Abstract
A braking control device comprising: an operation amount acquisition device that obtains an operation amount for a braking operation member; a pressurizing unit that presses a friction member to a rotating member fixed to a wheel, by using an electric motor; a control that controls the output of the motor based on the operation amount; a pressing force acquisition device that obtains the actual pressing force of the friction member pressing on the rotating member; and a rotation angle acquisition device that obtains the actual rotation angle of the motor. The control: stores the correlation between the actual pressing force and the actual rotation angle; approximates a function map indicated by a second degree or higher polynomial based on the correlation; calculates a target rotation angle based on the operation amount and the function map; and controls the motor such that the actual rotation angle matches the target rotation angle.
