`ABSTRACT
`
`A method and system of determining a cost of automobile
`insurance based upon monitoring, recording and communi-
`cating data representative of operator and vehicle driving
`characteristics. The cost is adjustable retrospectively and
`can be prospectively set by relating the driving characteris-
`tics to predetermined safety standards. The method com-
`prises steps of monitoring a plurality of raw data elements
`representative of an operating state of the vehicle or an
`action of the operator. Selected ones of the raw data ele-
`ments are recorded when the ones are determined to have an
`identified relationship to safety standards. The selected ones
`are Consolidated for processing against an insurer profile and
`for identifying a surcharge or discount to be applied to a base
`cost of automobile insurance. A final cost is produced from
`the base costs and the surcharges or discounts.

`MOTOR VEHICLE MONITORING SYSTEM
`FOR DETERMINING A COST OF
`INSURANCE
`
`BACKGROUND OF THE INVENTION
`
`invention relates to data acquisition and
`The present
`processing systems. and particularly to a system for moni-
`toring motor vehicle operational characteristics and driver
`behavior to obtain increased amounts of data relating to the
`safety of use for purposes of providing a more accurate
`determination of a cost of insurance for the vehicle.
`
`Conventional methods for determining costs of motor
`vehicle insurance involve gathering relevant historical data
`from a personal interview with the applicant for the insur-
`ance and by referencing the applicant’s public motor vehicle
`driving record that is maintained by a governmental agency.
`such as a Bureau of Motor Vehicles. Such data results in a
`classification of the applicant to a broad actuarial class for
`which insurance rates are assigned based upon the empirical
`experience of the insurer. Many factors are relevant to such
`classification in a particular actuarial class. such as age. sex.
`marital status. location of residence and driving record.
`The current system of insurance creates groupings of
`vehicles and drivers (actuarial classes) based on the follow—
`ing types of classifications.
`Vehicle:
`
`25
`
`Age;
`manufacturer. model; and
`value.
`Driver:
`
`Age;
`sex;
`
`marital status;
`driving record (based on government reports).
`violations (citations);
`at fault accidents; and
`place of residence.
`Coverage:
`Types of losses covered.
`liability.
`uninsured motorist.
`comprehensive. and
`collision;
`liability limits; and
`deductibles.
`The classifications. such as age. are further broken into
`actuarial classes. such as 21 to 24.
`to develop a unique
`vehicle insurance cost based on the specific combination of
`actuarial classes for a particular risk. For example.
`the
`following information would produce a unique vehicle
`insurance cost.
`
`Vehicle:
`
`Age
`manufacturer. model
`value

`$500./$500.
`
`A change to any of this information would result in a
`difierent premium being charged. if the change resulted in a
`different actuarial class for that variable. For instance. a
`change in the drivers’age from 38 to 39 may not result in a
`different actuarial class. because 38 and 39 year old people
`may be in the same actuarial class. However. a change in
`driver age from 38 to 45may result in a difierent premium
`because of the change in actuarial class.
`Current insurance rating systems also provide discounts
`and surcharges for some types of use of the vehicle. equip-
`ment on the vehicle and type of driver. Common surcharges
`and discounts include:
`Surcharges:
`Business use.
`Discounts:
`
`Safety equipment on the vehicle
`airbags. and
`antilock brakes;
`theft control devices
`passive systems (eg. ‘The Club”). and
`alarm system; and
`driver type
`good student. and
`safe driver (accident free).
`A principal problem with such conventional insurance
`determination systems is that much of the data gathered
`from the applicant in the interview is not verifiable. and even
`existing public records contain only minimal information.
`much of which has little relevance towards an assessment of
`the likelihood of a claim subsequently occurring. In other
`words. current rating systems are primarily based on past
`realized losses. None of the data obtained through conven-
`tional systems necessarily reliably predicts the manner or
`safety of future operation of the vehicle. Accordingly. the
`limited amount of accumulated relevant data and its minimal
`evidential value towards computation of a fair cost of
`insurance has generated a long-felt need for an improved
`system for more reliably and accurately accumulating data
`having a highly relevant evidential value towards predicting
`the actual manner of a vehicle's future operation.
`Many types of vehicle operating data recording systems
`have heretofore been suggested for purposes of maintaining
`an accurate record of certain elements of vehicle operation.
`Some are suggested for identifying the cause for an accident.
`others are for more accurately assessing the efliciency of
`operation. Such systems disclose a variety of conventional
`techniques for recording vehicle operation data elements in
`a variety of data recording systems. In addition. it has also
`been suggested to provide a radio communication link for
`such infonnation via systems such as a cellular telephone to
`provide immediate communication of certain types of data
`elements or to allow a more immediate response in cases
`
`Page 000008

