PROBLEM TO BE SOLVED: To provide a vehicle brake fluid pressure control device which reliably suppresses the deviation of a control amount even when a zero point of a master cylinder pressure is deviated upon the start of pressure rising control.SOLUTION: A vehicle brake fluid pressure control device includes: a master cylinder pressure obtaining means which obtains a master cylinder pressure; a brake determining means which determines whether or not a brake lamp switch is turned on; a correction means which corrects the master cylinder pressure so that the master cylinder pressure P2 immediately before the brake lamp switch is turned on (at the time of t1) becomes a zero point when it is determined that the brake lamp switch is turned on; and a pressure rising means that can perform pressure rising control, in which when at least the brake lamp switch is turned on, calculates a control amount based on the master cylinder pressure corrected by the correction means and raises a liquid pressure of a wheel brake based on the control amount. |
