Abstract
A brake controller is provided with a positive efficiency operation limiter configured to provide a time for maintaining or decreasing a torque to be generated by a motor, such that a braking force generated by pressing between a brake rotor and friction pads does not decrease, while a braking force command value outputted from a braking force command section increases. For example, the limiter limits a ratio of a time for increasing the braking force, relative to a sum of the time for increasing the braking force and the time for maintaining or decreasing the braking force, to a predetermined value or less.
