Title:
CORRECTION CONTROL SYSTEM FOR HYDRAULIC PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3927436
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a correction control system for a hydraulic pressure control device which compensates deflection, if any, between an electric signal and output pressure caused by irregularity in a hydraulic pressure circuit.
SOLUTION: This correction control system for a hydraulic pressure control device controls the output pressure based on a current value as an electric signal corresponding to demand output pressure determined by an operation process in a controller. It is provided with an adapted value computing means having basic maps including a plurality of basic maps of different characteristics, and a plurality of semi-basic maps obtained by offsetting the basic maps to compute an adapted value equivalent to difference between an actual output pressure value and a theoretical output pressure value for each of the basic and semi-basic maps, and an optimum map selecting means to select the map to obtain the minimum value among the adapted values computed for the respective maps. A correction item determining means determines a coefficient and a constant for a linear function based on the theoretical output pressure value obtained from the optimum map selected.
