1. A vehicle height adjusting apparatus for a vehicle, comprising:
- sensor means for detecting a vehicle height level by measuring the distance between the body and axles of said vehicle and for providing an output signal corresponding to said measured height level;
a signal comparator circuit for receiving and comparing said output signal from said sensor means and for classifying said output signal into one of a plurality of vehicle reference height zones;
a pulse converter circuit for converting said classified signal into a pulse signal corresponding to one of said height zones;
an integrator circuit for integrating said pulse signal for each respective zone during a given time period;
a determination circuit for receiving said integrating signal for each zone from said integrator circuit and for comparating the number of pulses for each zone and provide an output signal indicative of said vehicle height level;
and a fluid circuit for controlling the inflow and outflow of fluid into and out of a suspension device in dependance upon said output signal from said determination circuit, whereby said vehicle height level is adjusted to be in a predetermined vehicle reference height zone.

Abstract
A vehicle height adjusting apparatus in which a sensor means detects the distance between the body and axles of a vehicle while the vehicle is parked or moving. A signal comparator divides the vehicle height detection range into a plurality of detection zones based on the sensor signals; a pulse converter circuit converts the signals into pulse signals of the detection zones; an integrator circuit integrates the pulse signals for a period of time; a determination circuit determines the vehicle height level and a fluid circuit controls the inflow and outflow of fluid into and out of a suspension device.
