Title:
CHARACTERISTIC ACQUISITION DEVICE OF ELECTROMAGNETIC VALVE AND BRAKE CONTROL DEVICE OF VEHICLE HAVING THE DEVICE
Document Type and Number:
Japanese Patent JP2023046343
Kind Code:
A
Abstract:
To provide a characteristic acquisition device of an electromagnetic valve which can properly acquire a characteristic in consideration of a hysteresis of a solenoid.SOLUTION: A characteristic acquisition device for acquiring operation characteristics Zip, Ziq of a linear-type electromagnetic valve for adjusting pressure Pa of a working fluid discharged by a fluid pump which is driven by an electric motor comprises: "a supply part for supplying a current Ia to the electromagnetic valve"; "an adjustment part for adjusting a rotation number Na of the electric motor"; "a detection part for detecting the pressure Pa"; and "a learning part for storing data Dp, Dq of the pressure Pa to the current Ia, and deciding the operation characteristics Zip. Ziq on the basis of the data Dp Dq". When the supply part keeps the current Ia constant, and the adjustment part changes the rotation number Na and then keeps it constant, the learning part stores the data Dp, Dq.SELECTED DRAWING: Figure 2
