Abstract:
Tire sensor system, comprising:at least two pick-ups for measuring data from a rotating tire, a motor vehicle control system, wherein said measured data includes at least one analog signal and at least one digital signal, a conditioning and processing unit coupled between the motor vehicle control system and the pick-ups for conditioning and processing the measured data, wherein at least one of the signals contains tire related data in its phase and at least one of the signals contains tire related data in its amplitude, and wherein the conditioning and processing unit couples output information to said motor vehicle control system and calibrates the systematic errors of the output information with respect to whether an error in the measured data is an amplitude-related error or a phase-related error, wherein the amplitude-related error is compensated by a multiplicative calibration and the phase-related error is compensated by an additive calibration in the conditioning and processing unit.
