PURPOSE: To stabilize the height of a moving vehicle and quickly adjust the its height at the time of getting in and out, by using the output signals of a vehicle height detector and a movement detector to energize the suspension of the vehicle for a relatively-short prolonged time during the stoppage of the vehicle or for a relatively-long prolonged time during the movement of the vehicle.
CONSTITUTION: Electric power V is applied, an oscillator 211 generates pulses (f) and a counter CO1 sends out pulses of double, eightfold and sixteen-fold periods from terminals Q0WQ3 and another counter CO2 counts the pulses from the terminal Q2. Until the counter CO2 has counted eight pulses, its terminal Q3 is kept at a low level so that a door switch 50 is closed after the application of the electric power V. When a flip-flop FF1 remains reset and the counter CO2 has not yet counted eight pulses before the starting of a vehicle, short-period pulses (h) are supplied to an energizing controller 220. After the counting of the eight pulses and the starting of the vehicle, long-period pulses (g) are supplied to the energizing controller 220. According to this constitution, the height of the vehicle at the time of getting in and out is quickly adjusted and the frequency of the adjustment of the vehicle height is reduced to stabilize the height.
