液圧制御装置
Document Type and Number:
Japanese Patent JP7234715
Kind Code:
B2
Abstract:
To provide a liquid pressure braking device capable of achieving both of redundancy and fine control.SOLUTION: The present invention includes: a linear solenoid valve 51 having a valve body 91 drivable by action of electromagnetic force, a first coil 93 which is formed of a conduction wire separate from the first coil 93 and generates electromagnetic force that acts on the valve body 91 upon electric conduction and a second coil 94 for generating electromagnetic force that acts on the valve body 91 by electric conduction; and a control unit 61 for controlling an action of a linear solenoid valve 51 by controlling at least one of a first control electric current being an electric current flowing to the first coil 93 and a second control electric current being an electric current of flowing to the second coil 94. The control unit 61 gradually changes the first control electric current to one of an increasing side and a decreasing side without changing the second control electric current when actuating the linear solenoid valve 51, and executes specific control for changing the second control electric current to the one side after the first control electric current becomes a prescribed value.SELECTED DRAWING: Figure 1
