HYDRAULIC PRESSURE CONTROL DEVICE AND BRAKE HYDRAULIC PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3778811
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent hunting by making a feed current to a linear valve which is switched from the closed state to the opened state in the case where a current being larger than an operation starting current is fed thereto to an appropriate amount.
SOLUTION: A hunting level is defined as a larger value as the number of times of determinations, in which an interval switched from the closed state to the opened state of a boosting linear valve and a reduction linear valve is short, is larger. In the case where the hunting level is high, a hunting tendency is high than that of the case where it is low and a possibility that the hunting is generated is high. Therefore, in the case where the hunting level is high, if a current fed at the time of opening of the valve is made small, a timing switched from the closed state to the opened state can be delayed to inhibit the hunting.
