Self training tire pressure monitoring system

A method for determining a pressure and location of each of at least two tires of a vehicle, the at least two tires being mounted at respective ones of at least two wheels of the vehicle, said method comprising:

• sensing a measured pressure within at least two tires of a vehicle in response to pressure sensors at respective tires of the at least two tires;
• deducing a deduced characteristic signature at respective wheels of at least two wheels of the vehicle, said deduced characteristic signature being indicative of pressure variations in the tires mounted at the respective wheels of the vehicle;
• correlating said measured pressures with said deduced characteristic signatures to determine the particular wheel at which each of the at least two tires is mounted;
• and
• displaying the measured pressure of the tire at the particular wheel of the vehicle.

A self training tire pressure monitoring system for a vehicle having a set of tires, the tires being mounted at respective ones of a set of wheels of the vehicle, said self training tire pressure monitoring system comprising:

• at least two pressure sensors, said at least two pressure sensors being positioned at respective tires of a set of tires of the vehicle, said at least two pressure sensors being operable to provide a measured pressure output indicative of the actual pressure of the respective tires;
• at least two wheel sensors, said at least two wheel sensors being positioned at respective wheels of the vehicle, said at least two wheel sensors being operable to provide a wheel rotation output indicative of rotation of the respective wheels;
• a control receiving said measured pressure outputs and said wheel rotation outputs, said control being operable to deduce a deduced rolling radius for the tire mounted at a particular wheel in response to said wheel rotation output indicative of rotation of the particular wheel, said control being operable to integrate said measured pressure outputs and said deduced rolling radii to determine the particular wheels at which said at least two pressure sensors and associated tires are positioned;
• and
• a display operable to indicate the measured pressure of the tire at a particular wheel of the vehicle.
