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 S), a mechanical neutral control is performed to provide a neutral state by releasing transmission of power between an intermediate shaftand a driveshaftby a multi-speed transmission(step S). An engine and two motors are then controlled to be rotated at rotation speeds close to rotation speeds Nedn, Nmdn and Nmdn at the time of DN operation (steps S, Sand S).
