DETERMINING VELOCITY USING MULTIPLE SENSORS
First Claim
1. A method for determining velocity of a vehicle comprising the following computer-executable acts:
- receiving first acceleration data that is indicative of a velocity of the vehicle over a period of time, wherein the first acceleration data corresponds to a first sensor;
receiving second acceleration data that is indicative of a velocity of the vehicle over the period of time, wherein the second acceleration data corresponds to a second sensor;
determining first difference data that is a difference between the first velocity data and the second velocity data;
determining final velocity data that is a velocity of the vehicle based at least in part upon the first difference data; and
outputting the final velocity data.

Abstract
A system described herein includes a receiver component that receives first velocity data that is indicative of a velocity of a vehicle over a period of time, wherein the first velocity data corresponds to a first sensor. The receiver component also receives second velocity data that is indicative of the velocity of the vehicle over the period of time, wherein the second velocity data corresponds to a second sensor. The system also includes a modifier component that determines a difference between the first velocity data and the second velocity data and outputs at least one final velocity value for the vehicle based at least in part upon the first difference data.
