Abstract
A brake fluid pressure control apparatus for a vehicle includes a parameter calculation unit configured to calculate a rollover detection parameter; and a steering maneuver determination unit configured to determine whether an abrupt steering maneuver is made. The parameter calculation unit is configured to calculate a first composition roll angle as the rollover detection parameter, by combining at a predetermined weight assignment ratio a first roll angle equivalent to an actual roll angle with a second roll angle obtained using a parameter which changes with a phase earlier than the first roll angle, and to calculate the first composition roll angle by changing the weight assignment ratio such that a weight of the second roll angle is higher when the steering maneuver determination unit determines that an abrupt steering maneuver is made than when the steering maneuver determination unit determines that the abrupt steering maneuver is not made.
