     FIELD OF THE INVENTION 
     Embodiments of the invention are generally related to telematics and related technologies as may be used in vehicle monitoring and other applications, and are particularly related to a system and method for use of pattern recognition in assessing or monitoring a current status of a vehicle, such as determining when an operator or a passenger has embarked or disembarked the vehicle, and/or an operator&#39;s driving behavior. 
     BACKGROUND 
     Telematics generally refers to the integration of telecommunications and informatics, and is often described in the context of sending and receiving information about moving objects by means of telecommunication devices. A well-known use of telematics is in regard to vehicles, and with control of moving vehicles, such as haulage trucks. devices such as Global Positioning Systems (GPS) can be used to provide additional information beyond that provided by the vehicle itself. Telematics are of particular use in industries such as fleet management, which might also include tracking the location and operation of ships, trains, and planes. 
     Information about vehicle usage also has a bearing on factors such as insurance. Heavily-used vehicles are on the road more often, and this type of information is useful for the insurance industry. However telematics information such as that provided by GPS is largely macro in nature, and does not necessarily reflect the micro-conditions of day-to-day driving. As such, conventional telematics information is generally less pertinent for monitoring casual vehicle users, and is typically not intended for providing information of particular interest to insurers, such as the number of passengers in a vehicle at the time of an accident. These are the general areas that embodiments of the invention are intended to address. 
     SUMMARY OF THE DISCLOSURE 
     Disclosed herein is a system and method which uses pattern recognition in assessing or monitoring a vehicle status and/or an operator&#39;s driving behavior. A vehicle, for use by an operator or driver, can be equipped with a data collection and assessment system. The system can comprise one or more data collection devices, e.g., accelerometers, which can be used to capture data and information, or otherwise measure vehicle actions. A data communication module enables communication of the collected data and information, such as through the use of telematics, to one or more other systems, which can be local or onboard to the vehicle, or a remote system. A pattern recognition module is configured with one or more defined operating patterns, each of which operating patterns reflects either a known change in vehicle status corresponding to, e.g., when a passenger has embarked or disembarked the vehicle, or a known vehicle operating or driving behavior. Information collected as events describing a current vehicle status or a current driving behavior can be compared with the known operating patterns. In accordance with an embodiment, the information can then be used locally or communicated to an operator assessment and monitoring system or service, which can provide additional functionality, such as ensuring a driver&#39;s compliance with employment or other mandated driving requirements, or assessing a driver&#39;s suitability for insurance reasons, including, e.g., taking into account a driver&#39;s reaction to variations in the road, cornering, and other driving situations.

     DETAILED DESCRIPTION 
     Disclosed herein is a system and method which uses pattern recognition in assessing or monitoring events describing a current vehicle status, such as determining when an operator or a passenger has embarked or disembarked the vehicle, and/or events describing an operator&#39;s current driving behavior. The information can be used locally or communicated to an operator assessment and monitoring system or service, which can provide additional functionality, such as ensuring a driver&#39;s compliance with employment or other mandated driving requirements, or assessing a driver&#39;s suitability for insurance reasons, including, e.g., taking into account a driver&#39;s reaction to variations in the road, cornering, and other driving situations. 
     Although many of the illustrations provided herein describe embodiments using vehicles and accelerometers, it will be evident that the systems and techniques described herein can be used with operator-controlled devices other than vehicles, such as trains and ships, and with other types of data-collection devices. 
       FIG. 1  shows an illustration of a system which uses pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 1 , in accordance with an embodiment, a vehicle  102 , for use by an operator or driver  100 , can be equipped with a data collection and assessment system  104 . The system can comprise one or more data collection devices  106  (e.g., accelerometers or other measurement devices  110 ) that can be used to capture data and information, or otherwise measure vehicle actions. A data collection module  112  collects the data or information from the data collection devices, while a data communication module  112  enables communication of the collected data and information, such as through the use of telematics, to one or more other systems. 
