<P>PROBLEM TO BE SOLVED: To improve drivability by achieving high-accuracy braking-force control by always generating an optimum braking force corresponding to a driver's intention regardless of a vehicle traveling state in a braking control device for a vehicle. <P>SOLUTION: A main ECU 112 controls a master cylinder 13 and hydraulic pumps 51, 52 by a brake ECU 116 on the basis of a braking force requested by a driver while allowing an electric motor 102 to be controllable by a motor ECU 111. The main ECU 112 changes distribution between a pressurizing braking force generated by the hydraulic pumps 51, 52 and a regenerative braking force generated by the electric motor 102 on the basis of deviation between the actual deceleration of a hybrid vehicle and estimated deceleration estimated from an amount of reduction in the pressure of master cylinder pressure generated by operations of the hydraulic pumps 51, 52. <P>COPYRIGHT: (C)2009,JPO&INPIT |
