PROBLEM TO BE SOLVED: To provide a brake booster control device provided with a liquid pressure feeding source capable of pressurizing a brake liquid fed from a master cylinder and feeding it to a wheel cylinder, and capable of preventing the generation of a variation of brake liquid pressure irrelevant to the intention of a driver when wheel cylinder pressure is boosted and controlled according to a brake operation state amount. SOLUTION: A plurality of wheel cylinder pressure setting values (target arrival pressure Pwc(n)) are set, and a range of a plurality of brake operation state amounts (mater cylinder pressure Pmc) having inherent upper-limit values (threshold Pu(N+1)=Pd(n+1)) and lower-limit values (threshold Pu(n-1)=Pd(n-1)) corresponding to the respective wheel cylinder pressure setting values is set. The wheel cylinder pressure is controlled to the wheel cylinder pressure setting value corresponding to a range to which the detected brake operation state amount belongs.
