<P>PROBLEM TO BE SOLVED: To further accurately grasp whether "backlash elimination" by an output of press-push torque in an electric motor for suppressing a "gear noise" of a gear mechanism in a hybrid vehicle having a constitution that an internal combustion engine and the electric motor are connected to an axle via the gear mechanism is performed. <P>SOLUTION: A backlash elimination determination means determines whether the backlash elimination in a power transmission mechanism in the stop of a vehicle and in an operation of the internal combustion engine is performed by using a backlash elimination determination reference value which is set according to a lapse time after the start of the operation of the internal combustion engine. <P>COPYRIGHT: (C)2013,JPO&INPIT |
