SYSTEM AND METHOD FOR ODOMETER CALIBRATION
First Claim
1. A system for odometer calibration for a motor vehicle comprising:
- a first source of speed data providing first speed data for the motor vehicle for a duration of operation of the motor vehicle;
a second source of speed data providing second speed data for the motor vehicle for a portion of the duration of operation of the motor vehicle;
a control module that computes an overall average speed based on the first speed data and the duration of operation of the motor vehicle, computes an intermittent average speed based on the first speed data and the portion of the duration of operation of the motor vehicle and computes a second average speed based on the second speed data and the portion of the duration of operation of the motor vehicle; and
wherein based on the overall average speed and a ratio of the second average second speed to the intermittent average speed the control module computes corrected odometer data.

Abstract
A system for odometer calibration for a motor vehicle is provided. The system can include a first source of speed data that provides first speed data during operation of the motor vehicle, and a second source of speed data that provides second speed data during a portion of the operation. The system can also include a vehicle speed control module that computes overall average speed data based on the first speed data and a duration of operation. The system includes a speed control module that determines an average first speed for the portion of the operation in which the second source of speed data provides the second speed, and computes an average second speed. The system can include an odometer correction control module that computes corrected odometer data based on the overall average speed data and a ratio of the average second speed to the average first speed.
