Abstract
An engine and a motor are provided. The engine and the motor are connected to each other through a first clutch whose transmitted torque capacity is adjustable. The engine is started by applying the first clutch and cranking the engine with a driving effort of the motor. A first start mode and a second start mode are employed. The first start mode is a mode in which the engine is started from rest in response to driver's accelerator operation. The second start mode is a mode in which the engine is started from rest in response to a factor other than driver's accelerator operation. The transmitted torque capacity of the first clutch during cranking of the engine is set smaller when in the second start mode than when in the first start mode.
