Claims

[Scope of utility model registration request]

At least one air spring is provided between the vehicle body and each axle to support the vehicle body;
An auxiliary air tank connected to each air spring, a solenoid valve that is provided between the air spring and the auxiliary air tank that form a pair, and that changes the spring constant of the air spring by interrupting communication between them; Vehicle height sensors are installed at the front and rear of the vehicle, detect the vehicle height at the front and rear of the vehicle body, and output detection signals respectively. Based on the detection signals from each vehicle height sensor, nose dive or nose up occurs in the vehicle body. an electronic controller that outputs a control signal that switches one of the solenoid valves that are paired with the air springs on the front axle and the solenoid valves that are paired with the air springs on the rear axle to the closed position. An electronically controlled air suspension device for an automobile, characterized by the following:
