystick controllers  34 , and many additional electrical components are each tested either alone, grouped together in modules, or all grouped together. Embodiments of such tests are shown in  FIGS. 5   a - n  and described below. Each of  FIGS. 5   a - n  show PDU  16  displayed text, PDU  16  displayed user response options, and VCU software actions performed in response to the user response. 
         [0021]    Lights  30  are tested to ensure that all installed lights are operating correctly. The test also ensures that the proper lights are enabled for the particular excavator  10  under test. As shown in  FIG. 5   a , the test of lights  30  starts with displaying the question “All work lights off?”  510  to a user via PDU  16 . The user is further shown indications that responding by pressing “1” on PDU  16  indicates an affirmative answer to the question and pressing 2 on PDU  16  indicates a negative answer to the question. VCU  100  retains the user&#39;s input and then proceeds to the next step  520 . Step  520  instructs the user to “Press the SSM Work Light Button.” VCU  100  then records and verifies the CAN messaging indicating that the instructed step was taken. VCU  100  then 
         [0022]    Excavator  10  is first configured to ready it for testing. According to serialization protocols, a VIN for excavator  10  is obtained. The machine VIN is entered via operator input and the chosen options for the specific excavator being built are input through an ECU_Controller program on a bench setup. This is completed prior to the VCU being installed in the excavator. This shall be completed prior to the VCU being installed in the excavator. 
         [0023]    Subsequently, engine controllers are programmed in the factory to match the specific engine. This is also completed through the ECU_Controller program on a bench setup prior to the VCU being installed in the excavator. 
         [0024]    The VCU normally arrives with the correct software pre-installed. However, there are occasions when software updates are made for many potential reasons. Due to the time involved in shipping VCU&#39;s from the supplier to the factory, there will likely be times when the VCU needs to be re-programmed to get the correct software. 
         [0025]    Once setup and correctly programmed, the VCU and ECU are installed on the excavator  10 . This installation includes coupling VCU and ECU to PDU  16 . Once all of the controllers are installed, a clear codes activity is completed to remove all diagnostic trouble codes from the bench top programming. 
         [0026]    For any testing, whether being performed as single instance covering all tests, or any module consisting of less than all available tests, the protocol of  FIG. 4  is followed. Once test stand module is invoked within PDU  16 , exiting this module will only be allowed once all tests have successfully passed or by invoking a back-door exit. Step  400  provides for the invoking of the particular testing module. Step  410  invokes a particular test within the chosen test module (test “x”). When immediately following step  400 , step  410  invokes the first test of the module (x=1). Embodiments of the modules are provided below. If necessary, step  420  cycles the power of excavator  10 . The pass/fail status of the test is stored at step  430 . Step  440  determines if all tests within the module have been run (n=number of tests within the module). If all tests within the module have not been run, steps  410 - 440  are cycled until all tests in the module have been run. 
         [0027]    If all tests have been run analysis of the tests begins at step  450  that asks if all tests were passed. If so, the program ends at step  460 . If not, the failed tests are displayed at step  470  and the user is given the option to re-run the failed test, step  480 . If a test repeatedly fails, the user utilizes the backdoor exit to end the program. 
         [0028]    Test embodiments are listed below.

         [0051]    Upon completion of each of the above tests, VCU  100  retains the results in a memory location that allows for memory access via CAN (Step  430 ). In one embodiment, the results are formatted as:
       0x00→test not run, not applicable (vehicle options)   0x01→test passed first time   0x10→test failed   0x11→original test failed, but issue has since been resolved       
 
         [0056]    If all tests are passed, then excavator  10  is ready to receive its electronic “birth certificate.” The birth certificate is a summary of the results of all testing that was completed. It keeps track if each individual test passed the first time or did not pass the first time and required rework. The birth certificate records the pilot pressures developed during each of the hydraulic tests, which can be used in the future to check the component life of this machine or be used to track quality levels of all parts coming in from a supplier. The birth certificate records of all DTC (Diagnostic Trouble Codes) that were present during the EOL tests. The birth certificate provides a record that the machine left the factory in working order, so that if an issue exists when the machine reaches a dealership the manufacturer knows that it occurred in shipping and work to eliminate those issues. The birth certificate records that the HVAC system is operating properly so that the manufacturer can understand potential leaks if the HVAC is no longer working after delivery to a customer. Excavator  10  is hooked up to an external computer that verifies that all tests are passed. The external computer then transfers the birth certificate to excavator  10  that verifies that all tests have been passed. 
         [0057]    Furthermore, once a dealer receives the vehicle, the dealer can again replicate the above described tests to ensure that the vehicle is in proper working order. Any problems discovered can be compared to the test values present in the birth certificate to determine if the discovered problem is likely to have occurred during shipping. 
         [0058]    While this invention has been described as having preferred designs, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this disclosure pertains and which fall within the limits of the appended claims.
