Not Applicable.
The present application is related to methods and procedures for conducting a rapid safety check of several different parameters of a motor vehicle, and in particular, to methods and procedures for carrying out a series of vehicle safety checks including, but not limited to, vehicle and customer identification, wheel alignment measurement, battery testing, brake testing, tire tread depth measurement, tire pressure monitoring, and documentation and review of vehicle diagnostic trouble codes and test results using a multi-function vehicle service system and single vehicle service bay or inspection lane.
Vehicle owners generally do not bring vehicles to a service or repair shop unless the vehicle is due for a scheduled maintenance procedure or the owner has detected something is wrong with the vehicle. It is not uncommon for vehicles which are not routinely serviced will have worn or damaged components unknown to the owner/operator which may potentially have a negative impact on the safe operation of the vehicle.
Automotive service shops will routinely perform safety checks on vehicles brought in for service. However, these safety checks are time consuming and often require multiple different vehicle service systems, such as a vehicle wheel alignment measurement system, a vehicle brake testing system, and/or a vehicle diagnostic code analyzer. These different and independent service systems may be located at different locations throughout a vehicle repair shop, requiring the vehicle to be moved from one location to the next, in order to perform a diagnostic procedure at each station. The results of these discrete safety checks and/or measurements are then compiled from the individual service systems, and subsequently communicated to the vehicle owner. Often, due to the time required to complete the various individual vehicle safety checks using the different vehicle service systems and service bays, the owner will no longer be present at the shop premises. The result is that the owner may not be informed of the additional needed repairs or services until a much later time, often after completion of the repair or service for which the vehicle was initial brought to the shop. At this point, the vehicle owner will often decline to proceed with any additional repairs, and the vehicle service or repair shop fails to profit from having conducted the additional vehicle safety checks and/or inspections.
Accordingly, it would be advantage to provide a vehicle service or repair shop with an efficient means for identifying a vehicle and customer, and for automating or carrying out a series of vehicle safety checks including, but not limited to, vehicle battery testing, wheel alignment measurements, brake testing, tire tread depth measurement, tire pressure monitoring, and a review of vehicle diagnostic trouble codes using a single multi-function vehicle service system and a single vehicle service bay or inspection lane. It would be further advantageous for the comprehensive results of the several vehicle safety checks to be quickly provided to a vehicle owner/operator in a summary report in order to obtain approval to conduct necessary repairs and/or vehicle services.
Briefly stated, the present disclosure provides a method and apparatus for conducting a plurality of vehicle service measurement and/or safety check procedures using a single multi-function vehicle service system and a single vehicle service bay or inspection lane, whereby results of one or more vehicle safety checks can be quickly provided to a vehicle owner/operator through a comprehensive customer report in order to obtain approval to conduct necessary repairs and/or vehicle services.
A further embodiment of the present invention provides a method and apparatus for conducting a plurality of vehicle service measurement and/or safety check procedures using a single multi-function vehicle service system and a single vehicle service bay or inspection lane, whereby results of several different vehicle safety checks can be quickly provided to a service technician through a detailed technician report including diagnostic information to facilitate the completion of repairs and/or vehicle services.

In an embodiment of the present disclosure, a multi-function vehicle service system associated with a vehicle service bay or inspection lane is configured to acquire and store data associated with individual customers and their vehicles at various stages of a vehicle service or inspection procedure. The data may be acquired by either manual input, communication from remote computer system such as a shop management system, or by scanning of machine-readable information, such as bar codes associated with a vehicle identification number and/or customer driver license. Additional data may be acquired by digitally imaging the vehicle or portions of the vehicle, such as a license plate or worn vehicle component, and the resulting images processed to extract identifying data. The identifying data may be utilized to access or create a customer or vehicle record, either at the vehicle service system or at a remote computer system such as the shop management system, in which the results of current service or inspection procedures may be stored, together with a history of previous vehicle service records. The records may be stored locally or communicated to a remote data repository where they may be accessed as needed during a vehicle service procedure or to facilitate the generate of various reports or the identification of trends.
The foregoing features, and advantages set forth in the present disclosure as well as presently preferred embodiments will become more apparent from the reading of the following description in connection with the accompanying drawings.
In the accompanying drawings which form part of the specification:
Corresponding reference numerals indicate corresponding parts throughout the several figures of the drawings. It is to be understood that the drawings are for illustrating the concepts set forth in the present disclosure and are not to scale.
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings.
The following detailed description illustrates the invention by way of example and not by way of limitation. The description enables one skilled in the art to make and use the present disclosure, and describes several embodiments, adaptations, variations, alternatives, and uses of the present disclosure, including what is presently believed to be the best mode of carrying out the present disclosure.
