Abstract

A circuit for the detection of vehicle attitude, comprising a signal sensor, which is arranged inside the cylinder of a shock absorber and coaxial with the piston thereof. The sensor cooperates with a processor for receiving and processing the sensor signals. The sensor includes a first coil electrically connected to a second coil. The free ends of the coils are electrically connected to capacitive circuit means so as to form a variable-frequency resonant circuit fed by an AC power supply through suitable terminals. The circuit is connected to the inputs of parallel processors which convert the frequencies of the variable signal controlled by the sensor and of the fixed signal provided by the power supply to variable-voltage signals, respectively. Both converted signals are applied to a comparator circuit at the output terminals of which any voltage change is measured so as to detect any relative position change of the piston with respect to the cylinder.
