Tire inflation and velocity sensor
First Claim
Patent Images
1. A system for determining the pressure a pneumatic vehicular tire while mounted on the wheel of vehicle, and/or velocity of the vehicle comprising:
- a. an array of load sensors which provide a two-dimensional pattern of the force distribution exerted by said tire in contact with said sensors as the vehicle passes over said array;
b. a computer which is programmed (programmed computer) to determine said tire inflation pressure and/or velocity from said force distribution data independent of the make or model of said tire and said vehicle; and
c. means for displaying said pressure (and) and/or velocity.

Abstract
A system that will indicate tire inflation and vehicle velocity. An array of strain gage sensors is used to determine the distribution of contact forces along the width of a pneumatic tire. A neural network may be employed to classify the patterns of force sensed in this manner. Additional processing of the data permits vehicle velocity to also be determined.
