Abstract

A method and apparatus that allows for monitoring the operation and usage of a vehicle. A data logger is installed in a vehicle to be monitored. The data logger couples to the vehicle'"'"'s electronic system and monitors data relating to usage and condition of the vehicle. In one embodiment, the data logger includes a position determining system for determining whether the vehicle has traveled outside of a predetermined area and accelerometers for determining whether the vehicle has been involved in a collision. The data logger transmits information relating to the condition and usage of a vehicle each time that a vehicle return to a facility. The information relating to the condition and usage of the vehicle is then coupled to a computer. This allows for easily monitoring the usage and condition of vehicles without requiring manual data entry.

Claims

1. A method for monitoring a vehicle that includes an electronic system that includes sensors, said method comprising the steps of:

a.) providing a data logger, said data logger disposed within said vehicle and coupled to said electronic system;

b.) receiving a first signal at said data logger, said first signal indicating the rental of said vehicle;

c.) monitoring the usage of said vehicle after the receipt of said first signal, data relating to the usage of said vehicle stored in said data logger;

d.) receiving a second signal at said data logger, said second signal indicating the return of said vehicle; and

e.) transmitting said data relating to the usage of said vehicle.

2. The method for monitoring a vehicle of claim 1 wherein said step of monitoring the usage of said vehicle further comprises:

c1.) determining the distance traveled by said vehicle since the receipt of said first signal; and

c2.) determining if a collision has occurred.

3. The method for monitoring a vehicle of claim 1 wherein said data logger includes a position determining system, said step of monitoring the usage of said vehicle further comprising:

c3.) determining if said vehicle has traveled outside of a designated area.

4. The method for monitoring a vehicle of claim 1 further comprising the steps of:

f.) determining the condition of said vehicle when said second signal is received; and

g.) transmitting the condition of said vehicle.

5. The method for monitoring a vehicle of claim 4 wherein step f.) includes the steps of:

f1.) determining the amount of fuel in said vehicle; and

f2.) determining whether said vehicle requires service.

6. A method for monitoring a vehicle having an electronic system that is rented from a car rental facility comprising:

a.) providing at least one transmitter at each of a plurality of car rental facilities;

b.) providing a first communication unit at each of a plurality of car rental facilities;

c.) providing a computer at each of said plurality of car rental facilities, said computer coupled to said first communication unit;

d.) transmitting a first signal from said at least one transmitter, said first signal indicating the rental of a vehicle;

e.) providing a data logger disposed within a vehicle to be rented, said data logger adapted to receive said first signal;

f.) transmitting a second signal from said at least one transmitter indicating the return of said vehicle;

g.) monitoring data relating to the usage of said vehicle at said data logger from the time that said first signal is received at said data logger until the time that said second signal is received at said data logger;

h.) transmitting said data relating to the usage of said vehicle from said data logger; and

i.) receiving said data relating to the usage of said vehicle at said first communication unit, said first communication unit coupling said data relating to the condition and usage of said vehicle to said computer.

7. The method for monitoring a vehicle of claim 6 further comprising the step of:

j1.) determining the amount to charge for the rental of said vehicle based on the data relating to the usage of said vehicle.

8. The method for monitoring a vehicle of claim 6 wherein said step of monitoring data relating to the usage of said vehicle further comprises:

g1.) determining the distance traveled by said vehicle since the receipt of said first radio signal; and

g2.) determining if a collision has occurred.

9. The method for monitoring a vehicle of claim 8 wherein said data logger includes a position determining system and wherein step g.) further comprises monitoring whether said vehicle has traveled outside of a designated area.

10. The method for monitoring a vehicle of claim 6 further comprising the steps of:

j.) determining the condition of said vehicle when said second radio signal is received; and

k.) transmitting the condition of said vehicle from said data logger when said second radio signal is received.

11. The method for monitoring a vehicle of claim 10 wherein said step j.) further includes the steps of:

j1.) determining the amount of fuel in said vehicle; and

j2.) determining whether said vehicle requires service.

12. The method for monitoring a vehicle of claim 6 wherein said at least one transmitter is a radio transmitter.

13. The method for monitoring a vehicle of claim 6 wherein said first communication unit is adapted to communicate using infrared methods.
