Abstract
A hybrid drive device includes a transfer torque estimation unit for estimating a transfer torque transferred by the lock-up clutch with the lock-up clutch slipping; and a target rotational speed determination unit for determining the target rotational speed of the rotary electric machine to be achieved in the rotational speed control on the basis of the transfer torque estimated by the transfer torque estimation unit, a target transmission device input torque of the transmission device determined on the basis of an operating state of a vehicle, and a turbine speed of the turbine runner, wherein the engine startup control device starts up the engine by controlling the rotational speed of the rotary electric machine to the target rotational speed determined by the target rotational speed determination unit.
