The target braking force calculator calculates the first target braking force portion and the second target braking force portion according to the contribution degrees and obtains the final target braking force by adding the first target braking force portion and the second target braking force portion.

Abstract: A vehicle brake control system has a braking detector and a braking controller. The braking detector determines whether a braking operation in a vehicle is within an initial braking stage based on a control condition of a frictional braking system. The braking controller performs initial braking stage control during the initial braking stage by controlling a regenerative braking system to provide a limited braking torque and the frictional braking system to provide a supplemental braking torque, the combination of which provides a target braking torque. The braking controller performs subsequent braking control when the initial braking stage ends to provide an increased regenerative braking torque and a lower supplemental braking torque as the target braking torque.
