Drive control apparatus and drive control method for hybrid vehicles and hybrid vehicle

A drive control apparatus for hybrid vehicles adapted to output generated power at an internal combustion engine and a motor generator through a power transmission mechanism to drive axles, the drive control apparatus for hybrid vehicles comprising:

• an output shaft fixing mechanism operable to fix an end of an output shaft of the internal combustion engine as necessary to disable rotation of the output shaft;
• a request drive force setter configured to set up a request drive force depending on a driver's request;
• a stored energy level detector configured to detect a stored energy level of a battery;
• and
• a controller configured for a control to be executed in accordance with a condition based on a state of charge (SOC) of the battery to stop the internal combustion engine, use the output shaft fixing mechanism to stop the output shaft, and run the vehicle in an electric only mode using the motor generator regardless of the requested drive force.
