Claims

[Scope of utility model registration request]

a vehicle height sensor that detects the distance between the vehicle body and the axle; a vehicle height adjuster that increases or decreases the distance between the vehicle body and the axle; a compressor that supplies air to the vehicle height adjuster; and the vehicle body adjuster. A vehicle height control system comprising: a valve provided in a conduit connecting the compressor; and a control circuit that controls the compressor and the valve based on the output of the vehicle height sensor. first and second logic circuits that perform certain logic operations on inputs to the control circuit; and when the corresponding outputs of the first logic circuit and the second logic circuit match, the first logic circuit A vehicle height adjustment device comprising: a matching circuit that allows an output to pass through and prohibits the output of the first logic circuit when the corresponding outputs do not match.
