Abstract
Techniques for determining, by external means, the internal pressure of a pneumatic tire. From fundamental relationships, pressure in a tire can be measured as a function of the weight on the wheel divided by area of the tire on the ground. Area and weight sensors can be configured into a low profile package or mat. As a vehicle is driven across the mat, the sensors extract weight and area information from each tire. Then a computational device calculates the tire pressure in each of the four tires of the vehicle and presents this information to the driver visually or aurally. Operation of the device is transparent to the driver, requiring him or her only to drive over or stop on the designated area containing the sensors.
