Automobile mileage notification system

## Abstract

The application describes a system for notifying a vehicle owner regarding service due for a vehicle based on the vehicle's accumulated mileage. The system determines vehicle mileage based on GPS data, determines whether the mileage has exceeded a threshold, transmits a wireless signal from the vehicle to a notification service provider computer when the threshold is exceeded, and sends a notice from the notification service provider to the dealer and/or customer to indicate that vehicle service is due.

## Background
This nonprovisional application claims priority to U.S. provisional patent application No. 60/954,617 filed Aug. 8, 2007.


FIELD
This invention relates to the field of wireless communication systems. More particularly, this invention relates to a system for transmitting a signal to notify an automobile dealer or owner when the vehicle has met or exceeded a certain mileage threshold and for providing notification that service is due.
BACKGROUND AND SUMMARY
Automobile dealers spend about $250 per vehicle in direct mailings to car owners who have purchased a new vehicle to remind the owners of the need for service that should be performed at certain mileage intervals. In many cases, due to the inability to obtain accurate odometer readings or accurately predict when a vehicle has reached or is about to reach various mileage thresholds, the notices sent to the owners will either be too early or too late.
What is needed, therefore, is a system for automatically determining a vehicle's mileage and providing notifications to the vehicle owner that service is due when the vehicle has exceeded various mileage thresholds, such as by way of an email, text message, or right-time advertisement.
The present invention determines vehicle mileage based on accumulated GPS data, determines whether the mileage has met or exceeded a predetermined threshold stored in a vehicle-mounted device, transmits a wireless signal from the vehicle to a central data hub when the threshold is exceeded, and sends a notice from the central data hub to the dealer and/or vehicle owner to indicate that service is due.

DETAILED DESCRIPTION
Shown in FIGS. 1 and 2 are an apparatus and method for providing a notification regarding service due for a vehicle based on the vehicle's mileage. An in-vehicle mileage recording/transmission unit 10 includes a global positioning system (GPS) device 12, a processor or controller 14, a memory device 16 and a wireless transceiver 18. The GPS device 12 continuously records location data, date/time and accumulated distance traveled, such as in one-second intervals (step 100 in FIG. 2). This data is stored in an event file in the memory device 16 (step 102). Also stored in the memory device 16 is a programmable benchmark or variable threshold values for automated notification parameters.
In a preferred embodiment of the invention, the components of the in-vehicle mileage recording/transmission unit 10 are contained in a single housing that may be installed in an out-of-sight location within the dashboard or under the hood of the vehicle.
As discussed in more detail below, the threshold values may be reprogrammed remotely using signals transmitted to the in-vehicle mileage recording/transmission unit 10. These parameters include a distance-traveled parameter, also referred to herein as vehicle mileage. The distance-traveled data is recorded as an absolute value, including any and all distances traveled by the vehicle in either the forward or reverse directions.
Once the stored distance-traveled value equals or just exceeds the mileage threshold value (step 104), the processor 14 activates the wireless transceiver 18 to initiate a wireless data session with a wireless network 20 (step 106). For example, the wireless transceiver 18 may be a transceiver operating according to the Global System for Mobile (GSM) communication protocol or other cellular telephone protocol. The wireless transceiver 18 transmits a notification signal via the wireless network 20 to a notification service provider computer system 30, such as a system operated by PROCON, Inc. in Orange County, Calif. The notification signal includes vehicle-specific identification information that uniquely identifies the vehicle in which the unit 10 is installed or the unit 10 from which the signal was transmitted. The notification signal also preferably includes a parameter indicating the mileage threshold that has been exceeded (such as 5,000 miles or 30,000 miles).
Once the notification signal has been successfully transmitted, the next threshold value may be set (step 108) and the mileage counter can be reset to zero (step 110). In one embodiment of the invention, these steps are performed automatically based on firmware instructions executed by the processor 14 of the in-vehicle unit 10. In another embodiment, these steps are initiated based on a transmission from the notification service provider 30 to the in-vehicle unit 10 via the wireless network 20.
Upon receipt of the notification signal, the notification service provider computer 30 cross-references the identification information against data in the database 22 that identifies the owner of the vehicle and/or the automobile dealer who sold the vehicle to the owner and/or a third-party vehicle service company that has acquired rights to receive the notification information (step 112). The notification service provider 30 then sends information to the owner (step 114), to the dealer (step 116), or to both indicating that the vehicle's mileage has reached (or is about to reach) a certain value, such as 5000 miles, at which a first vehicle service should be performed. This notification information is preferably sent in an electronic format via the Internet or a wireless data communication network to the dealer computer 26 or to the vehicle owner computer 28. If this information is sent to the dealer computer 26, the dealer may then wish to send the owner a mailing or other communication inviting the owner to make an appointment to service the vehicle (step 118).
In some preferred embodiments, the in-vehicle mileage recording/transmission unit 10 periodically transmits the accumulated vehicle mileage value to the notification service provider computer 30 via the wireless transceiver 18 and the wireless network 20. This transmission also includes the vehicle identification information. The notification service provider computer 30 then accesses the appropriate records in the database 22 for the identified vehicle and compares the accumulated mileage value to a mileage threshold value stored in the database 22 for the particular vehicle. If the accumulated mileage value exceeds the stored threshold value, the notification service provider 30 sends information to the owner, to the dealer, or to both indicating that the vehicle's mileage has reached a certain value indicating that vehicle service is due. In this embodiment, the mileage thresholds are maintained in the database 22 of the notification service provider computer 22 rather than in the memory 16 of the in-vehicle unit 10. This reduces the memory requirements of the in-vehicle unit 10 and eliminates any need to transmit signals from the notification service provider 30 to the in-vehicle unit 10 to reset accumulated mileage values or threshold values.
In some embodiments, the in-vehicle unit 10 includes an On-Board Diagnostics (OBD) connector 32 as shown in FIG. 1. This connector 32 is operable to connect to a mating OBD connector in the vehicle. Through this OBD connection, the processor 14 of the in-vehicle unit 10 can access the Vehicle Identification Number (VIN) of the vehicle, and the VIN may be transmitted from the unit 10 to the notification service provider 30 along with the mileage notification signal. In this embodiment, VINs of vehicles are maintained in the database 22 of the notification service provider 30 rather than, or in addition to, the serial numbers of the in-vehicle units. In this way, any in-vehicle unit 10 may be used in any vehicle, and the notification service provider 30 need only maintain the VINs in its records.
In some embodiments of the invention, the entity acting as the notification service provider also provides the complete end-to-end service for the vehicle owner. This service would include coordinating with the automobile dealer service departments, sending notifications directly to the vehicle owners on behalf of the dealer service departments, and actually setting the appointments.
The communication from the notification service provider to the owner or dealer may be in the form of an email message, SMS text message, telephone message, postcard mailing or other form of communication.
This system may also be used to provide notification of service due at other mileage intervals, such as 30,000 miles and 60,000 miles.
The foregoing description of preferred embodiments for this invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings. The embodiments are chosen and described in an effort to provide the best illustrations of the principles of the invention and its practical application, and to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally, and equitably entitled.
