Claims (1)

[Scope of utility model registration request] In an electronically controlled suspension device equipped with a front-wheel drive vehicle with a drive shaft of unequal length on the left and right and equipped with a vehicle height adjustment function and a posture control function, a suspension provided for each wheel using a combination of a fluid spring chamber and a coil spring. a control valve that is individually connected to the fluid spring chamber of each suspension unit and controls the supply and discharge of fluid;
an accelerator sensor that detects the open state of the accelerator;
a gear position sensor that detects the shift position of the transmission;
When this gear position sensor detects that the shift position is in a low gear position and the accelerator sensor detects that the accelerator is opened by a predetermined amount or more, the control valves are controlled to open and close to control the vehicle height of the front wheels. What is claimed is: 1. An electronically controlled suspension device characterized by comprising: control means for controlling the suspension;
