摘要： Improved maneuverability, improved followability towards a target braking force and enhanced brake feeling when a low braking force is being effected may be achieved. A brake controller unit (2) may include a clearance estimator (13) which may be configured to use a rotational angle (θ) of a motor to estimate a clearance, inclusive of negative values, between a frictional material (45A), (45B) and a brake. A target braking force (F r ) may be compared with a switch-determining braking force (F rsw ), so that clearance control based on a target clearance (C r ) may be performed when the frictional material is in approximate-contact state corresponding to the target braking force (F r ) being low, and so that braking force control may be performed when it is equal to or greater than the switch-determining braking force (F rsw ).
