PROBLEM TO BE SOLVED: To improve the energy efficiency of a vehicle.SOLUTION: When an autonomous operation request of an engine is a pre-stopping autonomous operation request (an autonomous operation request when required power is reduced to a stopping threshold or less during a travel under an engine drive mode, establishing an engine stop condition), basically an ignition timing TF1 advanced from an autonomous-operating ignition timing TFidl that is set for an autonomous operation (an idle operation) is set as a target ignition timing TF* (S160) to perform engine ignition control (S170), until an intake air volume Qa is reduced to a threshold Qaref or less (S140). Further, power is generated by a motor using output from the engine. |
