Beschreibung
Zusammenfassung:	The present invention relates to a hybrid vehicle control device which is capable of reducing motor torque during motor slip drive control when a driving force transmission system load is high. The hybrid vehicle control unit of the present invention comprises an engine (E), a motor generator (MG), a first clutch (CL1), a second clutch (CL2), a road surface gradient estimation and calculation unit (201), and an MWSC+CL1 slip control process unit (step S9). The motor generator (MG) starts the engine (E) while outputting a vehicle driving force. The first clutch (CL1) selectively engages and releases the engine (E) and the motor generator (MG). The second clutch (CL2) selectively engages and releases the motor generator (MG) and left and right rear wheels (RL and RR). The MWSC+CL1 slip control process unit is configured, when the driving force transmission system load is a predetermined level or above, to slip engage the first clutch (CL1) with the engine (E) remaining to operate at a predetermined rotation speed, and to slip engage the second clutch (CL2) with the motor generator (MG) being at a rotation speed lower than the predetermined rotation speed.
