A coordinated brake control system is for a hybrid brake system including
a regenerative brake unit and a friction brake unit for a vehicle and is
arranged to generate a total braking torque which is a combination of a
regenerative braking torque generated by the regenerative brake unit and
a friction braking torque generated by the friction brake unit, so as to
bring the total braking-torque closer to a target braking torque, and to
limit a rate of change of the regenerative braking torque according to a
response delay of the friction braking torque when a first distribution
ratio of the generative braking torque relative to the total braking
torque is decreased and when a second distribution ratio of the friction
braking torque relative to the total braking torque is increased.
