System for tire pressure monitoring for a utility vehicle
First Claim
1. A system for tire pressure monitoring at least one vehicle tire of a utility vehicle, comprising:
- a pressure sensor for detecting an internal tire pressure of the at least one vehicle tire;
an electrically controllable tire inflation system for varying the internal tire pressure; and
a monitoring unit disposed in communication with the pressure sensor and the tire inflation system, wherein the monitoring unit operably identifies a defect-induced loss of pressure in the at least one vehicle tire based on the detected internal tire pressure;
wherein the monitoring unit operably determines a temporal progression of the detected defect-induced loss of pressure;
wherein the monitoring unit operably calculates a volume flow necessary for continuous compensation of the pressure loss based on the temporal progression;
wherein the monitoring unit operably controls the volume flow into the at least one vehicle tire via the tire inflation system;
wherein the monitoring unit determines the temporal progression of the defect-induced loss of pressure after passing through a first escalation stage and a second escalation stage;
wherein the monitoring unit determines that the at least one vehicle tire is defective in response to the progression; and
wherein after passing through the first and second escalation stages of the defect-induced loss of pressure, the continuous compensation of the pressure loss includes an increased volume flow for an accelerated restoration of internal tire pressure followed by a lower volume flow to maintain the internal tire pressure.

Abstract
A system for monitoring tire pressure of at least one vehicle tire of a utility vehicle includes a pressure sensor for detecting an internal tire pressure of the at least one vehicle tire and an electrically controllable tire inflation system for varying the internal tire pressure. The system also includes a monitoring unit disposed in communication with the pressure sensor and the tire inflation system. The monitoring unit identifies a defect-induced loss of pressure in the at least one vehicle tire based on the detected internal tire pressure, determines a temporal progression of the detected defect-induced loss of pressure, calculates a volume flow necessary for continuous compensation of the pressure loss based on the temporal progression, and controls the volume flow into the at least one vehicle tire via the tire inflation system.