`such as theft. accident. breadodown or emergency. It has
`even been suggested to detect and record seatbelt usage to
`assist in determination of the vehicle insurance costs (US.
`Pat. No. 4.667.336}.
`The various forms and types of vehicle operating data
`acquisition and recordal systems that have heretofore been
`suggested and employed have met with varying degrees of
`success for their express limited purposes. All possess
`substantizd defects such that they have only limited eco-
`nomical and practical value for a system intended to provide
`an enhanced acquisition. recordal and communication sys-
`tem of data which would be both comprehensive and reliable
`in predicting an accurate and adequate cost of insurance for
`the vehicle. Since the type of operating information acquired
`and recorded in prior art systems was generally never
`intended to be used for determining the cost of vehicle
`insurance.
`the data elements that were monitored and
`recorded therein were not directly related to predetermined
`safety standards or the determining of an actuarial class for
`the vehicle operator. For example. recording data character-
`istics relevant to the vehicle‘s operating efficiency may be
`completely unrelated to the safety of operation of the
`vehicle. Further.
`there is the problem of recording and
`subsequently compiling the relevant data for an accurate
`determination of an actuarial profile and an appropriate
`insurance cost therefor.
`
`Current motor vehicle control and operating systems
`comprise electronic systems readily adaptable for modifica-
`tion to obtain the desired types of information relevant to
`determination of the cost of insurance. Vehicle tracking
`systems have been suggested which use communication
`links with satellite navigation systems for providing infor-
`mation describing a vehicle’s location based upon naviga-
`tion signals. When such positioning information is com-
`bined with roadmaps in an expert system. vehicle location is
`ascertainable. Mere vehicle location. though. will not pro
`vide data particularly relevant to safety of operation unless
`the data is combined with other relevant data in an expert
`system which is capable of assessing whether the roads
`being driven are high-risk or low-risk with regard to vehicle
`safety.
`The present invention contemplates a new and improved
`motor vehicle monitoring. recording and communication
`system. which primarily overcomes the problem of deter-
`mining cost of vehicle insurance based upon data which
`does not take into consideration how a specific vehicle is
`operated. The subject invention will base insurance charges
`with regard to current material data representative of actual
`driving characteristics of the vehicle and driver operation to
`provide a classification rating of the operator and the vehicle
`in an actuarial class which has a vastly reduced rating error
`over conventional insurance cost systems. Additionally. the
`present invention allows for frequent (monthly) adjustment
`to the cost of coverage because of the changes in operator
`behavior and driving patterns. This can result in automobile
`insurance charges that are readily controllable by individual
`operators. The system is adaptable to current electronic
`operating systems.
`tracking systems and communication
`systems for the improved extraction of selected insurance
`related data.
`
`BRIEF SUMMARY OF THE INVENTION
`
`In accordance with the present invention. there is dis-
`closed a method of determining a cost of automobile insur-
`ance based upon monitoring. recording and communicating
`data representative of operator and vehicle driving
`characteristics. whereby the cost is adjustable by relating the
`
`4
`driving characteristics to predetermined safety standards.
`The method is comprised of steps of monitoring a plurality
`of raw data elements representative of an operating state of
`a vehicle or an action of the operator. Selected ones of the
`plurality of raw data elements are recorded when they are
`determined to have an identified relationship to the safety
`standards. The recorded elements are consolidated for pro-
`cessing against an insured profile and for identifying a
`surcharge or discount
`to be applied to a base cost of
`automobile insurance. The total cost of insurance obtained
`from combining the base cost and surcharges or discounts is
`produced as a final cost to the operator.
`In accordance with another aspect of the present
`invention.
`the recording comprises identifying a trigger
`event associated with the raw data elements which has an
`identified relationship to the safety standards so that trigger
`information representative of the event is recorded.
`In accordance with a more limited aspect of the present
`invention.
`the method comprises a step of immediately
`communicating to a central control station via an uplink.
`information representative of the trigger event and recording
`response information generated by the control station.
`In accordance with yet another aspect of the present
`invention. the method comprises steps of generating calcu-
`lated data elements and derived data elements from the raw
`data elements. and accumulating the calculated and derived
`data elements in a recording device.
`The present invention will use information acquired from
`the vehicle to more accurately assess vehicle usage and
`thereby derive insurance costs more precisely and fairly.
`Examples of possible actuarial classes developed from
`vehicle provided data include:
`Driver:
`
`Total driving time in minutes by each driver of the insured
`vehicle;
`number of minutes driving in highllow risk locations
`(high/low accident areas);
`number of minutes of driving at high/low risk times (rush
`hour or Sunday afternoon);
`safe driving behavior.
`using seat belts.
`use of turn signals.
`observance of speed limits. and
`observance of traffic control devices;
`number of sudden braking situations; and
`number of sudden accelmation situations.
`Vehicle:
`
`Location vehicle is parked at night (in garage.
`driveway. on street);
`and
`
`in
`
`location vehicle is parked at work (high theft locations.
`etc.).
`These new and more precise actuarial classes are consid-
`ered to be better predictors of loss because they are based on
`actual use of the vehicle and the behaviors demonstrated by
`the driver. This will allow the consumers unprecedented
`control over the ultimate cost of their vehicle insurance.
`In accordance with the present invention. additional dis-
`counts and surcharges based on data provided by the insured
`vehicle will be available. Examples of surcharges and dis-
`counts based on vehicle provided data include:
`Surcharges:
`Excessive hard braking situations occurring in high risk
`locations; and
`intermittent use of a safety device. such as seat belts.
`
`Page 000009
`
`
`
`5.797.134
`
`Discounts:
`
`5
`
`Regular selection of low/high risk routes of travel;
`regular travel at low/'l1igh risk times;
`significant changes in driving behavior that results in a
`lower risk:
`vacation discount when the vehicle is not used:
`regular use of safety devices: and
`unfailing observance of speed limits.
`There is some overlap between the use of actuarial classes
`and discounts and surcharges, Until data has been gathered
`and analyzed it is not possible to determine which vehicle
`provided data will be used to determine actuarial classes and
`which will be used for surcharges or discounts.
`One benefit obtained by use of the present invention is a
`system that will provide precise and timely information
`about the current operation of an insured motor vehicle that
`will enable an accurate determination of operating
`characteristics. including such features as miles driven. time
`of use and speed of the vehicle. This information can be used
`to establish actual usage based insurance charges. eliminat-
`ing rating errors that are prevalent in traditional systems and
`will result in vehicle insurance charges that can be directly
`controlled by individual operators.
`It is another benefit of the subject invention that conven-
`tional motor vehicle electronics are easily supplemented by
`system components comprising a data recording. a naviga-
`tion system and a communications device to extract selected
`insurance relevant data from the motor vehicle.
`It is yet another object of the present invention to generate
`actuarial classes and operator profiles relative thereto based
`upon actual driving characteristics of the vehicle and driver.
`as represented by the monitored and recorded data elements
`for providing a more knowledgeable. enhanced insurance
`rating precision.
`The subject new insurance rating system retrospectively
`adjusts and prospectively sets premiums based on data
`derived from motor vehicle operational characteristics and
`driver behavior through the generation of new actuarial
`classes determined from such characteristics and behavior.
`which classes heretofore have been unknown in the insur-
`ance industry. The invention comprises an integrated system
`to extract via multiple sensors. screen. aggregate and apply
`for insurance rating purposes. data generated by the actual
`operation of the specific vehicle and the insured user/driver.
`Other benefits and advantages of the subject new vehicle
`insurance cost determination process will become apparent
`to those skilled in the art upon a reading and understanding
`of the specification.

