1. A coordinated brake control system for a hybrid brake system including a regenerative brake unit and a friction brake unit for a vehicle, the coordinated braking control system comprising:

  • a controller 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,andto 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.
