。 At least one air spring is provided between the vehicle body and each axle to support the vehicle body;
A first valve means provided between an auxiliary air tank connected to each air spring, and the air spring and auxiliary tank that are paired with each other, and for changing the spring constant of the air spring by cutting off communication between them. an air supply source that supplies air to each auxiliary air tank; second valve means provided between the air supply source and each auxiliary air tank; and a second valve means that detects the air pressure in each auxiliary air tank or air spring. A pressure sensor outputs a pressure signal based on the pressure signal, a sensor means detects various motion postures of the vehicle body and outputs the respective detection signal, and the air pressure of the auxiliary air tank or air spring is adjusted based on the pressure signal from the pressure sensor. If the level is below a predetermined level, the air in each air spring and its corresponding auxiliary air tank is released by opening the first and second valve means and filling each auxiliary air tank with air from the air supply source. on the basis of these detection signals, the detection signals from the sensor means are valid only when the air pressure in each auxiliary air tank or air spring is at a predetermined level. 1. An electronically controlled air suspension device for an automobile, comprising: an electronic controller that outputs a control signal for opening and closing a valve means to control a spring constant of each air spring.
