Driving control apparatus and method of hybrid vehicle

A driving control apparatus of a hybrid vehicle comprising:

• an internal combustion engine;
• a generator capable of performing power generation by power of said internal combustion engine and capable of charging a storage battery with electric power obtained by the power generation;
• a power dividing mechanism for dividing the power of said internal combustion engine into a drive shaft and a rotating shaft of said generator;
• an electric motor capable of outputting power according to electric power supplied from at least one of said generator and the storage battery, to the drive shaft;
• a changing device capable of changing an operating state of said generator, from one state to the other state out of a first state in which the rotating shaft of said generator can rotate and a second state in which the rotating shaft of said generator is fixed in a stop state;
• and
• a controlling device for controlling said changing device to change the operating state of said generator from the other state to the one state after changing the operating state of said generator from the one state to the other state, in a predetermined period in which the rotating shaft of said generator does not rotate.