`DETAILED DESCRIPTION OF THE
`INVENTION
`
`Referring now to the drawings. wherein the showings are
`for purposes of illustrating the preferred embodiments of the
`invention only and not for purposes of limiting same. the
`FIGURES show an apparatus and method for monitoring.
`recording and communicating insurance related data for
`determination of an accurate cost of insurance based upon
`evidence relevant to the actual operation and in particular
`the relative safety of that operation. Generally. a vehicle user
`is charged for insurance based upon statistical averages
`related to the safety of operation based upon the insurer’s
`experience with other users who drive similar vehicles in a
`similar geographic area. The invention allows for the mea-
`sure of the actual data while the motor vehicle is being
`driven. Such data measurement will allow the vehicle user
`to directly control his/her insurance costs by operating the
`vehicle in a manner which he/she will know will evidence
`superior safety of operation and a minimal risk of generation
`of an insurance claim. Examples of data which can be
`monitored and recorded include:
`l.Actual miles driven:
`2.'I‘ypes of roads driven on (high risk vs. low risk); and.
`3.Safe operation of the vehicle by the vehicle user
`through:
`A. speeds driven.
`B. safety equipment used. such as seat belt and turn
`signals.
`time of day driven (high congestion vs.
`congestion).
`D. rate of acceleration.
`E. rate of braking.
`F. observation of traffic signs.
`With reference to FIG. 3. an exemplary motor vehicle is
`shown in which the necessary apparatus for implementing
`the subject invention is included. An on-board computer 300
`monitors andrecords various sensors and operator actions to
`acquire the desired data for determining a fair cost of
`insurance. Although not shown therein. a plurality of oper-
`ating sensors are associated with the motor vehicle to
`monitor a wide variety of raw data elements. Such data
`elements are communicated to the computer through a
`connections cable which is operatively connected to the
`vehicle data bus 304 through an SAE-Jl978 connector. or
`OBD—l1 connector or other vehicle sensors 306. A driver
`input device 308 is also operatively connected to the com-
`puter 300 through connector 307 and cable 302. The com-
`puter is powered through the Car battery 310 or a conven-
`tional generator system (not shown). Tracking of the vehicle
`for location identification can be implemented by the com-
`puter 300 through navigation signals obtained from a GPS
`(global positioning system) antenna or other locating system
`312. The communications link to a central control station is
`
`low

