PROBLEM TO BE SOLVED: To obtain a drive control apparatus which prevents a power source (an angine and an electrically driven motor) from being blown up when a power transmission means such as a gearbox or the like is changed over from a drivable state to a nondrivable state while a hybrid vehicle is being run at a prescribed vehicle speed or higher and which prevents a shock or the like from being caused when the power transmission means is changed over to the drivable state after that in the hybrid vehicle in which the power transmission means is arranged and installed between the power source and driving wheels. SOLUTION: While a hybrid vehicle is being run at a prescribed vehicle speed αor higher, a power transmission means is changed over to a range N. Then, in a state that power is transmitted from a power source to driving wheels, an electrically driven motor is controlled at Step SA10 in such a way that the change rate |dN1 /dt| of the input speed of rotation N1 of the power transmission means becomes a prescribed value or lower. In a state of power-off that power is transmitted from the driving wheels to the power source, the electrically driven motor is controlled at Step SA7 in such a way that the ratio (N1 /N0 ) of the input speed of rotation N1 to the output speed of rotation N0 of the power transmission means is within a prescribed range corresponding to a transmission gear ratio. |
