A control system for a hybrid drive unit for avoiding an overcharging and an over discharging of a battery when starting or stopping an engine. The control system selects a speed ratio where an amount of an electric power to be stored into the battery is large or to be discharged from the electric storage device is small if a state of charge of the battery is lower than a first threshold value (at step S4). The control system selects a speed ratio where an amount of an electric power to be discharged from the battery is large or to be stored into the battery is small if a state of charge of the electric storage device is higher than a second threshold value (at step S7).
