Embodiment Construction

[0063] refer to Figure 1 to Figure 6 , an exemplary embodiment of the system for evaluating tire pressure of the present invention is indicated with "10". like figure 1 As shown, the system 10 evaluates the pressure of each tire 12 supporting the vehicle 14 . It will be appreciated that the vehicle 14 may be any vehicle type and is shown as a commercial vehicle by way of example. Additionally, the vehicle 14 may include any number of tires 12, and the system 10 may assess the pressure in any number of tires on the vehicle.

[0064] The tires 12 are of conventional construction, and each tire is mounted on a corresponding wheel 16 as known to those skilled in the art. Each tire 12 includes a pair of sidewalls 18 that extend to a circumferential tread 20 . As each tire 12 rolls on the ground 24, a footprint 22 is created, which is the contact area of ​​the tread 20 with the ground.

[0065] Additional reference figure 2 and image 3 , the system 10 includes a drive-thro...

Abstract

A system evaluates pressure of at least two tires supporting a vehicle. The system includes a pass-through reader that includes an array of sensors. A first pressure indication for the first tire is determined by the pass-through reader, and a second pressure indication for the second tire is determined by the pass-through reader. A maximum difference threshold is provided and a pressure difference is determined by comparing the first pressure indication to the second pressure indication. A notification is generated by the pass-through reader when the pressure difference exceeds a maximum difference threshold.

Description

technical field [0001] The present invention generally relates to tire monitoring. More particularly, the present invention relates to systems and methods for monitoring air pressure inside vehicle tires as the vehicle drives past a reader or station. In particular, the present invention relates to a drive-by reader system that uses the pressure difference between tires to provide an assessment of tire pressure. Background technique [0002] A number of pneumatic tires support the vehicle and are designed to be used for relatively long periods of time. However, even long-lived pneumatic tires suffer from loss of air pressure due to punctures by nails and other sharp objects, temperature changes, and / or air diffusion through the tire itself. [0003] Pneumatic tires can repeatedly become underinflated as air diffusion reduces tire pressure over time. Accordingly, the vehicle operator or fleet operator must then take repeated actions to maintain the recommended air pressure...
