1. A hybrid vehicle drive control apparatus, comprising:
- an electric power generator mechanically connected to an engine;
a drive motor driven by at least one of an electric current generated by the electric power generator and an electric current supplied from a battery;
a detector that detects a battery state of the battery; and
a controller that;
calculates a lowest limit value of the battery state based on a rotating state of the electric power generator; and
sets a target torque of the drive motor based on the lowest limit value of the battery state.
