System and method in a centrally - tire inflation for detecting and signaling of an unsuitable change of the tire inflation pressure.

摘要

A method for controlling a CTIS (10) including sensing and reacting to conditions indicative of system faults causing inadequate tire inflation pressurization responses to commanded changes in selected tire inflation pressurization settings, said CTIS of the type having a plurality of operator selectable tire pressurization settings (104-112) which are automatically achieved and maintained by the system, said method characterized by: sensing operator selection of a desired pressure setting to be achieved and maintained by the system; determining the maximum acceptable period for achieving the selected pressure setting from the current pressure setting; beginning the appropriate sequence of inflation/deflation operations to achieve the selected pressure; if the maximum acceptable period expires prior to achieving the selected pressure setting, declaring a system fault and notifying the operator of said fault. A system for carrying out such a method is also disclosed and claimed.
