Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0001]    The present invention relates generally to the field of real-time asset tracking via proprietary Ultra Wide Band (UWB) radio frequency technology. More specifically, the present invention relates to a real-time asset tracking, reconciliation and workflow system for use in the retail automotive industry. 
       Description of Prior Art 
       [0002]    Automobile dealerships are challenged with the laborious task of managing large inventories. As a result, corresponding dealerships are unable to produce timely, accurate inventory reconciliations, thus degrading the integrity of the information. Outdated inventory reports can cause many problems for the dealership as it relates to manufacturer, floor plan credit, incentives, theft, and credibility to the customer. There are many cases of inaccurate reporting of assets that may under or overstate the dealership&#39;s balance sheet and credit worthiness that expose all parties responsible for signing financials. These issues are exacerbated by the increasing number of vehicles on the lot and their availability through resellers via online auction houses and listings. 
         [0003]    An increasing factor contributing to this problem are the number of vehicles for sale and the short turnover period. What used to be a 90 day carrying cycle can easily be cut to 60 to 45 based upon buying patterns of internet sales. Moreover, the customers are armed with a wealth of knowledge and alternatives to the vehicles available at the dealership. Inaccurate information will result in a customer purchasing elsewhere. 
         [0004]    Automobile dealerships process new and used vehicles prior to having the vehicles ready for sale. The processing can vary for each vehicle, or consist of standard processing steps for each vehicle. Keeping track of the steps needed and completed to process each vehicle is an information challenge. The work performed requires data such as: when the vehicle arrived on premises; who checked-in the vehicle and set its process path; what process steps are variable for each vehicle versus the standard path for get-ready; and when is the vehicle ready for sale. Unison is a workflow software which easily captures this data and makes logical reports and sends alerts when bottleneck parameters are exceeded. Unison along with tracking the movement and time of each vehicle provides a solution to the processing management challenges, including reports, vendor involvement, and accounting integration, resulting in ideal software for the job. 
       SUMMARY OF THE INVENTION 
       [0005]    The present invention provides automotive dealerships with a smart network of tags that are installed on the vehicle&#39;s windshield. The smart tag transmits the Vehicle Identification Number (VIN) and location data to a centralized base station via a combination of Ultra Wide Band (UWB) and 2.4 GHz wireless technologies. A network of UWB and 2.4 GHz enabled anchors calculate location data and relay this data to a centralized basestation. Each anchor is capable of communicating and relaying information on behalf of other anchors. Hence, the information from anchor A could be derived from anchors X, Y and Z. The tags in consort with the anchors are capable of localizing an accurate position using an array of Multilateration (MLAT) technologies. The MLAT method used is defined by the best fit for the particular deployment. The base station, in turn, transmits all vehicle location data to a web based application via a cellular connection. This minimizes the amount of infrastructure required to deploy a turnkey solution. The present invention provides personnel with real-time information on the availability and location of any vehicle on the lot. This information can be accessed via API, web browser, cell phone, tablet or other mobile computing platform. 
         [0006]    According to one presently preferred embodiment of the invention, there is provided an inventory tracking, reconciliation and work flow system for use in connection with motor vehicles comprising a locator tag associated with a motor vehicle, a plurality of anchors and a base station.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0024]    For purposes of promoting and understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention that would normally occur to one skilled in the art to which the invention relates. 
         [0025]    The present invention is comprised of several components and subsystems which makeup the entire invention. The present invention provides long and short range radio frequency tags  40   a,    40   b,    40   c  for use by retail automotive dealerships and auction facilities that all allows them to locate vehicles  110   a,    110   b,    110   c  in real-time. Conveniently, a comptroller may employ the present invention to locate a vehicle that is showing up as a discrepancy in accounting. In one particular embodiment, the present invention is capable of locating the discrepancy on an offsite lot. Not only is this system useful for detecting the presence of a vehicle  110  on the lot  100 , but it can also be used to determine the location of a vehicle  110  on the lot  100  and its proximity to or presence at a particular station, such as inspection station  50 , detailing station  52  or sales station  54 . 
         [0026]    FIG. 1  shows one preferred embodiment of an inventory tracking, reconciliation and workflow system  10  used in connection with one or more vehicles  110   a,    110   b,    100   c,  etc. on a lot  100  of a retail automotive dealership. The system  10  includes a base station  20 , a plurality of anchors, preferably at least three ( 3 ) anchors  30   a,    30   b,    30   c,  and one or more locator tags  40   a,    40   b,    40   c,  etc. associated with corresponding one or more vehicles  110   a,    110   b,    100   c,  etc. 