In general, vehicle maintenance procedures carried out by an automotive service shop or dealer 10 begin with the vehicle undergoing the maintenance being brought into the maintenance area, service bay, or service location 12, such as shown in
The methods of the present disclosure are carried out by a service technician under the guidance of the multi-function vehicle service system or vehicle inspection system 100 associated with the service bay 12. The multi-function vehicle service system or vehicle inspection system 100 generally includes a console 102 and is configured with a suitably programmed processing system and user interfaces such as a keyboard, a bar code scanner, a display, a printer, a GUI, etc., The system further includes at least one communication interface 106 such as a wireless connection or internet connection, to communicate instructions and/or data to various diagnostic sensors, to receive and/or access measurement results obtained by diagnostic sensors, and to access procedural guidance instructions, customer and vehicle records, shop supply inventory, and vehicle specification databases. By providing bi-directional communication between the multi-function vehicle service system or inspection system 100 and various diagnostic sensors or measurement devices, data necessary to conduct a diagnostic or measurement procedure may be automatically communicated as necessary to the diagnostic sensor or measurement devices as needed. In addition, instructions or guidance can be provided directly at the diagnostic sensor or measurement device to an operator during a diagnostic or measurement procedure, directing the operator to a next step in the procedure without requiring the operator to maintain a line-of-sight to a display or console associated with the multi-function vehicle service system or vehicle inspection system.
The processing system of the multi-function vehicle service system 100 is further configured with suitable software instructions for generating reports and visual displays on an associated display device setting forth identifying information, measurements, required repairs, and/or vehicle diagnostics associated with a vehicle undergoing a service procedure. The reports and displays are configured to enable the service technician to present relevant information to a waiting customer. As described herein, a multi-function vehicle service system may be further configured with suitable software instructions to carry out one or more vehicle service or repair procedures, such as, but not limited to, vehicle wheel alignment angle adjustments. In contrast, a vehicle inspection system generally does not include software instruction for carrying out vehicle service or repair procedures, and is generally limited carrying out inspection and diagnostic procedures to acquire data and measurements for the purpose of generating suitable reports and/or data communications. The hardware configuration of a vehicle inspection system may be substantially identical to that of a multi-function vehicle service system 100, but for the programming by different software instructions.
Initially, upon entry into the service bay 12, the vehicle is identified to the multi-function vehicle service system or vehicle inspection system 100, and relevant data associated with the vehicle type, the specific vehicle itself, and/or the vehicle owner is retrieved by the multi-function vehicle service system or vehicle inspection system 100 from either local data storage or over a suitable communications link from one or more remote data repositories or computer systems 108. Vehicle identification and/or customer identification can be provided to the multi-function vehicle service system or vehicle inspection system 100 by a variety of means, including the use of scanning devices, imaging sensors, and/or digital cameras. For example, in one embodiment, the multi-function vehicle service system or vehicle inspection system 100 is configured to utilize an electronic scanner 110 to optically scan a customer's driver license. Driver licenses from most states contain machine-readable data, such as a “2D” bar code on the back surface, which encodes the driver's name and address information, and which can be decoded by the multi-function vehicle service system or vehicle inspection system 100 using suitable software instructions. Similarly, the multi-function vehicle service system or vehicle inspection system 100 may incorporate one or more cameras or imaging sensors 112 configured to acquire images of the vehicle disposed within the service bay 12. The acquired images are processed by the multi-function vehicle service system to extract vehicle identifying information, such as the alpha-numeric characters on a vehicle license plate, which may be then evaluated via optical character recognition technology to identify the specific vehicle and/or customer by cross-reference to previously stored customer data. Once the vehicle and/or customer are identified, the multi-function vehicle service system or vehicle inspection system 100 can access the appropriate customer and vehicle prior service records (if present either locally or on a remote system 108), and can present the identifying information on a display screen 104 or a vehicle condition report as shown in
Preferably, as seen in
Utilizing alignment angle measurements communicated from the sensors or calculated from acquired images, the multi-function vehicle service system or vehicle inspection system 100 is further configured to provide the service technician with measurement information in the form of a visual display or a portion of a comprehensive printed report as shown in
In a further embodiment, a brake test system 114 having a set of brake test plates 20 and associated sensors is optionally disposed on the floor 14 or vehicle support structure 15 (i.e. lift rack), as seen in
In a further embodiment, a tire condition measurements system 116 having one or more associated tire condition sensors 30, which may be configured to measure one or more characteristics of a the vehicle tires, such as the remaining tread depth of individual tires, tire pressure, tread wear patterns, or tire defects, is disposed in the vehicle service bay 12 and operatively coupled to the multi-function vehicle service system or vehicle inspection system 100. The tire condition sensors 30 may be optical sensors embedded in the surface 14 or vehicle support structure 15 over which the vehicle is driven, such as shown in U.S. Pat. No. 7,578,180 to Lionetti or in U.S. Patent Application Publication No. 2010/0292953 A1 to Pingel, both of which are herein incorporated by reference.
