Abstract

The present invention is for a method of creating new vehicle data using existing vehicle data. The method relies on using vehicle parameter(s) to adjust a less accurate parameter or create a new related parameter for subsequent use. This will be useful in situations where the vehicle network signal provided to a device such as an OBDII data collection system is not accurate or does not have enough resolution.

Claims

1. A method of accurately calculating one or more new vehicle parameters using a vehicle parameter obtained from a vehicle bus for vehicle and driving evaluation comprising:

a. Obtaining vehicle speed from a vehicle bus using a device communicating with the bus.

b. Obtaining engine RPM from a vehicle bus with said device.

c. Developing/Using one or more equations where the equations incorporate vehicle speed and engine RPM.

d. Using said equations with said device to calculate a new vehicle speed and/or subsequent parameters and/or other new parameters with finer resolution than their original resolution.

3. The method of claim 1 where the new speed or resulting calculation is used to determine distance.

4. The method of claim 1 where the new speed or resulting calculation is used to determine tire pressure or tire wear.

5. The method of claim 1 where the new speed or resulting calculation is used to determine transmissions and gears parameters.

6. The method of claim 1 where the new speed or resulting calculation is used to determine acceleration/deceleration.

7. The method of claim 1 where the new speed or resulting calculation is used to determine trips parameter(s).

8. The method of claim 1 where the new speed or resulting calculation is used to determine other vehicle parameters.

9. The method of claim 1 which bypasses the equation between speed and RPM and instead uses part of the resolution of the original speed between points for a new value of speed.

10. The method of claim 1 that uses the RPM or speed equations(s) to calculate a different parameter than the original speed.

11. The method of claim 1 where the equation uses the lowest rpm for a particular speed.

12. The method of claim 1 where the equation uses the highest rpm for a particular speed.

13. The method of claim 1 where the equation uses multiple ranges of RPM for a speed or range of speeds.

14. The method of claim 1 where the equation uses multiple ranges of speed for an RPM or range of RPMs.

15. The method of claim 1 where the equation incorporates additional/different parameters to calculate a new speed value or subsequent calculation with finer resolution.

16. The method of claim 1 that improves any speed parameter'"'"'s resolution to finer than 1 Km/hr.

17. The method of claim 1 that improves any distance parameter'"'"'s resolution to finer than 1 Km.

19. The method of claim 1 where the equation between speed and RPM used to improve speed is developed from driving.

20. The method of claim 1 where the equation used to improve the speed or subsequent calculations is a function defined by the transmission and/or gear box of the vehicle.

23. The method of claim 1 that defines multiple equations at points along the resolution values of speed and RPM.

24. A method of calculating vehicle tire diagnostic information comprising:

a. Obtaining a speed from a vehicle bus using a device communicating with the bus and calculating a new vehicle speed/related parameter using engine RPM or another parameter from the bus to obtain a speed resolution finer than its original.

b. Obtaining another vehicle speed/related parameter from another source.

c. Developing one or more equations incorporating said speeds/parameters to calculate tire diagnostic parameters.

25. The method of claim 24 where the equations are developed using speeds at integer values.

a. Using a device operably connected to a vehicle bus to obtain a plurality of readings of a parameter from said vehicle bus.

b. Using said device to obtain a plurality of readings of other parameters from the vehicle bus with finer resolution than the first parameter.

c. Developing one or more equations which incorporate said parameters.

d. Using said device and said equations to recalculate the first parameter and/or subsequent parameters with finer resolution.

e. Providing a way to make the new parameters available for subsequent use.
