Abstract: In response to a DN operation that changes a shift position SP from a D position to an N position during forward drive in an HV drive mode, then an accelerator position Acc is not less than a reference accelerator position Aref (step S130), a mechanical neutral control is performed to provide a neutral state by releasing transmission of power between an intermediate shaft 32 and a driveshaft 36 by a multi-speed transmission 60 (step S230). An engine and two motors are then controlled to be rotated at rotation speeds close to rotation speeds Nedn, Nm1dn and Nm2dn at the time of DN operation (steps S250, S270 and S280).

Abstract: If an accelerator pedal is released, when a flag indicates 1, a vehicle travels in a traveling environment reflected operation mode where an engine and two motors are controlled in a manner that a required torque is output to a drive shaft while the engine is operated by the motor. If a vehicle speed is equal to or lower than a threshold at the time or after the flag is changed from 1 to 0, the vehicle travels in a normal operation mode where the engine and two motors are controlled in a manner that the required torque is output to the drive shaft with engine rotation stopped. If the vehicle speed is higher than the threshold when the flag is changed from 1 to 0, the vehicle travels in the traveling environment reflected operation mode until the vehicle speed becomes equal to or lower than the threshold.

Abstract: If an accelerator pedal is released, when a flag indicates 1, a vehicle travels in a traveling environment reflected operation mode where an engine and two motors are controlled in such a manner that a required torque is output to a drive shaft while the engine, in which fuel injection is stopped, is operated by the motor. If a vehicle speed is equal to or lower than a threshold at the time or after the flag is changed from 1 to 0, the vehicle travels in a normal operation mode where the engine and the two motors are controlled in such a manner that the required torque is output to the drive shaft with engine rotation stopped.
