Abstract

A method and system for determining comparative performance of an alternative fuel vehicle, such as an electric or hybrid vehicle, based on actual use of an existing gasoline or diesel fuel vehicle. The method includes obtaining trip data from an existing vehicle, determining performance metrics of the vehicle based on the trip data, determining simulated performance metrics of an alternative fuel vehicle based on the trip data, comparing the performance metrics of the existing vehicle and the simulated performance metrics of the alternative fuel vehicle, and presenting the comparison to the operator.

Claims

1. A method of determining expected performance of an alternative fuel vehicle based on actual use of an existing vehicle, comprising the steps of:

(a) obtaining trip data from an existing vehicle driven by a vehicle operator;

(b) determining performance metrics of the vehicle based on the trip data;

(c) determining simulated performance metrics of an alternative fuel vehicle based on the trip data;

(d) comparing the performance metrics of the existing vehicle and the simulated performance metrics of the alternative fuel vehicle; and

(e) presenting the comparison to the operator.

2. The method of claim 1, further comprising the step of creating a chained trip by waiting until a predefined period of time has passed after an ignition off event to upload the trip data.

3. The method of claim 1, wherein the performance metrics of the existing vehicle further comprise one or more of:

a trip duration and time of day, a time and day of an ignition on event, a time and day of an ignition off event, the average miles per trip, a number of trips taken in the existing vehicle, or an average number of miles driven per day.

4. The method of claim 1, wherein the simulated performance metrics further comprises the total number of miles travelled that would be electrically-powered if driven in the alternative fuel vehicle or the total number of miles travelled that would be petroleum-powered if driven in the alternative fuel vehicle, or both.

5. The method of claim 1, further comprising the step of saving the performance metrics of the existing vehicle based on a unique vehicle identifier.

6. The method of claim 1, further comprising the step of displaying the comparison to the operator in the form of a graph.

7. The method of claim 1, further comprising the step of sending the comparison to the operator in the form of an SMS message or an email.

8. A method of determining expected performance of an alternative fuel vehicle based on actual use of an existing vehicle, comprising the steps of:

(a) sending an ignition-on time stamp and odometer reading from a plurality of vehicles to a call center;

(b) sending an ignition-off time stamp and odometer reading from the plurality of vehicles to the call center;

(c) determining vehicle trip data based on associated ignition-on and ignition-off time stamps and odometer readings from each of the vehicles;

(d) processing the vehicle trip data for the plurality of vehicles; and

(e) calculating a theoretical range for a alternative fuel vehicle based on the processed data, wherein the theoretical range is based on the battery power of one or more batteries installed on the alternative fuel vehicle.

9. The method of claim 8, further comprising the step of creating a chained trip by waiting until a predefined period of time has passed after the ignition off time stamp to upload the ignition-off time stamp and associated odometer reading.

10. The method of claim 8, wherein the step of processing the trip data further comprises calculating one or more of:

an average trip duration for each day of the week, an average time and day of an ignition on event, an average time and day of an ignition off event, an average miles per trip, an average number of trips taken in a vehicle, or an average number of miles driven per day.

11. The method of claim 8, wherein the step of calculating the theoretical range further comprises calculating the total number of miles travelled that would be electrically-powered if driven in the alternative fuel vehicle, or the total number of miles travelled that would be petroleum-powered if driven in the alternative fuel vehicle, or both.

12. The method of claim 8, wherein step (d) further comprises averaging the vehicle trip data and wherein the method further comprises the step of displaying the averaged vehicle trip data using a graph.

13. A method of determining expected performance of an alternative fuel vehicle based on actual use of an existing vehicle, comprising the steps of:

(a) recording a time stamp and odometer reading for one or more vehicles at ignition-on;

(b) uploading the ignition-on time stamp and the odometer reading for one or more vehicles to a call center following the ignition-on;

(c) recording a time stamp and an odometer reading for the one or more vehicles at ignition-off;

(d) uploading the ignition-off time stamp and the odometer reading for the one or more vehicles to the call center following the ignition-off;

(e) calculating a plurality of trip durations and times of day based on the uploading of the ignition-on time stamp and the uploading of the ignition-off time stamp;

(f) determining an average trip duration at periodic times during a day;

(g) determining the vehicle performance metrics of a particular vehicle based on a vehicle identifier and the ignition-on and ignition-off uploads for the particular vehicle;

(h) creating a hypothetical alternative fuel vehicle profile based on the determined vehicle performance of the particular vehicle; and

(i) graphically displaying the determined average trip durations and times of day, the performance metrics of the particular vehicle, and the hypothetical alternative fuel vehicle profile to a vehicle operator.

14. The method of claim 13, further comprising:

creating a chained trip by waiting until a predefined period of time has passed after an ignition off event to upload the ignition-off time stamp and the odometer reading.

15. The method of claim 13, wherein the vehicle performance metrics of a vehicle further comprises one or more of:

a trip duration and time of day, a time and day of an ignition on event, a time and day of an ignition off event, an average miles per trip, a number of trips taken in a vehicle, or an average number of miles driven per day.

17. The method of claim 13, further comprising the step of saving the performance metrics of the particular vehicle based on a unique vehicle identifier.

18. The method of claim 13, wherein the hypothetical alternative fuel vehicle profile further comprises the total number of miles travelled that would be electrically-powered if driven in the alternative fuel vehicle or the total number of miles travelled that would be petroleum-powered if driven in the alternative fuel vehicle, or both.

19. The method of claim 13, further comprising the step of sending the comparison to the operator in the form of an SMS message or an email.

20. The method of claim 13, further comprising the step of receiving a request from the vehicle operator to begin obtaining vehicle operator driving habits.