         [0027]    As best shown in  FIG. 2 , the base station  20  is comprised of a cellular transceiver  22  and 2.4 GHz wireless transceiver  24  that relay received messages from one or more of the anchors  30   a,    30   b,    30   c  to the web based application. The base station  20  may be positioned anywhere on or off the lot  100  so long as it is in range of one or more of the anchors  30   a,    30   b,    30   c . Preferably, the base station is positioned at a central location or in an office building on the lot  100 . The base station  20  also includes a micro-controller  21  coupled to and controlling the cellular transceiver  22  and wireless transceiver  24 . The base station  20  receives power via a power input  23 . Alternative means for transmitting the data to a remote server, such as antenna  25 , USB  26 , CANbus  27  and/or Ethernet  28  connectors may also be provided. 
         [0028]    The three or more anchors  30   a,    30   b,    30   c  are positioned at locations remote from one another on the lot  100 . As best shown in  FIG. 3 , each anchor  30  includes an ultra-wide band (UWB) transceiver  32   a  and 2.4 GHz wireless transceiver  32   b  that participate in the calculation of location of the tags  40   a,    40   b,    40   c.  The anchors  30   a,    30   b,    30   c  participate in a mesh network  60  which is responsible for reliably transmitting vehicle location to the base station  20 . The anchor  30  also includes a micro-controller  31  which is coupled to the UWB transceiver  32   a  and the wireless transceiver  32   b . The anchor  30  receives power via a power input  33 . 
         [0029]    Each anchor  30  may also include a 9-axis inertial motion sensor  34 , which includes a 3-axis accelerometer  34   a , a 3-axis gyroscope  34   b , and a 3-axis magnetometer  34   c . The accelerometer  34   a  and gyroscope  34   b  provide information about accelerations in all three directions, and rotations around each axis. To account for drift due to the build up of small errors in each axis over time, a magnetometer  34   c  is also included to track the absolute change in position and orientation much more accurately. Alternatively, the inertial motion sensor  34  may consist of an attitude and heading reference system (AHRS) that consists of sensors on three axes that provide attitude information including roll, pitch and yaw. The AHRS may consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers on all three axes. Each anchor  30  also includes an altimeter/barometer  36  may also be connected to the micro-controller  31  to provide data with regard to the altitude of the anchor  30 . This information is particularly useful where vehicles are located in a multi-level parking garage or similar facility. 
         [0030]    Each vehicle  110  is fitted with a locator tag  40  which is used to track the presence and location of the vehicle  110  on the lot  100 . The locator tag  40  is the device that is affixed to the vehicle  110  and is responsible for beaconing location and movement information. The tag is equipped with a wide array of sensors to notify of theft, tampering movement, and abuse. As best shown in  FIG. 4 , the locator tag  40  includes a micro-controller  41 , preferably an Atmel SAM4S Cortex-M4 micro-controller, that communicates with several onboard subsystems, including at least a tampering subsystem, a security subsystem, and a location subsystem. The micro-controller  41  is coupled to a UWB transceiver  42  which is configured to transmit location and movement information to the one or more of the anchors  30   a,    30   b,    30   c.  The micro-controller  41  and other components of the locator tag  40  receive power via a battery  43 . As best shown in  FIG. 5B , the battery may preferably be a coin-cell type battery, which, in the present setting, has an expected life of approximately six (6) months. 
         [0031]    The tampering sub system is comprised of an infrared emitter and detector  48  that is tuned to an adhesive backing  62  that reflects a particular spectrum of light. The adhesive backing  52  also affixes the locator tag  40  to the windshield. As best shown in  FIG. 5A  and  FIG. 5B , the locator tag  40  is located within a weatherproof housing  60  having an upper housing  60   a  and a lower housing  60   b.  The housing  60  is formed of a material that is impact and water resistant. Preferably, a material that is rated IP67 or higher is used to protect the locator tag  40  from dust and against the effect of immersion between 15 cm and 1 m. The lower housing  60   b  is preferably formed of an infrared transmissive polycarbonate material that allows the emitted infrared light from the infrared emitter  48  to pass through the bottom of the case and to reflect back from the adhesive  62 . Obscuration or removal of the adhesive  62  is detected by the infrared detector  48  and triggers a notification to the network  70 . 
         [0032]    The security subsystem is comprised of a 9-axis inertial motion sensor  44 , which includes a 3-axis accelerometer  44   a , a 3-axis gyroscope  44   b , and a 3-axis magnetometer  44   c . The accelerometer  44   a  and gyroscope  44   b  provide information about accelerations in all three directions, and rotations around each axis. To account for drift due to the build up of small errors in each axis over time, a magnetometer  44   c  is also included to track the absolute change in position and orientation much more accurately. The components of the security subsystem can also act to extend battery life by shutting down power to the systems of the locator tag  40  when movement has not been detected for a predetermined period of time. Alternatively, the inertial motion sensor  44  may consist of an attitude and heading reference system (AHRS) that consists of sensors on three axes that provide attitude information including roll, pitch and yaw. The AHRS may consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers on all three axes. The locator tag  40  may also include an altimeter/barometer  46  may also be connected to the micro-controller  41  to provide data with regard to the altitude of the locator tag  40  and the corresponding vehicle  110 . This information is particularly useful where vehicles are located in a multi-level parking garage or similar facility. 
