Abstract: A vehicle movement tracking system that employs floor mats having ridges for generating location information in the form of modulated vibrations, detectable with an accelerometer. Two sensors are in a wheel of a vehicle. One sensor senses wheel rotation, and the other sensor senses vertical acceleration. The vehicle passes over a floor mat comprising vertically elevated ridges thereon that code the mat and thereby indicate the location at which the mat is at. When the vehicle travels over this mat the vertical acceleration sensor in the wheel detects the vertically elevated ridges and the wheel rotation sensor detects the distance between the vertically elevated ridges. In combination these two sensors are used to create a location word that denotes the mat over which the vehicle passes over. The location word is stored in non-volatile memory and later uploaded to a location collection station.

Abstract: A vehicle movement tracking system that employs floor mats for generating location information using magnetic stripes, detectable with a magnetic sensor in a wheel of the vehicle. Two sensors are in a wheel of a vehicle. One sensor senses wheel rotation, and the other sensor senses a magnetic. The vehicle passes over a floor mat comprising magnetic stripes thereon that code the mat and thereby indicate the location at which the mat is at. When the vehicle travels over this mat, the magnetic sensor in the wheel detects the magnetic stripes and the wheel rotation sensor detects the distance between the magnetic stripes. In combination, these two sensors are used to create a location word that denotes the mat over which the vehicle passes over.
