Patent ID: 7699409

Claim:
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 to which the solenoid belongs, among a plurality of predetermined similarity groups, wherein the predetermined similarity groups are grouped according to similarity of pressure differential and current characteristics, the control unit stores a map in which the entire range of variation in pressure differential and current characteristics of the solenoid valve is divided into a plurality of regions according to similarity, and the predetermined similarity groups respectively correspond to the regions, and the mark unit signals to the control unit the similarity group to which the solenoid valve belongs, and when the control unit has identified which one of the plurality of regions the solenoid valve is within, according to the similarity group signaled by the mark unit, 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.
