Claims

[Scope of Claim for Utility Model Registration] A vehicle height sensor that detects the loaded state of a vehicle from the distance between the unsprung and unsprung parts of a suspension spring, and a vehicle height sensor that converts the vehicle height detected by the vehicle height sensor into a loaded weight and the vehicle loaded weight. In the load-responsive hydraulic electronic control system, the load-responsive hydraulic electronic control system is equipped with a control means that calculates an appropriate split pressure for starting rear hydraulic pressure reduction control based on the detected value of the vehicle height sensor, and sets the calculated split pressure to the hydraulic actuator. a non-volatile memory that stores table data or calculation constants for converting the weight into vehicle weight; estimating means for estimating the amount of fatigue of the suspension spring from the relationship between the vehicle loaded weight and time; A load-responsive hydraulic electronic control system comprising: correction means for correcting table data or calculation constants stored in the non-volatile memory when estimating the amount of settling;