         [0033]    The security subsystem works in consort with the tampering subsystem to determine removal of the tag  40 . The security subsystem is also responsible for reporting vehicle movement as well as hard braking and acceleration. The security subsystem is capable of detecting vehicle motion, including opening and closing of doors to determine access to the vehicle, or inclination and declination of vehicle in the scenario where wheels and tires may be stolen. The components of the security subsystem may also be used to measure and log hard braking and acceleration to determine vehicle abuse. Motion is used to determine reporting interval of the tag in order to conserve battery life. Motion sensing is used in consort with the IR sensor to detainee tag tampering in the event the tag is removed from the vehicle. 
         [0034]    The location subsystem is comprised of a UWB radio transceiver  42  which is responsible for transmitting a beacon when the vehicle senses movement and or predetermined timeout interval whichever occurs first. This beacon is used to calculate the exact location of the tag  40  relative to the anchors  30   a,    30   b,    30   c.    
         [0035]    The anchors  30   a,    30   b,    30   c  are capable of meshing together with one another, and with the base station  20  to form a wireless mesh network (WMN)  70 , wherein one anchor  30   a  is capable of relaying information on behalf of other anchors  30   b,    30   c.  When a specific vehicle on the network transmits its location the route to the base station  20  may change. The mesh network  70  created from a number of anchors  30   a,    30   b,    30   c  acts as a resilient network to guarantee delivery of the information. The purpose of this functionality is to expand the footprint of the network, extend battery life and ensure self repairing/healing of less dense areas of the network. The mesh created by present invention also acts as a point to multi-point ranging field from which location of the asset can be ascertained via multilateration (MLAT). 
         [0036]    The system is set up, or commissioned, by first placing the base station  20  at a location and then placing the three or more anchors  30   a,    30   b,    30   c  at locations on the lot  100 . Initially, the coordinates of one of the anchors, primary anchor  30   a  for example, must be known. The primary anchor  30   a  then communicates with secondary anchor  30   b  and tertiary anchor  30   c  to determine the distances between each of the anchors, respectively. 
         [0037]    The distances between anchors can be determined using a variety of known ranging methods including Time of Flight (TOF) ranging, two-way ranging, Time Difference of Arrival (TDOA), angle of arrival, or other MLAT techniques. Once the location of all three anchors  30   a ,  30   b  and  30   c  are determined, a satellite map may be overlaid onto the now known coordinates of the anchors and the locations of the various stations  50 ,  52 ,  54  determined. 
         [0038]    Using MLAT, the location of a locator tag  40  is determined in two phases. MLAT is a two phase process where range measurements between a device with unknown location and three or more reference devices are used to estimate a location in two dimensions. The first phase involves measuring a relationship between nodes (e.g., distance and angle). The second phase uses these relationships to estimate location. Radio frequency (RF) received signal strength (RSS) measurements are commonly used to estimate range, but the accuracy of this technique is poor even in the best of conditions. Accordingly, the use of ultra-wideband (UWB) RF ranging is preferred. The second phase takes three or more of these ranges (for example, the ranges between anchor  30   a  and locator  40 , between anchor  30   b  and locator  40 , and between anchor  30   c  and locator  40 ) and, utilizing geometric computer algorithms, calculates the location of the locator  40 . When used in connection with the present invention, UWB RF ranging can provide the location of the locator tag within 10 cm and can accurately detect locators at distances of 100 meters. The accuracy can be further enhanced by linking to a smartphone GPS. 
         [0039]    Once the system has been commissioned, the locator tag  40  associated with each vehicle can be provisioned. In order to extend battery life, a locator tag  40  that is located on a vehicle  110  generally remains in a powered down state until activation is triggered. Activation can be triggered by an internal clock that would cause the locator tag  40  to transmit a signal at regular intervals, for example, every 10 seconds. The locator tag  40  can also be activated to transmit a signal when the inertial motion sensor  44  senses movement, or when the infra-red sensor  48  detects light indicating the housing  50  and/or mobile tag  40  has been tampered with. In the latter two instances, the signal would be transmitted at a higher frequency to indicate tampering or activity. 
