Abstract:
Ina drive control apparatus (1) of a hybrid vehicle, a change rate restriction value of a target engine rotational speed which is set on the basis of a vehicle speed is preset, a restriction value of the target engine rotational speed is calculated from the change rate restriction value and a previous target engine rotational speed, a target engine operation point to decide the target engine rotational speed and a target engine torque is set on the basis of the restriction value of the target engine rotational speed and the provisional target engine rotational speed, a target electric power is calculated from a difference between a target engine power which is calculated from the target engine operation point and a target drive power, and torque instruction values of a plurality of motor generators (4, 5) are calculated by using a torque balance equation including a target engine torque which is obtained from the target engine operation point and an electric power balance equation including the target electric power.Thus, even in a transient state where the operation point of the internal combustion engine (2) is changed, since the target operation point line is traced, the fuel consumption can be improved.
