Patent Images
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.

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.

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. - View Dependent Claims (25, 26)

27. A method of calculating one or more parameters for use in a device operably connected to a vehicle bus comprising:
-
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. - View Dependent Claims (29, 30)
