Abstract

An apparatus for remotely collecting and reporting an indicia of use of a vehicle. The apparatus includes an accumulator of the indicia of vehicle use operably coupled to the vehicle and a transceiver coupled to the accumulator and responsive to a received information request for transmitting the indicia of vehicle use.

Claims

1. An apparatus for remotely collecting and periodically reporting an indica of use of a vehicle to a central station through a cellular communication network, such apparatus comprising:

a safety inspection button which may be activated by an operator of the vihicle indicting that the operator has inspected the vehicle for safety defects and certified to an operability of the vehicle;

a vehicle use sensor coupled to the safety inspection button and to a power unit of the vehicle which detects an indicia of use of the power unit;

an indicia of vehicle use register operably coupled to the vehicle use sensor of the vehicle which contains a file of accumulated vehicle use including safety inspections for periodically transmission to the central station; and

a wireless cellular transceiver of the cellular network coupled to the register and having a cellular identifier, said cellular transceiver being disposed to selectively activate for transmitting indicia of vehicle use to the central station only in response to a periodically received information request coded with the cellular identifier of the cellular transceiver.

2. The apparatus as in claim 1 further comprising a controller coupled to the cellular transceiver and register for decoding the received information request for a communication target identifier and for transmitting the current indicia of vehicle use upon finding a match between the received communication target identifier and an internal vehicle identifier.

3. The apparatus as in claim 2 further comprising a memory for storing the cellular identifier.

4. The apparatus as in claim 1 wherein the cellular transceiver further comprises a packet data transceiver.

5. The apparatus as in claim 1 wherein the indicia of vehicle use register further comprises a timer coupled to a vehicle activation switch.

6. The apparatus as in claim 1 wherein the indicia of vehicle use further comprises a counter coupled to mileage indicator.

7. The apparatus as in claim 1 further comprises a global positioning system coupled to and providing geographical position as an indicia of vehicle use for transmission to the central station.

8. The apparatus as in claim 1 wherein the indicia of vehicle use further comprises an output of a crankcase oil level sensor.

9. The apparatus as in claim 1 wherein the indicia of vehicle use further comprises an output of a transmission fluid level sensor.

10. The apparatus as in claim 1 wherein the indicia of vehicle use further comprises an output of a radiator fluid level sensor.

11. The apparatus as in claim 1 wherein the indicia of use further comprises an output of a battery charge level sensor.

12. The apparatus as in claim 1 wherein the indicia of use further comprises a vehicle engine revolutions per minute indication.

13. The apparatus as in claim 1 wherein the indicia of use further comprises a vehicle braking rate.

14. The apparatus as in claim 1 wherein the indicia of use further comprises a vehicle safety check complete indicator.

15. A system for collecting an indicia of vehicle use from a plurality of remotely located vehicles through a cellular communications network comprising:

a central computer which periodically transmits an information request to a vehicle of the plurality of remotely located vehicles through the cellular network using a cellular identifier;

a cellular transceiver having a cellular identifier, said cellular transceiver disposed on the vehicle; and

,

a vehicle information collection unit coupled to a power unit of the vehicle and to the cellular transceiver;

a safety inspection button coupled to the vehicle information collection unit which may be activated by an operator of the vehicle indicating that the operator has inspected the vehicle for safety defects and certified to an operability of the vehicle and wherein the vehicle information collection unit responds to the information request though the cellular transceiver with indicia of accumulated vehicle use including safety inspections only when the cellular identifier of the information request matches the cellular identifier of the cellular transceiver.

16. The system as in claim 15 wherein the vehicle collection unit and cellular transceiver further comprises a unitary assembly.

17. The system as in claim 15 wherein the vehicle collection unit further comprises an indicia of vehicle use register.

18. The system as in claim 17 wherein the indicia of vehicle use register further comprises a timer controlled by vehicle use.

19. The system as in claim 17 wherein the indicia of vehicle use register further comprises a counter activated by the vehicle mileage indicator.

20. The system as in claim 17 wherein the vehicle information collection unit further comprises a global position sensor.

21. The system as in claim 17 wherein the indicia of vehicle use register further comprises a global position sensor register.

22. The system as in claim 17 wherein the cellular transceiver further comprises a packet data transceiver.

23. A system for collecting maintenance information from a plurality of remotely located mobile vehicles through a wireless cellular communication network, such system comprising:

a central station which periodically polls each mobile vehicle of the plurality of remotely located mobile vehicles through the wireless cellular network by transmitting a plurality of information requests each containing a cellular identifier of a particular mobile vehicle;

a data collection unit disposed on each mobile vehicle of the plurality of mobile vehicles further comprising;

a vehicle use sensor coupled to a power unit of the vehicle which may be activated by an operator of the vehicle indicating that the operator has inspected the vehicle for safety defects and certified to an operability of the vehicle;

an indicia of vehicle use register operably coupled to the vehicle use sensor of the mobile vehicle and which contains a file of accumulated indicia of vehicle use;

a cellular transceiver operably coupled to the vehicle use register and having an internal cellular identifier, such cellular transceiver configured to selectively activate and transmit indicia of vehicle use to the central station in a transmission including a cellular identifier of the central station only upon detection of an information request received through the cellular network from the central station and encoded with the cellular identifier of the cellular transceiver.

24. The system for collecting maintenance information from a plurality of mobile vehicles as in claim 23 wherein the cellular transceiver further comprises a scanner for scanning cellular channels for information requests.