Alternatively, a tire condition sensor 30 may consist of an optical or physical hand-held tire tread depth measurement device which is operatively positioned by an operator to acquire one or more tire tread depth measurements at individual vehicle wheels, such as shown in U.S. Pat. No. 5,895,845 to Burger, herein incorporated by reference. The tire condition sensor 30, when in a hand-held configuration, preferably receives data from the multi-function vehicle service system or vehicle inspection system 100 to enable the sensor 30 to provide an operator with guidance as to which vehicle wheel to measure, and how many measurements to take at each vehicle wheel. Such information may be conveyed to the operator, for example, by means of simple illuminated lights, via a graphical display panel on the sensor 30, via an audible sound, or by vibration of the hand-held device. By providing the operator with guidance directly at the sensor 30, the operator is relieved from the need to have a line-of-sight view to a display associated with the system 100 while acquiring tire measurements. The measured tread depths or other tire characteristics recorded by the tire condition sensors 30 are subsequently communicated to the multi-function vehicle service system or vehicle inspection system 100, such as over a wireless communications link, and are analyzed by the multi-function vehicle service system or vehicle inspection system 100 to identify any potential tire wear problems associated with the vehicle. Based on the results of these measurements, the multi-function vehicle service system or vehicle inspection system 100 is configured to provide the service technician with information, in the form of a visual display or a portion of a printed report as shown in
In a further embodiment, a tire pressure measurement system 118 configured to obtain measurements the inflation pressure of individual tires is disposed in the vehicle service bay 12 and operatively coupled to the multi-function vehicle service system or vehicle inspection system 100. The tire pressure measurement system 118 may be configured with one or more pressure gauges for directly measuring tire inflation pressure at the tire valve stems, or may be configured with sensors for communication with tire pressure monitoring sensors installed in the individual wheel assemblies of the vehicle. The tire pressure measurements obtained by the gauges or sensors are communicated to the multi-function vehicle service system or vehicle inspection system 100, such as over a wireless communications link, and are analyzed by the multi-function vehicle service system or vehicle inspection system 100 to identify any over-inflation or under-inflation conditions present in the vehicle wheel assemblies. Based on the results of these measurements, the multi-function vehicle service system or vehicle inspection system 100 is configured to provide the service technician with information, in the form of a visual display or printed reports as shown in
In a further embodiment, a communication means 500 is provided for establishing a communication link between the multi-function vehicle service system or vehicle inspection system 100 and an electronic control module (ECM) of a vehicle disposed in the service bay 12, such as shown in U.S. Patent Application Publication No. 2005/0171662 A1 to Strege et al. and U.S. Pat. No. 7,359,775 B2 to Strege et al. (both of which are herein incorporated by reference). The communication means 500 is configured to enable the multi-function vehicle service system or vehicle inspection system 100 to acquire vehicle parameters directly from the vehicle ECM. The acquired information may include, but is not limited to vehicle identification, TPMS data, tire pressure, tire temperature, battery life remaining, stored error codes, and other stored OBD-II codes. Using the data acquired from the vehicle ECM, the multi-function vehicle service system or vehicle inspection system 100 is configured to provide the service technician with information in the form of a visual display or printed reports as shown in
In a further embodiment, a battery testing system 600, such as battery diagnostic device manufactured by Midtronics, Inc. of Willowbrook, Ill., is provided at the vehicle service bay 12 for testing the condition of the vehicle's battery and communicating battery test results to the multi-function vehicle service system or vehicle inspection system 100. The battery testing device 600 provides a rapid test of the vehicle's battery to determine whether the battery should be replaced; is marginal; or needs to be recharged. The battery testing device is configured for bi-directional communication with the multi-function vehicle service system or vehicle inspection system 100, both to receive instructions therefrom and to transmit test results thereto. In an exemplary battery testing procedure, such as set forth in the flowchart of
Turning to
Once operatively connected, the battery testing system 600 is activated (Box 808) and communication with the multi-function vehicle service system or vehicle inspection system 100 is established (Box 810). With communication established, operating parameters specific to the identified battery of the vehicle undergoing testing are retrieved (Box 812) from the battery information database by the multi-function vehicle service system or vehicle inspection system 100 and communicated to the battery testing system (Box 814). Battery operating parameters may include the battery cold cranking amps (CCA), the location of the battery terminals, the composition of the battery, the battery brand, as well as any other battery-specific information which may be relevant. After receiving the battery-specific information, the battery testing system is coupled to the vehicle battery and a test procedure is run to evaluate the operating condition of the vehicle battery (Box 816).
