<P>PROBLEM TO BE SOLVED: To compensate for, at high response by automatic braking, excess and deficiency of the braking force in transition from electric travel (EV) mode coasting travel to hybrid (HEV) mode coasting travel. <P>SOLUTION: In S11, power train output possible braking force tTbp capable of being generated by a power train during the coasting travel is calculated. In S12 and S13, a demand braking force Tbw and driving wheel target braking force Tbr of a vehicle are retrieved from master cylinder hydraulic pressure Pm. In S14, a target driving force tTFo0 (negative value is braking force) of vehicle is compared with the polarity reversal value of Tbp. When it is not tTFo0>-Tbp, namely when tTFo0 is achieved by Tbp, driving wheel target automatic braking force tTbr is set at 0 in S15. When it is tTFo0>-Tbp, namely when tTFo0 is not achieved by Tbp, tTbr = (Tbr-Tbp) is set in S16. Then, in S17, Tbw-Tbr is substituted for driven wheel target automatic braking force tTbf. <P>COPYRIGHT: (C)2007,JPO&INPIT |
