PROBLEM TO BE SOLVED: To provide a braking control system exhibiting high replacement control responsiveness irrespective of whether a hydraulic braking device restricts occurrence of a master cylinder hydraulic pressure.SOLUTION: A braking control system is characterized in that a comprehensive controller includes a replacement control unit that when regenerative and collaborative braking control is implemented, if a driving wheel slip exceeds a pre-set slip threshold SLPlim, executes replacement control for decreasing a regenerative braking torque and increasing a frictional braking torque using a VDC brake fluid pressure unit, and a threshold designation block that is included in the replacement control unit, and that when a driver performs a braking maneuver, executes the pieces of processing of steps S101, S102, and S103 as follows: when occurrence of a master cylinder hydraulic pressure is restricted by restriction means, the slip threshold SLPlim is set to a value making a slip length relatively small; and when the occurrence of the master cylinder hydraulic pressure is not restricted by the restriction means, the slip threshold SLPlim is set to a value making the slip length relatively large. |
