PROBLEM TO BE SOLVED: To improve a regenerative energy efficiency of a hybrid vehicle at deceleration. SOLUTION: The control apparatus differentiates a target state of charge TSOC at a constant-speed driving from that of decelerating driving, and sets a target state of charge for the steady-speed driving lower (TSOCL) and that of the reduced-speed driving higher (TSOCH) (21). The apparatus calculates a target charge current for a high voltage battery after detecting a state of charge of the high voltage battery and compare the actual state of charge SOC with the target state of charge TSOC. It further calculates a target generating current for a generating motor 2 (27) after detecting an electric load current supplied from a low voltage battery to the load of vehicle (26) and integrates the electric load current with the target charge current. It then controls an amount of electric generation of the generating motor 2. |
