Abstract: A control circuit for a vehicle level adjusting apparatus which avoids performing vehicle level adjustment in response to momentary changes in the vehicle level during driving of the vehicle, and at the same time provides a prompt vehicle level adjustment in response to essential or substantial changes in the vehicle level during a halt or rest state. The control circuit includes a first circuit which receives at least one first signal based on a comparison between a reference vehicle level range and an actual vehicle level to make a judgment as to the necessity of an adjustment of the vehicle level and issues a second signal having a first signal status when the adjustment is judged to be necessary and a second signal status when the adjustment is judged to be unnecessary.
