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 J1708, J1939, OBD, OBDII, OBDIII or CAN vehicle bus using a device communicating with the bus;
b. obtaining an engine RPM from said vehicle bus with said device;
c. developing and using one or more equations where the equations incorporate vehicle speed and engine RPM wherein said equation(s) resolve the value of a vehicle speed using an engine RPM;
d. using said equations with said device to calculate a new resolved vehicle speed and its derivative(s);
e. providing functionality to make the resolved value of the vehicle speed and/or its derivative(s) operationally available through said device.

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.

2. 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. using a device operably connected to a J1708, J1939, OBD, OBDII, OBDIII or CAN vehicle bus to obtain one or more reading(s) of a parameter from said vehicle bus; b. using said device to obtain one or more reading(s) of other parameter(s) from the said vehicle bus; c. developing and using one or more equations which incorporate said parameters wherein said equation(s) resolve the value of the first parameter using the other parameter(s) obtained; d. using said equations with said device to calculate a resolved value for the first parameter and/or its derivative(s); e. providing functionality to make the resolved value of the first parameter and/or its derivative(s) operationally available through said device. - View Dependent Claims (10, 22)
