<P>PROBLEM TO BE SOLVED: To solve the problem that excessive braking is caused when releasing brake because the braking force reducing speed of a hydraulic braking means is low when regenerative braking has priority to hydraulic braking with a point of view from energy economy. <P>SOLUTION: In the case wherein a target braking force is reduced in the state that the hydraulic braking force and the regenerative braking force are generated, when deceleration of a difference obtained by subtracting the maximum value of the possible regenerative braking force at each time point from a value of the target braking force at each time point is larger than the maximum value of d the braking force reducing speed of the hydraulic braking force generating means, the regenerative braking force at each time point is controlled so that a sum of the regenerative braking force and the described difference becomes a value of the target braking force at each time point by considering that the described difference is reduced at the maximum value of the braking force reducing speed of the hydraulic braking force generating means at each time point. <P>COPYRIGHT: (C)2008,JPO&INPIT |
