PROBLEM TO BE SOLVED: To provide a brake control device securing required braking force, avoiding a system down, even in the high-temperature condition or even in the condition wherein voltage is lowered. SOLUTION: This brake control device comprises a pump for increasing the pressure inside a wheel cylinder, a motor for driving the pump, a driving circuit for driving the motor, a power source for the motor, and a control unit for computing a target wheel cylinder pressure based on condition of the vehicle and outputting a motor drive command value to the driving circuit based on the target wheel cylinder pressure. The control unit detects one or both of voltage of the power source and temperature of the driving circuit, and in the case wherein voltage of the power source is lowered to a predetermined inclination reducing voltage threshold value or less, or in the case wherein temperature of the driving circuit rises to a predetermined inclination reducing temperature threshold value or more, a motor drive command value inclination reducing control for reducing inclination of the motor drive command value is carried out.
