Abstract:
1. A method of monitoring a trailer brake reservoir pressure using a tire management system of a trailer, comprising: providing an existing tire management system on a trailer, the tire management system comprising a trailer tire management electronic control unit having a trailer pressure transducer that is in communication with an air line that is in communication with a trailer brake reservoir; determining an air pressure in the trailer brake air reservoir by sensing air pressure within the air line; providing electronic signals from the trailer tire management electronic control unit that are based on the monitored trailer brake reservoir air pressure, wherein the trailer tire management electronic control unit calculates an air pressure of the trailer brake air reservoir; and communicating the trailer brake air reservoir pressure signals, via the tire management electronic control unit, to a tractor-trailer operator of the trailer; thereby preventing the tractor-trailer operator from moving the trailer, and preventing the trailer tire management system from supplying trailer brake reservoir pressurized air to trailer tires.