Once the test procedure is completed, the results are evaluated to determine if the battery testing system had sufficient battery information to properly evaluate the results of the test procedure (Box 818). If sufficient battery information was present, the battery testing system communicates the results of the test procedure to the multi-function vehicle service system or vehicle inspection system (Box 820) for display and/or inclusion in either a customer or technician report (Box 822). The results of the test procedure may include specific data such as the voltage and measured CCA, as well as a simplified determination of the overall condition of the battery such as “Good”, “Marginal” or “Recharge”.
If it is determined that the battery testing system either had incorrect information, or did not have sufficient battery information to properly evaluate the results of the test procedure, the battery testing system may either communicate the results of the test procedure, together with a data error message, to the multi-function vehicle service system or vehicle inspection system (Box 820) for display and/or inclusion in either a customer or technician report (Box 822), or request updated battery-specific information and repeat the test procedures. Optionally, the request for additional or updated battery information is communicated to the multi-function vehicle service system or vehicle inspection system 100 (Box 826), which in turn prompts the service technician to manually update the battery-specific information with any corrections or changes (Box 828). Any corrections or changes to the battery-specific information (such as the CCA capacity of a non-OEM installed battery) are then communicated back to the battery testing system 600 (Box 830), and the battery test procedure is re-run using the updated battery specific information (Box 816). The battery testing system may also receive information from the multi-function vehicle service system or vehicle inspection system 100 to convey to the operator, for example, by means of simple illuminated lights, via a graphical display panel on the battery testing system, 600, via an audible sound, or by vibration. By providing the operator with guidance directly at the battery testing system, 600, the operator is relieved from the need to have a line-of-sight view to a display associated with the system 100 while acquiring battery measurements.
Those of ordinary skill in the art will recognize that a single vehicle service bay 12 and multi-function vehicle service system or vehicle inspection system 100 may be configured with all or some of the features of the present disclosure, and that the ability of the multi-function vehicle service system to carry out additional vehicle service procedures and diagnostic checks not listed herein may incorporated into the system of the present disclosure, depending upon the service capabilities of the vehicle repair shop 10, without departing from the scope of the present disclosure. During a vehicle service procedure, the multi-function vehicle service system or vehicle inspection system 100 may be utilized by a service technician to identify a vehicle, communicate with, and acquire measurements associated with a vehicle from, various diagnostic and measurement devices as the vehicle is brought into the service bay or inspection lane 12 and is subsequently disposed on the vehicle support surface 14 or lift rack 15. By initially identifying the vehicle, and enabling the multi-function vehicle service system or vehicle inspection system 100 to communicate with various diagnostic and measurement devices, vehicle specific information necessary to properly carry out a diagnostic procedure or measurement may be conveyed directly to the diagnostic or measurement device without requiring additional interaction from the service technician. When properly utilized by the service technician, the multi-function vehicle service system or vehicle inspection system 100 provides the service technician with a rapid diagnostic overview of the vehicle condition, and identification of potential problems for repair, which can be promptly communicated to the vehicle owner or operator, thereby obtaining any necessary permissions to carry out additional vehicle service procedures and/or repairs, resulting in additional revenue for the vehicle repair shop.
In some configurations, such as a drive-through inspection lane, and depending upon which tests or measurements are being conducted on the vehicle, the process of testing the vehicle can be performed by the multi-function vehicle service system or vehicle inspection system 100 without substantial service technician interaction. In an automated configuration, the service technician is not required to sequentially initiate discrete steps in an inspection process as the tests or vehicle inspection proceeds. Instead, the test or vehicle inspection is automatically conducted by the multi-function vehicle service system or vehicle inspection system 100 as the vehicle is brought into position, and detected by sensors or cameras. Information necessary for the various diagnostic or measurement devices to acquire data is communicated directly from the multi-function vehicle service system or vehicle inspection system 100, and the results returned there to. At the conclusion of the automated tests for the vehicle, the multi-function vehicle service system or vehicle inspection system 100 resets after a suitable timeout period and is ready to receive the next vehicle for testing and/or inspection.
Once the various tests and/or procedures are completed, the multi-function vehicle service system or vehicle inspection system 100 is configured to store the results and/or generate the appropriate comprehensive reports for the customer and/or the vehicle service technician.
