Patent Images
1. A method for analyzing the performance of a motor vehicle equipped with an onboard diagnostic system capable of storing data related to the vehicle, monitoring the speed of the vehicle, monitoring the condition of a plurality of sensors, and producing digital signals representative of stored data related to the vehicle, the speed of the vehicle and the condition of said sensors, comprising the steps of:
- a. downloading a set of said digital signals to a computer;
b. using said computer to process said digital signals representative of the process speed of the vehicle to determine a first operating parameter of the vehicle; and
c. displaying said operating parameter.