     A pattern recognition module  118  is configured with one or more defined operating patterns  120 , each of which operating patterns reflects either a known change in vehicle status corresponding to, e.g. when a passenger has embarked or disembarked the vehicle, or a known vehicle operating or driving behavior. For example, when an operator embarks a vehicle on the driver&#39;s side, the vehicle responds in a physically-measurable manner (e.g., by moving downwards momentarily or tilting to one side). When a passenger then embarks the same vehicle, perhaps from an opposite side or through the rear doors, the vehicle responds in a physically-measurable manner, albeit with a different pattern. Each discernible pattern or set of events reflects a known change in the vehicle status. A sequence of patterns can reflect, as in the above example, that the vehicle, or its vehicle status, now likely includes both the operator and the passenger. Similar physically-measurable patterns can reflect when the operator or passenger leaves or disembarks a vehicle. 
     A vehicle also responds in a physically-measurable manner to operator-based driving actions, e.g. by the operator turning the vehicle sharply at a corner. This enables the system to associate other events and patterns with an operator&#39;s driving behavior. 
     Sequences of patterns can be used to reflect changes both in the vehicle status and in the operator&#39;s driving behavior over a period of time, say from the time an operator embarks the vehicle, through a series of driving maneuvers, up until the time of a later accident. 
     In accordance with an embodiment, an operator assessment and monitoring module  122  includes information about one or more vehicle operators, including for each operator an identifier (ID)  124  and additional data or information  126  describing that operator and/or their typical operating characteristics. An operator feedback module  128  can be used to provide immediate or local feedback to the operator depending on their current vehicle status and/or operator driving behavior. 
     Any resultant information, pattern matching, or driver feedback can also be remotely communicated to an external operator assessment and monitoring system or service  132 , which can provide additional functionality, such as ensuring a driver&#39;s compliance with employment or other mandated driving requirements, or assessing a driver&#39;s suitability for insurance reasons. 
       FIG. 2  shows another illustration of a system which uses pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 2 , depending on the particular implementation, a selection of the components of the system can be provided onboard or locally to the vehicle, while others of the components can be provided elsewhere separately or remotely from the vehicle, or by a third-party. For example, in accordance with an embodiment, the vehicle  140  can include a collection and assessment system  142  that comprises one or more data collection devices  144 , a data collection module  146 , a data communication module  148 , and an operator feedback module  152 . An external operator assessment and monitoring system or service  160 , which in this example is provided separately from the vehicle, can include a pattern recognition module  162  configured with one or more defined operating patterns  163 , and an operator assessment and monitoring module  164  that includes information about one or more vehicle operators, including for each operator an operator ID  166  and additional data or information  166 . 
     Different arrangements of modules/components can be provided in accordance with different embodiments to suit particular implementations. In some embodiments, the pattern recognition module can be provided onboard or locally to the vehicle, to provide immediate or local feedback to the operator depending on a current status of their vehicle and/or their current driving behavior, without a need for an external system or service. For example, a system including local feedback might determine that too many passengers have embarked the vehicle for preferred safe driving, and communicate this information to the operator prior to them starting the vehicle. 
     As further shown in  FIG. 2 , the information collected describing a current vehicle/operator status or driving pattern can be compared  170  with known operating patterns, and the results of the comparison used in providing operator feedback and/or updating operator profile data and/or providing other services such as assessment or monitoring of operator behavior  180 . 
       FIG. 3  shows another illustration of a system which uses pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 3 , depending on the particular implementation, the system can be used to assess and monitor a plurality of vehicles or their operators. In accordance with an embodiment, each vehicle  200 ,  210  comprises a data collection and assessment system  202 ,  212  that comprises one or more data collection devices  204 ,  214  (e.g., accelerometers), and a data collection module  206 ,  216 . An external operator assessment and monitoring system or service  220  that includes a pattern recognition module  222  further comprises an operator assessment and monitoring module  224  that includes information about a plurality of vehicle operators, including for each operator an identifier (ID)  226 ,  228 ,  230  and additional data or information  232 ,  234 ,  236  describing that operator or their operating characteristics. 
       FIG. 4  shows an illustration of a system which uses pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, as it may be used with a vehicle and driver, in accordance with another embodiment. As shown in  FIG. 4 , while a vehicle  250  is used, and as events happen or as time passes T 1  ( 252 ), T 2  ( 254 ), T 3  ( 256 ), current vehicle/operator data is communicated to a data collection and assessment system  260  (which as described above can be provided onboard to the vehicle or remotely via telematics). The information can then be used by or communicated to an operator assessment and monitoring system or service  262 , which can provide additional functionality, such as ensuring a driver&#39;s compliance with employment or other mandated driving requirements, or assessing a driver&#39;s suitability for insurance reasons, including, e.g., taking into account a driver&#39;s reaction to variations in the road  264 , cornering, and other driving situations. 
