ABSTRACT:
A brake controller is provided that includes a braking force application mechanism that presses a friction member against a braked member so as to apply a braking force to a wheel of a vehicle; and a control unit. The control unit calculates an index, which indicates a difference between an expected braking effectiveness and an actual braking effectiveness, corrects a target value, which is set to control a pressing force of the friction member, in accordance with the index to reduce a variation in a braking effectiveness of the vehicle. The control unit further sets a variation range in accordance with a factor that causes the difference. The variation range limits a variation in a correction amount to correct the target value.
