1. A tire sensor system, comprising:
- a first sensor;
a second sensor spaced apart from the first sensor; and
a processor receiving input signals from the first and second sensors, wherein the processor is programmed to determine a boundary of a contact patch of a tire in response to the input signals when the first sensor is outside the contact patch and the second sensor is over the contact patch.

Abstract
A tire sensor system includes a first sensor and a second sensor spaced apart from the first sensor. The first and second sensors are mounted to a tire. A processor receives input signals from the first and second sensors, and is programmed to determine the length of a contact patch of the tire in response to the input signals.

21. A method for determining boundaries of a tire contact patch, comprising:
-
determining a distance between a first sensor and an inside surface of a tire; determining a distance between a second sensor and the inside surface of the tire; determining a first boundary of the tire contact patch in response to a difference in the distances between the first and second sensors and the inside surface of the tire when the first sensor is outside the contact patch and the second sensor is over the contact patch. - View Dependent Claims (22, 23, 24)

25. A tire system, comprising:
-
a tire; first means for determining a distance between a first location and an inside surface of the tire; second means for determining a distance between a second location and an inside surface of the tire, the second means being spaced apart from the first means; and a processor receiving input signals from the first and second means, wherein the processor is programmed to determine a boundary of a contact patch of the tire in response to the input signals when the first sensor is outside the contact patch and the second sensor is over the contact patch.
