PROBLEM TO BE SOLVED: To provide a sufficient regenerative electric power without requiring two clutches. SOLUTION: Every gear change stage achievable by a transmission, in both coupling state and uncoupling state of a lock up clutch, an operation state for achieving a desired propeller shaft torque TPS* as a specific numerical value of a desired deceleration, for example a motor/power generator rotation speed NM/ G, an engine rotation speed NE, a motor/power generator torque TM/ G, an engine torque TE, and regenerative power are calculated, and an operation state is selected so that regenerative electric power is getting large as battery charging amount SOC is getting small. When this operation state satisfies a permission condition, the operation state is selected. When the operation state does not satisfy the permission condition, the other operation state satisfying a priority condition is selected. In response to the selected operation state, the operation state of the engine and the motor/power generator, an operation state of the lock up clutch, and the gear change stage of the transmission are controlled. |