`C.
`
`accomplished through the cellular telephone. radio. satellite
`or other wireless communication system 314.
`FIG. 4 provides the block diagram of the in—vehicle
`computer system. The computer 300 is comprised of four
`principal components. an on-board data storage device 402.

`an input/output subsystem 404 for communicating to a
`variety of external devices. a central processing unit and
`memory device 406 and a real time operating kernel 408 for
`controlling the various processing steps of the computer
`300. The computer 300 essentially communicates with three
`on—board vehicle devices for acquisition of information
`representative of various actual vehicle operating character-
`istics. A driver input console 410 allows the driver to input
`data representative of a need for assistance or for satisfaction
`of various threshold factors which need to be satisfied before
`the vehicle can be operated. The physical operation of the
`vehicle is monitored through various sensors 412 in opera-
`tive connection with the vehicle data bus. While additional
`sensors 414 not normally connected to the data bus can be
`in direct communication with the computer 300 as will
`hereinafter be more fully explained.
`The vehicle is linked to an operation control center 416 by
`a communications link 418. preferably comprising a con-
`ventional cellular telephone interconnection. A navigation
`sub-system 420 receives radio navigation signals from a
`GPS 422.
`The type of elements monitored and recorded by the
`subject invention comprise raw data elements. calculated
`data elements and derived data elements. These can be
`broken down as follows:

`sudden rotation of vehicle:
`
`sudden loss of tire pressure;
`driver identification (through voice recognition or code or

