FIELD: vehicles.
SUBSTANCE: in the vehicle motor control method, it is actuated to perform power rotation, so that vehicle deceleration becomes less or equal to prescribed value, when fuel injection for engine stops during deceleration and engine rpm is greater than or equal to preset rotation speed. Vehicle engine and motor control device comprises a fuel cut-off control unit, when engine rpm is greater than or equal to preset rotation speed during deceleration and deceleration control unit actuating motor to perform power rotation, so that vehicle deceleration becomes less or equal to prescribed value when fuel injection for engine is stopped.
EFFECT: improved fuel efficiency.
