Tire pressure monitoring with auto-scaling pressure resolution
First Claim
1. A method of monitoring and expressing tire pressure data information, comprising the steps of:
- triggering a tire pressure monitoring system wheel unit, the triggering comprising passing a first threshold pressure value for a tire, the first threshold pressure value for a tire being selected to establish a first pressure range and a second pressure range;
monitoring pressure of the tire and transmitting signals indicative of tire pressure and determining whether to notify a user that the tire pressure is outside of the second pressure range;
wherein in the first pressure range the signals are converted according to a first conversion variable and in the second pressure range the signals are converted according to a second conversion variable, wherein the first and second conversion variables are of a type selected from the group consisting of a resolution, a scaling factor, and an offset, wherein the first and second conversion variables are of the same type and wherein at least one of the first and second conversion variables is configured to be suitable for a particular application of a vehicle control unit, wherein the tire pressure monitoring system wheel unit is a single tire pressure monitoring system wheel unit.

Abstract
The present disclosure relates to methods, system and devices for monitoring tire pressure data of vehicle wheel units. In an example a method of monitoring and expressing tire pressure data information is provided. The method includes selecting a first threshold pressure value for a tire to establish a first pressure range and a second pressure range. The method also includes monitoring pressure of the tire and generating signals indicative of tire pressure. The method further includes that in the first pressure range the signals are converted to digital signals according to a first conversion variable and in the second pressure range the signals are converted according to a second conversion variable.