         [0040]    When the locator tag  40  is activated, it transmits an ultra wide band (UWB) RF signal which is received at each of the anchors  30   a,    30   b,    30   c.  Using one or more of the ranging techniques discussed above, the location of the locator tag  40  can be determined based, in part, on the distances between the locator tag  40  and each of the anchors  30   a,    30   b,    30   c.  One or more of the anchors  30   a,    30   b,    30   c  can then transmit the location information of the locator tag  40  to the location engine, which can either store the information about the locations of multiple locator tags. With the additional information provided by the satellite map overlay, algorithms can be created to determine whether a vehicle  100  having a locator tag  40  is at a particular station, such as inspection station  50 , detailing station  52  or sales station  54 . 
         [0041]    The present invention provides a form of Peer to Peer n (P2Pn) Firmware Over The Air (FOTA) upgrades. This method of upgrading firmware allows the wave of firmware requests to be radiated outward from a cascading epicenter. As tags further from the epicenter become upgraded, they will source their FOTA records from tags in local proximity, thus propagating the wave until the entire network is upgraded. 
         [0042]    Illustration A depicted below demonstrates how the tags receive firmware from neighboring anchors in the most efficient manner possible. Tag 0 has current firmware, each subsequent tag has one less line of firmware that they can request from the next closest anchor to the base station. This is a simple linear illustration that models how the tags would work in a network of many thousands. 
         [0043]    Illustration A. 
         [0044]    Tag 0: 1111111111 
         [0045]    Tag 1: 1111111110 
         [0046]    Tag 2: 1111111100 
         [0047]    Tag 3: 1111111000 
         [0048]    The present invention is capable of Firmware Over The Air (FOTA) upgrades. FOTA enables the smart tags to query neighboring devices for firmware versions. If neighboring tags have a newer version of firmware, a FOTA session is started and the new firmware is torrented from the neighboring tags internal flash. The reason for this feature is to minimize numerous downloads of firmware from the base station. Once the base station receives new firmware it is capable of broadcasting out the current version to all tags. This technology allows the mesh network to be self aware or upgraded on demand based upon commands received from the base station. 
         [0049]    The present invention is capable of remote terminal sessions that allow system administrators to remotely communicate with the tags via the cellular base station. Network maintenance tuning can be achieved via the remote terminal. 
       EXAMPLES 
       [0050]    Example Reconciliation . . . 
         [0051]    Managing large amounts of inventory is too laborious to manage all at once. The present invention allows dealerships to manage their inventories by exception in real-time. A perpetual view of exceptions is always available. Every possible real-time combination of cross-referenced exception via Physical, General Ledger, Floor Plan, Manufacturer, etc. 
         [0052]    Example Workflow . . . 
         [0053]    Vehicle processing poses many challenges for the dealership. The smart tag automatically provisions the vehicle into the dealership workflow system. The workflow system then triggers and delegates other tasks depending on the current state of the vehicle. For example, a new vehicle checking in may require PDI, booked to the general ledger, detail, etc. Vehicles departing premises for an offsite sale or storage may show up on a departure report that needs reconciliation. Unauthorized access to vehicles can trigger notifications to management. 
         [0054]    Example Asset Validation . . . 
         [0055]    Asset validation is one of most important points of risk mitigation for a dealership. Banks want to know the vehicles they are floor planning are physcially on the lot. Not having accurate inventories can cost the dealership their floorplan credit rating or banking relationship altogether. Dealerships need to know what cars are being driven in order to purchase more effieciently. Management needs to be alerted of suspicious activity. 
         [0056]    Example Asset Location . . . 
         [0057]    The monthly cycle of inventory always results in discrepancies. These discrepancies need to be tracked down by dealership personnel for asset validation purposes. The present invention provides personnel with the tools to quickly locate the vehicle on the lot or report to them that the vehicle has departed the premises. The present invention also helps sales associates to locate a particular vehicle inquiry by a customer. 
         [0058]    Monthly floor plan reconciliations done by the bank require tracking down vehicles that are reported sold but still booked in inventory. The location services of the present invention speeds this process up tremendously. 
         [0059]    As described above, according to a preferred embodiment of the present invention, the wireless communications use an 802.15.4-2011 based UWB radio. Alternatively, the RF transceiver could be a WiFi transceiver configured to transmit and receive data using IEEE 802.11 protocols; a Zigbee module configured to transmit and receive data using IEEE 802.15.4 protocols; a Bluetooth® low energy (BLE) transceiver or other equivalent RF transmission technology that may now, or in the future be utilized. As a further alternative, the wireless mesh network could consist of hardwiring between the various anchors and base station. 
         [0060]    This detailed description, and particularly the specific details of the exemplary embodiment disclosed, is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modifications will become evident to those skilled in the art upon reading this disclosure and may be made without departing from the spirit or scope of the claimed invention.