       FIG. 5  shows another illustration of a system which uses pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 5 , in accordance with an embodiment the vehicle  270  can be equipped with a data collection and assessment system  272 , including a data collection module  276 , data communication module  278 , and accelerometers  280  as data collection devices  274 , or similar devices used to measure changes in acceleration or direction of a vehicle. Information can be collected from a plurality of (in the illustrated example) X  282 , Y  284 , and Z  286  axis-measuring accelerometers, and collectively used to provide a current vehicle/operator data  290 . The pattern recognition module  300  can be configured with one or more defined operating patterns  302 ,  304 ,  306 , each of which reflects a known vehicle/operator status or driving pattern based on accelerometer data. The information provided regarding current vehicle/operator accelerometer-based-data can be compared with the known accelerometer-based operating patterns, and the results of the comparison used providing of operator feedback and/or updating of operator profile data and/or other services such as assessment or monitoring of operator behavior. 
       FIG. 6  shows an illustration of examples of data to be used with pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 6 , in accordance with an embodiment wherein the data collection and assessment system utilize accelerometers, or similar devices used to measure changes in acceleration or direction of a vehicle, information can be collected from a plurality of X, Y, and Z axis-measuring accelerometers ( 320 ,  322 ,  324 ), and collectively used to provide a current vehicle/operating data  326 . For example, as described above, when an operator or passenger embarks or disembarks a vehicle on the driver&#39;s side, the vehicle responds in a physically-measurable manner. In accordance with an embodiment, the accelerometers can detect the minor accelerations in the vehicle when a person enters the car and closes the door, takes a corner or brakes sharply, or drives in a manner considered unsafe. The information collected describing a current vehicle/operator status or driving pattern can be compared with known operating patterns, and the results of the comparison used in providing operator feedback and/or updating operator profile data and/or providing other services such as assessment or monitoring of operator behavior  328 . 
     As further shown in  FIG. 6 , each of the graphs  320 ,  322 ,  342  can show accelerations in the X, Y, and Z axes respectively for a stationary vehicle. Each time a passenger enter/exits the vehicle and the engine is on, the system registers a low amplitude up and down motion hovering around value 128+−2 units for a non-event average, followed by a minor perturbation simultaneous in all three axes where the amplitude jumps above the “normal” amplitude. The system can recognize these up and down characteristics as a known pattern. 
     In accordance with an embodiment, further discernment can include, e.g. recognizing minor variations in the pattern to determine the vehicle being pushed to the left, representative of an entry on the right side; or the vehicle being pushed forward and to the right, representative of an entry to the left-rear side. Information such as this can be used to ensure a driver&#39;s compliance with employment or other mandated driving requirements, or assessing a driver&#39;s suitability for insurance reasons, including, e.g. preventing insurance fraud, detecting patterns and then using occurrences of said patterns when they occur, to say with some level of confidence (a confidence coefficient) that an event of certain type occurred, which is particularly useful for post-accident investigations. 
       FIG. 7  shows a flowchart of a method of using pattern recognition in assessing or monitoring a vehicle status or an operator&#39;s driving behavior, in accordance with an embodiment. As shown in  FIG. 7 , at step  350 , one or more known operating patterns are defined for use by the pattern recognition module. At step  352 , while the vehicle is being used, current vehicle operating data is collected via data collection devices (e.g. accelerometers), for one or more operators. At step  254 , the current vehicle/operator data is compared with operating patterns using pattern recognition module, to assess or monitor current operator. At step  356 , the system provides operator feedback and/or updates of operator profile data and/or provides other services such as assessment or monitoring of operator behavior. 
     In accordance with various embodiments, the above-described systems and methods can be employed in a variety of use cases. For example, the system can be used in conjunction with an automatic rescue or emergency dispatch system, wherein information about the number of passengers in a vehicle can be automatically communicated to a central rescue or emergency service. As another example, the system can be used in conjunction with systems for parental or otherwise tracking the habits of younger drivers, e.g. to ensure that the number of passengers within a vehicle is kept within certain predefined limits, or for vehicle insurance purposes.
