Title:
BRAKE FLUID PRESSURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2020044952
Kind Code:
A
Abstract:
To obtain a brake fluid pressure control device for a vehicle capable of suppressing an increase in manufacturing cost when configured to detect a rotation angle of a rotor.SOLUTION: A brake fluid pressure control device for a vehicle includes: a base body in which a flow passage of brake fluid is formed; a motor assembly which has a rotor and a stator and drives a pump device provided in the flow passage; a control substrate of a control device which controls the motor assembly; and a housing which stores the control substrate. The brake fluid pressure control device further includes: a permanent magnet which is mounted in the motor assembly and rotates together with the rotor; and a detection sensor which detects a magnetic field generated by the permanent magnet. The motor assembly is arranged in a space surrounded by the base body and the housing. The control substrate is arranged oppositely to the permanent magnet in a rotary shaft direction of the rotor. The detection sensor is mounted in the control substrate.SELECTED DRAWING: Figure 3
