A display apparatus for indicating tire pressure or other information about a vehicle. The display apparatus includes an independent power source, having no connection to the electrical power system of the vehicle, for powering the display apparatus, and a receiver for receiving electromagnetic radiation containing the information from at least one transmitter coupled the vehicle, the information being indicated on a display of the display apparatus.

Remote display system with independent power source

A tire pressure monitoring system identifies tire locations by recognizing that certain characteristics are unique to front-located tires verses rear-located tires as well as left-side tires and right-side tires. A control circuit is coupled to a temperature sensor and an accelerometer for each tire to receive information processed to discriminate between left and right and front and rear tires, respectively. With this information and a pressure signal, the monitoring system provides the operator with tire location and pressure information without reprogramming upon tire rotation. The system also alerts the operator to run-flat tire operational constraints.

Tire monitoring system

A tire pressure monitor is incorporated in a module mounted within a vehicle visor for ready accessibility and visibility by the vehicle operator. The monitor includes a light display extending on a first side of the visor which faces the vehicle operator when the visor is in a raised stored position against the vehicle headliner. A more detailed display is located on the opposite side of the visor for providing an indication to the vehicle operator as to which tire is low in pressure and the pressure of each of the tires.
