Abstract:
1. A method of determining the location information of a plurality of wheels mounted on a vehicle, each said wheel having a plane of rotation and said vehicle comprising a body having a first and a second lateral side, the method comprising the steps of: attaching an accelerometer to each one of said plurality of wheels of said vehicle, wherein each said accelerometer is adapted to transmit a transverse acceleration signal in response to acceleration in a direction orthogonal to the plane of rotation of a said wheel, the polarity of a said transverse acceleration signal transmitted by a said accelerometer mounted on one said lateral side of said vehicle being opposite to the polarity of another said transverse acceleration signal transmitted by another said accelerometer mounted on another said lateral side of said vehicle upon said vehicle making a lateral turn towards either said first or said second lateral side to change its course of motion; obtaining a relationship between the lateral location of a said wheel and the polarity of said transverse acceleration signal transmitted by a said accelerometer of a said wheel in response to a lateral turn of said vehicle in a direction of a said lateral side of said vehicle; and determining the lateral location of a said wheel with reference to the polarity of said transverse acceleration signal transmitted by said accelerometer of said wheel upon the vehicle undergoing a said lateral turn.