`Derived Data Elements:
`
`vehicle speed in excess of speed limit;
`observation of traffic signals and signs;
`road conditions:
`tratfic conditions: and
`
`vehicle position.
`This list includes many. but not all. potential data elements.
`With particular reference to FIG. 1. a flowchart generally
`illustrating the data gathering process of the subject inven-
`tion is illustrated. Such a process can be implemented with
`conventional computer programming in the real time oper-
`ating kernel 408 of the computer 300. The process is
`identified with initially a begin step 100 (key in ignition?)
`and a check of whether the vehicle is operating at step 102.
`If the vehicle is not operating a reverification occurs every
`two (2) minutes as shown at step 104. It should be noted that
`the computer is continually powered by at least the vehicle
`battery 310 (FIG. 3). but it can be appreciated that during
`operation the generator (not shown) will supply the energy.
`If the vehicle is operating. then there is a step of recording
`sensor information 106. The recording comprises monitor-
`ing a plurality of raw data elements. calculated data elements
`and derived data elements as identified above. Each of these
`is representative of an operating state of the vehicle or an
`action of the operator. Select ones of the plurality of data
`elements are recorded when the ones are determined to have
`an identified relationship to the safety standards. For
`example. vehicle speed in excess of a predetermined speed
`limit will need to be recorded but speeds below the limit
`need only be monitored and stored on a periodic basis. The
`recording may be made in combination with date. time and
`location. Other examples of data needed to be recorded are
`excessive rates of acceleration or frequent hard braking.
`The recording process would be practically implemented
`by monitoring and storing the data in a bufier for a selected
`period of time. e.g.. thirty seconds. Periodically. such as
`every two minutes. the status of all monitored sensors for the
`data elements is written to a file which is stored in the
`vehicle data storage 402. The raw. calculated and derived
`data elements listed above comprise some of the data
`elements to be so stored.
`Certain of the recorded sensor information may comprise
`a trigger event of which inquiry is identified at step 108.
`“Trigger events" are defined as a combination of sensor data
`requiring additional action or which may result in a sur-
`charge or discount during the insurance billing process.
`Certain trigger events may require immediate upload 110 to
`a central control which will then be required to take appro-
`

`priate action. For example. a trigger event would be rapid
`deceleration in combination with airbag deployment indi-
`cating a collision. in which case the system could notify the
`central control of the Vehicle location. Alternatively. if the
`operator were to trigger on an emergency light. similarly the
`system could notify the central control of the vehicle loca-
`tion indicating that an emergency is occurring. The trigger
`information is recorded. as at step 116. and whatever
`response is taken by the central control is also recorded at
`step 118. The trigger information recording step 116 and the
`recording sensor information step 106 may impart recording
`of information in the on-board data storage device 402 or
`memory 406. The event response information recording at
`step 118 will usually occur in the central control station.
`Such response information could be the dispatch of an
`emergency vehicle. or the telephoning of police or an EMS
`unit.
`Trigger events are divided into two groups: those requir-
`ing immediate action and those not requiring immediate
`action. but necessary for proper billing of insurance. Those
`required for proper billing of insurance will be recorded in
`the same file with all the other recorded vehicle sensor
`information. Those trigger events requiring action will be
`uploaded to a central control center which can take action
`depending on the trigger event. Some trigger events will
`require dispatch of emergency services. such as police or
`EMS. and others will require the dispatch of claims repre-
`sentatives from the insurance company.
`The following comprises an exemplary of some. but not
`all. trigger events:
`Need for Assistance:
`These events would require immediate notification of the
`central control center.
`1. Accident Occurrence. An accident could be determined
`through the use of a single sensor. such as the deploy-
`ment of an airbag. It could also be determined through
`the combination of sensors. such as a sudden decelera-
`tion of the vehicle without the application of the brakes.
`. Roadside assistance needed. This could be through the
`pressing of a “panic button” in the vehicle or through
`the reading of a sensor. such as the level of fuel in the
`tank. Another example would be loss of tire pressure.
`signifying a flat tire.
`. Lock-out assistance needed. The reading of a combi-
`nation of sensors would indicate that the doors are
`locked but the keys are in the ignition and the driver has
`exited the vehicle.
`
`4. Driving restrictions. The insured can identify circum-
`stances in which he/she wants to be notified of driving
`within restricted areas. and warned when he/she is
`entering a dangerous area. This could be applied to
`youthful drivers where the parent wants to restrict time
`or place of driving. and have a record thereof.
`Unsafe Operation of the Vehicle
`These events would be recorded in the in-vehicle recording
`device for future upload. Constant trigger events would
`result in notification of the driver of the exceptions.
`1. Excessive speed. The reading of the vehicle speed
`sensors would indicate the vehicle is exceeding the
`speed limit. Time would also be measured to determine
`if the behavior is prolonged.
`. Presence of alcohol. Using an air content analyzer or
`breath analyzer. the level of alcohol and its use by the
`driver could be determined.
`. Non—use of seatbelt. Percent of sample of this sensor
`could result
`in additional discount for high use or
`surcharge for low or no use.
