Vehicle brake fluid pressure control device

A vehicle brake fluid pressure control device, comprising:

• a solenoid valve for generating a pressure differential between upstream and downstream sides thereof in accordance with the magnitude of a control current;
• a control unit for controlling the magnitude of the control current applied to the solenoid valve to generate a target pressure differential between the upstream and downstream sides of the solenoid valve;
• and
• a mark unit for indicating a similarity group of the pressure differential-current characteristics of the solenoid valve, wherein
• the control unit stores a map in which the entire range of variation in pressure differential-current characteristics of the solenoid valve is divided into a plurality of regions respectively defined as the similarity group of the pressure differential-current characteristics, and the control unit identifies the similarity group of the pressure differential-current characteristics of the solenoid valve indicated by the mark unit to identify which of the plurality of regions the solenoid valve is within, and
• when the control unit has identified which one of the plurality of regions the solenoid valve is within, the control unit sets the magnitude of the control current to a value that accords with the identified region when brake fluid pressure control is performed.
