Claims (1)

[Scope of utility model registration request] A hydraulic suspension control device equipped with a vehicle height adjustment mechanism that adjusts the vehicle height by outputting a vehicle height correction signal to match the actual vehicle height target vehicle height,
The lateral acceleration acting on the vehicle is detected by the lateral acceleration detection means, and the vehicle height correction output calculation means calculates the vehicle height correction output based on the vehicle height adjustment output obtained by multiplying the vehicle height correction signal by the vehicle height adjustment gain. A control device for a hydraulic suspension, wherein the vehicle height adjustment gain setting means for outputting the vehicle height adjustment gain decreases the vehicle height adjustment gain in accordance with an increase in the absolute value of the lateral acceleration.
